Anyone know the torque value for the oil drain plug on the deep sump motors?
Thanks, Jeremy
42Nm
Are you sure that's for the deep sump motor? That's only 3 Nm less than the standard Duc motors, which have a much larger drain plug. ???
30 ft/lbs! No freak-en way, a recipe for a trashed engine case! Honestly dont know the exact value but I tighten mine with a 4" allen wench good and snug. You'll know its tight enough when you quit feeling it "give".
The figure of 42Nm is from the workshop manual states the size is M22 and gives min/max figures of 38/46

Workshop manual for what bike?
My Multi 1000 workshop manual says the same thing...but that is the standard Duc drain plug. I'm looking for the value for the
deep sump engines (999, S4Rs, 1098, 848) which have a
much smaller drain plug.
Anyone??

Applicable to S4RS which has the deep sump motor

Thanks...didn't see that thread in my search. Looke like it's about 20 Nm:
Lower sump oil drain plug M12x1.50 20 18 22
Not to knit-pick and I respect the published values but still think 20 Nm is is an overkill for a 12mm bolt who's job is to simply plug a hole. Ever put 15 ft/lbs on a 6mm socket head screw? it will barely take it. Plus remember you got to break it loose with approx 20% more torque.
Just my opinion..

A 12 mm bolt is a bolt where the threaded part is 12mm in diameter, not the head. The other spec in Triple J's post (M12x1.50) is how course or fine the thread is. If you look at this chart http://dodgeram.org/tech/specs/bolts/M_bolts.html
you will see the 20 Nm meter spec is well under the value recommended in the chart. Most likely because the fastener is not clamping anything, but plugging a hole and is threaded into a cast aluminum structure. Too little torque and the plug may fall out, creating an involuntary oil change.
My manual says Capo is correct. 42 Nm X .74 = 31 lb.ft.
Does sound a little high to me too, but it ain't

It sounds high and my drain plug stripped before my torque wrench clicked. I set it at 30 and thank god it only stripped the driver hole and not the engine case. I will be using an easy out and buying a new drain plug for my next oil change.

That's weird because Carlos' post for an S4RS is supposedly from a shop manual. ???
No way I'd torque it to 42Nm. That's the torque for a regular drain plug...which is a much larger bolt. Have a ball though. ;)
I just went down and looked under my bike and that plug is no where near 22mm - maybe 10. FWIW it's one of the bolts/nuts I don't use a torque wrench on myself. I think the factory makes the four screws on the bottom plate and the drain from very soft material so we can't screw up the engine case so easily.
That 42 Nm figure came out of my s4rs factory shop manual, but that can't be correct. [bang] [bang] [bang]
