17.19. Check and adjustment of gaps of valves

Annually or each 20 000 km of run

This procedure does not belong to the M10 engine which has automatic regulators.

Gaps of valves can be checked both at warmed up, and at the cold engine, but keep in mind that the received sizes should differ depending on engine temperature. If you are going to carry out procedure of check and adjustment of gaps at the warmed-up engine, it is necessary to start it, to warm up to normal working temperature and then to switch off.

If gaps of valves are regulated at the warmed-up engine, it is necessary to be especially careful to avoid burns.


 PERFORMANCE ORDER

  1. Uncover heads of cylinders the engine (see. A part the Repair work which is carried out without extraction of the engine from the car).
  2. Turn the engine so that the forward piston No. 1 was in the top dead point (VMT) of a step of compression (see. A part the Repair work which is carried out without extraction of the engine from the car).
  3. Check gaps of valves for the cylinder No. 1. Demanded sizes of gaps are specified in the Size table and adjusting data at the end of the Management.
  4. The gap is measured by an insertion way щупа a measuring instrument of the demanded size between the end of a rod of the valve and the adjusting clown of the lever of the valve. Shchup should pass in a gap with some resistance.
  1. If the gap is too great or too small, weaken a lock-nut, insert a hook from a thick metal wire and turn the clown before achievement of the necessary gap.
  1. After gap installation reliably tighten a lock-nut, holding the clown in reached situation with the help of a hook. Once again check gap size - sometimes it slightly changes after a lock-nut tightening. In this case adjust it to the necessary size.
  2. On M10 engines valves are regulated in an operating procedure of cylinders, namely 1-3-4-2. After adjustment of valves of the first cylinder turn the crankshaft on a half of turn (180 °), then check and adjust valves on the third cylinder. Repeat procedure on other cylinders.
  3. On engines M20 and М30 valves also are regulated in an operating procedure of cylinders, namely 1-5-3-6-2-4. After adjustment of valves of the first cylinder turn the crankshaft on a turn third (120 °), then check and adjust valves on the fifth cylinder. Repeat procedure on other cylinders.
  4. Establish a cover of a head of cylinders (use new laying) and tighten fixing nuts exactly and reliably.
  5. Start the engine and check, whether there are no leakages of oil between a cover of a head of cylinders and a head of cylinders.
