AT Z-1105

Frequently Asked Questions

Q: What is the AT Z-1105 washer used for in Atlas Zenith pallet jacks?
A: The AT Z-1105 is an OEM hydraulic component washer for Atlas Zenith Type 9 manual pallet jacks. It serves as a load-distributing spacer and sealing backup component in the hydraulic assembly, positioned at critical interface points to maintain proper component spacing and support seal performance under pressure.

Q: Which Atlas Zenith models use the AT Z-1105?
A: The AT Z-1105 is compatible with Atlas Zenith model manual pallet jacks. It is designed specifically for Zenith Type 9 hydraulic units. The part is not interchangeable with other Atlas models or different equipment brands without dimensional confirmation.

Q: What material is the AT Z-1105 made from?
A: The AT Z-1105 is manufactured to OEM Atlas specifications as a hydraulic component washer. The material is specified plain steel to withstand load-bearing and pressure-sealing applications in manual pump hydraulic systems.

Q: How does the AT Z-1105 differ from other washers?
A: The AT Z-1105 is dimensionally and functionally matched to the Zenith Type 9 hydraulic assembly. It is not a standard metric or SAE washer. Using the correct OEM washer ensures proper component alignment, consistent pressure distribution, and reliable seal performance. Substituting with generic washers can cause leakage and misalignment.

Q: When should the AT Z-1105 be replaced?
A: Replace the AT Z-1105 during hydraulic seal kit installation, when the component shows visible damage or wear, or if leakage is observed at the hydraulic assembly interface. Worn washers lose load-distribution function and can contribute to seal failure in adjacent components.
