Needle roller in the bevel box

[mjseymo]

Dear All,

 

I've got a first series V11 and there is a bit of play in the needle roller bearing in the bevel box. How easy is it to replace this? Can anyone give me some directions just in case there's something in paricular I should know?

Thanks in advance,

Can be a pig to remove that bearing... still makes me shudder when i see a cold chisel..

Assuming we're talking about the deep inside bearing that cover the small right side seal, the heat method works well, just much higher temperature than I would have thought.

 

Once mjseymo confirms which bearing, I'll dig up the links I used to R/R mine recently.

Martin, (great name that), you might find the links below helpful if you mean the needle roller in the RH side of the bevel box. If so, you should be aware that the inner race length is important, as it is part of the axle spacer stack.

Thanks for the replies there's useful links there. I'm presuming (which I guess is dangeours) that it's the outer needle roller near the swingarm. Here's a dropbox link to a 10 sec vdeo

The bike when I got was in a poor state so the wheel bearings, spacer, axle have all been replaced along with the the bevel box inner and outer race of that same bearing (which were very rusty) once already along with a seal etc. This was done by an exceelant guuzi mechanic who unfortunatleyi for me is now living and working in Italy.  I may end up having to give it to a someone who really knows about the intacaices of this weird science of bevel boxes......

When I've had them really rusty and seized I have welded a washer in the outer race, then you can drift it out easily as the heat from the weld frees it, you can't get a drift on the race without the washer welded in

[MartyNZ]

After looking at your video, I wonder if the washer or inner race was left out during the last tyre change. It should not move that much.

See the parts breakdown item 31 & 33 shown here: https://www.v11lemans.com/forums/index.php?showtopic=20168&page=3&do=findComment&comment=226883

If those parts are missing then you have found your problem.

[mjseymo]

Good thought but 31 and 33 are definitely present I'm afraid!

Perhaps the inner bearing, #12, is the matter?

[mjseymo]

Going to replace the outer one to begin with. Who would you recommend as the best quality bearing manufacturer?
