I have a BDS blower 10-71 question is what side does the tentioner go on. Its a smooth pulley meaning it usually rides the back sode of the belt, not ribbed side. Every blower set uip for the most part i see is the other way. Any help on this

Put it on the no-load side, which would be the starboard side of the motor. As you look at it from the front, put it on the left. It doesn't really matter if you put it on the inside(toothed side) or outside(smooth side). I prefer to put it on the outside (smooth side). Hope this helps, Eddie.

When its on the outside pushing in does it apply to much pressure to the snout of the blower and how much tension is enough but not to much. Strip thats pretty much how i see them all

The above picture in post 2 is the way I used to do it. Since then I have been told to run the tension pulley on the outside of the belt to keep the upper pulley more fully wrapped. It will grab more teeth.
I am attaching a photo that may help. Hard to see.

I keep the belt a little loose with about an inch of deflection. The engine will grow with heat and blow the belt as I have been told. Proof was I used to keep the belt tight like all other v belts and on a hard run the engine sheared every cog off the belt.

Hey brad thats how i have mine right now i just didnt know if that would put to much pressire on the snout of the blower but if u have it that way then im sure it wil be fine thanks

The only way it will put to much tension on the snout is if the belt is to tight. If it is to tight, it will either take the teeth off the belt or break the snout. It can also tear up the front main bearing by pulling up to hard on the snout of the crank. As Brad said, about an inch of deflection(each way from center) is a good place to start. Check it after a hard run to be sure it still has some play. An aluminum headed motor needs a little more slack than a cast iron headed motor because they grow a little more. Eddie

Thanks Eddie i do have aluminum heads on teh Engine so i will start at an 1.5 inches and work from there after a good run. I have a ping problem and a blewin back threw carb that also has to get resolved

Another nice thing is if push the belt in, like Eddie and Brad do, it is a little quieter, if that's what you like.
