RING - BACK UP (CAT CT1S-0670)

CT1S-0670: A damaged retaining ring can allow a shaft or bore component to shift out of position during operation. The RING - BACK UP, catalog reference CT1S-0670, is an aftermarket replacement part cross-referenced to the OE maker CAT. This type of ring functions as a mechanical stop that holds an assembly in place against axial movement. When a back-up ring fails, the secured component may dislodge, leading to operational noise or binding. Keeping a retaining ring in sound condition helps maintain the intended clearance between assembled parts. Verify the serial number or application, then call (562) 693-7748.
