Simpson AAA Water Shotgun pump rebuild

Machine Repairs
1

I already have a pressure washer but was given a Simpson Pressure Washer Model WS 3035 SRA with a Wisconsin/Robin motor. It starts right up but there is water leaking into the pump housing. I started it but owner told me it leaked and there is milky oil in the housing. So a pump rebuild is needed but I am not finding any parts online nor any part diagrams. Of course I’ll take it apart before ordering to check for internal damage.

Pump model HP3530B-S

Can someone point me where to source the parts or is it not cost effective because of the age?

Direct or belt driven?
Have you tried contacting Simpson company? They may be able to help with identifying the actual pump brand and model or with parts.
