pletely disassembling the pump by removing the
impeller through the back cover opening and using
a pair of stiff wires with hooked ends to pull the seal
parts out of the seal plate.
Inspect the seal liner (76) for wear or grooves
which could cause leakage or damage to the seal
packing rings. The seal liner is a press fit in the seal
plate, and does not normally require replacement.
If replacement is necessary, see Seal Installation.
If no further disassembly is required, refer to Seal
Reassembly And Installation.
Separating Intermediate And Drive Assembly
From Engine
(Figure 4)
If it is necessary to separate the intermediate and
drive assemblies from the engine, support the in­
termediate using a hoist and sling, and remove the
hardware (6 and 7) securing the intermediate to
the engine bellhousing. Remove the intermediate
guards (35 and 36, Figure 3) and separate the as­
semblies by pulling the intermediate straight away
from the engine.
As the assemblies separate, the flexible portion of
the coupling assembly (3) will remain on the shaft.
To remove the coupling from the shaft, unscrew the
two allen head setscrews from the bushing (2).
Screw one of the setscrews into the puller hole on
the circumference of the bushing. As the coupling
and bushing separate, remove the bushing, and
slide the coupling off the shaft. Remove the shaft
key (41, Figure 3).
It is not necessary to remove the outer ring of the
coupling from the engine flywheel unless the cou­
pling must be replaced. To remove the ring, disen­
gage the hardware (4 and 5) securing it to the fly­
wheel.
Shaft and Bearing Removal and Disassembly
(Figure 3)
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‐
equipped shop by qualified personnel.
Remove the intermediate drain plug (46) and drain
the lubricant. Clean and reinstall the drain plug.
Disengage the capscrews (38) and remove the
bearing cap (40), gasket (37), outboard oil seal
(43), and wavy washer (44). Press the oil seal from
the bearing cap.
Place a block of wood against the impeller end of
the shaft (42), and tap the shaft and assembled
bearings from the intermediate. Press the inboard
oil seal (50) 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.
