Need torque value for MD5 jam nuts


Recommended Posts

I am replacing the two bearings in the front housing (nose cone) on an MD5.  I am looking for the torque value for the two jam nuts on the main shaft and pinion shaft.  I need the initial torque for the first nut (to load up the shaft and bearing races) then the final torque for the second nut.  Also, what is the best cleaner to use to prepare for red loctite?  The nuts are 1 1/8", the shaft is 3/4".  thanks

Torque jam nuts to 120 ft/lbs, then back off and retorque to 100 ft/lbs.

Use brake/carb cleaner on threads before using red loctite.

Note: You will need to lock trans shafts to torque nuts by engaging 2 gears at same time. This can done by removing the allen headed bolt from the fork for 5th gear and sliding the fork/slider into 5th gear without moving the shift rail. Then you can push any of the other shift rails below into a gear to lock the shafts.

Thanks Sean!  Really appreciate your reply.  Also thanks to your parts guy "Mike".  He spent quite a while with me making sure I got the right parts ordered!
