Lovely job i will have a look in the morning then and can have a crack at it sunday night as i found a rather handy metal bar in the garage that i can use to lock the primary gear with.

Yep...wont be easy to get that bolt off now! also the inside face of the transfer housing where the bearing has commited suicide looks worn. you may need to get it machined flat again and a new set of oversized washers to take up the idler gear end float...check the gearbox case behind the idler gear..If it looks like this...it will need a bit of work...this one did!!

Also Andy i cant see where you are on about? I had another look in person aswell. Do you mean the housing that the wrecked bearing is in or the one below that has chips around the edge(can just see in the photo) Wrecked bearing seems very snug, couldnt even get it out earlier so have given up till later

You have to put the casing in the oven , wait until the wife is out ha ha ha at 200 for 10/15 min then slam it down on a flat wood surface and it should fall out you will not get the outer case of the bearing out unless you do this and refitting the new one is the same you are a cheff bake it

Haha are you serious? i take it it expands so you can get the bearing casing in?

Cheers for the tips

Yes gospel it is the only way

Or what you can do is weld a nut on top of the bearing, and then turn bolt through with a couple of washers and this will pull the bearing out of the case!

Hi Bud isn't there a fear of the outer race pulling off centre and the bolt pucturing the casing and also weld splatter

[liirge]

well, if you are careful and make sure that you put spreaders on the aluminium casing there wont be a problem.

Done it loads of times never had a problem, Even a really **** weld and **** alignment usually pulls them out.

Can't see an issue with splatter, and if you do manage it just remove the splatter.




See what I mean....really not straight in anyway, I think i used lots of little nuts as spreaders kept putting more down and then tightening a couple of turns then more nuts then another couple of turns. Don't really know why I did it in such a bad way that time, just did! haha

Only one problem i cant weld well i can spot weld but i see your point , i got the slam dunk method of a gearbox site and said it was easy
i get your point though

Gday mate,

Cant be bothered reading the whole thread as i am to tired it almost 2 am over here. The photo is of the crankcase ventilation. Not sure if anybody as mentioned it already.

Anyways have a read through this. It was written by one of australias premier mini specialists and has alot of good info on how to make a small bore quick. He mainly covers the 1098 but they are basically the same as a 998 apart from crank.
