Store pushrods in the position in which they are installed in the head of the block.
Replace all pushers at the same time, as they cannot be adjusted and repaired.
Noisy operation of the pushers when starting the engine is normal. If, after warming up the engine, the noise does not decrease, it is necessary to check the pushers in the following way:
- start the engine and warm it up until the fan turns on;
- for two minutes, increase the engine speed to 2500 rpm;
- if the noise in the pushers is still audible, the faulty pusher should be found. To do this, remove the cover of the valve mechanism and turn the camshaft so that the cam protrusion above the tested pusher is directed upwards;
- press the pusher with a sharp stick, as shown in rice. 61, and if it turns out that the gap is more than 0.10 mm (until the valve opens), the plunger should be replaced.
Attention! The engine must not be started for 30 minutes after replacing the tappets, as this may cause the valves to hit the pistons.
