4. FAQ
Q: Which equipment does this seal kit fit?
A: It is designed for machinery powered by 3304 and 3306 series engines, including excavators, wheel loaders, and other heavy-duty construction equipment.
Q: What materials are included in this kit?
A: It includes seals made of polyurethane, nitrile rubber, fluororubber, PTFE, and a fabric-reinforced wear-resistant sleeve, each tailored for different functions in the cylinder.
Q: What is the main purpose of this seal kit?
A: It prevents hydraulic oil leakage, maintains system pressure, blocks external dust and debris, and protects internal components from contamination and wear.
Q: Can I reuse old seals after disassembling the cylinder?
A: No. Used seals lose elasticity and develop permanent deformation under pressure, heat, and fluid exposure, making them unreliable for reuse.
Q: What happens if the seals in the kit fail?
A: Leakage of hydraulic oil will occur, leading to pressure loss, slow cylinder movement, reduced lifting power, and potential damage to the entire hydraulic system.
Q: What preparations are needed before installing the new seal kit?
A: You need to disassemble the cylinder, thoroughly clean the bore and piston rod, remove all old seal residue and debris, and inspect the rod for scratches or wear.
