2000 Monster 900ie]Clutch Release Cylinder Bolts and Gaiter Orientation

[scuro]

Is there a torque value list specific to a 2000 Monster 900ie that I'm overlooking? I am using the original service manual (which only publishes settings in Italian) and the Haynes book.

In the meantime, perhaps someone could help out with the following? I believe they are M6s.

1. The 3 release cylinder (clutch slave) mounting bolts
2. The 3 front sprocket cover bolts

Also, I pulled the release cylinder off today and lost track of the proper orientation of the rubber gaiter. I could make an argument for either direction : / Anyone familiar with it?

Thanks, DarkMonster. I'm aware of that post but hoping to find something specific to my bike. From what I can tell, there are differences.

Working out torque specifications on a monster seem to be a total cluster.... well, you know. Contacting Ducati directly hasn't been productive and the few times I have talked a shop into giving up a setting, they just contradicted the previous shop. Honestly, I'm starting to wonder if the Ducati engineers documented anything in the first place.

In this case, I'm not too worried about the sprocket cover, but the release cylinder screws were really on there. I wasn't sure if they seated extra tight over time because of the counter force of the rod, or if they were torqued that much in the first place.

I guess I should clarify that I believe my original service manual suggests about 9nm for an M6 in general, but that wouldn't explain the force I had to use to take them off. No loctite residue seen on the threads either.

Original Service Manual Torque Spec
Viti e Dadi in Generale....6x1....7,8-9,8

Over time, steel screws in an aluminum case will get tough to remove.

I basically do "that's it"  . ..  screw stops turning, go for 1/4 turn with 3/8"ratchet

Nice, thanks guys. The steel on aluminum thing could definitely be part of it.

Just in case another '00 900 ie guy checks the thread later, I ended up going with ~9 nm for the screws, but will be checking them again after a few rides. And I placed the gaiter with the smallest hole around the rod (facing the motor) and the rest of the rings tapering down towards the slave.

Yeah that's how I ran the gaiter on my old oem slave cylinder.

For sure run grease or anti galling paste on the threads.

I have lost the link, but I found early (read: Bevel) Ducati torques specs that basically equated to "tight."

 Way back when Cycle magazine did a story on torque requirements for allen head screws. They determined that if you use a standard length allen wrench you can not over tighten the screw by hand. When you use as much force as you can on the long side of the wrench it is just the right amount of torque.

I can do 15 ft-lb on a standard 5mm hex key that's ~5" long.

OEM spec on typical 6mm bolts, like the ones that hold the clutch slave on, is 7.5 ft-lb.

YMMV
