The input shaft utilizes two (2) double row angular contact roller ball bearings; one located on the
drive side and the other located on the pump side of the input shaft. Both of these bearings are
one-piece bearings installed in the gearbox housing. Using goo d practices; whenever a shaft
bearing requires replacing ALL bearings on that shaft should be replaced at the same time.
Since both bearings are an interference fit to the input shaft, it is impossible to R&R ONLY the
bearings. Therefore, perform the input shaft bench procedure (see paragraph 5.9.2.1 on
page 121) and reuse the existing input shaft.
5.9.2.1.3
Input Shaft Endcap (ONLY)
The endcap functions similar to a wheel bearing dust/grease cap. It keeps the lubricant in and
the dirt/dust/debris out. The endcaps are more efficient than cover plates and are installed us-
ing Loctite to prevent leaks or loosening from vibration.
This procedure may NOT require unit removal from the apparatus or gearbox removal prior to
performance (depending on the tools available). If removal is required, see paragraph 5.8.2.1
(on page 56) for reference to the required Removal From The Apparatus procedures. If gearbox
removal is required prior to bench procedure performance, see paragraph 5.9.1 (on page 118)
for reference to the required Removal portion of the Gearbox R&R procedures.
Refer to Table 43 for a list of tools and/or consumables required for this procedure.

Perform the following to remove and replace ONLY the input shaft endcap.
Input Shaft Endcap Removal
A. Remove input shaft endcap.
Drain any remaining gear oil from gearbox. 1.
a) Position oil safe catch container under drain plug.
b) Remove magnetic (and/or adjacent) drain plug.
i. Using 9/16-in wrench (or 8 pt. socket and ratchet – set for CCW), loosen mag-
netic drain plug. NOTE: If required using 10 mm hex socket and ratchet – set
for CCW, loosen adjacent drain plug.
