I've been searching for the last hour and I can't seem to locate a thread I know I've seen here...
Dave, didn't you have some issues with a leaking oil seal on your H2? Does the parts diagram show the wrong location for the thin O-ring that goes on the shaft behind the primary sprocket?
The O-ring is shown outside the oil seal but should be between the spacer and the bearing, if I remember correctly. Can someone confirm or correct this?
Also, am I remembering correctly that this oil seal can be replaced without splitting cases??
Thanks,
Neil

Yes, the oring goes between the bearing and spacer. The spacer has a larger chamfer on one end, you'll want to size the oring so that it compresses on the bearing, shaft and chamfer but not prevent the spacer from seating against the bearing when the sprocket is torqued.
No need to split the cases for that one, it's the clutch pushrod seal that's the bugger.

Thanks, bud.
Looks like the 'ol memory banks are firing on all 3 cylinders these days...
Cheers,

The proper O ring was still active at Kaw last I needed one. It has only about a 1 or 1.5mm cross section width. Be sure there are no corrosion pits on the sleeve where the new sharp seal lip will ride (or a leak will result). Both ends of the spacer have the same chamfer so you can flip the sleeve as required...The chamfer is too small to contain the O Ring, so the O ring always gets squashed and wrecked.
I suggest you re-torque the sprocket nut to 85 lbs (the Kaw specified torque) after it has been run for a bit. Use blue Loctite too...

Thanks Scott.
I'm not sure if there's even an O-ring in there right now. And the sprocket nut was loose but held in place by the tabbed washer, thankfully. As soon as I remove the spacer the oil comes running out but with the spacer just pushed onto the shaft the flow stops.
Luckily I had the foresight to purchase a few of the O-rings when I was building my H1 and the bike came with an OEM seal that the PO just never got around to installing. This leak has been with me since I got this bike so the fix is overdue but I'm happy to finally be getting it dealt with.
To torque that sprocket nut I just put it in gear and step on the rear brake, right? Thanks.
Cheers,
Neil

Be sure you check for and remove the old O ring, as it may be hard to see. I use a smear of RTV on the O ring to lube it and also insure it seals. Also use some 3 Bond on the OD of the ingoing seal. It was the seal's OD leaking that had Kawonda stumped for a long time with his trans leak.
To torque, simply connect the chain to the rear wheel and step on the brake (no gear selection required).

Yes, definitely use sealant on the outside of the seal. otherwise, you will need lots of o-rings for disassembly 7 or 8 times. How would I know that?  Along with kick start springs, that is my fastest repair, with blindfold too. |

Protect the bearing from the entry of swarf and put a radius on the sharp case edge too (helps prevent injury to the ingoing seal).
