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

Uncover the rechargeable battery.

Disconnect a negative wire from the rechargeable battery.

Remove the lower cover and a mudguard (right).

Remove knot of the air filter.

Remove ignition coils.

Disconnect a ventilation hose.

Uncover a head of the block of cylinders.

Measure a valvate gap.

Turn a bent shaft clockwise so that the piston No. 1 was in compression step VMT.

Fig. 2.236. Order of measurement of valvate gaps

Measure a valvate gap in a point And (fig. 2.236).

If the gap does not meet standard, replace a pusher of the valve and adjust a valvate gap on average value.

Standard valvate 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 bent shaft on 360 ° clockwise so that the piston No. 4 was in compression step VMT.

Measure a valvate gap in B point (see fig. 2.236).

If does not meet standard, replace a pusher of the valve and adjust a valvate gap on average value.

Standard valvate 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.

Install ignition coils.

Establish knot of the air filter.

Establish the lower cover and a mudguard (right).
