Frequently Asked Questions
Q: What forklift models does the 4949375A wheel cylinder work with?
A: The 4949375A wheel cylinder is designed for fork lift applications. This is a variant of the 4949375. Confirm your fork lift manufacturer, model designation, and mounting configuration before ordering to ensure correct fitment.
Q: What is the difference between the 4949375 and 4949375A?
A: The 4949375 is for electric lift trucks, while the 4949375A is configured for fork lift duty cycles and pressure requirements. Specifications, bore sizes, and mounting interfaces may differ between the two. Do not substitute without verifying OEM compatibility.
Q: What maintenance do wheel cylinders require?
A: Maintain clean hydraulic fluid at the correct viscosity and change hydraulic fluid on schedule per the manufacturer. Inspect cylinders regularly for external leaks at the rod seal. Monitor brake response and pressure consistency. Replace the cylinder if fluid loss exceeds acceptable limits or braking performance degrades.
Q: What hydraulic fluid does the 4949375A wheel cylinder require?
A: Use the hydraulic fluid grade and type specified in your fork lift service manual. Most hydraulic cylinders operate on ISO VG 46 mineral-based hydraulic oil. Fluid condition directly affects seal life and cylinder performance. Contaminated or incorrect fluid causes premature seal failure.
Q: What seals are used in the 4949375A cylinder?
A: Standard seals are typically nitrile or EPDM elastomers. Rod seals protect against external contamination, while piston seals maintain pressure. Seal material compatibility with your hydraulic fluid is critical. Verify seal type compatibility with your system before operation.
