STEP 3
Select part number that closest matches your HP / 100 RPM dictated in Step 2. * HP / 100 RPM cannot exceed max. Example: Using the example, there are four options for a ZF Hurth 45A with a 5” flange, the 910-009, 910-029, 910-044 or 910-057. Based on our 12 HP/100 RPM the best option would be 910-009 that is rated for 13 HP/100 RPM.
O - These couplings are fitted with a shouldered bush to locate in the gearbox flange. O - These flexible couplings have been approved by Bureau Veritas. X - These flexible couplings have been approved by Lloyds Register of Shipping. # - For the Hurth HBW 150 V Gearbox an adapter 202-351 is required (0.875" long). - Open center flexible couplings
