Good To Know

Q: Can I install this kit with basic tools? A: Replacing jackshaft and chain case bearings and seals typically calls for pullers or a press along with standard hand tools. Follow your service manual for torque values and assembly order.

Q: Will this kit fit every MXZ X 440 built in these years? A: It is listed for the MXZ X 440 from 2000 through 2006. Because mid-run changes happen, verify against your serial number and parts diagram before ordering.
