Default Do aftermarket Forge parts exist?

My forge blower has a stripped gear. It's made of a weird fibre/teflon type material. I have no idea what I can do to fix this. Is it possible that someone makes parts for these at all? It's made by Canedy Otto MFG Co. Any ideas or suggestions would be very much appreciated. Thanks

I have one with that a gear that type also,so I've read, but mines not bad ,yet
what amazes me is something like that ,that old uses a gear like that.
mine is a big sears sold cannady otto I think called the Chief.
I guess there was a reason for using that but I don't know why.

I think it's "Phoenolic" probably misspelled. lol

Try and find a Browning Power transmission dealer, they "usto" offer Phenolic gears. They also had gear prints on the page top of the catalog you could lay your gear against to find the pitch, then hope that number of gear teeth were shown. Gear may be wider or narrower than yours but it's worth a try.

Kieth Rucker on Youtube rebuilt one of these a few months back. Any good machine shop can make you a gear. Someone with a 3D printer could make one. Ebay maybe ?

I would guess they used the fiber gear (or Phenolic) for gear whine noise reduction.

Ford Flathead V8 camshaft gears were fiber as well and mine still looked good with nearly 80 years on it.

If you can't find a Phenolic gear to fit it I would think Nylon would be a good alternative.

Keep us posted on what you come up with for it.

How creative are you? If you can get the blower apart to get to the mating gear or find a metal gear with the same tooth size one can make a mating gear from Delrin by rolling the proper size Delrin blank into the heated metal gear. Easiest to do in a lathe, but I thing that a jury rigged setup would do.
Search the net, you may find a how to video.

Model A Fords had fiber cam gears too

Pull the gear out and measure it up.

Forget entirely, about make, model or what machine it's on. It's just a gear.

You want to know the outside diameter and tooth count, with which you can determine the Diametrical Pitch of the gear. Look up the info online for calculating that. You either add or subtract two to the tooth count, and divide the diameter, or sumthin along those lines, and it gets you a number. I am not trying to be funny, I simply look it up when I need to.

Unless it's a weird custom, it should have an end result of a whole number, likely in the low teens, from the look of it.

Metric gears are described by their Module number, inch sizes by Diametrical Pitch. Width and bore size will finish off the collection of stuff you need to know. Those will also usually give you a clue as to whether the gear is inch or metric.

My buck says the gears are 14 1/2 degrees pressure angle. Could be 20 degrees, but that is a more common thing in new equipment.

Once you have the info you need, you start searching for gear suppliers, and hit their catalogs. Pick what you need, order, pay. Install. Done.

I wouldn't go too far out of my way to find another phenolic gear, but suit yourself.
Typical rate at retail for gears is about a buck a tooth, Buying them from stock is cheaper than having them made.

An update on my blower. I tried finding someone to sell or make the gear. I don't know if it's because we are in oilfield country or what, but nobody was interested. Small potatoes I suppose. Everyone wants the big buck from the big companies. I got kind of discouraged and put it on the back burner until I had more time to get something done over the internet. Luckily enough...in my travels I managed to find a donor unit. Now I just need to take the two to the operating table. Once I get it apart, I plan to take the intact gear and have it duplicated and have a few on the shelf. With any luck I can bring both these blowers back to life and help someone in the future if they have the same issue.

Thanks to everyone for their input on this.

Neil

As mentioned, they almost certainly used that material to reduce gear whine, not pinch pennies.

Since you have a complete gear, it may be possible to take some measurements and have one 3D printed out of plastic. If the loads on the gear aren't too high, there may be a plastic capable of coping. The Edmonton Public Library has a makerspace that should be able to help, if you so choose to try and make a printed plastic gear.

Take trevj's advice and go to Boston Gear or to a Boston Gear seller, like an industrial bearing house. I doubt that any maker of forge blowers made their own gears when they could buy them ready made in just about any size or shape you can imagine.

Look on Ebay, there are phenolic gears for sale.
