Spent all day trying to diagnose the clutch dragging problem, as well as a nasty sound the clutch makes when it's disengaged.Most of the day was spent on the kicker cover. Fuzzy from Classic Thunder said that newer kicker covers don't have adequate clearance for the older heavy duty throwout bearing. I used a Dremel to grind down the spots that seemed to be too high.
Didn't really help. I decided there is a clearance problem on the clutch side. Tore the clutch all apart, and was trying to get the hub nut loose, and I broke two of the clutch studs. Not the end of the world, but a setback. I think I figured out that the sound I am hearing is the rear belt pulley rubbing on the inner primary when the clutch is disengaged. Starting to wonder if the BDL belt drive is worth the hassle. It's probably not installed right.
I think at this point I may have to get it to Fuzzy, and let him help me diagnose it. I will get his advice on whether to try to work out the belt issues, or switch back to the OEM chain primary.

Had a revelation last night about 11:45pm and realized that the clutch hub nut is reverse thread. I feel like a complete moron. I put the back wheel up against the garage with the transmission in gear, and stood on the rear brake, and got my longest torque wrench, and I got the nut loose. The hub is not all that expensive, and there were some grooves worn in the clutch alignment pins, so I will probably replace the whole assembly.
ReplyDeleteThe back of the transmission pulley and the inner primary appear to have been rubbing together. I think I will need Fuzzy's help to figure out what's up with the primary spacing.
Jim helped me to drill and press out the broken studs. They came out really nice, and replacements are available from V-Twin. They are "peened" on the back to hold them in the hub. Not exactly sure how to do that, but I may try it.
ReplyDeleteI think the noise I hear is the back of the transmission belt pulley rubbing against the inner primary. Seems like there is very little clearance between the final drive chain and the inner primary, so no room to shim the inner primary farther from the transmission pulley.
