clutch trouble

Hello all

68 Bay Bus

Out and about, pressed the clutch pedal. snap, crunch, grind,... loud n orrid !!!!

Clutch pedal went slack. So I guessed the cable. Pressed the pedal, crunch grind loud orrid ! - not cable, next guess - trow out/release bearing.

I stopped and thought of a way to get home, without too many stop lights etc and managed to drive the 30 miles home holding the clutch pedal UP with my foot and changing gears, clutchless .

So. I pulled the engine, and bits of bearing and springs fell out of the bell housing all over the floor. So I thought my second guess was right

- wrong !!

I noticed that what was left of the bearing wasnt centered on the input shaft. A closer look showed the throw out shaft with the forks on that holds the release bearing had slipped to the left about an inch. the spring had come off the bottom stop - loose pedal - So I guessed that the pin/locking bolt that locks the bushing had come loose.

Next I bought a bushing repair kit and replaced the bushing and seals on the left side. The bushing on the right seemed ok.

Just got it all back together, putting the new return spring on and the whole lot shifted left again. The circlip had popped out of the groove and wouldnt go back, the groove had become rounded.

So went and got a new throw out shaft and the right side that fits in the right hand bushing is bigger !! ARRGGGG wont fit. The bushing from the kit fits the shaft but I dont know how to go about getting the old one out !

So after all that ... How do you get it out ? (the bushing ! ) It looks like brass I hope to get it all back together in the morning, so any ideas will be appreciated !

What a Day !!

TIA

Is it possible that the shaft you got is the later style? Is the fork same or different?

Anyway, the bushing can be threaded and a bolt screwed in to pull it out. Or....drill a couple of tiny holes from the *outside* and press it out with a drift pin.

But first, check that the OD of the new bushing is the same as the old or you'll have another problem...

It looks different, but the same ! The forks on the old one are big and beefy and have a hole for te clip and a semicircle cut in for the bearing.

The new one, the forks are small and puny but are for the same type bearing.

The guy at the shop said he had not seen one like mine. but the new one should have been the same fit.

Good plan ! :-)

Or....drill a couple of tiny holes

not sure about that one !

I wondered that myself. from what I could tell the new one is smaller - I was hoping that there is a step inside the hole so it would fit.

I also thought I could try and get the other one out in a good enough shape to put it back !

Threading might work for this.

I had other ideas ...

I could turn the diam of the new shaft to fit the old bushing.

I could use my old shaft by ditching the circlip and drilling a hole for a split / cotter pin.

What do you think ?

I think I like the cotter pin idea best! :-)

Yes, it will weaken the shaft, but I don't think it will matter way out at the end.

I'm really suspicious about the new shaft; just doesn't pass the smell test...

In the shop there were about 5 or 6 different ones he brought out for that type of bearing. all except this one were not even close - like an inch short etc.

This one looked functionaly correct in all the critical places, just like a cheap after market copy though. The difference on the end is slight. It seems like I could tap it in with a hammer, sort of close ! But I know it then wouldnt budge !

I just had another idea as I am typing :-) ...

I can put a couple of tack / spot welds to the side of the circlip groove to stop it slipping to the right :-)

I think that would be the best idea. Amazing what you think of when you sleep on it .

Thanks for your input
