55 Fargo Posted March 24, 2008 Report Posted March 24, 2008 Hi all, I may have asked this ? before, but here goes. I have an engine that is a later modsel 1951, the waterpump and crank pulleys are the narrrow type. The generator is the wide pulley type. My question is this, will this cause the belt to slip, and/or squeak, and possibly wear out faster? I tried this on the bench with the narrow belt in the wide pulley on the genny, hold it tightly it slips easily, on the fan pulley holding it tightly, it does not slip. I suspect this could cause squealing at higher engine rpm, and possibly slipping, which might even keep the waterpump from pumpimg as well as it should at higher rpm. Just a thought, have any of you had this combo before or now, will the different pulley sizes cause a belt slippage problem, especially at higher rpm? Thanx Fred Quote
Norm's Coupe Posted March 24, 2008 Report Posted March 24, 2008 Fred, Thats not a good test. You can't hold that by hand and keep it tight enough. In order to test that setup on the bench you would have to mount the generator and fan to the bench with an adjustable bracket. Everything would have to be bolted down, or in a vise so it can't move when started. Quote
Lou Earle Posted March 24, 2008 Report Posted March 24, 2008 most any generator/starter shop has and can install anarrow pully on the generator. i probably have one if you cannot find one on a generator Quote
Captain Neon Posted March 24, 2008 Report Posted March 24, 2008 I'd just install a 6 volt alternator and be done with it. They come standard with a narrow pulley. Quote
Plymouthy Adams Posted March 24, 2008 Report Posted March 24, 2008 In answer to your question, odds are the v-belt will bottom out on the wider pulley causing the belt to distort and eventually roll in the groove...the belt is designed to ride just off bottom in the V-groove Quote
55 Fargo Posted March 24, 2008 Author Report Posted March 24, 2008 Bingo!!! Tim, this is what happened last summer, my belt which wasn't that old started to roll itself insdie out and fall off the pulleys. Having this one wide pulley cannot be good, I bet at high rpm it slips, causing problems................Fred Quote
55 Fargo Posted March 24, 2008 Author Report Posted March 24, 2008 Yes I may do this, I did find one shop in Winnipeg City, they have been around since the 50s, the young guy working there for his great-uncle, said they have about 6 old mopar gennys on the shelf in the back, still in boxes and new. I am going there as soon as I get a chance to have a looksee...............Fred Quote
