Breaker Point Opening Gap:
This gap is preset at the factory on new units at time of assembly. A gap setting of .040” to
.050” must be maintained at all times. The opening gap must be checked regularly and reset when required. To inspect for proper opening gap:
a)Position the crankshaft at top dead center. Use die safety blocks or otherwise secure to hold the ram in this position.
b)Turn electrical power off to main control panel.
c)Remove end cap (31) from timer by remov- ing the two socket head cap screws.
d)Mark the location of the fiber follower of the LS4 (42) breaker point with respect to the cam No. 5 (33A). This will prevent the need for several timer adjustments to locate the top stop position. See Figure 5.
e)To inspect LS1, refer to Figure 6 and remove the two socket head cap screws
(43)and mounting bridge
Loosen jam nuts (30).
Rotate cam adjusting knob (29) so that breaker point gap being measured is at its maximum opening.
h)Measure gap as indicated in Figure 6.
i)If gap must be adjusted, follow instruc- tions given in Paragraph 3.1.2.
j)Lubricate the cam follower with a multi- purpose lithium soap grease.
k)Measure gap of LS2 by repeating Steps to
