Well, I guess I was having too much fun, so it's my turn to break down. Rode about a 1/2 mile today before I could hear the primary start banging from a mile away.

Before I tear into it, I'd like to hear some thoughts in case I get in over my head.

Here's some background ...

> The racket kinda goes away when I pull in the clutch.

> Parked now in my garage in first gear, the belt is hanging very loose.

> 09 Road King Police with just 13K miles on her. I replaced the stock compensator with the SE one myself 9K miles ago, so it could be simple as the nut having come loose?

If this is a main shaft bearing failure, how do I know, and is that something mechanical hack can fix?

Any guidance would be greatly appreciated.

Thanks!

..willing to bet the primary chain is slapping the cover like a pimp dishes out punishment...probably the tensioner let go...the clue is that it stops when you pull in the clutch...let us know what you find...you can't hurt anything by taking off the primary cover....go for it...good luck

 

2nd that...and the pimp hand is strong!

 

A broken tensioner or loose primary chain isn't going to cause the drive belt to suddenly hang low. Has to be something on the tranny end. I fear the worse on that one? Mainshaft bearing...

 

Are you saying your drive belt is hanging loose? I can't imagine what would cause that. Time to pull the primary cover and inspect. Let us know how it goes.

 

I would bet the primary pulley has come loose and slipped sideways on the mainshaft toward the primary. The belt now has room to slip down between the primary pulley and the tranny.

 

I will also be watching this with interest........

Replace with high torque one piece bearing!
