Calling all engine specialists

I am in need of some info.

I have a oil leak at the shaft(Where the front sprocket fits on). Do the whole engine have to be ripped apart to get to that plastic seal, or is there another way to seal this leakage?

Leaking at a rate of 1l oil per 1500km of cruise speed which is a big pain in the ass!!  :shock:

"Did you blow a seal?"

"No, that's just ice cream in my mustache."

That seal can be replaced without tearing in to the engine.  Once the sprocket (part 28 ) is off, remove the spacer (27), and the oil seal (26) is there under the spacer.  



Use some sort of improvised hook-like tool to dig out the seal.  Doing so will trash the seal though, so have the replacement in hand before you pull the old one.

Be careful to not scratch the insides of the hole that the seal is recessed into, and the countershaft itself, or the new seal will leak.

Stretch, you are a legend!!

Thanks for the info.

Thanks.

Mind the horns.

On mine the spacer didn't want to slip out.  I drilled a small hole in the metal rim of the seal so I could put a sheet metal screw into it and pull it with that
( little slide hammer body puller works a treat).  I then went to hardware store and found an appropriately sized PVC pipe couple to tap it into the seat.

The spacer marked 27? My Tiger dont have that. Sprocket is connected strait onto the shaft... interesting...

My seal arrived today, will hopefully install it tomorrow. Did you lay the bike on its side when you installed it? Just wondering if it is necessary? I want to prevent the oil from spilling out.

[Stretch]

It wouldn't hurt.

Sorry, i talked shit. The spacer no. 27 was in place.
Oil seal is replaced, just have to get rid of some nasty chain noise!!

[Stretch]

The spacer no. 27 was in place.

Sitting inside the seal, right?  I swapped my 17-tooth trail sprocket for the 19-tooth road sprocket a few days back, and although the spacer doesn't jump out at you, it sits inside the seal, allowing you to torque down the 36mm sprocket nut without binding the outer bearing race and seal.  The spacer takes the pressure and backs up against the inner race of the bearing, which in turn backs onto a shoulder on the countershaft itself.

Sorry to bring back an old thread...

Here is my countershaft seal leak: (attached photo)

The leak is coming from the OUTSIDE surface of the seal where it meets the engine case. Seems like this may not be fixed by just replacing the seal. The leak is slow at this point and I will likely just monitor it but I am wondering if anyone has and advice or special suggestion on how to cure this?

Unless that`s just crap round the south west side of the seal, it looks like the seal was damaged when it was installed. More likeley than the engine case damaged. A new seal CAREFULLY fitted should stop that. Maybe a little smear of thin oil or liquid sealant on the outside diameter to help it slip in.

Ray.  :roll:

the bottom left quarter looks like it has been banged into place a bit too vigorously, either that or someone pushed it in too far and tried levering it back out some - i love speculation... :D

It might require speculation but the beauty is a guy in Washington asks a question and two guys from across the pond jump in to help.

Thanks for the thoughts guys! I have a new seal on the way (along with a few other bits) so hopefully a careful install and some gasket maker on the outside will do the trick.

Anyone have experience with removing the spacer behind the sprocket? Mine seems pretty well stuck in place. I will try to take some pictures for a CS seal replacement tutorial to add to the hall of wisdom.
