Looking for a Hustler 606936K PTO clutch? This part-number guide connects the 606936K and 603336K replacement references, identifies the related Warner 5228-87 and Xtreme X0809 paths, and shows what to check before ordering for a Super Z or Super Z HD commercial mower.
606936K vs 603336K: what is the replacement path?
606936K and 603336K appear together in Xtreme's application coverage for its X0809 replacement. Warner lists its 5228-87 clutch as replacing earlier 5228-57, 5228-14 and 5228-71 references. Warner's older 5228-57 information identifies 603336K. This is a useful cross-reference trail, though the number on your own clutch and the machine-specific parts information remain the checks to use for your mower.
- Hustler replacement references: 606936K, 603336K
- Warner reference: 5228-87
- Xtreme aftermarket reference: X0809
The unit sold by PTO Direct USA is an aftermarket replacement, not a Warner or Xtreme branded clutch. These numbers identify application paths for comparison.

Check these clutch details before you buy
- Read the original label: look for a Hustler, Warner or other manufacturer part number on the old clutch
- Check the crankshaft: this replacement is listed for a 1-1/8 inch (1.125 inch) bore
- Compare the pulley: check the nominal 7-1/4 inch diameter, belt groove and pulley offset
- Confirm rotation and mounting: clockwise rotation and reverse-mount configuration must match
- Compare wiring and restraint: inspect the connector, lead and anti-rotation arrangement in the product photos
Measurement reference: Warner publishes a 7.24 inch pulley/flange outside diameter for 5228-87. Our aftermarket unit is listed at approximately 7-1/4 inches nominal. Compare the full configuration rather than selecting by a rounded diameter alone. Warner's electrical and torque ratings describe Warner's own clutch; they are not specifications claimed for the aftermarket unit on this page.
