The guide for the rotate differential is attached
to the top of the di fferential mounting bracket by
two screws just
behind the balance lever. The
screws
are accessible from the rear with the motor
removed.
The tilt differential guide is attached to the bottom
of the differential mounting bracket and is easily
accessible from beneath the machine.
b. The latch bail guide should be adjusted left or
right so that all positive rotate and ti It selector
latches hang vertically in the latch bail. The
guide is attached to the lower left corner of the
differential mounting bracket (fig. 15).
14. Latch Bail Stop - The latch bail stop, located just beneath
the bai I, prevents the bail from getting beneath the selec-
tor latches during shipment. Adjust "the stop to clear the
latch bail by .005" to .015" when the bail is at the high
point of the cycle shaft cams (Fig. 16).

NOTE:
Excessive clearance wi II allow the bai I to over-
throw at the high point of the cams. During the over-
throw it is possible for the latches to get on top of and
bind off the bai I. This condition is more prevalent with
the check latch.

to .005" clearance between each latch interposer and
