Clutch push rod question ?

[McCabe-Thiele (Ted)]

One end of my clutch pushrod is corroded quite badly on the outer surface does this matter or must I replace it?

If its okay to use what is the best way to protect it from becoming worse?

Are they expensive Ted?

Could you clean it up then heat treat it to case harden. I wonder if hard chroming is possible?

You can clean the rust off Ted with no problem. The problem area is where the seal sits on the chrome part, any wear or scoring causes a leak.

DS show no longer available plus they are I believe made from three parts with the centre section being a tube.

The corrosion has just started to creep into the last but one section so getting closer to the seal area  I guess.

To conserve the corrosion part, you could stand that end in rust converter fluid to stabilise, then just coat it in marine grease when installed to stop further deterioration.

You have read my mind I've already  dipped it in Evaporust overnight then Blued the end for protection.

DSS have lots of matching rusty ones:

You should be able to get it hard chromed Ted, I had mine done as it was as skanky as that one you're holding. Came out great and was about 35 quid I think.

Someone on here had some carb connecting bars done that looked ace, might have been Ken but have a look Iit might be on his back after 30 years thread I think........

Difficult to chrome as the ends are steel but the middle ally as i remember, Honda did do a complete steel one but the clutch action was slow

[Oddjob]

It was me Roo, it cost me £23 at the time iirc, just had 2 done a few weeks ago for the princely sum of £152.

As Bryan says they are a composite rod so not suitable I’d say for hard chroming.

eek, thats dear isnt it?

There you go Ted, get after it with the 2000 grit

Found an aftermarket direct replacement on CSML.

CB500T pushrod (combined alloy and steel) is same as later 500 four pushrod.
Original 500K0 part was a 450 part and solid  steel .. as was fitted on my 3/71 500K0 but I got a later one from 'BJMCaferacer' on eBay after an argument with about him sending it in two pieces and he claimed I was talking bollox about it being a one piece push-rod, as the one he first sent me was in fact a broken one.

So many sellers believe its two piece
