Place cover (6) in assembly position
with power divider cover (12) as
shown. Hold cover in position by hand
and measure clearance between the
covers using a feeler gage. The
measured clearance plus 0.005 in.
(0.13 mm) equals the thickness of the
initial shim pack.
NOTE
To ensure proper output shaft end play,
necessary shimming of cover (6) must
be calculated and checked. To do this,
carry out step 8 thru 10. Repeat these
steps as necessary until correct end play
is obtained.

Install bearing cover (6) with a shim
pack of calculated thickness. Fasten
cover (6) to cover (12) using four
capscrews

and
lockwashers
installed around shaft (9). Tighten
capscrews to 125 ft lb (170 Nm).
Install yoke (5), washer (4), and nut
(3). Tighten nut snugly.

shaft end play as shown. End play
should be in the range of 0.003 to
0.007
in.
(0.08
to
0.18
mm).
Calculate shim thickness to be added
to or deleted from the installed shim
pack (7).
(10) Remove yoke (5) and cover (6).
Adjust shim pack as required by
calculation in previous step. Install
cover and yoke, and recheck end play.
