Before you start
- Unequal u-joint angles can result in rpm fluctuations and increased wear on the u-joints and pump.
Procedure
- Achieve the best installation when the distance from the PTO U-joint to the hitch equals the distance from the hitch to the pump U-joint.
- For 540 rpm PTO shafts, the distance should be 14 inches [355.6 mm].
- For 1000 rpm 1-3/8" PTO shafts, the distance is 16 inches [406.40 mm].
- For 1-3/4" PTO shafts, the distance is 20 inches [508.00 mm].
Specs & values
- X and Y equal distances maintain equal u-joint angles and prevent fluctuations.
