Separating Intermediate And Drive Assembly
From Engine
(Figure 3)
If it is necessary to separate the intermediate (10)
and drive assemblies from the engine, support the
intermediate using a hoist and sling, and remove
the hardware (1 and 2) securing the intermediate
to the engine bellhousing. Separate the assem-
blies by pulling the intermediate straight away from
the engine.
As the assemblies are separated, the drive pins (4)
will disengage from the drive arm assembly (6).
The drive arm assembly and the impeller shaft key
(5) are a tight press fit on the shaft (11), and will re-
main on the shaft.
It is not necessary to remove the drive plate assem-
bly (3) from the engine flywheel unless the drive
pins are bent or worn and must be replaced. To re-
move the drive plate assembly, disengage the
hardware (8 and 9) and remove the drive plate.
The drive pins are secured into the drive plate by a
tight press fit and peening. To remove the pins, drill
through from the peened end and drive the pins
out using a drift pin.
Use a bearing puller to remove the drive arm as-
sembly from the impeller shaft. Remove the shaft
key.
Inspect the dyna flex joints (7), and replace them if
worn. The dyna flex joints are a press fit in the drive
arm.
Shaft and Bearing Removal and Disassembly
(Figure 2)
When the pump is properly operated and main-
tained, the bearing housing should not require dis-
assembly. Disassemble the shaft and bearings
only when there is evidence of wear or damage.
Shaft and bearing disassembly in the field
is not recommended. These operations
should be performed only in a properly-e-
quipped shop by qualified personnel.
Remove the intermediate drain plug (44) and drain
the lubricant. Clean and reinstall the drain plug.
Disengage the capscrews (37) and remove the
bearing cap (38), gasket (36), outboard oil seal
(41), and wavy washer (42). Press the oil seal from
the bearing cap.
Place a block of wood against the impeller end of
the shaft (40), and tap the shaft and assembled
bearings from the intermediate. Press the inboard
oil seal (48) from the intermediate.
After removing the shaft and bearings, clean and
inspect the bearings in place as follows.
To prevent damage during removal from
the shaft, it is recommended that bearings
be cleaned and inspected in place. It is
strongly recommended that the bearings
be replaced any time the shaft and bear-
ings are removed.
Clean the intermediate, shaft and all component
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,
sparks, and flame. read and follow all
precautions printed on solvent contain-
ers.
Clean the bearings thoroughly in fresh cleaning
solvent. Dry the bearings with filtered compressed
air and coat with light oil.
