Frequently Asked Questions

What belts run on the BK77H?

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 BK77H replace the Dodge BK77QT sheave?

Yes. Published interchange data crosses the BK77H directly to the Dodge BK77QT, as well as Martin BK77-H, Gates BK77QT, TB Woods BK77. Verify groove count, diameter, and bore or bushing before ordering.

What bushing does the BK77H 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 BK77H list two pitch diameters?

Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK77H has a 6.7 in pitch diameter with A or 4L belts and 7.1 in with B or 5L belts.
