5.9.2.1.1
Input Shaft Oil Seal (ONLY)
If the oil seal is the ONLY input shaft component requiring replacement perform this procedure to
replace ONLY the input shaft oil seal.
The oil seal for the input shaft is located on the drive side of the gearbox. The oil seal utilizes a
metal body that surrounds the seal. The oil seal must be replaced whenever the input shaft is
removed since the oil seal is Loctited in place (this prevents seal movement which would cause
an oil leak) and there is no way to remove the oil seal without damaging it. Therefore, the oil seal
is typically replaced as part of any input shaft or drive gear R&R procedure.
Replacing the input shaft oil seal without the removing the pump and gearbox is the preferred
method for this procedure however, this procedure typically requires gearbox removal prior to
performance due to limited access. If the pump and gearbox must be removed for access pur-
poses, see paragraph 5.8.2.1 for reference to the required Removal From The Apparatus proce-
dure. Refer to Table 42 for a list of tools and/or consumables required for this procedure.
