Belt groove (or section) size for the Emglo KU pump ?

by James Barnes
(Phoenix)

I have an Emglo 1.5 hp compressor with the KU pump. It looks like both the pulley on the pump and electric motor could take a 5/8" (B) belt or a 1/2" (A) belt. On the pump pulley, with a 1/2" belt, there would be only a tiny amount of clearance under the belt, maybe 1/16 or 1/32 ". The motor pulley would have lots of clearance. It came with a B belt.
I wonder if a 1/2 belt would be OK, and if Jenny made it to take either.

If the cost is the same, I'd go with the B belt -

But I think the A belt would be fine in this application. especially if it's much cheaper and/or available.
