Thread sealer or PTFE tape?

[Beancounter]

The final drive housing on my R1150GSA has a very slight leak. Shopping with new crush washers, would PTFE tape or leak sealant/thread sealer be a better option?

Tried be crush washers but they don't do the leak entirely.

Which part of the housing?

If it's dropping from the bottom, trace it up to the actual weep.

The reason i ask is that often the gearbox output shaft will weep and the oil will run down the drive shaft and then weep from the bottom of the rubber gaiter, making it look like the final driver is weeping.

If it's the gearbox weeping don't sweat it, the output shaft is higher than the mean level of the oil so it only weeps when in use, which means it won't lose much oil.

It's definitely the FD housing, specifically from the drain bolt, all other parts of the swingarm and FD housing are dry. I suspect we've slightly warped the drain bolt hole when we needed lots of heat to remove the FD bearing a couple of years ago.

Have used yellow PTFE and the thread sealer, test will be tomorrow morning riding to the office.

Try a softer crush washer?

I had something similar on the ZXR400 once, i used silicon sealant on the bolt and crush washer, not up the threads, and it worked fine.

Perhaps get hold of some Gas PTFE tape; it's a lot thicker and stronger than the PTFE tape used on water pipes etc.

If gas PTFE tape is yellow then that's what I've used last night. Drian bolt/hole is still weeping, not as much as before. Back to the drawing board before I shell out £350 for a second hand FD unit...

lol shelling out for something is £1000+ not £30k. You spend that on a round these days
