RING - PISTON (JCB JC04/600135)

A damaged retaining ring can allow a piston to shift, leading to loss of compression or mechanical seizure. During assembly, a retaining ring must seat fully in its groove to secure the piston pin. Keeping a retaining ring in sound condition helps prevent pin walk and internal contact. This aftermarket replacement part references JCB as the OE maker and cross-references part number JC04/600135. The ring's plain mechanical function is to hold the piston pin in place within the piston bore. A concrete generic failure consequence is that a broken or missing ring can cause the pin to score the cylinder wall. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.012 POUNDS.
