type 9 bush
Who uses a bush in between the type 9 input shaft and flywheel?
I've been told without the bush the gearbox bearings wear out fast?
Can I get away without one?
Thanks

I presume that you mean a spigot bearing? If so, then yes, you need one - without it the shaft will be supported only at the gearbox end and all the
sideways forces will be transmitted to the gearbox front bearing and magnified by the leverage ratio.

I think you mean the bearing which is what Steve Walker was on about, you can get these from Burton power if it for a Zetec??

Yup a spigot bearing, it's for a rover k series with a pg1 flywheel and a v6 type 9 box

Hmm,
Not sure what size bearing you need for the K series, I'm sure someone will know.

Give an MG enthusiast garage a call, it's a relatively common conversion.
You'll need a bush and a bearing according to QED:

ps without isn't an option, as the clutch bites it will pull the shaft out of alignment and make a terrible noise as it increase wear
exponentially.

Ordered one,
I only ask this question as my fwd car doesn't use one so thought I may get away without one on the kit car

FWD drive gearboxes generally have the input shaft better supported inside the box - and if they had a spigot bearing on the input shaft it would make
them harder to remove the gearbox from the FWD car without also removing the engine
RWD boxes tend to use the spigot bearings to hold the front of the shaft in place - basically because the rest of the box can be made lighter /
cheaper this way
