Compensater Sprocket

Hi all it has been a long time since last post. This place really rocks i still read post now and then. I have a custom i built. 1989 to 91 parts. I pulled the primary to look for a noise every thing checks out but the compensating sprocket is slaping back and forth. Making a lot of noise. the spring is all most non exsistant could this be worn out or broken. If so can cover assembly be bought separtely. The bike is a FXST . Thanks for your help

chucktx thanks for the reply every thing looks great the cover assembly with spring should fix it. bike has 30;000 on it. show chain and all looks good thanks for info.

Compensator Spring

Does this spring wear out often????

My dad brought his 99 low rider into the shop at 25K and they said he needed a spring replaced, but he couldn't remeber what one.

Thanks

ever since I hopped up the motor in my 02 dyna I've had trouble keeping the sprocket nut from coming loose I'm to the point of using blue locktite or tacking the nut any one else have this problem?

Hey fxdxSteve, have you considered the red locktite? I thought that was a stronger bond than the blue. Sorry if I'm insulting your intelligence, I'm sure you already thought of that, but it was just a thought.

The compensator nut is supposed to be red loctited and torqued to 160-180 ftlbs depending on which model you have . The torque spec is in the service manual. The compensator itself might be rocking because the nut is not properly torqued. Make sure you clean off the threads on the crankshaft so you can get a true torque setting. Also, if the compensator has been loose for a while, check the rotor assembly and crank assy splines to make sure these did not get rounded out while the nut was loose. If the teeth on the rotor are rounded or almost completely worn out you may need to replace the rotor.

I've been using the red using a 20 inch breaker bar and standing on it I weigh well over 200 I believe the blue is the stuff you have to heat to 450 degrees to break it loose after tightening this is the second nut the red doesn't hold. all the parts of the comp.still look like new but the inside of the primary cover shows grind marks where the nut rubs just went to the locktite website looks like red is best I'll have to come up with a new idea

That sucks fxdxsteve! I've done that too where you stand on a breaker bar like that, (not on my bike), and it doesn't always give you the torque you're looking for. Just because of the angle etc of the wrench and your pivot point. (sorry I was always good in geometry and such) I actually did what vybr8er said and did it with a torque wrench. Of course it took ALOT of effort to make that thing click at 160 lbs. Anyway, good luck with that and maybe the black loctite is the key. I did use the red on mine and so far (knock on wood) it's still working.

It seems I read a service bulletin somewheres as to shiming the nut because on certain models the nut bottoms against the hub and not the sprocket. I could be wrong here, but I just seem to remember reading that somewheres.

I chucked the nut up in my lathe and took off about .030 it helped but it still works its way loose probably something to do with burnouts and wheelies

Yuppers, it could but, don't ever let that stop ya. Half the fun of beating on them is rebuilding them. Only problem is they tend to break before a major run or when your flat broke.Hey look at it this way, at least you got decent crank bearings in that 02 and a forged crank instead of the walker flywheels and handy andy bearings with a cast crank as on my 07. LOL

new red built a stand to sit under socket to steady it cleaned everything welded an arm on breaker bar to get proper leverage got the spacer have tried all given fixes it takes a couple thousand miles to come loose so when I change primary oil I pull the primary cover and tighten it back up but primary gaskets are costly I reuse them 3or 4 times but its a pita its a given that I'm gonna go through the ritual before any trip street vibes coming up in 2 weeks so I want to do something more permanent while I have the cover off

appreciate the suggestions every bike has its own quirks I guess this one's mine been thinking of some kind of mechanical lock but don't want to throw the balance off gonna change the oil this weekend so Ill pull it apart and decide if tacking the nut to the bell will do the trick if I tig it it won't change the balance

Haven't look in my manual yet so I might be talking out of my a$$. Is there a way to put a locking tab washer behind the nut? That way after you tihgten it you can bend the tab over one of the flats on the nut. Or is there enough room to add a second nut to be used as a jam nut. Just a thought
