Comments: This Rexroth drive motor is no longer available. For replacement, determine if machine currently has Rexroth drive motors or Parker drive motors. If the current drive motors are Rexroth, they must both be updated to Parker motors. Purchase update kit #2910328. If the current drive motors are Parker, purchase replacement drive motor #3160263.

Parker motors do not have a removable seal housing at the output shaft.
