I need some help please......

My bike has started to leak quite a lot.

It looks like its coming from behind the front sprocket, its a dark red in colour
and seems to be a thin viscosity.

It doesn't smell of petrol either. I just wanted your thoughts before i started pulling it apart

Thanks [/code]

Sounds like the front sprocket oil seal has gone and it,s leaking gearbox fluid Take the front sprocket off and you can get to the oil seal out and fit a new one (well that,s my idea anyway but will wait to be proved wrong)

hi ,iv`e just replaced my oil seal behind the sprocket.same problem oil seeping from behind the sprocket area. i also replaced the one on the gear selector shaft as that was old and hard, easy job though , anyway the parts cost £3.78 for the gear oil seal and wait for it ,£8.50 or so for the sprocket one. from leisure trail.but next day delivery so not that bad

remove sprocket ,use a small screwdriver to carefully remove the old one.there not that bad but be careful not to damage the casing.you can put in a self tapper to remove but the seals are hard and can be a pain getting the screw to start. dip the new seal in gearbox oil then tap in with a socket keeping it straight.top up gearbox oil as i lost about half a pint doing mine,hope this helps

yeah - mine both went just after got the bike as well. Though i did struggle to get them out they did come eventually. Just make sure you fit the new ones the right way round, and as mentioned before, don't damage the casing !!

Lean the bike up against a wall at a bit of an angle then you don,t get any gearbox oil leaking out
