Cylinder, Wheel HY3048497
Frequently Asked Questions
Q: What are the bore and rod diameters of wheel cylinder HY 3048497?
A: Wheel cylinder HY 3048497 specifications vary by lift truck model and brake system design. Typical bore sizes range from 2 to 3 inches with rod diameters between 1.25 and 1.75 inches. Verify exact dimensions against your equipment documentation or contact us with your truck serial number for precise specifications and cross-reference information.
Q: Which Hyster lift truck models use wheel cylinder HY 3048497?
A: HY 3048497 fits multiple Hyster lift truck model years and series. It may also cross-reference with Crown, Toyota, Raymond, Yale, Jungheinrich, or Linde equipment with compatible brake geometry and mounting flanges. Always verify bolt hole spacing and port thread sizes before ordering. Provide your truck model and production date for exact fitment confirmation.
Q: What material is wheel cylinder HY 3048497 made from and is it corrosion resistant?
A: Wheel cylinders are typically cast iron or aluminum with internal seals made of nitrile or EPDM rubber. Cast iron versions are more durable in high-pressure hydraulic brake applications; aluminum reduces weight but requires careful hose fitting to avoid corrosion. Most are not inherently corrosion resistant without protective coating. Exposure to salt or moisture accelerates deterioration of cast iron units.
Q: What pressure rating does wheel cylinder HY 3048497 handle?
A: Pressure rating depends on seal type and piston design. Most material handling wheel cylinders operate in the 1000 to 2000 PSI range under peak braking load. Operating beyond rated pressure causes seal failure and brake loss. Never exceed manufacturer specification. Contact us with your truck model for exact pressure limits.
Q: How do I diagnose if wheel cylinder HY 3048497 is failing?
A: Signs of failure include brake fluid leakage at the cylinder base, soft or spongy brake pedal, uneven braking between wheels, and reduced brake response. Internal seal deterioration causes fluid loss inside the wheel hub; external leaks appear as fluid stains on the wheel rim or brake drum. Any of these symptoms requires immediate cylinder replacement for safety.
