Inside the car
· Operation of lights.
Dip to main beam working, including the operation of the main beam warning light on dash (shows in blue). The operation of the rear fog light switch making sure in stays on and switches off, with the warning light showing up either on the dash or on the switch. Indicator switch is operated to make sure the warning lights are displayed on the dash and cancel ok.
· Horn operation. Must be audible.
· Wiper and wash operation. Must operate and washers must work and hit the screen, and wipers must clear the screen.
· Anti-lock braking system (ABS) if fitted. To check this, turn the ignition on, but don't start the engine. The light should be visual on the dash, with the engine running it should be off. (With Range Rovers and Land Rovers the light does not go off until you are moving).
· Foot brake operation. With this the tester will be checking the operation of your brake servo. With the engine off, operate the foot brake several times until the pedal goes hard. With your foot resting on the foot brake start the engine; you should feel your foot sinking on the brake pedal, which shows you the servo, is operating, as it should do.
· Foot brake and clutch pedal. Must have grip rubbers on the pedals to stop your foot from slipping off. · Handbrake operation. Must stay on and release with free travel still left in handbrake mechanism.
· Operation of front doors. Should be able to open both front doors from inside.
· Front and rear seats. The tester will check the security of the backrests to make sure they don't fall forward of there own free will, and will check the base for security on the anchor points.
· Play in the steering column. Must be no excessive play in the steering column bearings. To check this the tester will hold the steering wheel at these points on the steering wheel, which is at 15.00 and at 21.00 and will rock the steering wheel side to side and then will do the same at these points, 0.00 and at 18.00. Side movement would be next, in which the tester will move the steering wheel from lock to lock to check for free play in the steering system. You are allowed a certain amount, which normally occurs with vehicles fitted with steering boxes.
Out side the vehicle
· Checking the windscreen for defects. The examiner will check for cracks and stone chips. UK law is that anything bigger than 10mm in diameter on the drivers; side is a failure. Drivers side being zone A, which is from one side of the steering wheel to the other side of the wheel with vertical lines going up the screen. Zone B is passenger side, which should have nothing bigger than 40mm in diameter.
· Checking the wiper rubbers. By lifting up the wiper arms of the screen you can check the rubbers for damage. They should not be coming away from the blade, as this is a failure.
· Operation of doors. Must be able to open all doors from the outside and should be secure when shut.
· Seat belts. The examiner will extend all the seat belts fully and check for fraying and cuts to the webbing. Lastly fasten all the seat belts into their stalks making sure they are secure and cannot be removed until you press the release button.
· Checking structural points. With this, the examiner will check the top of the sills and the A and B pillars for any rot, which could weaken the vehicle, including seat belt anchorage points. Also will check the boot floor and rear panel for any rot.
· Checking the lights. All lights must work except the reverse lights and front fog lights, which are not a legal requirement. Failures on this are, bulbs not working, reflectors, which are broken and missing. Indicator bulbs showing a white light that's if the lens is clear plastic. Faded colour lenses or incorrect colour given, by having a broken lens or all lights incorrectly displayed at the same time, normally caused by a bad earth in the system.
· Headlight aim. This is one of the points you will not be able to check, as only the garages would have this equipment to check this.
Under the bonnet
· Structural check. Checking top shock absorber mounts for corrosion, and chassis. Slam panel at the front close to structural mounts. Bulk head for corrosion especially around the brake servo area.
· Brake pipes. The examiner will ask the assistant to operate the brake pedal with the engine running, firstly checking the brake fluid level then going onto checking for leaks from the system including brake servo vacuum pipes and also looking at brake pipes for excessive corrosion which could lead to brake failure and security. To fail pipes they must be badly corroded and also they tend to loose their thickness down to that fact. Please note it is down to the examiner to determine whether to pass or fail the pipes.
· Steering. Asking the assistant to rock the steering from lock to lock the examiner will be looking at the lower steering column universal joint (U/J) that's if one is fitted for any free play or a rubber mounting for any defects where it goes directly onto the steering rack or steering box.
Under the vehicle
· Exhaust system. Must be free of excessive leaks, i.e. cracked pipes or cracked silencers or joints, also must be secure on all mounts.
· Brake pipes and brake hoses. Looking for excessive corrosion and security as before on brake pipes and must not be fouling moving parts. Brake hoses must be free of deep cuts and bulges. Rule of thumb with brake hoses, to check cut bend hose to see if you can see the cord showing. If you can then it would be a failure. If in doubt! Then ask a garage.
· Brake load valve. This is fitted on the rear axle, which determines the amount of force applied to the rear brakes when you have weight in the back of the vehicle. To check this it, the arm must move on the valve via the spring attached to the axle.
