                                                                                  •    - High Thermal Stability: Resists deformation even when hydraulic oil temperatures rise during intensive, 24-hour operations.

                                                                                  •    - Debris Embedding: The specialized material allows microscopic contaminants to embed into the ring, preventing them from scratching the chrome rod or cylinder walls.

Q&A Section

Q1: Is the wear ring replaced every time I replace the seals?

A: Ideally, yes. While the wear ring (07155-01640) doesn't prevent leaks, its thickness is critical. If it wears down, the piston will "tilt," causing the new seals to fail prematurely. It is a low-cost insurance policy for a successful cylinder rebuild.

Q2: Can I use this wear ring in a D375 or D475?

A: No. Large machines like the D375 use larger diameter cylinders. The 07155-01640 is sized specifically for the bore diameters found in the D275 series.

Q3: How do I identify a worn 07155-01640 ring during inspection?

A: Check for flattened areas, uneven thickness, or signs of embedded metal shavings. If the ring is flush with the piston surface or shows signs of charring/burning, it must be replaced.
