Transfer gear case bearings??
Turbo Mini Forums

looking on the mini sites and there is so many bearings to choose from, which one do i need for the bearing on the end of the 1st motion shaft that goes into the gear casing and also for the idler gear??

Cheers Rick

Nose bearing (replace the outer race in the transfer case aswell, try not to mix and match):

Idler bearing depends if its a/a+

A series:

A+:

You need 2 of the idler bearings, one for the gearbox side, one for the transfer case. You can get another bearing which lets you use a series gears with a+ casing (IIRC). Going to hazard a guess and say it wont be a 3 syncro box?

theres 3 different bearings, two of them are the same

the two bearings that fit into the bell housing are the same and then you need two different ones.

I bought the following:

2x

Thats what I bougth to replace ALL of the bearings related to the drop gears (both the idler and 1st motion shaft gears, as well as the bellhousing casing bearings)

EDIT: Mines A+ If yours isnt you just get the smaller idler gear bearing iirc

Mine is the A+, thank you guys for clearing that up. i think ill wait untill minispares have all the bearings in stock before i order. thanks again

Oh dear =[ well I'll see how well they fit into my engine and if they arn't perfect will send them back

Just destroyed the brand new un opened idler bearing I put to one side from Minisport. Not only does the packaging have the part number for the Torrington bearing, but the outer race running surface has noticable etching in it, meaning it is trash before it's even been anywhere near a gearbox! This is something you would NEVER be able to see before you installed it, without having to destroy the cage.

The rollers running faces themselves are only a little shorter than the Torrington in the region of 0.5mm shorter. BUT, the smaller layshaft bearing (the one at 1st geear end), the cage has a much more 'closed' design (reducing oil flow in nd out?) and the rollers are roughly 1mm shorter. The larger layshaft bearing looks to be identical to a genuine bearing. The third motion shaft double roller bearing has absolutlely no markings on it what so ever, where the genuine bearings are manufactured by RHP. The diff bearings are made in Japan jobbies, But IIRC the first motion shaft bearing was infat a RHP bearing anyway.

The bearings are probibly OK for a moderate engine, but anything with decent torque, I would be skeptical about their abilities.

I posted a topic in the FAQ/ Knowledge section that discusses this, with documentation showing pictures of types of failures.

Hello all I had my bearings turn up during the week and the first motion bearing that goes into the transfer casing is too small. I think I have a genuine turbo transfer casing and the bearing are no longer available right?

What shall I doo?

Genuine turbo ones are still available.
