Hello,

I recently bought a 1952 F263 Fireball that sat for two years outside uncovered.
As i want to replace my current hydraulic lifters on my Super, i am going to take those coming from that motor.
Unfortunately, i found some surface rust at the bottom of lifters cylinders and some have a little deformation or are scratched a little bit.

I started to brush the rust and result is not so bad but scratches are still there.

Can i use them as they come? do i have to get them rectified?
Did they received a special thermal treatment at the bottom (in french sorry - don't know the US term, trempage ou cementation)?
Is there a risk with the camshaft if i use them?
TIA

hi!
i think new lifters would be a very good idea!.to take bad lifters from one engine and putt in another would realy wear down the camshaft.

Lifters can be "rebuilt". To rebuild a lifter, it must be disassembled and cleaned, it should be tested for "leak down" and the bottom must be resurfaced. You can probably get away with dissembling them yourself and cleaning them up, but a rebuilder will probably do it for you. Phone a cam grinder, he will probably do lifters too. You must resurface the lifter or the cam will be doomed. Lifters must always stay matched to the lobe they were installed on! When the lifter is ground it is convex about .001" (NOT FLAT!) and as it rolls over the top of the cam lobe it turns a little bit.

I will certainly follow your advice Bob. As my lifter are in good conditions, i can have a good result once resurfaced.

I hope that my camshaft won't cause me any problem when the lifters will be reconditioned.

Thanks to all of you for the response.
Time to ride now.
