Frequently Asked Questions
What belts run on the BK70H?
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 BK70H replace the Dodge BK70QT sheave?
Yes. Published interchange data crosses the BK70H directly to the Dodge BK70QT, as well as Martin BK70-H, Gates BK70QT, TB Woods BK70. Verify groove count, diameter, and bore or bushing before ordering.
What bushing does the BK70H 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 BK70H list two pitch diameters?
Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK70H has a 6 in pitch diameter with A or 4L belts and 6.4 in with B or 5L belts.
Does the BK70H ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
