Wheel cylinder
Frequently Asked Questions
Q: What forklift models use the 91M46-01100 wheel cylinder?
A: This wheel cylinder is used in electric and internal combustion pallet jacks and lift trucks from Crown, Toyota, Raymond, and similar OEM manufacturers. Confirm your equipment model and production year before ordering, as cylinder specifications differ across product generations.
Q: What is the bore size and stroke of this wheel cylinder?
A: The 91M46-01100 features a specific bore diameter and stroke length designed for precise brake actuation. Verify these dimensions against your equipment manual. Using an incorrectly sized cylinder results in brake imbalance and reduced stopping performance.
Q: What symptoms indicate a wheel cylinder failure?
A: Common failure signs include soft brake pedal, brake fluid leakage around the cylinder rod, brake pulling to one side, or loss of braking pressure during operation. Inspect for corrosion and internal seal damage if equipment has been idle or exposed to moisture.
Q: What type of brake fluid does this cylinder require?
A: The 91M46-01100 is compatible with standard ISO 4414 hydraulic fluid used in most material handling equipment. Do not mix fluid types, as this causes seal degradation and loss of braking function. Refer to your equipment manual for the specific fluid grade.
Q: How often should this wheel cylinder be replaced?
A: Under normal operation, expect 4 to 7 years of service life. High-cycle environments, frequent hard braking, or exposure to corrosive conditions accelerate seal wear. Replace immediately if internal leakage is detected or braking performance degrades.
Q: Are there equivalent part numbers for the 91M46-01100?
A: This part may have OEM equivalents across Crown, Toyota, Raymond, and other manufacturers. If your equipment uses a different part number, we can cross-reference it for you. Provide your lift truck model and serial number for accurate matching.
