•
Holding the distributor body in this position, tighten nut 11.
•
Switch off the ignition, install the distributor cap on its body, and secure it with two spring
catches 7.
On a new car, check the breaker point gap and ignition timing after the first 2,000-3,000 Km.
Every 20.000 Km deliver 2-3 drops of engine oil into the hole of lubricator 14.
Spark Plugs
Every 10,000 Km proceed as follows:
Fig 43. Checking spark plug gap
1. Using gasoline and a stiff brush, remove carbon deposit
from the spark plugs.
2. 2. Check the spark plug gap with a round wire feeler gauge.
The gap should be 0.5-0.6 mm (Fig. 43); the gap must be
adjusted only by bending the side electrode.
Every 20,000 Km replace the spark plugs with new ones. For re- liable starting of the engine
at low sub-zero temperatures, it is recommended to replace the long-used spark plugs with
new ones, even if the used spark plugs are still serviceable; they can be used again in warm
seasons of the year.
TRANSMISSION
Clutch Fluid Reservoir
Every 10,000 Km check fluid level in the reservoir (Fig. 44) and
replenish, if necessary, to the lower edge of the filler neck.
Add HeBa (Neva) or Tomb (Tom) brake fluid only. It is recommended
to change the brake fluid with fresh one after five years of service.
Adjusting the Clutch Control Mechanism
Every 30,000 Km (and also after the first 2,000-3,000 Km and 10,000 Km if the car is new)
check and, if necessary, adjust the clutch control mechanism for which purpose.
Check clearance between pushrod 3 (Fig. 45) and piston 2 of master cylinder 1 which should
be 0.1-0.5 mm. The clearance corresponds to the travel of pedal 5 through 0.4-2 mm and it is
adjusted with stop 4.
Fig 45. Adjusting Clutch control mechanism.
1- Clutch master
cylinder, 2- pushrod piston, 3- pushrod, 4- pedal travel stop, 5- clutch
pedal, 6- operating cylinder pushrod, 7- clutch release fork, 8- nut, 9-
locknut, 10- operating cylinder.
Check free travel of pushrod 6 of operating
cylinder 10 which should be 4-5 mm. Pushrod
free travel is adjusted with nut 8 after loosening
locknut 9. Adjustment over, tighten locknut 9.
Upon completion of the above adjustments free
travel of the clutch pedal before the beginning of
clutch release should be 25-35 mm. Check the
clutch pedal free travel also after the bleeding of
the hydraulic control system. Presence of air in
the system is indicated by the spongy pedal and
incomplete release of the clutch (clutch drags).
Bleed the system through the union of operating
cylinder 10 in the same way as the brake system.
