Thread: Noisy clutch/gearbox

This is the noise it's making (at the end of the clip). It happens just as you let the clutch out.

YouTube

So it means a whole lotta work for a $5 - $10 part! Put a new one in when I did the clutch. Grrr.

Did you leave it dipped in oil overnight? The brass spigot bush i mean? Not sure why the comment on YouTube says spigot bush though. I don’t see how it would make that noise. Sounds more like gears grinding.

Yes, I think that you will find the noise IS gears grinding, simply because the primary shaft is still turning / dragging around because of a failed or dry spigot bush. The clutch will release but the shaft is still turning slowly.

Yes, working on getting the old bush out now - it is shot to pieces . Have to carefully use a centre punch and chisel to split it to get it out. I tried an internal puller with a good size slide hammer a few times, but it just laughed at me. I'm not laughing back though my sense of humour just doesn't go that far .

Cheers,
Tom.

I think I left it in oil, but I can't remember for sure. It did receive a good covering with a quality HP oil as well. But it is certainly shot. Still working on getting it out.

Cheers,

I remember you posting a few months ago when you last had the engine out to do the clutch. Like the old saying goes: "if it wasn't for bad luck, we wouldn't be having ANY".

Years since I did anything with clutches, but it is a good idea to scrape a small chamfer on the inside of the bush after you have fitted it into the flywheel. More so if you do not have the correct splined alignment tool when installing the clutch. And of course it goes without saying that the shaft itself has no score marks etc. on the spigot. Cheers.

Yep, i put a small chamfer on the bush. I also used an alignment tool - although it wasn't the best, but it certainly had it close!

Sometimes you can fill it with grease and then put rod or punch of same size as hole in it and give it some wacks with hammer and it comes out. Didn’t work for me. Ended up using chisel and hammer and slowly chipping away at it until it split.
