Frequently Asked Questions
Q: What components are included in this seal kit?
A: The RL T5BOK kit contains all seals and O-rings for a complete Rol-Lift Series E hydraulic rebuild, including ram seal, rod wiper, pump plunger seals, valve O-rings, and washers. Replacing them all ensures the hydraulic unit is fully resealed and leak-free.
Q: What hydraulic cylinder size is this seal kit designed for?
A: Fits Rol-Lift Series E pallet jacks with a 1-5/8″ (1.625″) ram diameter. Not compatible with smaller Series T models. Measuring your ram ensures correct fitment and prevents installation issues caused by incorrect seal sizing.
Q: Should I replace all seals at once or only the one that is leaking?
A: Replace all seals at once. They age and wear together, so doing them all avoids repeated disassembly and reassembly. The complete kit ensures every seal is new, restoring performance and reducing the risk of another leak soon after.
Q: Does this seal kit come with installation instructions?
A: No printed instructions are included, but placement matches OEM diagrams. You can use the Rol-Lift service manual or contact Pallet Jackson for guidance to ensure seals are installed correctly and in proper orientation.
Q: Are the seals in this kit of the same quality as the original OEM seals?
A: Yes, they are equal or superior in quality, made from high-grade materials by reputable hydraulic component manufacturers. Properly installed, they offer OEM-level performance, longevity, and leak-free operation.
Q: How long should these new seals last once installed?
A: With normal use, they can last 5+ years, often longer in low-use environments. Lifespan depends on usage, load weights, and conditions, but quality materials ensure durability and long-term leak prevention.
Q: What is the difference between this standard seal kit and the “Super” seal kit (RL T5BOK-F-Super)?
A: The “Super” kit fits certain updated or alternate Series E hydraulic units, often with different main seal styles. Use RL T5BOK for standard units unless your model is specifically marked as “Super” or requires alternate parts.
