4. Knock-Off Eccentric (Late Style) - The redesigned trip
bail contains only one extension. It is adjusted to .003"
to .008" as shown on Fig. 34.
5. Trip Bail (Late Style) - Adjust so that the cycle clutch
trip bail is parallel to the armatures. The following
procedure may be used:
a. Disconnect the trip link.
b. Loosen screw (Fig. 34.4).
FIGURE 34.4 Trip Bail
c. Apply slight pressure to the knock-off extension
(Fig. 34.1).
d. Appl y sl ight pressure to the T -2 and R-5 armatures
(Fig. 34.1). Both armatures should be touching the
tri p ,ba i I. If not, form the I eft tri p ba i I support to
obtain this condition.
e. Tighten screw in Fig. 34.4.

Magnet Unit (Fig. 32) - Position under its two mounting
screws for .005" to .0lO" clearance between the pusher
tai Is and the armature latching surfaces (armatures at
rest) •
Mounting Bra.cket (Fig. 34.5) - Position under its four
mounting screws .009" to .018" clearance between the
pusher tails and armatures.
8. Trip Link (Late Style) - The clevis is now attached to
the link and the adjustment is made with a self-locking
nut. The ad justment is the same as in Fig. 37.

Insufficient "bite" could cause extra cycles since the
trip lever may slip off the latch lever.
Excessive "bite
ll
may cause failure to cycle since there
is a limited amount of motion available from the arma-
tures to pull the latch lever down.
Mounting Bracket (Unit Installed) (Fig. 35) - Position
front to rear so that the trip lever clears the cycle clutch
latch by .003
