This is a NEW drive motor to replace Bobcat part numbers 6655435 and 6665396. Both sides use the same drive motor. It is bolted to the gearbox on the chaincase. This is the correct drive motor for all 943 and 953 Bobcats.
*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.*
