Strangely B 52 also fits a 261 Chev engine.....

Due to manufacturing differences and then pulley modifications to match groove size and substitution of a smaller pulley alternator for the original generator..... this is what I have opted for...... works every time.

I purchased a 6 foot lenght of special linked belt in 1/2 inch size. These are usually available in wood working store.... claims it will reduce vibration on table saws and other motor driven tools. Each link can be dismanteld with needle nose pliers and adjusted for lenght by the inch.

You simply fabricate the proper lenght that will fit your engine set up.... take it apart and run to the nearest tractor dealer to match the size and proper width..........

Also comes in handy when you need to replace a fan belt on a old Allis Chalmers tractor that requires removing the rad hose ( and draining the rad).
You simply assemble the links with the belt in place.

Caution.... it sells for about 9$ a foot but can be reused over and over again.
