Re: Gearbox Shims
Fitted the old bearing (which didn't sound or feel any different to the new one) pulled the shaft in, 2mm shim , 6 thou clearance. Looking at the bearings side by side there was nothing that really stood out as different. Once again thanks for your replies

Re: Gearbox Shims
The bearing does appear to protrude into the casing, the gears sit below the shaft, the oilseal hasn't snagged, I've now done this 5 times with the same result, bearing out tomorrow I think. If there are rogue bearings about you could guarantee that I'd get one

I removed the layshaft and found a very thin complete o ring at the end of the shaft where the grooves start whether its been shaved of the new one or remains from the old one I don't know, either way I missed it twice going to have to start wearing my glasses. I'll...

Re: Gearbox Shims
Thanks for the replies, I fitted the shaft using a distance piece and the shaft appears to be hard up against the bearing, MB sell shims from 1.8 mm upwards and beedspeed sell half thickness shims, I've tried to measure the gap and it seems to be round about 1mm maybe smaller. I was just wondering i...

Gearbox Shims
Having replaced a damaged spanish casing with an indian one I'm struggling to shim the gearbox, with a standard 2mm shim the gearbox locks up when the endplate is tightened down. The layshaft is fully home, the loose gears are fitted correctly. If I leave the shim out it stays free. Is it common to ...

Drive side bearing
Hi Just fitted the drive side bearing, it went in very easy, too easy, there is an up and down movement, you can't push it out but it does move. There is no obvious damage to the casing. I tried the old bearing and that is the same, is the casing knackered or is there a solution to this. Its off a j...

Re: Casa lambretta 80cc Kit
Thanks for your reply Markus. The kit arrived and looks to be an exact replica of the vega barrel, I've just got to remember where the rest of the bits are then I can put it together

Casa lambretta 80cc Kit
Hi
Can any body tell me if this kit will fit on a 75cc casing, I know it was intended as an upgrade for the 50cc lui they are both 44mm stroke (I think) are the stud spacings the same. I did ask the people who sell them but they wern't sure
Thanks in advance
