Gear Shift Seal?

[porndoguk]

after doing a tidy job of running my new rear brake hose through the swinging arm, i noticed that the gear shift shaft is displaying signs of a little leakage, not dripping just collecting around the area.

what size O Ring is it and/or where can i get one?

and whats the procedure of replaceing it, i assume the drive sproket cover has to come off, and ill assume the engine oil will need draining?

Hi,

there is two seal behind that sprocket cover; the output shaft seal (which will need the crankcases split to change) and the clucth pushrod seal (which is fairly easy to change with no splitting of cases).

First find out which one is leaking, take of the sprocket cover, look for traces of oil, can be very hard to see, so best bet is to clean off all the muck and grime. Then take some oridinary bearing grease and trace a circle around each seals outer edge. Put the cover back on and take the bike for a spin untill it reaches normal operating temp (80-90 degrees).

when returning home take of the sprocket cover and look at your two grease markings, the hot oil coming past the seal will have made a very visible trace through the grease and the culprit is identified.

When you know which seal it is, give us a post with as pic and I give you a step by step..

And oh, check your oil level, the seals usually blow due to overfilling

Hope it's not the output shaft seal.. you'll need to take the crankcases apart as already mentioned to change this.. bit of a ballache

yeah just a bit, its not that bad, its like dusty crap collecting near the splines saying that it could be from my chain as i super lubed it last week and i need to clean round that area anyway!

All looks good to me dude.

Get yourself a gallon parafin and brush it all over there and work it in.. I use a large paint brush (you can collect the parafin with a drip tray) i've got some thats black as coal and had about 5 years but still does the job) slowly going down as you loose some each time

after leaving it 5 minutes hose it off and everything will be spankingly clean!

had a mess after you left with some of that VPOWER in the big jerry can, well what was left in my homemade aux fuel tank, and its now all sparkly clean i even found a brand new exhaust stud/nut that was obviously droped in the oily goodness that was left from the previous owner, at this rate my bike will weigh much less aswell!

Haha good stuff!

Petrol's ok but bear in mind.

It's more penetrative than parafin so if you get it into bearings it'll strip the grease much better.
The fumes are really bad for you
It's really flammable!

Still glad it got that little patch up nice and clean :)
