Frequently Asked Questions

What belts run on the BK140x3/4?

4L, 5L, A, and B section V-belts. These sections are standardized, so any manufacturer's belts of the correct section and length will run in the grooves.

Does the BK140x3/4 replace the Dodge BK140 X 3/4 sheave?

Yes. Published interchange data crosses the BK140x3/4 directly to the Dodge BK140 X 3/4, as well as Martin BK140 3/4, Gates BK140.3/4, TB Woods BK14034. Verify groove count, diameter, and bore or bushing before ordering.

Why does the BK140x3/4 list two pitch diameters?

Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK140x3/4 has a 13 in pitch diameter with A or 4L belts and 13.4 in with B or 5L belts.
