6.4 Install Input Housing and Set the Axial Endplay.
6.4.1
Press the seal into the input housing. Press until flush with the machined face.
6.4.2
Make sure the output housing (y-side) is face down on a flat surface.
6.4.3
Install bearing spacer / oil baffle:
6.4.4
Install the Shims.
6.4.5
Install the input bellhousing without use of sealant.
NOTE: Align notch near the seal with oil ports on the input housing.
NOTE: The bolt pattern should only permit this to be installed in one orientation.
6.4.6
Tighten bolts with washers. Applying final torque is not required during this step.
6.4.7
Install the shaft end retaining cap as a temporary fixture.
6.4.8
Lay wooden blocks inside the housing as shown in the picture below.
6.4.9
Install a dial indicator with the base on the inside of the housing and the tip on the
top of the shaft.
6.4.10
Using pry bars, with one on either side, lift and lower the shaft to determine the
endplay.
6.4.11
The endplay should be within the following criteria: between 0.012-0.020 in [0.3-
0.5mm].
6.4.12
If the measured endplay is within the recorded specification, skip to step 6.16. If not,
proceed to the next step.
6.4.13
Remove the input bellhousing.
6.4.14
Remove or add shims, as necessary.

Remove the input bellhousing.
6.4.17
Apply Loctite 518 between and around each hole on the input housing.
6.4.18
Install the input bellhousing with bolts and washers and torque bolts.
6.4.19
Follow Table in back of manual for proper torque.
6.4.20
Repeat endplay measurement as prior. The endplay should be within specification as
the thickness of the sealant is the only difference. If not within endplay, repeat steps
in this section from the beginning, but with sealant.
