Sump gasket

[tunnelrider]

After getting my sump pan welded to fix a couple of cracks from bottoming out off road (damn should've seen that corner!), I used a new OEM gasket and Hylomar blue sealant, as suggested by the Clymer manual.  Although I didn't check if the sump pan was warped, it has not leaked for two years.

Not sure if you've already tried the hylomar blue as I recall reading it was originally used as an aviation sealant but it's not very expensive. The torque setting for the sump bolts is low - only 9Nm.

The rather extensive bolting arrangements on the sump will nicely take care of anything short of outrageous warping.

I really should either replace my sump or have it welded properly too. Preferred course is to buy a good 2nd hand one and then get mine fixed so that it can later be put on the R100.

Hello Tunnelrider,
Actually, the torque is quite high. Bear in mind that they are 6 mm dia steel bolts in an aluminum thread.
It is far not uncommon to find some or all of these threads to have been stripped off. And, as it is difficult to put the bike upside down, not easy to Heli Coil them ;-)
I've a friend of mine who bought a very small preset torque wrench just for that purpose. He stripped all of the thread previously and had to remove the engine from the bike to have the thread repaired... Learn from your mistakes that is
