Oddly have seen a rise in badly fitted crankshaft spigot bushes on manual engines, if not completely flush with the crank face the gearbox input shaft batters the bush to the point it starts to break up, as you can see in the photo's the bush wear/ damage can lead to gearbox input shaft excessive movement which potentially can lead to noisy operation, vibration and at worse clutch or even gearbox damage, ignore the oily mess of the engine in the pics, was duff anyhow.

 

Mad this part which cost just a couple of pounds can cause so many issues if not fitted correctly, just a heads up for you.

Any common factors in emerging damage ? Like who did the conversion ??????

That second to last pic is just what i needed to see the gearbox to block brackets. Cheers Jeff

Could it be the case that somebody has previously been trying to get the bush out with a chisel and gave up?

Oooo was this my dead engine by any chance?

Yup!

Another important and overlooked item and cause of messed up (spigot) bearings and clutches is a missing lower/2nd metal plate between the bellhousing and the engine. (found on Zeds with manual transmissions only.)

 

The 2nd plate is there for a reason and NEEDS to be used...

Is this like a thin shimmy type plate that goes all the way round between the gearbox and the engine?

I don't remember seeing a 2nd metal plate.

Please clarify for me, I'm confused.

>> Is this like a thin shimmy type plate that goes all the way round between the gearbox and the engine?

 

there should be 2 plates: the one that goes all the way round is the main plate and a second one, basically a halfmoon shaped one, that sits over the lower part.

It often gets lost and/or forgotten after the gearbox is removed/refitted for whatever reason.

Paul's car was a manual when he bought it
