Advice 1: How to adjust the valves KAMAZ

Sooner or later, but if the car comes the moment when the engine starts to be "something". Hear a strange knocking, falling output, heard "shots" of the muffler. To go to the car wash? Why rush, it is most likely misaligned gaps in valves and their adjustment is quite capable to make independently.
How to adjust the valves KAMAZ
You will need
  • - a set of wrenches and bits;
  • - the lever (crowbar, a small crowbar, etc.) for manual "crank" of the camshaft;
  • - torque wrench;
  • - feeler gauge for measuring clearances;
  • instruction manual for KAMAZ (IE).
Instruction
1
Close the fuel supply and carefully remove the hatch in the lower part of the housing for manual rotation of the crankshaft) and covers of the cylinder heads. Do not damage the gasket. Check with a torque wrench tighten the bolts to the cylinder block (19-21 kg/m).
2
Install flywheel end of the crankcase in a lower position. It is necessary to delay the lock and deploy the flywheel 90 degrees. Install the crankshaft in the position which corresponds to fuel injection at the 1-and 5-cylinder engine (see drawings and additional guidance in the IE). The crankshaft must scroll lever when inserting it into the hole located on the outer surface of the flywheel.
3
Check the tightness of the nuts on the posts of fixing the adjustable rocker arms of cylinders (4,2-5,4 kg/m). If necessary, retighten. Check the clearance between the valve tip and the rocker toe. The clearance should be such that a feeler gauge of 0.25 for the feed valve and 0.35 for prom, passed freely, and 0.3 and 0.4 and with stress. If the clearance does not meet these parameters, then adjust it using adjusting screws. Torque the correcting screw should be by 3.4-4.2 kgf/m.
4
Start the engine and listen to how it works. With proper adjustment of valves no knocks and unusual noises in the engine timing should not be. Reinstall the dismantled lid of the cylinder heads and Lucas Carter.
Note
Remember, check and adjust the engine valves must be made on the cold Assembly, otherwise, due to the expansion of metal when heated precise adjustment to produce will not succeed.
Useful advice
If all the above doesn't help, go to the car wash.

Advice 2 : How to adjust the valves on a truck

In the operation of KAMAZ, there may come a time when the engine there is a knock, the power drops from the muffler heard "gunshots". Of course, you can go to the car wash, however, repair is possible by yourself if only the valves are misaligned gaps.
How to adjust the valves on a truck
You will need
  • - wrench set with nozzles;
  • - the lever (a small crowbar, crowbar, etc.) to rotate the camshaft manually.
  • - feeler gauge for measuring clearances;
  • - torque wrench;
  • - manual of KAMAZ.
Instruction
1
First, you need to shut off the flow of fuel, then gently remove the manhole cover located in the lower half of the crankcase (to rotate the crankshaft manually), and covers of the cylinder heads. Be very careful, otherwise damage the strip. Using a torque wrench, check that bolts to engine block (19 to 21 kgf/m).
2
The flywheel of the crankcase install in the down position. To accomplish this, pull back the lock then 90 degrees to the flywheel. Crankshaft install position corresponding to the fuel injection for the first and fifth cylinders of the engine (look at the pictures, as well as additional information in the operating instructions). The crankshaft must be turned with a lever, crowbar, crowbar or similar item when inserting it into the located on the outside of the flywheel holes.
3
Using the same torque wrench, check how tight the nuts on the studs fixing the rocker arm of cylinders, subject to adjustment. The resulting value should fluctuate between 4,2 and 5,4 kg/m. If necessary, tighten the nut. Also don't forget to check the clearance between the toe of the rocker arm and valve tip. Its value must have a value such that the probe 0,25 to 0,35 feed valve and for the intake safely passed, and 0,3 and 0,4 – voltage. If the gaps this requirement do not match, correct them using special adjustment screws. The tightening torque of each adjustment screw should be equal to 3,4-4,2 kg/m.
4
Left to start the engine and listen to how it works. If adjusting valves is performed correctly, there are no knocking sounds and other extraneous noise in the gas distribution mechanism should not be audible. Install the dismantled cover of the hatch of the crankcase and cylinder heads in its place.
