Gearbox spigot bearing, where does it go n what's it for

[hodge]

Hi guys

Can someone explain. This to me and maybe post I pic of how and where it's fitted. I've got a horrible feeling I havnt fitted 1 to my 6 speed when I did the conversion.

Think it's generally a little hoop that goes in the centre of the flywheel.

it looks like a polo mate it goes on here (stevos conversion)

I havnt fitted 1 then. So what does it do. And what's the consequences of not having 1.

It provides a support for the input shaft of the gearbox as it goes through the hole in the middle of the bearing. I would imagine without it the input shaft has more freedom to move around off centre and probably cause premature wear to its bearings and oil seals.

 

If it were mine id put one in before i used it again!!!!

I'm pulling the engine out in a few weeks anyway cos the cars going to the body shop for paint. I'll fit 1 then.

Cheers guys.

Good plan mate, too expensive a gearbox to take a chance with

Using it without an input shaft spigot bearing in the back of the crank WILL damage the gearbox, possibly very badly. A torque converter on an auto car just has a snout that sits snugly within the bare recess in the back of the crankshaft, as the TC is always turning at engine speed. A manual has to have the ability to have the input shaft stationary, or at a differing RPM to that of the crank, hence the bearing. The gear on the input shaft is only supported by a single bearing inside the gearbox without the spigot bearing in the crank, the bearing in the `box will be damaged, as well as the gear and it's mating pair as it all wobbles about. The loadings will be awesome! Needs immediate attention, do not use!!!