· Chassis. This is pretty hard as there are certain set ups. Most four wheel drives have a separate chassis away from the floor pan while a car can have this integrated to all in one, making the outer sills a structural point of the vehicle. So if in doubt ask. Anyway the main point is this. You need to keep an eye out for major rot near structural points, like suspension plus sub-frames, steering, seat anchorages and seat belt anchorages. If in doubt! Then ask a garage.
· Suspension. There are various set up's for suspension, the most popular is independent suspension where each wheel as its own suspension arms, from a torsion bar going across the rear axle, to a leaf spring set up used on each individual wheel on the rear axle.
I think that is enough to be going on with, so I will tell you what to look out for on each individual one.
On independent suspensions, you will need to check all suspension bushes for condition and wear using a lever bar with the suspension hanging down and not under load.
The torsion bar set up is found on the rear of the vehicle, joining both the rear wheels together on the same axle. As with independent suspension it must be hanging down and free from load. You need to check the axle bushes for wear.
Leaf springs are normally found on the rear of the vehicle. The things to look out for are; cracks in the leaf springs, broken U- bolts and loose U- bolt nuts, which tighten them to the axle. Also you will need to check the shackle bushes for wear, which support the leaf spring at the front and the rear. To check this you will need a certain amount of load on the vehicles axle.
There are various set up's on shock absorbers where they are independent from the coil springs or the most popular which is when its integrated with the coil spring, which is commonly called a suspension strut. With shock absorber and suspension struts shocks you will need to look for leaks, the condition of the top and bottom shock absorber mounts for wear, also the operation comes into play. To check this the vehicle must be on the ground. Using your weight bounce up and down on vehicle on the side you want to test, and then let go and count the amount of times it takes to settle. You will need to look for no more than two bounces. (To check top strut mounts see Steering) Looking at the coil springs you will need to check that they are not broken, through corrosion and are sitting correctly.
Now onto Anti-roll bars, which are a part of a typical suspension system, this helps the vehicle on cornering and gives the vehicle good stability. This is a metal bar, which goes across the front of the vehicle and rear if fitted, joining both the front suspension arms and rear suspension arms together via links on the lower suspension arms. The actual anti-roll bar is also attached to either the sub-frame or body of the vehicle through rubber mounts. You need to check the links for security and wear, either in the ball joints top and bottom or rubber bushes for separation. The anti-roll bar support bushes will also need to be checked for condition and separation.
· Handbrake cables on the rear must be in good working order and must not be frayed. The cables must be supported via the brackets to the body.
· Steering. There are mainly two types the most common is rack and pinion, which is where the steering column goes directly into the rack, which then goes to your front wheels. The other is a steering box, which is commonly used on four-wheel drives, vans and heavy goods vehicles. This is when the steering column goes directly to the steering box, which then uses steering arms from there to your wheels.
Rack and pinion; With the vehicle still jacked up and resting on axle stands, you will need to check lower and top (If fitted) suspension arm ball joints which are attached to the hub assembly for wear using a lever bar, using the tyre to lever up on. Sometimes in this situation you will find no movement but if you jack up the suspension arm from underneath and lever up on the tyre any movement will show up. Next you will need to check the steering track rod end ball joint, this shows up when you move the steering from side to side using the wheel. You will need to look for play in the ball joint and steering arm coming from the steering rack. Sometimes you do get a certain amount of play in the steering rack arm, but as long as it's not excessive it should be fine. If in doubt ask a garage.
Steering rack gaiters on the steering rack need to be checked. The covers should be free from splits and secure on the rack.
Steering box; As above with the vehicle on axle stands, you will need to look at the drop arm ball joint coming down from the steering box as well as checking all steering rod ball joints and track rod end ball joints for wear plus checking the lower and upper suspension arm ball joints which are attached to the hub assembly.
Wheel bearings; The two things to check for are free play in the bearing and noise. Firstly at 12.00 o'clock and 6 o'clock positions on the tyre rock the wheel to check for play, which should be minimal. You're aiming at 1-5mm play. For noise, spin the wheel to check for rumbling noises coming from the wheel bearing.
Tyre condition; You will need to check all tyre sizes on the vehicle, excluding the spare for correct size, secondly checking the condition of the side walls for bulging and cracks which could show up the internal cords of the tyre, and thirdly the tyre tread for wear. U.K law states the tyre must have 1.6mm tread across three quarters of the tread. This has always been a sticky subject, so if you're not sure ask a garage.
Brakes; At this point the examiner will check your brake discs and pads for condition. The rule of thumb is if the examiner can visually see your pads then they will be checked. If the examiner can't see with out taking the hubcap of or the wheel then they won't be tested. To fail pads they would nearly need to be close to metal to metal with the disc. For brake discs they would need to be badly worn or badly corroded. Brake calipers are also checked for leaks and security.
