Each car requires periodic adjustment valves.If this is not done in time, the machine will begin to lose its traction, noise will drive and increase the load on the remaining parts of the engine.To avoid this, you must promptly adjust the valve.How to do it, find in today's article.
valve clearance adjustment with his hands
The first thing to understand is a caveat.Check and adjust valve clearance must be carried out on the engine has cooled down.Recommended temperature of experts for issuing clearance is less than 38 degrees.
After our engine has cooled down, you can start adjusting.First we need to remove the cylinder head cover, then turn the engine up until the first cylinder shall not enter into the position of BMT.We should pay attention to the label.It is important to match with a pin on the oil pump pulley.
should also pay attention to the pushers intake and exhaust valves.Devices in the first cylinder should have a small gap, and on the 4th - be tightly clamped.If this did not happen, turn the engine one more revolution.
Now we take a special probe and measure the clearance between the valves.Ideally, it should not be much to slip or get stuck.The probe should be held away with little effort.If the device safely flies through the gap or, on the contrary, it stuck halfway, so you need to adjust the valve.In this case, we take the two open-end wrench (usually 13 and 17 mm) and release the lock nut on the adjustment screw.Now you can safely put the necessary clearance.
What gap should be?
It should be noted that absolutely all the cars the value is 0.15 millimeters.Moreover, this value does not depend on what's inside the car gas distribution mechanism.
How often you need to adjust the valve?
expose the gap should immediately after clear signs were seen.This loss of power dynamics characteristic "shots" of the exhaust pipe and so on.If we talk about numbers, it is necessary to adjust the valves every 20-30 thousand kilometers.If the last mark you, there was not exhaust or power loss, still check the clearance between the valves.So you can be sure that your iron one is in good condition.
also after issuing the necessary clearance can be replaced with shims on the upper side pushers.To do this, turn the crankshaft and is pressed into the plunger with a special tool.After that, we take out the washer.This can be done using a small screwdriver or a magnet.But before you squeeze it back, turn the unit before applying it to the candles on the top side.Ideally, there should pull over just two pusher.
Once the gap has been exposed, we collect everything in reverse order and check the operation of the engine.It shall make any clicks during operation and other characteristic sounds.
