screwdriver, tighten the locknut and check the clearance for
correct setting;
- having adjusted the clearances of one cylinder, turn the
crankshaft through half a turn and adjust the clearances on other
cylinders (3, 5, 7, 8).
The valve-to-rocker clearances on a cold engine (15-20 °C)
for the exhaust valves of No.1 and No.4 cylinders (valves 1 and
8) should be equal to 0.30 - 0.35 mm, and for other valves - 0.35
- 0.40 mm.
Maintenance of the Lubrication System
For cooling oil in the engine lubrication system, an oil cooler
is provided. It is recommended to cut in the cooler by opening
the cock 7 (Fig. 22) at an ambient temperature above +20 °C.
But when riding on heavy roads (with heavy load and at a high
engine crankshaft speed), also cut in the cooler independing on
an ambient temperature.The level of oil in the engine crankcase
should be in register with the mark "Ï" on oil dipstick 3 (Fig.
16). Measure the oil level 2-3 min after shutting down a warmed-
up engine.
Drain oil from the engine crankcase right after the end of the
trip when the oil is still hot. This insures rapid and complete
drainage of oil.
For removing the oil filter 10 (Fig. 17), rotate it counter-
clockwise. When installing a new filter, make sure, that the
rubber sealing ring is in serviceable condition, lubricate it with
motor oil, and screw in the filter by hand till the sealing ring
would contact with the cylinder block surface, then draw up tight
