Frequently Asked Questions
Q: Which Rol-Lift manual pallet jack models does the 40595 seal kit fit?
A: The 40595 seal kit is designed for Rol-Lift T Series and E Series manual pallet jacks with 1-5/8 inch diameter hydraulic cylinders. Cross-references include RL T5BOK, RL T5AOK, RL T5BOK-F-SUPER, and RL T5BOK-H-SUPER. Verify your equipment model and cylinder size match before ordering.
Q: What seals and materials are included in the 40595 kit?
A: The 40595 contains nitrile (Buna-N) hydraulic seals rated Shore A 70±5 durometer, sized for 1-5/8 inch diameter piston rods. The kit includes rod seals, piston seals, and wear rings compatible with standard Rol-Lift cylinder and base plate dimensions.
Q: What is the maximum pressure rating for the 40595 seal kit?
A: The 40595 seal kit is rated for hydraulic system pressures up to 2500 PSI, typical for manual pallet jack pump operation. The kit is also rated for 120 manual lift cycles per hour under standard warehouse duty. Pressures exceeding 2500 PSI or cycle rates above 120/hour may cause accelerated seal wear.
Q: How often should the 40595 seal kit be replaced?
A: Seal kit lifespan depends on usage frequency, hydraulic fluid condition, and operating environment. Under normal warehouse use (50-100 cycles per hour), seal kits typically last 2-4 years before fluid leakage indicates seal replacement is needed. Contaminated hydraulic fluid or heavy use reduces service life significantly.
Q: Are there superseding or equivalent part numbers for the 40595?
A: The 40595 supersedes the RL T5BOK and is equivalent to RL T5BOK-F-SUPER and RL T5AOK. It is also interchangeable with T2.9 series seal kits for compatible Rol-Lift cylinder bore sizes. Confirm OEM part numbers on your equipment documentation before ordering to ensure correct fitment.
