CR 116414

Frequently Asked Questions

Q: What components are included in the CR 116414 hydraulic seal kit?
A: The CR 116414 is a complete hydraulic seal kit for electric lift truck jack cylinders. It includes double-lip rod seals, piston seals, wipers, and O-rings. The kit covers bore sizes from 0.75 inch to 2.5 inch and rod sizes from 0.5 inch to 2.0 inch, making it suitable for multiple cylinder configurations on Crown and compatible electric lift truck models.

Q: What materials and fluid compatibility does the CR 116414 seal kit have?
A: The CR 116414 seals are constructed from high-density nitrile rubber, engineered for compatibility with ISO 32 hydraulic oil and DOT3-rated fluids commonly used in electric lift trucks. The nitrile material resists degradation from standard hydraulic oils and maintains seal integrity across typical operating temperatures. Do not use with non-standard fluids or solvents, as this will damage seals.

Q: What are the symptoms of failing jack cylinder seals?
A: Failing seals in jack cylinders cause external hydraulic fluid leakage around the rod or from the cylinder ports, loss of lift pressure, slow or incomplete lift/lower action, and visible oil pooling beneath the jack. Internal seal failure reduces hydraulic efficiency and results in sluggish or erratic cylinder performance. Replacement with the CR 116414 kit is necessary to restore full lift capacity and control.

Q: How should the CR 116414 seal kit be stored before use?
A: The CR 116414 is supplied vacuum-packed to maintain seal integrity and prevent contamination. Store in the original vacuum packaging in a cool, dry environment away from direct sunlight and extreme temperatures. Do not open the package until ready for use. Exposure to air, moisture, and dust before installation will compromise seal performance and reduce lifespan.

Q: What is the expected lifespan of the CR 116414 seal kit?
A: Seal lifespan depends on hydraulic fluid condition, pressure cycles, temperature, and contamination levels. Under normal conditions with proper hydraulic fluid maintenance, the CR 116414 seals typically last 1500 to 3000 operating hours. High-pressure or high-cycle applications shorten lifespan. Replace seals immediately when leakage appears. Maintaining clean hydraulic fluid and following recommended pressure limits extends seal durability.
