Gearbox Bench Procedures
Prior to performing any bench procedure the pump and gearbox (unit) must be removed from the
apparatus as a single assembly. Use paragraph 5.8.2.1, General Pump Removal From The Appa-
ratus to remove the unit from the apparatus. These instructions also provide for gear oil removal,
to further prepare the gearbox for the performance of bench procedures.

isolate the gearbox before any bench procedure can be performed. Use the General Gearbox
Removal portion of paragraph 5.9.1 to separate the gearbox from the pump assemblies to iso-
late the gearbox as a separate assembly.
