This is a brand NEW hydraulic wheel drive motor used on Bobcat models 540, 542, 542B, 543, 641, 642, 642B, and 643. This motor is not packaged in a Bobcat box and has not been bought from Bobcat, however it is exactly identical to the unit you would buy from Bobcat, same make and model. It replaces Bobcat part number 6630037.

It has a 1 1/4 inch diameter 14 spline shaft,and #10 O-ring Boss ports. The older machines originally had a tapered keyed drive shaft, that motor is also available for the same price if you do not want to spend the extra money required to buy new sprockets. I also sell the parts for this motor if you do not need to replace the whole thing.

This motor is originally used on the following models:
540, 542, 543 serial number info not available
542B this is the only motor used
641 after serial number 13346
642 after serial number 13346
643 after serial number 13620
642B this is the only motor used

If you have an earlier machine with a tapered shaft, you will need a hydraulic motor to replace Bobcat part number 6599718.

The earlier machines can use this motor if the sprocket is changed, it is best to look at the shaft before ordering to be sure no one has ever changed it over.

*Since drive motors are installed new by the OEM in pairs. Loader Parts Source, Inc. always recommends changing both drive motors as they have been exposed to the same wear and tear. This could save future down time and expense.*
