I installed a 200 AMP Ample Power (Bus) alternator on a Volvo TMD40 instead of putting a Generator on our Kha Shing 36. The Volvo has a 3 Groove Pulley for 3/8" Belts but used only 2 Belts. The Alternator came with a 2 Groove, 1/2" belt Pulley that I used for 2 seasons with the 3/8" Belts but had to Short the Alternator Temperature leads on the Balmar 612 Regulator to limit output to 100 AMPS to keep the belts from self-destructing. I have been unable to find a 3 Groove Pulley for a 5/8" Shaft and 3/8" Belts of about 3 to 4" O.D. in the usual places. Any suggestions?

When I put a 2oo amp altenator on my DD's I couldn't get a sheave either. Went to the graingers catalog found one with the right belt combo and outside diameter with a smaller hole then I needed. Took it to a local machine shop had it bored to the size I wanted and installed it. Works perfect. Bill ----- Original Message ----- From: "Mark G.

Just head down to your local machine shop, they will make one to your exact specs out of billett alumuminum. Make sure you know the profile of the drive pulley, the best bet is to just give them one of the existing belts and they can use that as a guide. Also, you can also use this opportunity to match the RPMs exactly, size the driven pulley so that redline on the engine exactly corresponds with the alternator max rpm. I used this method on Island Eagle to make a custom drive pulley with four grooves, two for each of my 125 amp alternators. Works like a charm.
