To prevent damage during removal, it is
recommended that bearings be cleaned
and inspected in place. It is strongly rec­
ommended that the bearings be replaced
any time the gearbox is disassembled.
Clean and inspect the bearings (20 and 27) as out­
lined in Cleaning and Inspecting Bearings. If the
bearings require replacement, use a suitable puller
to remove them from the drive gear. Remove the re­
taining ring (18), and spacer (19) from the drive
gear.
If replacement is required, use a suitable puller to
remove the bearing (21) from the gearbox housing.
Idler Shaft Disassembly
Position the gearbox housing on a solid surface
with the bearing cap (33) facing up. Support the
housing on wooden blocks while in this position.
Disengage the capscrews (32) and remove the
bearing cap and gasket (40). There is a tapped
hole (3/4-10 UNC by 5/8 inch deep) in the end of
the idler shaft (35) to accommodate a specially‐de­
signed puller (G‐R P/N 48781-007). Use this tool
to pull the shaft and key (36) through the idler gear
(37), and remove the idler gear through the top of
the gearbox.
To prevent damage during removal, it is
recommended that bearings be cleaned
and inspected in place. It is strongly rec­
ommended that the bearings be replaced
any time the gearbox is disassembled.
Separate the outer race of the front roller bearing
(34) from the inner race. Slide the inner race of the
roller bearing (43) out of the outer race.
Clean and inspect the inner and outer bearing
races as outlined in Cleaning and Inspecting
Bearings. If bearing replacement is required, pull
the inner race of the front bearing (34) off the shaft.
Pull the outer race of the roller bearing (43) from the
gearbox cavity using a suitable puller.
Impeller Shaft Disassembly
With the pump end disassembled (see PUMP
AND SEAL DISASSEMBLY) and idler shaft re­
moved, the impeller shaft (39) and bearings (38
and 42) can be pressed out from either side of the
gearbox.
To prevent damage during removal, it is
recommended that bearings be cleaned
and inspected in place. It is strongly rec­
ommended that the bearings be replaced
any time the gearbox is disassembled.
Clean and inspect the bearings as outlined in
Cleaning and Inspecting Bearings. If the bear­
ings require replacement, use a suitable puller to
remove them from the shaft.
Cleaning and Inspecting Bearings
It is recommended that bearings be cleaned and
inspect in place as follows.
To prevent damage during removal from
shaft, it is recommended that bearings be
cleaned and inspected in place. It is
strongly recommended that the bearings
be replaced any time the gearbox is disas­
sembled.
Clean the gearbox housing, shafts and all compo­
nent parts (except the bearings) with a soft cloth
soaked in cleaning solvent. Inspect the parts for
wear or damage and replace as necessary.
Most cleaning solvents are toxic and
flammable. Use them only in a well ven­
tilated area free from excessive heat,
