RING SET - STANDARD - 1 PISTON (Hyster HY13709)

HY13709: A damaged retaining ring can allow a piston to shift, leading to loss of compression or mechanical noise. During disassembly, a retaining ring may appear intact but still fail under load. Keeping a retaining ring in sound condition helps maintain piston position within its bore. This aftermarket replacement part references Hyster as the OE maker and carries the cross-reference number HY13709. The ring set is standard for one piston and functions as a mechanical fastener to secure the piston assembly. A worn or missing retaining ring can cause the piston to dislodge, resulting in sudden power loss or internal damage. Verify the serial number or application, then call (562) 693-7748.
