Clutch push rod question ?
Sesman:
I wonder if an old british dural push rod could be adapted to work🤔
Oddjob:
It's all about the diameter I'd imagine, it needs to be the exact same as the 500 or the seal won't seal.

Yours is a common problem with the seal cutting in to the rod, which will cause the oil to weep past the seal. Have loads of rods that look the same as yours .

Is it brain fade or did someone (Graham maybe) get some made as specials?

Similar thought from me. Seem to recall "silver" steel used, that's a ground to diameter stock heat treatable steel, and so suitable for something like this if bought in correct diameter. You could heat and quench the ends to harden after shaping them to correct radius.

There is a modern Honda which uses a push rod of the same diameter but it's slightly longer, I'm looking at using one of those when or should I say IF I can do an hydraulic clutch conversion, however it may be able to be adapted for use as a normal push rod. I'll take some measurements and see. It's also 3 parts, one long rod with 2 metal ends.

If you want a plain steel one you can use a 5 speed CB450 twin one but for some reason Honda lightened that part on the late 500K0's etc to a composite of alloy and steel combo.
