I took off my rightside crankcase cover in an effort to determine
if my Judder Spring was installed correctly. Getting the case cover off was fairly easy although I did have to take
a piece of wood and a rubber mallet to it to loosen it. Before removal you only have to undo the clutch cable and remove
the case bolts.
Inside was fairly straight forward. Remove the four
10 mm bolts that hold the lifter plate in place and also hold down the clutch springs to create the pressure needed to keep
the clutch disks engaged. To reinstall you must torque these to 9 foot lbs. A torque wrench that measures in inch
pounds is better for this. 108 inch pounds equal 9 foot pounds.
After getting the lifter plate off I discovered that this
released the pressure on the clutch bundle. I was able to scoot it back enough to view the Judder Spring just behind
the Clutch Center. Was only about a 3/8 inch gap to look through but good enough to see that the spring was installed
correctly. I couldn't get a photo good enough to show this. Sorry.
It was easy to reinstall most everything. But I must
say that the hardest task was removing the factory gasket where it had stuck to the mating surfaces. You have to be
careful not to scratch up the mating surfaces and not get debri in the case. I used the edge of a razorblade mostly
just dragging it across it, wearing it off. It is stuck on pretty dang good. I then did a final cleaning with
Acetone. Tried alchohol, laquer thinner and paint thinner, none of which worked.
My suggestion would be to get the tools required for the job.
I made a tool to remove the clutch lock nut out of a 24 mm socket. This worked but was a bit time consuming. I
used a dremel tool and cut off wheel. The socket did fit the nut and would have worked if needed. The other tool
mentioned in the service manual is a clutch center holder. I think this is necessary if you are going to torque down
the nut to the required setting as it will hold the clutch shaft dead still. I tried putting the bike in gear and holding
down on the brake. This would probably work for taking it off, but a bit too spoungy to get a good torque down.
