Oil leak near front sprocket
« on: February 06, 2020, 07:37:39 AM »
I've been noticing the odd drop of oil on the garage floor recently, and it's location suggested it might be chain lube, however a couple of days ago there was a more substantial amount, and it was clearly engine oil. I removed the front sprocket cover and could see that along with a build up of chain wax (which I've been using over winter) there was clearly a build up of oil directly beneath the sprocket in the 'V' of the engine casing, with staining down from there towards the side stand switch. I topped up the oil at the weekend to the upper mark and yesterday the level was in the middle - I'd ridden about 50 miles in the interim.

Is this likely to be a failing/failed output shaft oil seal, or are there other possible areas it could be? I couldn't see any staining above the sprocket. The chain and sprockets were changed about 2000 miles ago, the bike is on about 22k miles.

If it is this seal, is it a relatively simple job to replace? I'd be getting a mechanic to do it.

Thanks in advance.

I believe you can prise the old seal out using a seal removing tool.

I not 100% sure, but I'm sure a member will clarify it :084:

While in practice a good tool for the task the issue is accessibility, I think you would struggle to get that tool in and manoeuvre it. :084:

Thanks for the advice, Ive managed to find a mechanic with main dealer experience who is going to look at it for me.
