its oh so easy even when using a spare input shaft to allow some droop
Do you tighten the pressure plate uniformly all around a few turns at a time to keep the friction plate in its correct place and not under tension on the input shaft

So just dropped the type 5 gearbox again and sure enough, the spigot bearing has come off the end off the crank and is loose on the gearbox input shaft. This is twice in a year. Two different brands but new spigot bearings. Both tapped home with a socket.

Last year the flywheel was lightened. But nothing was subsequently balanced. The current engine, whilst strong and reliable, feels coarse, probably even more so since the flywheel has been lightened. The bgh gearbox has had little use, albeit I’m a hamfisted idjut, but had replacement bearings throughout last spring. I did 4 events, no real driving otherwise. :?:

..and that’s probably why you’re killing gearboxes.

And rattling the bearing loose.

Ok. Makes sense. Something for later in the year me thinks. Not going to dismantle everything just yet

Why not try having a phosphor bronze bush machined as suggested by another poster. then Loctite bearing seal the outer to the flywheel.

Hi will, Must have missed that post re bush. Also Do you mean loctite the bearing outer face to the crank, not flywheel

I'm afraid you will have upset the engine balance by lightening the flywheel.

..and probably lost power as a result. Energy that would be used turning the crank is now being used up making the vibration.

I agree with all the above comments..but.. your gbox destruction issues predate that, don’t they??

Agreed with all the above but yes, as James pointed out, at least two spigot bearings physically failed big time before the crank was lightened, (only a year or two ago). Now they just fall out before falling apart :roll:

might be time to measure the hole in the crank where the spiggot bearing lives accurately , and compare with a known good crank

have not heard of this problem before but one thought, do you put grease in the bearing after fitting it to the flywheel? This should be dry otherwise the grease forms a seal and fitting the gearbox will hydraulically force the bearing out of the crank and along the shaft.
Probably not the fault but who knows with such a strange problem.

Hi All,

dropped the gear box, checked everything, new spigot bearing, different make this time and refitted. And I made sure she eased in.

So the result is....sounds like a bucket of nails when driving along

heh hoh.
