Fitment and installation warning: Source reference 10-7-22 does not fit PC200-6 or PC220-6 excavators because the increased recoil-spring diameter causes contact with the roller. Reference 10-7-23 uses the same shell but mounts 5–6 mm farther out from the frame. Do not mix 10-7-22 and 10-7-23 rollers on the same excavator because their mounting heights differ. The source states that 10-7-22 works on machines through the -5 series and that 10-7-23 may be used in complete sets on older series; PC150-5 is also included in this roller change. The source supplier indicated a transition to 10-7-23 only. Confirm the replacement configuration and clearance before ordering.
