Good incentive to tidy the workshop!

..just found some CB350 ones which is much shorter and makes me realise the other one is a CB500 one. It is in three sections, steel at either end with alloy in the middle. The outside part is threaded into the middle section.

As of this writing, CB500 clutch push rods are pretty much impossible to find anywhere. They come up on Ebay every now and then but sell for $50+. That's just stupid for something that may well break again...
So, between Shifter19 and Number13 (seeing a theme here?):
Measurements for a Honda OEM pushrod are:
10 1/8 inches or 257 mm long
3/8 inch in diameter or 9.5 mm
You can easily fashion a push rod from
3/8" steel rod found at any hardware store.
The shifter side end should be ground flat and square,
and the brake side end should be neatly rounded in a semi-sphere
to mate with the clutch basket. If you err, err on the side of a bit too
long since this will allow you to keep the lifter mechanism low and avoid cracking.
May also be a good idea to quench harden the ends.

thanks for this info,just found my pushrod is snapped,so ordered a length of 3/8 silver steel,
Trigger:
John, i have had a batch of pushrods made by a tool firm. I found a NOS one to take the blueprint from and had them made to the measurements in silver steel with hardened ends. If anyone require one i will sell at cost price to members.
John, the CB500 push rod is not 9.5mm. when i bought the NOS one i was still not sure that i had the right rod, so i got Oddjob to send me one to confirm the right size.
