Gearbox cluster bearing track.

[Ihateyoubutler]

Anyone know where I can get the gearbox cluster bottom bearing surface machined and a track fitted? (As in Sticky's book).It's pretty corroded, but does it really matter anyway?
Don't know really if it's worth the cost or just wait to see if I can find one.
(Italian gp 125 if anyone has one for sale?)
Thanks.

I bought one from Jem's stall at last wicksteed.

Thanks for the replies.Don't think I've explained it properly.It's the bearing surface on the cluster itself which is shot.This needs machining down and a new track (same size as origonal bearing surface) fitting on (like a mag side crank bearing).
Thanks.

Think MB do that. Also think they sell the part so you could get local engineer to machine Xmas tree and fit.

don't you just machine the cluster and fit a thicker track in the casings to match?
GP 125 is the same as gp200 anyway so probably easier to simply get new cluster? Its that time v. money thing all over again

Lambretta used a tool for removing the track. Which a similar item was available from MachineMart about ten years ago, not sure if the still sell it.
But if you get a bar machined to the diameter of the track so it's a tight slide fit, heat the case by the track then just over half fill the bearing track with high melting point grease, place the piece of steel in the hole center it up & give it a sharp tap the track should rise out of it's seating slightly because of the pressure.
Otherwise dremmel through one side carefully then pull out.

I think thats exactly what I need, thanks. The link doesn't work for me, but I'll ring them.
Sorry again about the poor explanation of what I needed, it's on page 56 of Stick'y book, bottom left of page (the cluster/xmas tree itself).
Thanks again for all the replies.
