Check of deterioration of cams

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

Check

PERFORMANCE ORDER
1. Remove a cam-shaft and wash out. Check up a condition of necks. If on necks there are wear tracks are worn out as well cam-shaft bearings. In this case it is necessary to replace a cam-shaft and bearings.
2. If necks in a satisfactory condition check up their diameter in several places, define конусность and ovality.
3. Check up internal diameter of bearings of necks, define a backlash and compare to the standard. If the backlash exceeds norm replace bearings (it is carried out in car-care centre).
4. Check up a condition of a gear wheel of a drive of the distributor of ignition. If there are signs of strong deterioration a cam-shaft replace.
5. Check up a condition of cams, presence on them выкрашивания, задиров and deep development. Check up the sizes of cams a micrometer. If cams in a satisfactory condition and the size corresponds to norm the cam-shaft can be used further.
