Thank you for all the help gentlemen! I would have had to punt on this install without the help. Three things specifically helped me out...
1.
The mentioning of the set screws (the diagram in my
boxxer manual doesn't show them)
2.
Recommending a gear puller.
JonDon said the clutch would pull right off after taking set screws out. Also said NOT to use a gear puller. Nonsense.....no way was that clutch coming off without the $15 puller from harbor freight.
3.
Recommending hooking pressurized water directly to the pump. The pump wouldn't prime until I ran water through it with a garden hose. After that, she fired right up and ran like a champ!
A copy of my pump diagram....you can see that it shows where screws may be, but none shown in the exploded view......
