Rear drive small bearing

[xtzanos]

It seems i have a little proplem removing the (sorry about my english) little case of the small bearing or the rear drive. It is stucked at the rear drive housing. The manual says that it will drop off by oly heating the housing. I tried but it didnt even move (even when i tried with a screw driver).
any ideas? My bearing puller doesnt really fit in there.
Thanx

xtzanos, a picture would make it easier to decide which bearing you mean?

Do you mean the paralever bearings (item 2 in this picture)?

 

[xtzanos]

No i mean the smaller bearing of the 2 that support the crowngear. Sorry i cannot find a picture. It seems that the big bearing that usually fails is Ok. But the condition of the small one is really bad. I was lucky to find out before it ruined the crowngear

Ah, I understand - item 5 here:

Unfortunately I have never changed this bearing - hopefully someone will be able to advise.

Edit: You can find these parts pictures here:

Correct thanks. My problem is the housing of this one which is stucked at the rear drive housing.

I have searched advrider as well but no luck

You want to remove the bearing outer race from the final drive case -

heat the case up and you need an internal puller. Or with the case very hot a seal puller will be enough to get it out.

Thanks, i have already destroyed a puller so i 'll try with a better/expensive one

 

[xtzanos]

OK the bearing outer race has been removed with an internal puller.
Thanks everybody

As an aside, if anyone's trying to get a bearing race out of a blind hole like this and they don't have an internal puller, you can do it by trimming a piece of 5mm+ steel plate to fit into the outer race, drill a clearance hole in the middle of the plate, weld a nut onto the plate with its bolt running through the clearance hole, then weld the thing into the bearing race. Let the whole lot cool, heat up the casing and then you can jack the race out using the bolt.

Done this many times, usually using an m10 or m12 bolt, obviously depends on the bearing size.

Need a welding set of course

Need a welding set of course

And if you have one of those forget all the plates and nuts etc etc - just run a bead of weld around the inner bearing race. It'll jump out at you.

Would lots of swearing and cups of tea not accomplish the same thing?
