Height of raising of a cam of the camshaft determines the size of opening of valves in view of what wear of cams exerts direct impact on efficiency of functioning of the engine.

Measurement of height of raising of a cam can be performed in two ways (depending on existence near at hand of the corresponding tools).

Determination of height of raising of cams by means of the measuring instrument of dial type

 PERFORMANCE ORDER

1. Determination of height of raising of a cam by means of the dial measuring instrument of plunger type can be made by in situ (without removal of a shaft from the engine). Measurement are made for each cam separately.
2. For the purpose of ensuring access to the camshaft uncover a head of cylinders.
3. Fix the measuring instrument so that its working plunger appeared directly over a surface of the cam which is subject to check.
4. Turn the engine so that the cam of the camshaft was developed by a heel down and nullify the measuring instrument.

The engine can be turned remotely by means of a starter, or manually for a bolt of a pulley of a bent shaft. Remember that the bent shaft can be turned only in the normal direction!

5. Slowly continue to turn a shaft until the pusher does not fall into most lowered state (full opening of the valve).
6. Consider the maximum instrument reading and compare its admissible values specified in Specifications.
7. If what wear from cams exceeds the limit of admissible range, the shaft is subject to replacement complete with pushers of valves.
8. Having finished check, remove the measuring instrument and establish into place a cover of a head of cylinders.


Measurement by means of a micrometer

 PERFORMANCE ORDER

1. Assessment of degree of wear of cams of the camshaft by means of a micrometer can be made only after preliminary dismantle of a shaft.

2. Measurement is performed in two steps. At first the full working height of a cam (Y), then its width (X) (basic diameter of the clown) is defined. For determination of height of raising of a cam it is necessary to subtract result of the second from result of the first measurement.

3. Compare results of calculations to requirements of Specifications. At wear any of cams below an admissible limit the shaft is subject to replacement assembled with pushers of valves.
