Frequently Asked Questions
Q: What does the 853326 washer do?
A: The 853326 is a seal-support washer used in hydraulic cylinder mounting assemblies and pump connection points. It prevents fluid leakage past fastener heads and reduces stress concentration on seals during equipment operation.
Q: What material is the 853326 made from?
A: The 853326 is manufactured from hardened alloy steel with a cadmium-free, zinc-plated finish suitable for direct fluid contact in hydraulic systems. The hardened steel resists permanent deformation under sustained hydraulic pressure.
Q: Which pallet jack and forklift models use the 853326?
A: The 853326 is applicable to Crown, Jungheinrich, Linde, and BT material handling equipment with hydraulic lift systems. Confirm your equipment model and hydraulic specification before ordering, as alternative washer types exist for different pressure ratings.
Q: How long is the typical lifespan of the 853326?
A: The 853326 provides 2,000 to 3,500 service hours in standard warehouse conditions. Faster degradation occurs in applications with thermal cycling, high-pressure hydraulic systems exceeding 3,000 PSI, or cold storage below 32 degrees Fahrenheit.
Q: What maintenance does the 853326 require?
A: Inspect the 853326 during hydraulic system pressure tests and after any fluid leak repairs. Look for pitting corrosion, cracking, or fluid seepage around the bolt head. Replace if the surface shows deep pitting or if hydraulic fluid staining appears on adjacent components.
