Figure 116. Valve with hydraulic tappet (cross section): 1 - pressure pin (rod); 2 - retaining ring; 3, 5 - pressure springs; 4 - ball; 6 - guide bushing; 7 - ball guide
Removing hydraulic valve lifters (figure 116) must be carried out in the following order:
- remove the camshaft (subsection 2.12.6);
- using a suction cup, remove the pusher or pushers from their wells in order and immediately mark their belonging. When installing, lower the pushers into their wells in case of reuse. Install the camshaft (subsection 2.12.6) and all other parts in the reverse order of dismantling.
Figure 116 shows a section of a valve with a hydraulic tappet and compensator, giving an idea of the arrangement of the parts.
