Frequently Asked Questions
Q: What type of packing is included in the SY41173 kit?
A: The SY41173 packing kit contains static and dynamic seals designed for hydraulic and pneumatic applications in material handling equipment. The kit includes O-rings, packing rings, and gasket materials manufactured to resist mineral oil and standard hydraulic fluid exposure.
Q: What equipment or assemblies use the SY41173 packing kit?
A: The SY41173 is used in hydraulic manifolds, valve blocks, pump housings, and cylinder rod glands on electric pallet jacks and powered platform trucks from manufacturers including Crown, Toyota, Raymond, and Yale. Verify the specific manifold or assembly location before ordering.
Q: What materials are the seals in the SY41173 kit composed of?
A: The SY41173 kit features nitrile elastomer seals and polyurethane backup rings rated for ISO VG 32 and 46 hydraulic fluids. The material composition provides low-temperature flexibility in cold storage environments and high-temperature resistance in standard warehouse conditions.
Q: When should the SY41173 packing kit be replaced?
A: Replace packing immediately upon detection of external leaks from the manifold, valve block, or cylinder rod. Do not attempt to tighten or repack leaking seals as continued operation under pressure will damage seating surfaces. Replace all kit components as an assembly to ensure uniform material compatibility.
Q: What pressure and temperature ratings apply to the SY41173 kit?
A: The SY41173 seals are rated for system pressures up to 3000 PSI and operating temperatures from minus 20 to plus 100 degrees Fahrenheit. Do not use this kit in high-pressure or high-temperature applications exceeding these specifications as seal failure and system leakage will result.
Q: What is the typical service life of the SY41173 packing kit after replacement?
A: After proper installation, the SY41173 packing kit typically provides 2 to 4 years of leak-free sealing under normal duty conditions. Service life is shortened by high operating pressures, contaminated hydraulic fluid, or extended idle periods. Replace contaminated fluid immediately after packing replacement to prevent premature seal failure.
