Frequently Asked Questions
What belts run on the BK30x5/8?
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 BK30x5/8 replace the Dodge BK30 X 5/8 sheave?
Yes. Published interchange data crosses the BK30x5/8 directly to the Dodge BK30 X 5/8, as well as Martin BK30 5/8, Gates BK30.5/8, TB Woods BK3058. Verify groove count, diameter, and bore or bushing before ordering.
Why does the BK30x5/8 list two pitch diameters?
Combination sheaves run more than one belt section, and each section rides at a different depth in the groove. The BK30x5/8 has a 2.4 in pitch diameter with A or 4L belts and 2.8 in with B or 5L belts.
Does the BK30x5/8 ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
