Okay fellas, here is my plight I attempted to put my generator belt on today and had quite a tussle, I am trying not to scratch everything up, and am challenged so lifting the generator is one of my problems, but I have a nice engine hoist that I use to help get it in place and lower it down and thighten it up. I loosend the nut that holds the generator bracket to the block, and slid the generator down all the way to give room for the belt to slip up over the top, but it is not low enough to slip the belt over the pulley, it needs to under the crank pulley and around the two waterpumps and on the generator pulley. Any ideas on how I can get this belt back on without killing myself and scratchingeverything up.

I loosened the generator quite a bit and tried to tip in down in the front and slip the belt over the top to no avail, whew I was gettn' frustrated.
I believe the belt is the right one, it's the one that was on it when I took it apart, and one is on, would adjust okay, it's just an initial tight fit.

Is there any trick to this, or I just need another pair of hands with some good strength.
 
Loosen it up real good and put the belt on all the pulley's except the generator or the right water pump. Tilt the generator to the drivers side and slip the belt on. If it is real hard to get the generator up straight you need a longer belt. 30 or more years ago one of the major belt companies screwed up on the length of the belt and this problem has been around for years. take your old belt to a good big hardware or industrial supplier and get a "B" belt the next size larger. There are differant grades of belts, get a good one. Some will say a "B" belt is wrong but don't listen to it. I have several hundreds of thousands of miles on them and a lot of miles at 65 to 75 MPH for 10 or 12 hour runs and never had a belt problem. Tighten to to a 1/2" of total play and check it after about a hundred miles. G.M.
 
I agree with G.M. I have been running a B 51 Gates belt for years on my 40s. I think this belt would also work on your 46 for the generator.
 
A little bit about V-Belts;
B Section V-Belts are industrial grade. They are measured around the inside circumferance in inches. They are made for large pulleys such as in industrial applications. There is also a Minimum pulley diameter associated with the B Section belts.
5L Section belts are known as "fractional horsepower" belts and are measured around the outside circumferance and they can go around very small pulleys. These are easily found in hardware stores. The B Section and the 5L Section are usually found in industrial supply houses like Motion Ind., Applied Industrial and Kaman Industrial.
There is one other that is worth mentioning;
Garden Tractor belts, which are made to go around small pullies and backbend. They are very strong and flexible and I have found them to work where small pulleys are used, such as the ones found on flatheads with alternators. The tension cords are placed in such a manner that they can bend over small pulleys without cracking.
That is probably more than you wanted to know about V-Belts.
