Removal - G Series
1. Position a supporting device, such as a jack, under the gearbox.
Note: The number of screws that secure the rear bearing housing to the gearbox depends
on the model, e.g., the short gearbox uses seven (7) screws; the long gearbox uses eight (8).
2. Remove the 7/16”-14 screws securing the rear bearing housing to the lower gear-
box housing.
3. Remove the gearbox from the apparatus. Move the assembly to a clean work
area and clamp into a suitable and stable holding device.
4. Place a temporary cover over the exposed pump assembly to prevent dirt and
debris contamination.
5. Inspect bearings and internal parts for signs of excessive wear, pitting or damage.
Repair and/or replace accordingly. For gearbox disassembly, see “Disassembly,”
on page 149.
