Removal procedure
1. Remove the rocker arms from the corresponding cylinder head. See «rocker» in this section.
Attention!
- The plunger of the stationary hydraulic valve clearance compensator should not be moved (1), if there is no oil in the low pressure chamber.
- After filling the stationary hydraulic valve clearance compensator with oil, it is not allowed to turn it over or press the plunger.
2. Remove from cylinder head (2) stationary hydraulic valve clearance compensator.
Cleaning and inspection
1. Inspect the stationary hydraulic valve clearance compensator, checking for the following faults:
- blockage of the oil passage (1),
- scratches or wear at the rocker contact area (2),
- damaged or broken latch (3),
- severe scuffing or wear of the compensator body (4).
2. Replace compensator if required.
Installation procedure
Attention! It is necessary that each compensator (1) was filled with clean engine oil and it is not allowed to turn the compensators over and press the plunger before installation. Lack of oil in the low pressure chamber of the compensator or movement of the plug without lubrication will allow air to enter the high pressure chamber of the valve lifter. The pressure chamber of the compensator cannot be vented, causing cavitation and severe damage to engine components.
1. Fill the stationary hydraulic valve clearance compensator with clean engine oil. Care must be taken not to scratch the spherical bearing surface of the compensator.
2. Lubricate with clean engine oil the channels in the cylinder head designed to feed the compensator.
3. Install compensator in cylinder head (2).
4. Liberally lubricate the spherical bearing surfaces of the compensators with conventional camshaft / tappet prelubrication.
5. Install rockers. See «rocker» in this section.
