Ossa 250 MAR clutch pushrods

[ColinPybus]

Hello there, Can anybody tell me the correct diameter and length of these rods and why does it have to be in two pieces?

I don't have a motor apart to measure but there are two pushrods to minimise clutch drag (the ball between the two rods means that the actuator end push rod doesn't spin while the clutch is disengaged)

Ok cheers for that, I didn't realise there was a ball between the rods. I can't remember seeing one when I stripped it. I'll have a closer look at the drawing I have. Rods are about 112mm long and a non standard English or metric size. I think they were 0.225" in diameter. I was thinking of using  through hardened 6mm diameter pins (0.236") that will fit easily and now I know, a 6mn ball bearing. Thanks again.

From memory, ( could be wrong)

Correct diameter of clutch rod is important to prevent oil leaks (where it comes out of sprocket?)

It's a while since I looked at mine, but seem to remember this happening , and the problem was a slightly smaller rod than original had been fitted previously

Thanks for that, I'll size the seal at the sprocket end and go from there.
