Belt too loose?

Yep, as OKCTriple said his dealer told him on his service the other day, the chirp is indeed a loose belt. How can I be sure? I tightened mine and it was chirping like mad till i did that. After: ZERO CHIRP.

As his dealer told him they are supposed to be quite tight. 10 Lbs of pressure against the belt is supposed to only move it 1/4" I checked mine and i move it a full inch with my finger using what i would estimate was at most a couple pounds if that. So thats pretty dang loose. In fact, i think they all came quite loose and mine loosened up even more as i'm sure everyone's has. The dealers don't normally work on belts unless thier mechanics have been harley mechs in the past or some other belt driven brand. So i'm betting they don't know much.

Theres also a little gauge built into the lower belt guard. Look at OKCTriple's post in the tech section and i think it was mustang who posted some pics of it. Sorry if i got the wrong guy, but i think it was mustang.

I wonder of they stretch just a little when new. I'll check it out, thanks! Daz, did you get that manual? What's the procedure for tightening if need be?

dazco · 10-05-2009, 10:19 PM

Yeah, they do. And yes, i have the manual but it tells you how to do it with the tool you'd have to buy. you don't need it tho. It's really quite simple. Push on the belt 1/2 way between the front and rear pulleys and see how much pressure it takes to move it a given amount. the ideal adjustment would be that when pushing it with 10 Lbs of pressure it moves 1/4". I just adjusted it to where it was at 1/4" with probably 1/2 to 3/4 of that and the chirping went away. I fear it being too tight so i just left it there. But if you have a good feel for things like this i think you can get it plenty close enough as i feel i did. Also theres a oblong hole in the lower guard that is hidden by the muffler. But the muffler has to come off anyways to get to the axl bolt. You can use that hole as a guage as described in that thread of OKCTriple's. Just another way to do it.

anyways, the procedure to tighten it goes like this..

1)-remove the muffler bolt that holds it near the rear and remove the heat shiel to get to the hose clamp that clamps the muffler to the cat. you can either remove the muffler or swing it a bit out of the way to get to the axl bolt.

2)-loosen the axl bolt

3)-loosen the outside nut on each side of the axl adjusters and spin it a bit out of the way.

4)-turn each side an equal amount, say a 8th turn and check the belt to see how much that tightened it. repeat doing a little at a time till the belt is where you want it.

5)-torque down the axl bolt then the outside nuts on the adjusters on each side to lock the adjuster nut in place

Remember to turn each side the same amount each time so as not to throw the alignment out. Also you can use the markers in the frame and adjusters on each side to make sure they are both in the same place, tho DO turn them the same amount each time anyways and use the markers to check and be sure it's not off on one side from the other. This is probably mostly known to you having adjusted chains in the past unless this is your first bike.

Yes, sorry. I should have sourced my information to OCKTriple. He documented it first in his thread. I was in quite a hurry yesterday.

Do you know the torque spec on that axle nut?

If i recall it was in the neighborhood of 80 Ft Lbs, (108 Nm) but i would have been more likely to remember had i torqued it.....i didn't have the right size socket. I looked at at the spec before i saw i didn't have a socket so i DID see what it was.

So i had to use a monkey wrench. But i'm pretty sure it was in the 80's....88 (119 Nm) seems to ring a bell. by the way, i like to use Ft Lbs vs Nm just because i'm used to that so i wrote all the Ft Lb equivilents next to the Mn specs in the manual using a program called "convert".

Now for MY question.....anyone know what size that nut is? I assume it must be in the manual but thought i'd ask so i might pick one up today at lunch.

daz - are you referring to the two nuts pictured here near the bottom center of this photo? If so, they're 14mm.

No, the axl nut.
