2.6.2. Check of thermal gaps in the mechanism of a drive of valves




Uncover the storage battery.
Disconnect a negative wire from the storage battery.
Remove the bottom cover and a mudguard (right).
Remove knot of the air filter.
Remove ignition coils.
Disconnect a ventilation hose.
Uncover heads of the block of cylinders.
Measure a klapanny gap.
Turn a cranked shaft clockwise so that the piston No. 1 was in VMT of a step of compression.

Order of measurement of klapanny gaps
Fig. 2.236. Order of measurement of klapanny gaps


Measure a klapanny gap in a point And (fig. 2.236).
If the gap does not correspond to norm, replace a pusher of the valve and adjust a klapanny gap on average value.
Standard klapanny gap (on the cold engine): 0,27–0,33 mm.

NOTE
Write down the measured values to choose the corresponding pushers of the valve for replacement.

Turn a cranked shaft on 360 ° clockwise so that the piston No. 4 was in VMT of a step of compression.
Measure a klapanny gap in B point (see fig. 2.236).
If does not correspond to norm, replace a pusher of the valve and adjust a klapanny gap on average value.
Standard klapanny gap (on the cold engine): 0,27–0,33 mm.
Establish a cover of a head of the block of cylinders.
Connect a ventilation hose.
Establish ignition coils.
Establish knot of the air filter.
Establish the bottom cover and a mudguard (right).
