Improved Hydraulic Pump Coupler
The 580K's new hydraulic pump coupler gives improved reliability and serviceability with the following features:
□ A larger diameter spline.
□ Larger rubber bushings bonded to the steel spline bushings.
□ Slides back on the pump shaft so that the fan belt can be replaced without removing the pump, for time-saving service.
□ No need for periodic maintenance lubrication.
