Frequently Asked Questions
Q: What is the bore size and piston type of the 5916113681 wheel cylinder?
A: The 5916113681 features a 1.875 inch bore diameter with dual-action aluminum pistons and dual seal cups for balanced braking pressure. Internal spring design allows automatic retraction when brake pressure is released.
Q: What forklift equipment types does the 5916113681 fit?
A: This wheel cylinder is designed for rough-terrain and outdoor forklifts from Raymond, Hyster, and Jungheinrich with capacity ratings 6,000 to 12,000 pounds. Verify brake circuit pressure and axle load rating match your equipment specifications.
Q: What seal materials are used and what is their lifespan?
A: The 5916113681 uses premium NBR (nitrile) cup seals rated for continuous temperatures to 160 degrees Fahrenheit and mineral-based hydraulic fluid. Seals typically function 1,800 to 2,800 service hours before leakage occurs due to hardening or wear.
Q: What common problems occur with this wheel cylinder?
A: Brake fluid leakage past piston seals, reduced braking force from contaminated fluid, sluggish brake response from internal corrosion, and asymmetric pressure between dual pistons indicate wear or failure. Water contamination in hydraulic fluid accelerates seal degradation.
Q: What are equivalent or cross-reference part numbers?
A: The 5916113681 is equivalent to Hyster 1382149, Jungheinrich 50027410, and Raymond 4366-020. Confirm your equipment model year and brake system design before ordering to ensure proper fitment and pressure rating compatibility.
