Gear lever shaft oil leak - best solution?
« on: 08.09. 2017 22:00 »
Hi all
My A10 weeps a little oil from the gear lever shaft. Not a huge amount, but enough to make me want to fix it. Has anyone fitted a seal of any kind? I'm happy to find my own solution, but I'd love to hear of anyone's experiences in fixing this.

I've ordered a Nova 5 speed 'box, so would like to   look to fix this when I fit it. (I like making mods 😁)

1961 A10 - somewhat modified :-)
1980 TZ350 - lunatic Classic Race machine
1967 T20 Suzuki - heavily modified Classic Racer
1967 T20 Suzuki - pretty standard road bike
2007 KTM 660 SMC - fast and furious supermoto
Triumph 675 Speed triple
Ossa 250 and yet another T20 racer in bits both being built up

You may have excessive clearance between the selector shaft and the bush.

It helps to fit a breather to the gearbox; this can stop leaks from the shaft bushes.

This one was machined to accept an O ring.

 So, t20- how'd you get on with that ? I'm searching for the photo that (I'm sure) Orabanda posted for the location of his breather behind the Kick 'quadrant' (~thirdrant *conf*)...

 I went to a bike shop and bought the little breather thing a while ago (they had to order it in, but better than paying unnecessary postage), and unexpectedly have the cover off now so now dealing with it...

 I can't remember from the rebuild, but found that mine has been done also- maybe I did it back in the first build  *dunno*, seems to need a ??mm x??mm 'O' ring  *conf2* -I'll be back on that... *beer*
