Check of wear of cams

PERFORMANCE ORDER
1. Uncover a head of cylinders.
2. Install the piston of the 1st cylinder in compression step VMT.
3. Check wear of cams on the 1st cylinder. For this purpose install the indicator over the first yoke so that the leg of the indicator passed parallel to an axis of a bar and settled down directly over a bar.
4. Install the indicator on zero, turn the crankshaft in the direction of normal rotation. After indications cease to change turn the crankshaft to an arrow stop back. The difference of indications is equal to the cam size.
5. Write down indications and again install the piston of the 1st cylinder in compression step VMT.
6. Rearrange the indicator on other yoke of the 1st cylinder and repeat measurements.
7. Repeat measurements for other cylinders according to an engine operating procedure (see subsection 3.1.1).
8. Compare results to standard. If reduction of the size of a cam owing to wear exceeds norm, then replace a cam-shaft.

Check

PERFORMANCE ORDER
1. Remove a cam-shaft and wash out. Check a condition of necks. If on necks there are wear tracks, then are worn-out as well cam-shaft bearings. In this case the cam-shaft and bearings should be replaced.
2. If necks in satisfactory condition, then check their diameter in several places, define conicity and ovality.
3. Check the internal diameter of bearings of necks, define a gap and compare to standard. If the gap exceeds norm, then replace bearings (it is carried out in car service).
4. Check a condition of a gear wheel of the drive of the distributor of ignition. If there are signs of strong wear, then replace a cam-shaft.
5. Check a condition of cams, existence on them of a vykrashivaniye, zadir and deep development. Check the sizes of cams a micrometer. If cams in satisfactory condition and the size meets standard, then the cam-shaft can be used further.
