Ok so I am trying to straighten up things that previous owners have umm, well not quite done correctly. So far it's been simple, but time consuming, adjustments (valves, carburetor, air pressure) Today I replaced damaged petcocks, and near original valve cover and crankcase gaskets (I say near original due to them having been painted over at least twice) and in the process of checking the valve lash or gap discovered two spark plugs just finger tight.

So now you see what I am fighting, here's my head scratcher. Someone converted this tractor ('51 Super C) to 12v, and is running two belts. One from the idler pulley to alternator only, and one runs from the crank pulley to idler, and water pump. The one for the alternator is tight, and seems serviceable but the other one squeals nearly constantly, and the idler / tensioner pulley is at the end of it's stroke.

So do I try to get this all on one belt?? How can I determine or find a better fitting belt to get rid of that squeal?

Thanks for all replies

i would still just use two belts but use i size or two smaller on the one thats at the end of its stroke ( by that im assuming you mean it cant be tightened anymore) jsut take them to your local parts store and tell them what you need should be able to find something i personally like the goodyear gatorback belts seems to be made better and alot quieter than any others ive seen

yeah I was just hoping for a sizing method that did not require the try and fit method. and yes by end of stroke I mean no further adjustment is available.

Goodyear gatorback?? I'll try to find em

Thanks for the tip tractorman!!

not this issue, yet. This is just annoying, other things have been addressed first, like mis-adjusted valves, loose spark plugs, leaking gaskets, mal-adjusted carburetor, and the list keeps growing the more I look. And I haven't even considered cosmetic upgrades yet. I am hoping to get by with a belt swap

you should just be able to tell your parts store just a size or two shorter and you should have plenty of adjusment to go smaller if you cant go any tighter and yes goodyear gatorback and no problem your welcome
