5. Tighten mounting clip nut "D" and bolt
"E" (1IIust. 29) securely. If the spark plug cables
have been removed for any reason, attach the
cables to the engine and magneto. Start by con-
necting the No. I cylinder spark plug to the
socket marked 1'1" on the distributor cap In
Illust.27). Then connect the No.3 socket with
the No.3 cylinder; next the No.4 socket with
the No.4 cylinder, and last, the No.2 socket
with the No.2 cylinder. See Illusts. 27 and 29A.
It is important that the breaker chamber be
kept clean because oil on the breaker points
will cause rapid burning. Remove the distri-
butor cap, distributor rotor, and the breaker
cover for breaker chamber inspection. See Illust.
30A. Care should be taken, when removing the
breaker cover, to keep dirt from entering the
breaker chamber. Be sure the chamber is
clean and that the breaker points are in good
condition and have the proper opening.
6. Connect the switch cable to the magneto
terminal. S.. "A", Illust. 29. Never use emery cloth or sandpaper to
clean the points. To dress the points. use a
sharp fine file. If the points are worn exces-
sively. replace both points.
7. To check the timing, crank the engine
slowly until the top dead center of the No.1
cylinder is reached; at this time the impulse
coupling should just trip. Never time before
top dead center.
Fill the recess in the breaker post with IH
High Temperature Grease (21372-D) and pack
a small quantity of the same grease iIJ back of
the breaker arm rubbing block and apply a
light coating of the same grease on the lobes
and flats of the breaker cam. See Illusts. 30A and 31.
See your International Harvester dealer.
8. The magneto is now correctly wired and
timed.
9. Push cable "B" back into the socket in
the coil cover. See Illust. 29A.
