In Reply to: Belt pulley thoughts posted by Mike CA on October 24, 2009 at 22:09:56:
The first obvious question, Mike, is what kind of shape is yours in?
I'll admit that when I started working on tractors instead of working on and around them was to learn that the core of the pulley on your tractor is paper. I'd seen the one on Grandpa's H and always thought it was a turned piece of wood. It was a shedded tractor, never left for more than a few days out in the weather but the shed idn't have doors either. By the time I came along, it was probably fifteen years since the tractor had been belted up to anything, but it still had a glaze and sheen to the surface of it. I know nothing of what goes into them, but expect that it's a mix of hard, tacky waxes or resins that will shine but be tacky as they warm up. Some of that may have been a residue from a belt dressing that worked its way into the fiber.
So the next question is whether you have some evidence of that and then what physical shape your pulley has. You've seen the metal pulleys. If your paper pulley still has something of the ridge/dome in the middle, you may not have to do anything. That's all you need to get a wide belt to ride properly on it.
If it's crumbling or no lnoger has a dome or, worse yet, is recessed inside the ends, then it would be time to see about having it redone or trading in the core, however those folks do things.
If it still has that dome/ridge shape, I'd suggest you develop some contacts with some of the guys at the tractor shows and see if you can't arrange to get to a show and belt up to something, a buzz saw, a hay press, or (my dream) a thresher . . . Bring your own can of belt dressing, but let the fellow who owns the belt apply it. If yours is at all dry, it will soak up any excess but, more importantly, with the heat of working, will seal up and glaze over to protect it from deteriorating.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
