Same here. I really wish I had even a fraction of your skill with cars

Bump from pits of hell

I should have done this when I built the engine but the clutch is on its last legs and shuddering the car to hell when I pull away. There are 3 things that can cause this and I plan to remedy all of them because I don't want to have to pull the engine out again once I'm done.

First is a warped or worn friction plate. That's the disc bit here with the springs in the middle:

I can get a new one of them and I'm going to replace it. Second is a warped or worn pressure plate. That's the spring loaded cover that goes over the friction plate and again I can get a new one so I'll replace it.

Third potential problem area is the surface on the flywheel and I can get it refaced to make sure it's flat. Since it's on the lathe it would be rude not to get rid of a bit of excess material wouldn't it? I got my friend to shave my spare down a bit:

So the clutch mounting face and the back face were trued up by the same amount so the clutch depth remains the same. I got him to machine down the ring round the outside that locates the clutch and the ring-gear so it's just a minimal lip to locate the clutch and a chamfered step to hold the ring-gear. Then on the back face I got him to machine a few millimetres off the surface all over and chamfer the squared-off back edge right down:

That's a lot less weight on the outside edge so it should spin up a lot faster with no loss of strength. It's not as light as an aluminium flywheel but it was only £20 compared to £200! All I know is it's over 2.5Kg because the scales for weighing the mail can't take it

RIP engine - it expired last night in a spectacular ball of smoke

Oops, any idea what caused it? Something you did or just bad luck?

Jonny69 · 28-02-2008, 16:26

Yes it was something I did. I ragged it hard every day for 5000 miles and it couldn't take it

lostkat · 28-02-2008, 18:40

Oh no

I hope you're going to replace it???????

Darrin · 28-02-2008, 19:16

Any chance of using parts from it and getting your spare block operational?

Would be an utter shame for all that work to have gone to waste.
