You need a manual, as you need torque specs for the entire assembly of the primary cover, inner primary bolts, clutch hub nut, compensator, starter bolts, starter jackshaft bolt, swingarm pivot bolts and rear axle nut.

What I know off the top of my head:

1.) Primary cover bolts: 14-21 ft lbs
2.) Inner primary bolts: 18-24 ft lbs
3.) clutch hub: (left hand thread) 55-60 ft lbs
4.) compensator: 150-165 ft lbs
5.) starter bolts: 24-28 ft lbs
6.) Jackshaft bolt: 18-22 ft lbs
7.) swingarm pivot: ?? I *think* it's 90-110 range......
8.) rear axle nut: 60-65 ft lbs.

thanks. dont have the cash for a book at this time.
That's cool....being an older bike, you can score one on Ebay maybe after you get the bike back on the road.

yeah local shop sai he would do it for $300 including parts and labor. i think i can get a belt at work for nothing and then just have to get fluid and gaskets,so i could come out pretty cheap.

$300 !!! Pay the guy to do it for ya, IMO.
Without a manual as a guide you'll get lost if you've never done a belt R&R before.

someone answer me a question.... how can the MoCo spec a torque setting of BETWEEN 14-21 ft lbs? so....you can torque a bolt to 14, or almost DOUBLE that to 21 lbs? wtf?

I ask, because they say that you have to have a tolerance of less than .003 to do a gear drive conversion...but then put out a spec like that

You do realize the difference between 14-21 ft lbs is minimal and a ratio so small on that type of fastener, that even doubling the low number, in most cases, you wouldn't do real any harm. You're given a wider range for torque ON NON-CRITICAL FASTENERS.

Critical fasteners have far less of a torque difference. Note compensator... 150-165. Only a 10% difference.

Inherently....torque values differ to some degree between different brand wrenches, wrench age, condition, bolt cleanliness and thread pitch condition.

Hence why a range is given. Stretch bolts have no range and head bolts even less.

This isn't Harley's spec. it's S&S's spec.

Its also not a torque spec, rather a tolerance spec related to/for gear lash, as the drive gear I'd mounted to the crank and runs the rear cam.

In addition to what has been said about torque specs. By using the lower number of range on lets say a 90-100 ftlbs. During a check of those bolts if it does not move then your good to go. If it does move, you can go to upper range of spec with out damaging any thing. If your already at top range of torque spec there may be other issues if it continues loosen up. IMOP

Hope you ordered a shop manual as well. If not there's a good chance you'll be paying the 450 plus what you've already spent. Just saying

I believe you will also need a couple special tools to do the job , the manual will list these also .

If you do not have the mechanical skill, I highly recommend you take it to a qualified mechanic. It not as easy as it seems. Good luck.

If you can't afford a manual.... you will be paying more than $300 to undo the damage you are about to create.... FYI... clutch nut, reverse thread... you're welcome.
