ringo . . . to chg the mainshaft seal. . . you don't have to remove tranny.
1)drain tranny and remove and/or loosen the left riders footboard
2)remove the back shifter lever
3)drain primary fluid and remove primary cover
(you'll have to remove the left rear passenger foot peg to get to one of the primary screws)
4)remove the primary chain tensioner shoe adj screw
5)remove clutch basket, primary chain and compensating sprocket (you can do this all at once) remember compensating nut removes and installs differently unlike the clutch asmbly. You will need to get a manual anyway for the torques values, etc. It will show you under the "Primary Crankcase Section" also, you'll need the special longggg socket tool to remove the mainshaft nut. It's 1 7/8 inch. I bought one at autozone, cut it in half and welded a pipe in between to give it the length I needed.
6)remove the starter jackshaft
6)remove the inner primary and watch out that you don't drop the starter bushing. If you do remember how it went in or it'll be backwards when assembling.
7)now is where you'll need that 1 7/8 socket to remove the sprocket nut (counterclockwise on that one with impact and it'll come off easily)
NOTE: when you remove your inner primary, if the starter bushing drops it will be in front of the sprocket hiden. . use a magnet.
8)once the nut is removed, remove the rear sprocket (you'll need to loosen the rear axle a bit to loosen the belt)
9) wa. .la. . . there's the seal. To get it out you need to be careful. I drill tiny holes on each side in the middle of the ring and screw screws in it a bit to pop it out.
10)clean area well. use a magnet to pickup any debri
11)wd40 the new seal and install evenly until flush
now reverse everything
to assemble. Go get that manual.
I might have missed something, I just slapped this out to you to get you started. . .if so, check your manual (Touring)
This will take approx 3 hours to complete. Most places will charge approx 300 to 400 to do this job. don't forget, when in doubt (mark it) also, you'll need new gaskets for whatever you take off. . .good practice.
good luck!
