Frequently Asked Questions

What belts run on the BK34H?

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 BK34H replace the Dodge BK34QT sheave?

Yes. Published interchange data crosses the BK34H directly to the Dodge BK34QT, as well as Martin BK34-H, Gates BK34QT, TB Woods BK34. Verify groove count, diameter, and bore or bushing before ordering.

What bushing does the BK34H use?

A H series QD style bushing, sold separately. H is an industry-standard bushing size, so any manufacturer's standard H bushing fits. Order the bushing bore that matches your shaft diameter.

Why does the BK34H list two pitch diameters?

Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK34H has a 2.8 in pitch diameter with A or 4L belts and 3.2 in with B or 5L belts.
