Important:

If a clutch is mounted incorrectly then the springs will be run in compression and it will cause the springs to fail.

Generally, most applications that mount directly to the crankshaft use a counter clockwise rotation for standard mount (pulley away from engine). A clockwise rotation is normally used for reverse mounting (pulley towards engine).

In order for your PTO clutch to be installed properly you must torque correctly to prevent premature failure. You must allow both axial and radial free-play on the anti-rotation device. You must allow this free-play or resistance will be created resulting in field bearing failure.

When mounting bolt and retaining washer and torque for the clutch follow these specs. for it to work properly.

  • Use Grade 5 or Grade 8 bolt only

Minimum Torque:

  • 7/16" UNF bolt is 50ftlb/67 Nm
  • 3/8" UNF bolt is 31ftlb/42 Nm
  • M10x1.5 bolt is 35ftlb/48 Nm

Anything less than required mounting torque could result in clutch failure, thus voiding warranty.
