3.2.11. Hydraulic тарельчатые pushers

THE GENERAL DATA

All diesel engines are equipped hydraulic тарельчатыми by pushers. Thanks to it noise in a drive of valves decreases and adjustment of a backlash of valves within the limits of maintenance service is not required.

Check work of hydraulic pushers in the event that at achievement by the engine of working temperature noise in a drive of valves proceeds.

PERFORMANCE ORDER

1. Pass with the heated-up engine. After achievement by a cooling liquid of working temperature continue movement on 5 km to provide sufficient temperature of engine oil.

2. If the hydraulic pusher still rustles, stop the engine.

3. Check up oil level in the engine: it should not be above a mark "max" on маслоизмерительном щупе at all.

4. Remove a cross-section pipe of the air filter.

5. Uncover heads of the block of cylinders.

6. At the control тарельчатого a pusher of top of cams of inlet and final valves of the corresponding cylinder should be in the top position. In this case corresponding pushers are unloaded. As unnecessary проворачивание the engine promotes subsidence of an element of indemnification of a backlash of the valve, it is expedient to begin the control with the cylinder standing in ВМТ of ignition.

7. Press on тарельчатый a pusher a wooden or plastic core in a direction downwards and check up an air backlash. If thus the air backlash is more 0,4 mm and pusher moves downwards easier, than others it is necessary to replace it.

8. Turn a camshaft so that cams of the cylinder subject to check have been directed upwards. For this purpose establish a transmission on idling, tighten a lay brake and turn a cranked shaft for a bolt of fastening of a gear wheel of a camshaft.

9. If at check тарельчатый the pusher is pressed downwards easier, than others or if on a cam circle there is a backlash, check up a condition of apertures for access and oil plum, having disassembled a pusher (work for repair shop).

10. In case of need disassemble a camshaft and replace тарельчатый a pusher.
11. Establish a cover of a head of the block of cylinders.
12. Establish a cross-section pipe of the air filter.
