3.5.20. Check of camshafts and pushers

Camshafts

PERFORMANCE ORDER
1. To measure a beating of camshafts, address the expert.
2. Examine necks of bearings of shaft on existence of scratches and wear tracks. If shaft are worn-out, replace them together with a head of cylinders. Measure diameters of necks of bearings.
3. Examine cams of shaft on wear existence. By means of a micrometer measure height of cams. If the size of wear of a cam exceeds admissible limits, replace the camshaft.
4. Measure lubricant gaps of bearings of camshafts by means of the plastic measuring instrument. If the size of a gap exceeds admissible limits, replace the camshaft and carry out a repeated inspection. If the result remained the same, replace a head of cylinders.
5. Determine width of the crushed plastic strip by the special table.

Pushers

PERFORMANCE ORDER
1. Examine surfaces of pushers on existence of wear, scratches and traces of an overheat. If one or several pushers are damaged, it is necessary to replace all pushers.
2. Measure external diameters of pushers and internal diameters of the openings corresponding to them in a head. Take away diameter of a pusher from diameter of an opening, and you receive the size of a lubricant gap. Calculate gaps of all pushers and compare them to technical requirements. If gaps of pushers exceed admissible limits, replace pushers or a head.
