Drive Belt Adjustment

I don't have a Harley tension tool but I'm wondering if there's another way to check the belt tension. The reason I'm concerned is when I ride with my wife I get a oil leak from the transmission drive sproket. When I ride alone I don't so I'm assuming the belt is too tight and pulling on the sproket when we are two up. I have added air to the shocks and that dosn't seem to help.

I would just loosen it up but I have heard not to get it too loose. The Harley shop set the tension (where it's set now) when they put on a new rear tire for me.I have checked other bikes in the showroom and they feel just as tight as mine.

Anybody got a neet trick for adjusting these? Can they be set too loose and how loose is too loose? If it were chain drive it wouldn't slip no matter how loose it was so I'm wondering if this belt is the same.

I don't have any neat tricks for you, as mine's still in spec - but I bought the tool from Hd to do it myself. Cost $20.

I doubt that the added weight is doing this. Check the fluid level of the trans, I'm guessing it is overfilled...
If the dealer did the work, it's either overfilled or underfilled.
The leak is probably coming from the trans vent tube, top left of tranny.

Hows your tranny dipstick look? Chrome peeled on my orginal, HD quality. I must have been abusing it. Tranny seal is leaking. Though I doubt that thin little chrome did it, but never know. Replaced with Bakers.

An Old Harley mechanic once told me that if you can twist the belt to vertical (straight up and down) then it's adjusted correctly. This was back in Evo days so I don't know if it holds true with current belts, but this guy is an excellent mechanic and I trust his judgement.

My dealer says if you can twist the belt to vertical, 90 degrees, it is LOOSE. If you can NOT turn it to verticle, leave it alone. Get the tool, it's under 20 bucks. Keep it in spec and you won't go wrong.

Thanks everybody. I guess I will buy a tool.

The tranny is not too full ( checked it level, hot) and it's for sure coming out of the shaft seal, not the vent.

It's more probable that it is your shifter shaft seal leaking and not the mainshaft. Get a small telescoping dental mirror and get a look at the bottom side of the shifter shaft and around the clevis. My seal is leaking for the second time. First time repaired under warranty and lasted about 12k miles. This time I ordered a gasket kit and shifter shaft seal from Cometic and I'm going to do the repair myself over the weekend. At least a quality seal will be in there when I'm done.

Oh and 3.37 gearing to make the labor worthwhile.

For what it's worth, I adjust my belt tension to 5/8" cold. That way when the pulleys heat up the tension on the belt will be just right. Not too loose, not too tight. IMO, the MOCO's spec of 3/16"-1/4" cold is wayyyy tight especially after the pulleys heat up. It's so tight you can pluck it like a guitar string.

It looks like the shifter seal is leaking on mine too.

This is what I was always told for a good pre ride check. Quick and easy way to tell if it needs attention.

I adjusted my belt to specs according to the manual, and thought it was just too tight. Took it to a GOOD Harley dealer to see what he thought, and he promptly loosened it to almost what it'd been before. His opinion, (and I agree) was that the factory figure was just too damn tight.

Right? Wrong? I dunno, but I know I'm a lot happier now!

I had the same experience. I adjusted mine to spec with the tension gage after replacing my tire. While riding two-up on a hot day (90's), the belt was making "groaning" sounds. I backed off the adjusters a bit and the noise went away.

If you grab the belt and twist to a 45 degree angle that is considered good. Anything less it is too tight. Anything more too loose.

I'm glad you added this post John. I just put new sneakers on my bike and using the HD drive belt tension tool adjusted it to the shop manual spec of 1/4"-3/16" with the bike on the Rivco center stand. (rear wheel in the air). I started getting the groan once it fully warmed up. Loosened it to 3/8" cold and the groan is gone.

Well, some of you may laugh at this.

I was getting a new tire mounted on the rear wheel a few weeks ago and it got done a day earlier than expected. I hadn't gotten to the dealer yet to pick up the proper tension gauge yet. I wanted to get the bike back together so I looked around for what I had on hand.

The bike was up in the air on the lift. I put my wife's bathroom scales on a floor jack and rolled it umder the belt. I had a pice of 1" X 2" wood laying around, about 8" long. I stood the 1X2 on it's end so it was between the bathroom scale and the belt and I pumped the jack up until I had a 10 lb. reading on the scale. I made my belt adjustment using this method.

The next day after I had purchased the H-D belt tension gauge I checked my belt. There wasn't enough difference to make it worth while to change the setting. Been riding for about a month and everything seems fine. I checked the belt again after a few hundred miles and it's still good.
