Clutch install gone bad

[Texas Grizz]

3 Things that will make a clutch install go bad;
1: Getting 3.5 hours sleep over a 2 day interval
2: Installing the clutch kit on the day before you’re to leave for the big 3 day riding trip
3: Not torque the primary sheave nut to 85 foot pounds.

Well it happened after all the work with the new paint, pipe, water temp gauge, wheels & tires, and EPI clutch kit I was already for the big planed 3 day riding trip, and needless to say I rode for about 30min before the nut on the primary backed itself off. Needless to say I now have to buy a new CLUTCH HOUSING COMP as the treads on the shaft are gone and the spines on the cam are gone as well, this is about a $200.00 mistake with all the little parts seals, nuts, etc, the service manual says when replacing the CLUTCH HOUSING to replace the clutch as well that would add another $160 bucks to the already $200 bucks but I think I’m going to check out the original clutch as there’s only 170 miles total on the bike so I dough that the clutch fingers have seated in to much. Any thought on the clutch having to be replaced with the clutch housing as one unit?

Well I think I know where I went wrong besides the 3 think mentioned above, when I put the primary sheave nut on I only used the impact to set the nut then I was going to use the torque wrench to torque it to spec that’s the step I forgot to do. O-well what can you do, fix it and ride another day right? Think I might just add a little red tread-locker to the new one just to make sure.

you should be able to replace just the part that has the splines on for about 25 bucks unless the splines are totally gone on the crankshaft

The splines on the shaft, which is called the clutch housing are fine but the treads are F'ed plus the nut and the shaft have signs of excess heat build up so its better to replace them. Live and learn hehe
