NOTE: The wear ring in the intake adapter cannot be removed without being destroyed. Inspect the wear rings and impeller per instructions on Page 5 to determine if
replacement is required.
•
Make a witness mark on the intake adapter and volute body to indicate their
relationship to each other which will be referenced during reassembly.
•
Remove the sixteen (16) hex head screws attaching the intake adapter to the
volute body. The screws may be threaded into the four (4) jacking screw
holes in the adapter flange and tightened in a circular sequence to separate
the intake adapter from the pump volute body.
•
Pull the intake adapter off of the pump body volute. Remove and discard the
O-ring.
•
Remove the cotter pin, impeller locknut and washer from the end of the im-
peller shaft.

Disassembly - Remove Intake End of Pump
Intake Adapter, Impeller & Mechanical Seal Removal
1.
Remove the impeller. Tapping the impeller lightly with a soft hammer will help to
break it loose from the shaft. If necessary, the seven (7) 3/8-16 UNC tapped holes
through the impeller vanes may be used to attach a puller. If the seal spring retainer
remains attached to the back of the impeller, remove and discard.
2.
Remove the impeller key from the shaft.
3.
Remove the mechanical seal spring.
4.
Remove the mechanical seal bellows. First apply a light coating of oil to the mechanical
seal journal then grasp the seal bellows by hand and and try to remove with a combined
pulling and twisting motion. If this method fails, proceed with the steps on the next page
to remove the pump from the transmission. The seal bellows will be forced off the shaft
during this step.
