Honda CBF600 2009 oil weep

[voxy53]

Hi All
I have noticed a slight oil leak coming from the front sprocket area of my bike
I am just about to replace the front and rear sprocket and chain, so I have also bought a new pinion oil seal which I am hoping I can change after taking off the front pinion
Has anyone done this job and if so how did you remove the old oil seal ?
Thanks for any advice

Dont think this seal can be done from the outside as the seal has a lip which sits on the inside, but could be wrong

Are you talking this,

I dart/pierce the oil seal at an angle in the middle more so away from the output shaft and lever against the casing with a lollipop wood stick.
If this fails then i dart 2 holes and use thin self tapping screws or chipboard screws again avoiding the shaft and pull the seal out.

Also check if the engine crank case is breathing.

Before you do anything drastic, clean out all of the chain lube and crap that accumulates under the cover and then see if you still have a slight leak.

Hi All
Thanks for your replies
Yes you are correct Meatybeaty
There is a lip on the inner edge of the seal which presumably stops the seal coming out
If I can get the old seal out I suppose I could take the lip off and push the new seal in with some adhesive around the edge !! Not good practice though !!
I haven't taken the sprocket off yet to see whether there is a casting that can be taken off to remove the seal
I can't believe that Honda would require you to split the cases to replace this seal (if it has gone )

It's more likely to be accumulated chain lube fling dribbling down than an oil leak. We've been here before with others.

A lot of lube with a hot seal (stick it in boiling water for a couple of minutes) and that lip will pop into the gap from the outside no trouble.

As Islander and Stinkwheel have said, it isn't the seal. It's grease and gunk around the front sprocket, which is melting and dripping down when the engine is hot.

Hi All
Thanks to you all for your useful comments
I think that changing the seal by taking the lip off may be a bad idea !!
I think that the problem IS the grease from the chain melting as some have mentioned, so I will clean the whole area when I take off the front sprocket
Just as an aside, there are no drips from the bike at all on the ground.
I have a bit of work to do over the next couple of weeks
I will be changing the front and rear sprockets and chain ( but not the oil seal !) and have just bought a scottoiler esystem with a twin outlet to lubricate both sides of the chain which should lengthen the life of the chain and sprockets
Has anyone got one of these fitted to their bike and if so are they happy with it ?
Thanks again

Love my scotoiler but the twin applicator is no good on my bike (single sided swingarm) as it sprays oil on the brake disc.
