Frequently Asked Questions
Q: What is the function of the DA B153-97 retaining ring?
A: The DA B153-97 retaining ring is a snap ring or lock ring that secures the piston rod and seal stack assembly within the cylinder bore on Dayton model 4YX97 pallet jacks. It prevents axial movement and maintains proper seal alignment.
Q: What happens if a retaining ring fails or becomes loose?
A: A loose or failed retaining ring allows the rod seal assembly to shift out of position, causing hydraulic leakage around the rod, loss of lifting pressure, and potential damage to the seals from misalignment. The jack will lose load-holding capability.
Q: Is the DA B153-97 retaining ring made of steel?
A: Yes, retaining rings are typically manufactured from spring steel and hardened for durability. The DA B153-97 is designed to maintain constant tension and prevent seal stack migration under the cyclic pressures of pallet jack operation.
Q: How do I know if my retaining ring needs replacement?
A: Inspect for visible gaps between the ring and its groove, deformation, cracking, or surface rust. If you observe hydraulic leaks at the rod seal area after other seals have been verified good, a compromised retaining ring may be the cause.
