Good morning all!
I'm putting the finishing touches on my 1953 FLE motor and the last thing is the filter screen for the hydraulic lifters. I have the correct OEM cartridge-type screen assembly (24982-52 screen and body) but must order the 8856 check ball and 24992-52 spring, as well as the two 24990-52 bottom seals. However, according to the 1949 through 1957 parts book, the ball and spring was only used initially for a short time, early in 1952. Apparently they must have been used to prevent drain-off of the tappet feed circuit when the motor was off and proved to be ineffective and/or unnecessary. Given this, I'm considering not using these two parts. However, if I omit them, will the thickness of the bottom seals alone be enough to hold the cartridge-type filter body in-place?
Also, can I substitute one of the later exposed screens (24975-63 or 24981-66) and associated surrounding springs (24979-63 or 24982-66) in lieu of the earlier cartridge assembly? I don't have another right side panhead hydraulic motor case, so I can't compare the machined depth of the filter well, but if it's the same depth, I would think that the -63 parts should work (using the two base seals), as the cap bolt was the same up until, and including 1965 and was changed for the shovel motor. When I used to do this for a living I barely remember seeing the closed cartridge bodies and commonly used the exposed screens, so I seem to remember that they are interchangeable - but my memory is what it is....
Thanks
