RING - PISTON (Hyster HY0299681)

A damaged piston retaining ring can allow the piston to shift, leading to loss of compression or mechanical binding. The ring seats in a groove to secure the piston pin and maintain assembly alignment. Hyster lists this part under catalog number HY0299681 as an aftermarket replacement. The ring's function is to prevent axial movement of the piston pin within the bore. If the ring fails, the pin may dislodge, causing scoring or seizure of the piston assembly. During a rebuild, technicians often inspect the ring for wear or deformation. Verify the serial number or application, then call (562) 693-7748.
