Alternate uses for a power head.

Does anyone make a belt pulley that adapts on a saw in place of the drive sprocket, or is everything custom? Was thinking of using my old Jonsered to drive a water pump up at the pond

You may be able to use a pulley off a Husky cutoff saw. What kind of pump?

I would guess that you may have a problem with getting the thing started since low-end torque is probably not that high. Also, you'd probably have to get some big-old pulley on the pump, as typical centrifugal pumps run at about 3k rpm. Still -Good luck!

I have recently set up a system to pump water from a pond. It can be a pain to set up, but once it's running it is a real convenience.

What size Jonny, how much water, how much head, how much draw, what kind of pump...lots of ?'s to be answered.

Unless you only need small amounts of water, I'd think that saw powerehead would be a poor choice. Cooling could be a problem...chainsaws were just not meant to be run at or near full output for hours on end. Fuel economy would be abysmal...compare lbs fuel per hp/hr to a small 4 stroke. You'd have to rig up some remote tank too, because I'm sure you don't want to walk down to the pond every 15 munites to gas up.

That said, I'm sure it wouldnt be such a big problem to bore a hole in an aluminum pulley about the minor diameter of a rim drive sprocket, carefully lay out and drill some small holes corresponding to each drive tang and saw or file out the waste. Lay the pulley on the drum (should center on the minor dia.) and carefully pour some resin filler (epoxy or polyester) in the spaces around the drive tangs.

If you decide that you don't want to continue with the idea, you can heat the drum up to about 400 degrees which will degrade the epoxy or poly resin to get your drum back. The aluminum pulley will be a loss.

Good luck!

Steve,
What kind of set up did you make? I was thinking of finding a stand alone pump head that I could mount a good size pulley on and run a small pulley on the power head, and mount them to a steel our aluminum plate. I have the power head and am sure I could find a pump head for a good price if I look around.
My primary motivation was/is to use the power head, because I have it sitting around and get the water out of the pond and into the pasture with out spending a lot of money.
May be it doesn’t make sense, but I am looking for ideas for the power head that can no longer accept a bar.
When I bought the PH many years ago, the studs were helicoiled and over time they have given up and there is not enough metal left to put new ones in. Just looking for ideas as to what I can do with it.

Why not just use a small horizontal shaft Briggs or Tecumseh engine? They're almost free around here and are made for this kind of thing.

I wouldn't use a saw powerhead for all the reasons specified. Plus the noise!
