Avoid over tightening the belt so as not to overload the bearings of alternator 3 and water
pump 5.
IGNITION SYSTEM
Ignition Distributor
Every 10,000 Km:
1. Check the working surfaces of breaker contacts 3 (Fig.
41). In case of heavy transfer of metal from one
contact point to the other, dress them with a flat
barette file. Do not eliminate completely the crater on
the breaker arm contact point. Check and, if
necessary, dress the contacts in the distributor cap and
on the rotor.

2. Use a piece of clean, gasoline- soaked chamois leather
or some other lint-free material to clean the breaker
contact points, the rotor, and the outer and inner
surfaces of the distributor cap.
3. Check the breaker point gap which should be 0.4+0.05
mm, for which purpose.
•
Shift the gearshift lever into the neutral.
•
Apply the parking brake;
•
Rotate the crankshaft with the starting crank to set cam 15 in the position at which the
breaker contacts are wide open.
•
Check the gap with a feeler gauge; if the gap differs from the rated value, loosen screws 4
and, using a screwdriver inserted into special slot 5, shift the breaker con- tact post as
required; adjustment eve, tighten screws 4.
4. Check ignition timing, for which purpose
•
Connect one end of the wire of a 12-V test lamp to terminal 6, and ground its other end.
•
Turn on the ignition and slowly rotate the crankshaft with the starting crank; with the
ignition set properly, the test lamp should come on when mark 4 (Fig. 42) on the
crankshaft pulley is aligned with mark 2 on the timing gear cover, and the contact of rotor
2 (Fig. 41) should be opposite the contact of the No. 1 cylinder on the distributor cap.
5. If the marks are not aligned at the moment the test lamp
comes on, adjust the ignition timing as follows.
•
Rotate the crankshaft with the starting crank to set it in the
position at which the rotor contact faces the contact of the
No. 1 cylinder on the distributor cap, and mark 4 (Fig. 42)
is aligned with mark 2 (in this position the piston of the
No. 1 cylinder will be 5" before TDC as measured in
crankshaft degrees);
•
Loosen nut 11 (Fig. 41) and turn distributor body 12
clockwise until the breaker points are closed.
•
Slowly rotate the distributor body counter-clockwise until
the test lamp comes on; in doing so, slightly press the rotor counter- clockwise to take up
clearances.

Stop the distributor body exactly at the moment the test lamp comes on (the breaker
contact points are at the beginning of opening phase).
