t5 gearbox oil smells of petrol

[aceface]

Hi
I just wondered if anyone else has had this problem, and if so is it expensive to put right, I cant do the work myself so its going be a workshop job maybe at buzz solos
thanks in advance ;

Clutch side seal has gone. It's a split the cases job so will most likely cost a few hundred quid. You should take advantage and renew other seals, cruciform and bearings while it's open as well.

It's a big job, but very doable yourself with the right tools and guidance.

As Rob says..

depends how bad it is though, I service a couple of scooters which always have a trace of petrol in the oil, seal does need doing but they have happily run on for years now with just regular gear oil changes. Personally I'd change the gear oil, run it for say 500 miles and drop oil again to see how 'watery' it is.

Then decide if you need to do it immediately, if you can tackle it yourself winter break?), and if you do want to get all the bearings and seals done at same time, that's ideal of course but it gets expensive especially if you are paying someone else to do it.

as bryno says ,double , 1 of ya seals is gone/going, if scoot still starts an idles it aint bad as in the going section, as robjack says when in there ya might aswell do other stuff ,but at 30-35+ pounds a hour it gets expensive quickly, but with special tools needed at 20-30 an bits 50-70 an your time =free , you can re-build ya engine with a manual/dvd n help from here for under a ton, check simes66 thread ,he hadnt done more than change a plug before ,
but if scoot still runs an does what ya want ,just change gearbox oil more, wickes builders merchants does sae30 for lawnmowers at 600ml for 4 quid, bargain, H
