WASHER
Frequently Asked Questions
Q: What is a washer and what purpose does it serve in a pallet jack?
A: A washer is a flat or shaped metal component placed under bolt heads or fasteners to distribute load, prevent fastener loosening, and protect component surfaces. In hydraulic assemblies, washers maintain proper spacing, pressure distribution, and seal compression.
Q: Is the EC PAL-P62-12017 washer specific to Ecoa PAL models?
A: The EC PAL-P62-12017 is designed for use in Ecoa brand pallet jacks, including the PAL model line. This washer is used in assembly locations where load distribution and proper fastener tension are critical to hydraulic system integrity.
Q: What material is the EC PAL-P62-12017 washer manufactured from?
A: Ecoa washers are typically made from cold-rolled steel with a zinc or nickel plating to resist corrosion and oxidation. Material selection ensures adequate strength to support fastener preload and maintain seal compression in hydraulic assemblies.
Q: When should washers be replaced on pallet jacks?
A: Washers should be replaced whenever fasteners are removed from pump or cylinder assemblies, as reuse of compressed washers may not provide adequate load distribution and seal compression. Damaged, deformed, or severely corroded washers must be replaced during any hydraulic system overhaul.
Q: Can I use the same washer specification across different Ecoa equipment?
A: Not necessarily. Washer size and thickness vary based on fastener size, pressure class, and assembly location. The EC PAL-P62-12017 is specific to Ecoa PAL model pallet jacks. Using incorrect washers may prevent proper seal compression and cause hydraulic leakage.
