Reassembly Procedure
Observe the precautions given below and reassemble the unit in the reverse order of disas-
sembly.
Note:
The packings must be replaced with a new part. If any part is worn or damaged, make
sure to replace it with a new part.
Remove sand or debris from rubber parts (rear liner, impeller, pump casing, and suction
cover) before reassembling them.
After installing the impeller and the suction cover, make sure that the impeller rotates
smoothly and that it does not interfere with the suction cover.

Disassembly Procedure
Note:
Before disassembling, be sure to drain the oil.
(1) Removing the suction cover and the pump casing
Remove the hex bolts and the sealing washers from under the bottom plate and remove
the bottom plate from the pump unit. Then, use a wrench to remove the hex bolt with
flat washer to remove the stand, O-ring, suction cover, and the pump casing from the
pump unit.
(2) Removing the impeller
Using a box wrench, remove the hex cap nut, spring washer, and flat washer, to remove
the impeller, shaft sleeve, and the V-ring from the main shaft.
(3) Removing the rear liner
Remove the rear liner from the oil casing.
Note:
When replacing the check valve, be careful not to overtighten the hexagon nut. Doing so
may result in the decrease in its shutoff function.
