Hello everyone. Going into this project I couldn't find any good resources on how to approach identifying an old CAT pump so I could purchase service parts for it. This video talks about how to measure your unit to find equivalent modern model parts and discusses the fix vs. replace cost decision depending on the amount of wear/damage in the old pump. In this case I should've probably just ordered a new pump to start with, but live and learn, I suppose.
This video is primarily focused on the 2SF20ES, 2SF30 ES, etc... line of pumps, but the concepts would apply generally to any pressure wash pump rebuild. Thanks everyone for watching and hope this helpful.
