Examination
1. Install pushers.
2. Install the camshaft
3. Install the camshaft covers.
Note. Tightening torque: 11 Nm.
4. Place the valves of the corresponding cylinder in position «end of exhaust - start of intake» and check clearance (X).
Note. Size (At) depends on the thickness of the pusher (There are 25 size groups.)
5. Compare the obtained measurement results with the set values, and then replace the pushers, the gap in which does not correspond to the norm.
Note.
Clearance on a cold engine:
- Inlet: 0.125-0.25 mm.
- Release: 0.325-0.45 mm.
6. Remove the camshaft covers.
7. Remove the camshaft.
8. Remove the pushers, the gap in which does not correspond to the norm.
Determining the Y dimension
Note. The camshaft must be removed to replace the tappets after determining the required size (At).
1. Install the following assembly using the stand (KV113B0050 (Mot. 25201)) and a dial indicator, and then calibrate the indicator.
2. Raise the indicator probe (without changing the position of the holder), then insert it into the pusher to be measured. Write value (At) and repeat the measurements for the remaining pushers, the gap in which does not correspond to the norm. Choose replacement pushers from 25 existing size groups.