Vehicle on the ground
Emissions; This is one of those items you can not check, the only thing you can check for is excessive smoke from the exhaust caused by engine wear (blue smoke) it has to be pretty bad to fail, in other words you can not see the vehicle behind you. Other than that it's down to the garage to test your catalytic converter for operation.
Brake roller test; Sorry folks, yep this is another test you can not perform as the garages can only do this on there equipment, but you can do a simple test and that's to make sure the vehicle is braking in a straight line. In other words the steering wheel is not pulling to one side when under braking, this will show up any binding brakes on the front.

Why And When To Replace Valves and Timing Chain
Almost any dirt biker you meet today will agree that four-stroke dirt bikes are expensive when it comes to rebuilding them, especially if you have a shop do it. They have a lot more moving parts in the engine than a two-stroke engine does. This means Butterfly Valve that there are more things that can go wrong, and when something does break, it results in a domino effect that often grenades most, if not the entire engine.
There are ways to prevent these expensive repairs from happening. So instead of having your bike in the shop or sitting in the garage for weeks, or even months because you don't have the money, time, or parts, you could still be riding because you did some "preventative maintenance".
If you do a little research, you'll see that valves can get fairly expensive, considering you usually have to buy four or five of them. What will cost even more is when one of them breaks and puts a hole in your piston, resulting in a destroyed top-end. As far as timing chains, this is probably the most disregarded part in the top-end when it comes to maintenance. Many people think that timing chains will last hundreds of hours without failure because they're just spinning on the crank and cam(s). Well with the crank spinning from 1,500 rpm up to 12,000 rpm, and constantly accelerating and decelerating, the cam/timing is going to wear out eventually. When it does have to snap or break, it will seize the engine and more than likely destroy most of the parts.
Now I'm not trying to scare you, or to try to convert you to a two-stroke. I just want to inform you so that you know how to prevent something like this from happening. Now that you know why to replace these things, you should know when to replace them, otherwise it will do you no good.
Are You Racing Your High-Tech Four Stroke?
If you race and actually ride your 250/450F hard, then it's going to cause more wear on parts a lot quicker. Some bikes are different, and some valves can be defective, but I'm not going to say any names (Hon...da.....cough...cough). When racing, I recommend that you check the valves every 15-20 hours. Doing so will give you an idea about how long they may last. If everything seems good and they are still in-spec then you can screw everything back together and ride some more. If they are slightly out-of spec then you know they're starting to wear out, but should still be good. HotCams makes a Valve Shim Kit (VERY useful if you deal with a lot of 4-strokes) which makes adjusting easy.
When to actually replace valves is often the harder question. Some bikes can go a couple hundred hours with the valves still in spec, but that is very unlikely if you are racing. I suggest you replace the valves around 40-60 hours. Hard starting is a common indicator of at least a valve adjustment because they are tight and out-of spec. If you are racing then it would be safe to just replace them when this happens. It may seem like a lot of work, but trust me when I say it's cheaper to adjust or replace your valves every so often then letting them go until you drop one and grenade the engine.
What If I Trail/Play Ride?
Like I said earlier, I've heard of many people going 150+ hours on their four-stroke motocross bikes and still be good, especially on 450F's because you don't have to ride them as hard. I recommend, as long as you aren't riding every single day, checking your valves about once a year. If they are in-spec then you should be go to good for some more riding. Adjust them if they are out of spec.
If you've adjusted your valves 2-3 times, then it's probably time for some new ones. If you wait another time to adjust them it could be catastrophic.... If you have never had to adjust the valves on your four-stroke dirt bike, it's kinda' up to you on how long you want to go. I would replace them every couple seasons if I'm just trail riding, or after 100-200 hours.
What Is THE MOST Disregarded Part In Four-Stroke Engines?
Timing chains are the most forgotten part when doing maintenance on a four-stroke dirt bike engine. Why is this little chain so important? The big deal is that it can break and blow up your engine, 'nuff said! Now if you replace it every so often it will prevent that from happening. I explained earlier how timing chains get worn over time because of the abuse they get from the high-rpm engines. Not only can they break from fatigue, but after so much wear and tear from spinning on the crank and cam(s) it will get loose.
When the cam/timing chain gets loose it can slip and cause the teeth on the cam sprockets to jump. The timing is then changed, resulting in poor performance. If it jumps too much then the valve(s) can eventually hit the piston because the timing is so far off. And when that happens, it's over for good.
