13.  Slide rotor-endplate assembly into the pump 

housing. 

 

Slide the cushion material used during 
disassembly under the rotor on the opposite end 
to gain leverage during assembly of endplate to 
housing. 

14.  Lift the rotor-endplate assembly 

and slide over the 3/8 inch 
threaded guides and install the 
endplate bolts. 

Tighten the bolts sufficiently to 
make contact between the endplate 
and the housing.

15.  Coat vanes with oil and install 

the vanes in the rotor. The 
vanes should slide freely in the 
vane slots.
