Subject: Seam Clamp Pin Retainer



The current seam clamp pivot pin retaining ring must be replaced.

PMC part #HW-10970 (MFG #5100-37 Truarc) must be replaced using PMC part #HW-10944 (MGF #WSM-37, manufactured by Smalley, www.smalley.com).

PMC has had several reports of failures of current retaining ring. This is attributed to fatigue, overextension, and/or re-use.

All snap rings are designed for one-time use.

PMC is currently evaluating the design on the 1002 models. We ask you to replace the current item immediately to avoid any future component damage.
