QUICK GUIDE
Use this guide to quickly choose the correct coupling based off the flange diameter and coupling capacity.
STEP 2
Calculate power of coupling required. To calculate power of coupling required use the formula below:
Gearbox Manufacturer and Compatible Couplings
Flange Size
Horsepower / 100 RPM
Formula:
Borg Warner, Twin Disc, ZF-Hurth, Newage, Technodrive 910-001 5 910-004 8 910-014 3 Yanmar (Kanzaki) 910-002 3 910-043 5 Volvo 910-007 (3) 3 910-019 3 910-020 5 910-059 8 Bukh 910-013 3 910-028 5 Paragon 910-005 7 ZF-Hurth V-Drive - Open Center - Adapter Required 910-034 12 910-055 7 910-061 19 Borg Warner, Twin Disc - 4.25" PCD , ZF-Hurth, Yanmar - 4.25" PCD , Newage, Technodrive, Volvo 910-009 13 910-029 20 910-044 8 910-057 25 Yanmar (Kanzaki) - 100mm PCD 910-012 10 Twin Disc - 4.125" PCD 910-036 10 ZF-Hurth V-Drive - Open Center - Adapter Required 910-034 12 910-055 7 910-061 19
Horsepower of Engine Engine Speed (Max RPM)
x Reduction Ratio x 100 = HP/100 RPM
Example:
150 2,500
x 2 x 100 = 12 HP/100 RPM
