So, my question to you guys is this, is there an alternative to the motorworks / BMW one, I`ve heard of twin lipped seals etc but don`t know the best one to get.

List of seals in this post 40 x23x6 I think..

Hello Hayden
I have the same issue as you. I changed leaking seal by the clutch slave cylinder (+ the input shaft seal) no problem.
The output shaft seal was fine but started leaking when I replaced the seal with a brown one. Changed seal again but started leaking after 5 miles. I bought a 3rd seal (not fitted yet) but decided to get another decent gearbox with 26000 miles instead (still waiting to be fitted).
When I pull the gearbox, I'll try to determine whether the leak is at the shaft or surround.
ps - on the original g/box I drilled a hole between the slave cylinder / rear input shaft bearing (per Pelican Board tutorial) so any future leaks will vent out the box rather than down the clutch actuator.
Cheers

Hello Julian
Thanks for that, I would be interested in what you find, I havn`t pulled mine apart yet as still in use for work..![[smilie=cold.gif]](./images/smilies/cold.gif "cold")
( and I don`t have the cash yet!)
Like yours mine was leaking virtually as soon as replaced, I fitted a brown one, the same colour as came out so looks like the previous owner had the same issue....and why he sold me the bike..
Its not a bad job to do if a little time consuming but I don`t see the point just for it to happen again, I`am just plucking up the courage ( and finding the time) to get the box out and inspect the output bearing in the hope its wear there?..)

There is a breather on the gearbox. And i don't know how you over fill a boxer gearbox. You'd have to lay it on it's sidePhil Thomas wrote:Does anybody know whether there is a breather on the gearbox? Certainly if the gearbox is over filled pressure builds up...and the seals do leak!

No problem, and yes, i rebuild gearboxes.Herb wrote: I think the guy I am thinking of is Steptoe. Hope he does not mind the name check.
The new output new seal is usually put back in exactly the same place. Sometimes the output shaft has a polished section where the old seal has worn it shiney. This can cause a leak. If your's is very shiney or you can feel an edge with your finger nail then put the seal in a fraction more or a fraction less.
