I just use a press to push the rocker shaft out of these old FS-40 or FS-61. The same rod is used in FS-40, FS-40S, FS-48S, and FS-52S. The only difference between the wrist pins of the original FS-40 and FS-40S is the length, the brass pads had a thinner head so the newer wrist pin with plastic pads is a bit shorter. With enough heat the wrist pin will usually come out. I've serviced many that were tough to remove, but only gave up and cut one rod.
Enough heat (350° oven) will usually get the cam bearing out, but I made a puller. It should be noted that they rarely need to be replaced because they almost never corrode being made of stainless steel.

Then left to cure in a hot attic.
I probably would have kept trying had I not gotten a chance at a new first release fs-40 complete with rocker pin thru the head.
I'll still post a vid to this thread when she flies.
