I have another one of those technical questions that I can't find an answer to. I'm doing a 48 FL oil pump and the check spring is way short of the 1 9/32" the book states is the approximate length for #26363-36 spring.
I have a bag of OEM springs labeled 2636-56 (1956-1965). These springs are all approximatly 1 9/32". I assume they were labled wrong before I got them.
I pulled the springs from 7 pumps varying from 1948 to 1965 and they were all the same 1 9/32" with .0215" wire except for the 51 spring has .0205 wire.
My question is what is the length of the 26363-56 spring (info not listed in any of my HD manuels).
