Frequently Asked Questions

What belts run on the BK34x1?

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 BK34x1 replace the Dodge BK34 X 1 sheave?

Yes. Published interchange data crosses the BK34x1 directly to the Dodge BK34 X 1, as well as Martin BK34 1, Gates BK34 1, TB Woods BK341. Verify groove count, diameter, and bore or bushing before ordering.

Why does the BK34x1 list two pitch diameters?

Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK34x1 has a 2.8 in pitch diameter with A or 4L belts and 3.2 in with B or 5L belts.
