My son and I have bought a Defender 90 as a doer-upper and have found a 'yikes' issue. He says its a missing spiggot bearing (forgotten by previous owner) I havent a clue. Hoorid rattling from where the spiggot bearing lives when engine idels and clutch pedal UP. Depress clutch pedal, noise stops.

Any thoughts from that scarce info?

With out the spigot bearing [ which is just a plain bush] in place the input shaft to box and clutch plate would tend to move about some, this would be when clutch is in. Result is likely the gearbox input shaft bearing wearing over time making noise or plate itself getting loose on the shaft I recon. When pedal down shaft stops turning so no noise. Load when driving likely reduces noise.

Did he say "forgotten by previous owner" or was that just a guess. More likely the clutch release bearing I recon.

Bronze spigot bearing (in the very center of the flywheel) ..
The gearbox input shaft sits in it,

Yes the flywheel is pants, yes I had it skimmed (-17mm) before it was refitted.

-17mm !!! That was radical.

this new fangled metric system is awfully confusing especially when people still use old fashioned measurements as well.

I have lightened a few flywheels but not like that. 0.017" looks better

He did say that as a guess because he knew there’d been a rebuild.
He’s gone through everything now other than this bearing to get the mot so that’s next I guess if the noise persists. We shall see. The vehicle will be sold though as that was always its point. But not sold in a dodgy way.
