Workshop Technical Tip: When installing the drive sprocket onto the new final drive, **always use new bolts and a high-strength thread locker**. Loose sprocket bolts can irreparably damage the final drive hub within a few hours. Tighten the bolts in a "star" pattern using a torque wrench according to the manufacturer's specified torque. Additionally, if you are only replacing one motor, keep in mind that the machine may slightly "drift" to one side due to the performance difference between the new and old units – this can often be corrected by adjusting the hydraulic pump settings.
