Compensator Carnage!
http://picasaweb.google.com/rodwgreg...eat=directlink
A good riding buddy owns this 2003 springer and is all the time telling me how good it runs and that he NEVER as to do any work to the bike.
I don't think that way.. I take the time to pull covers on my bikes to see that all is well every so often.
Guess from owning a 68 Shovel head for 25 + years.
The picture in the link above shows what can go wrong when your engine nut comes loose!
The inside and out of the rotor was beaten and grooved, the Cover or compensator spring was broken, the sprocket and spacer was trying to weld them selves together and the engine nut had no threads left.
This could have been much worse but as it is I only had to replace the stator, rotor and all of the compensator parts which comes in a kit from V Twin.
The power shaft threads and splines needed some careful filing for the new engine nut to screw back on.
The Threads in the original engine nut were beaten to death and the inside of the outer primary was ground almost all of the way through.
It appeared that NO loctite was used on the engine nut..
The threads were cleaned well and loctite was used this time.
The new charging system works great as well as all of the parts fit as good as new.
cost for the parts was around $400.00
He was lucky..

A compensator sprocket nut coming loose will never happen to me. I run a compensating sprocket with a nut lock. http://www.emcv2.com

Wow, I'm not alone! My Deuce had the nut come loose on the Compensating Sprocket, but I caught it before coming off. My first inclination something wasn't right, when decelerating I got a lashing sound out of the primary case. I first thought was my chain was loose. While attempting to adjust the chain it would tighten up then I would spin the chain and it would come loose again, Not good. I began checking all attachments and the Sprocket nut was the first. Bingo!

SERVICE BULLETIN
M-1170 May 27, 2005
COMPENSATING SPROCKET TORQUE PROCEDURE
®
Purpose
This Bulletin documents a torque and turn-of-nut procedure
for tightening the engine compensating sprocket. This procedure
improves the clamp load on this assembly and replaces
the present tighten-to-torque procedure.
Motorcycles Affected
All 2003 through 2005 Touring, Softail, and Dyna model
motorcycles including CVO models with Twin-Cam engines.
Production vehicles began using this procedure May, 2005.
Dealer Action
Update all service literature and notify service technicians. To
assure this procedure is used, insert this Service Bulletin
number in the TORQUE VALUES tables in Section 6.1 SPECIFICATIONS
of the Service Manuals covering Touring, Softail
and Dyna models for model years 2003 through 2005.
Instructions
1. See Figure 1. Before installing the clutch, primary chain,
compensating sprocket and shaft extension assembly do
the following:
a. Clean threads on engine sprocket shaft (1) and
internal threads in sprocket nut (2) with LOCTITE
7649 CLEANER/PRIMER, Part No. 98968-99.
NOTE
If a new sprocket nut, with lock-patch, is being installed the
clean/prime of the internal threads is not needed. If the nut is
being reused, clean the internal threads as specified in step
a. above
b. Apply two drops of LOCTITE THREADLOCKER 262
(red) to the threads on the engine sprocket shaft.
c. Apply engine oil to the complete underside (3) of
sprocket nut (2). This is the area that will contact the
sprocket cover.
2. Follow the Service Manual procedure for installing the
clutch, primary chain, compensating sprocket and shaft
extension as an assembly.
3. Install sprocket shaft nut and hand tighten. Follow the
Service Manual procedure for installing the clutch hub
mainshaft nut.
4. See Figure 2. Tighten sprocket shaft nut to 75 ft-lbs
(101.7 Nm).

Figure 2. Tightening To 75 ft-lbs (101.7 Nm)
5. See Figure 3. Scribe a line (3) on the sprocket shaft nut
(1). Continue the line on the sprocket cover (2) as shown.
6. Tighten the sprocket shaft nut an additional 45° to 50°
(50° MAXIMUM).