Now do you get the idea about why it is so important to replace the timing chain? I recommend replacing it every 100 hours of ride time. That's usually every year, unless you ride a lot more. It's a cheap part, and fairly easy to replace. It can save you hundreds in the long run if you just replace it after so long. Just call it 'cheap insurance'.
Now you may disagree with me, but it's pretty much a proven fact that Yamaha has been making the most reliable 250 and 450cc four-stroke motocross bikes. The other colored bikes would not last quite as long. But, within the past few years they have all stepped it up and got A LOT better. So keep this in mind when you're in the market for a used dirt bike. If you are looking to buy a new 250F or 450F, then it's pretty much pick a color and ride.
Have fun, and don't forget to do "Preventative Maintenance"!!!

The best way to Endure in Aluminum Market place
If we can easily make full utilization of every kind of valuable materials, we can actually delight in a much better existence. Commonly, we elect to implement many of the natural means to provide every kind of beneficial equipment and machines. In such a case, we are able to make our everyday living come to be a lot more snug and easy.
Amid all the valuable natural resources, the industrial aluminum profile is among the most handy and popular a single. As a way to make extensive use of it, men and women also opt to blend the aluminum with other supplies. In such cases, the new supplies can serve us improved.
Since the aluminum and also the aluminum alloy are very well-known presently, a lot more folks elect to promote these components since they are financially rewarding. Nonetheless, the aluminum current market has intense opposition now. In an effort to survive within the intense opposition, it is rather critical in your case to find out some expertise.
In case you are a businessman who does the aluminum coils for sale enterprise, you'll be able to recognize that significant orders can bring you numerous of money. Typically, the massive orders come from massive shoppers. They often must wholesale loads of aluminum products and goods.

Top Notch Actuator and Valve Parts for Your HVAC Unit
The actuator and valve parts for your HVAC unit are very important to the functionality of your unit. The outside unit of your heat pump consists primarily of the condenser coil, a compressor and a fan. Most of the hard-working equipment is housed within the inside unit.
Any time your heat pump requires repair or maintenance, the technician will connect pressure gauges to make sure there is the correct amount of coolant. Liquid coolant will be added through a port on the outside unit if needed. Leaks are relatively rare, but they do occur. Occasionally coolant, also called refrigerant, will need to be drained and refilled.
Actuators and Parts
An actuator, by definition, is a mechanical device ZD Valve for moving or controlling a mechanism or system. Operated by some source of energy, it converts energy into motion. Consider the wheel and axle for example. Rotating the axle causes the wheel to move; and as a direct result, causing whatever is attached to the wheel to move as well.
Energy created by hydraulic fluid, electric current or pneumatic pressure may be converted into motion using an actuator. The actuator in your HVAC unit is likely controlled by electric current. They are used most commonly for inflow-control valves, pumps, motors, relays, switches and positioning drives.
The two most common types of actuator are hydraulic and electro-servo. A hydraulic actuator forces hydraulic fluid through cylinders or motors and is controlled by control valves. Hydraulic machinery produces very high amounts of power and makes use of a variety of actuators in the process.
A pneumatic actuator compresses air to use as its source of energy. They contain a piston, cylinder and valves. The piston is protected by the diaphragm, which keeps the compressed air in the upper portion of the cylinder. Air pressure pushes the diaphragm down, which moves the piston down as well.
Control Valves and Parts
Control valves are used to control the flow, pressure, temperature, or liquid level of various mechanisms. The valve may be partially opened or closed in order to maintain proper flow, pressure or temperature, as it does with your HVAC system. Control valves are generally opened or closed by using an electrical, hydraulic or pneumatic control system.
Valve bodies vary depending on their intended use. Angle valves consist of cage-style and disk-stack style bodies. Globe valves may have single, double or triple-way bodies as well as port guided single-port, balanced-plug cage-guided or high-capacity cage-guided bodies. Rotary style bodies include butterfly, v-notch ball control, eccentric-disk control, eccentric-plug control valve bodies.
Control valve parts for your HVAC unit should always be purchased from a certified dealer or other trusted source. Replacing valves or parts isn't always an easy job and should be handled by a professional with experience.
Cost
Most replacement parts are relatively inexpensive. The most expensive part to replace is the compressor. It could cost several hundred dollars to replace a condenser. People often choose to replace the entire unit in lieu of simply replacing that single part.
The fan, control valves and actuators are fairly inexpensive to replace if they become worn out. They are in fact moving parts, so they do tend to wear out more quickly than parts that are stationary. Contact a professional HVAC technician if you feel that your heat pump or other HVAC Gate Valve unit isn't functioning to its potential.
Any time your heat pump requires repair or maintenance, the technician will connect pressure gauges to make sure there is the correct amount of coolant.
