I have two generators, one with the wide belt and one with the narrow belt. My engine is a 1950 8BA whose crankshaft pulley is wide, so obviously I want to use the matching generator. However, it has a cast pulley which has a crack in it. The crack looks old, but I don't want that thing flying apart and gumming up the whole thing! Is it safe to run it that way? Would it be better to swap out the pulley on the narrow one for a wide pulley...and if so, what's the best way to get that ramfangled nut loose on the front? The wide belt one looks pressed on, unfortunately. Thoughts?
I broke the cast pulley on my 28 chevy generator...so I ground the broke edges, and brazed it back together. An impact wrench (air or electric) will usually pop the nut right off.
i would not use the cracked one.....period! impact gun will take the nut off. are those pulleys hard to find?
I took a break and went out to the shop and was able to get he cracked pulley off after taking off the housing and putting the core in a vice...not too tight, though. The pulley unscrewed right off! Now to find a new one....it just threads right on the shaft, no nut or anything. I tried to do the same with the narrow belt generator with the nut holding on the pulley, but no banana. I'll try and fix this other one first. No idea where to get these pulleys though!
There's the pulley that was on it. I think it was missing the C clip on the shaft. Here's the back: Sent from my iPhone using The H.A.M.B. mobile app
Should be able to find the whole generator for a few bucks at a flea market. The big on line auction site should have them too.
$40.....WHOA!!!!!! That's plum crazy talk..... http://www.macsautoparts.com/ford_mercury_early/generator-pulley-3-18-od-single-pulley-v8-ford.html
If you look at the first image I posted above, you'll see it on the lower right hand corner of the image. It starts at the rim and goes about halfway into the V notch where the 5/8" belt seats.
You really think so? Somebody had to make a pattern, then a core box, then cast it, then machine it. Then, somebody built a building, added shelving, paid property taxes, utilities and insurance. Then they hired people to fill orders and ship stuff. All so someone else could buy one of these if they needed it. Seems like a pretty decent deal to me. Ray
Seeing it was all likely made in China to begin with, yeah, I think it's a bit steep. If it was all made in America, then that price would sound feasible. It'll be cheaper to wait around for a swap meet special. Mac's can keep their part, and continue to pay their property taxes with credit, me thinks.
Go on the Ford Barn. Or put an ad on here in the wanted. I've sold whole generators for $40, and they are real. Also not that hard to find a pully already off. I don't currently have any myself. I also would not use the cracked one. Good luck.
I have no dog in this fight, so it matters not to me which path you choose. If there is no rush in getting the pulley, if you do not count fuel to travel to the swap meet, etc., then yeah, it might be a better place to look. But people tend to to ignore/deny 'transaction costs'.... those incidental expenses directly tied to reaching their goal. My point is that it costs money, lots of it, to have shelves full of parts waiting for someone who wants to buy them. The people who do that do, of course, expect to make a profit from their investment. And rightly so. They are performing a valuable service to their customers, whether we are talking fork lifts, hay balers, hot rods or washing machines. Even if we choose to search for a more economical solution, and I often do, in my opinion we still owe some respect to those who attempt to serve our needs. Ray
A repop pulley cost me a radiator and some motor life , I'd only run a good one , but check the price on a 39 standard gen pulley... Then get back to us on how you feel about 40 bucks!
Would bother me to use it, would have to be repaired and with strength, not just braising. But thats just my opinion. I once had a 1969 ford 1 ton truck with a 390. One morning I started the truck to leave for work, it was running rough and had a strange vibration in the engine. I was leaning over the fender and gave a couple quick pulls on the throttle to see if it would clear up. A fan blade came loose, and buried itself in the inner fender, just a few inches from my chest. Coulda woulda shoulda killed me right there. I would change it, it might not get you, but it might come loose and hit your child playing in the yard. I consider it a safety issue, you are responsible for it to be safe.
Over on the Ford Barn you might contact Mac VP. He owns Vanpelt Sales. Email address; www.vanpeltsales.com/. He might have what you need, or might know where to find it. Bill
