IBM Selectric Reference Manual

Insufficient clearance may cause extra cycles due tothe
cycle clutch latch bouncing off the trip lever.

Trip Link Clevis (Fig. 35) - With either the T2 or R5
armature manually attracted, adjust the clevis so that
the latch lever overthrows the trip I,ever lug by .005"
to .020" (Fig. 37).

NOTE:
If necessory, refine the pivot eccentric adjustment to
obtain equal latch lever overthrow from the T2 and R5
armatures (Ref. Fig. 31).

INHIBITOR
1.
Adjust the inhibitor trip lever (Fig. 39) so that the bot-
tom edge of the inhibitor pawl is flush with the bottom
edge of the cycle clutch latch (Fig. 39) with all parts
at rest.
This adjustment provides an adequate "bite" between
the cycle clutch latch and inhibitor pawl to prevent
extra cyc I es.
