air compressor motor mounting question

[uao85]

any ideas for a belt tensioner or tensioning device for an air compressor? The pump is mounted solid to the top of the tank, and would like some ideas for a possible way to mount the motor that would incorporate a system to tighten the belt to prevent slipping.

The motor mount plate should be slotted. Use a prybar to put tension on the motor and tighten down the bolts.

That's the traditional method, yes. The York compressors are slick for this as they have threaded holes on the sides as well as the bottom ("side" and "bottom" being relative.)

It still slides in the slotted holes, but you can thread a nut on the "side" ones and tug it into place.

Assuming your motor is not drilled in such a way, however, then Carnac The Invincible foresees a prybar in your future.

Alot of the accessories on both the crewcab engine and blazer engines have left and right hand thread heim joints on a small diameter rod. turn the rod to tighten the belt and retighten all the other bolts and jamb nuts. It works pretty good. Only real fall back is adjustment is limited so you have to nail the belt length pretty damn close.

are you talking about on an OBA style setup? do you have any pictures of what you are referring to. I understand the concept of the heim joint in a rod that you would rotate to tighten or loosen with, but cant figure out how it would be used in my application. The compressor I am mounting the motor to the top of is my shop air compressor which is an 80 gallon upright tank.

Dremu, thanks for the reply, I understand what your talking about for adjustment on the york compressors, but I dont have anythink like that on my motor or compressor head. Its a BIG compressor head with 3 cylinders and pb weighs 100lbs atleast and is bolted down to the top plate of the compressor tank. The motor is an ingersol rand 5hp 220v unit that has a flat plate on the bottom of it with bolt holes in it like it is designed to be mounted solid. This is similar to what the motor looks like.

Any more suggestions???
