Details

These Stens Electric PTO Clutches are OEM spec and replaces Husqvarna PTO Clutches. They are designed for rugged use and made for residential and commercial applications. These PTO clutches have a One Year Warranty and are maintenance and adjustment free.

You must match up your existing PTO Clutch reference number exactly to the corresponding replacement Electric PTO Clutch. For proper ordering reference Husqvarna, Warner, or Ogura Part No. below in the chart.

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.
