1. Warm up the engine. |
2. Uncover heads of cylinders and establish the piston of the 1st cylinder in VMT of a step of compression (see subsection 3.1.3). Valves of the cylinder should rock freely. |
|
3. Measure shchupy gaps in valves specified illustrations. Shchup should pass between a yoke and a valve core under small effort. |
|
4. If the gap differs from norm, unscrew a lock-nut and, rotating a screw-driver the screw, establish the necessary gap. |
5. Holding the screw a screw-driver, tighten a lock-nut and again check a gap. |
|
6. Put labels on a pulley of the crankshaft and on a forward cover. Turn the crankshaft on 1 turn before coincidence of labels, measure and if necessary adjust gaps in the valves specified an illustrations. |
