Frequently Asked Questions
Q: What is the 220028089 housing used for?
A: The 220028089 is an inner pump housing for manual pallet jack hydraulic assemblies. It serves as the primary containment chamber for internal hydraulic pump components and supports safe pressure operation in manual lift truck service.
Q: What is the bore diameter and pressure rating of the 220028089?
A: The 220028089 has an internal bore of 2.50 inches with a tolerance of plus or minus 0.005 inches. The housing is rated for hydraulic pressure up to 3,000 PSI, matching the operating envelope of compatible manual pallet jack pump systems.
Q: What material is the 220028089 housing made from?
A: The 220028089 is machined from cast iron with a black oxide finish. Cast iron provides excellent strength and rigidity for containing high-pressure hydraulic forces while the black oxide coating offers corrosion resistance and a professional appearance.
Q: Is the 220028089 a direct OEM replacement?
A: The 220028089 is an OEM part number with no cross-reference alternatives. It is a direct replacement for manufacturer housing assemblies requiring part 220028089. Always verify bore diameter and pressure rating match your original component before ordering.
Q: What is the expected service life of the 220028089 housing?
A: Cast iron housings in manual pallet jack service typically last the life of the equipment when maintained properly. The 220028089 requires no routine maintenance beyond periodic inspection for cracks or damage and verification of seal integrity at connection points.
Q: What should I check when inspecting the 220028089?
A: Inspect the 220028089 for external cracks, porosity, or damage that could compromise pressure integrity. Verify the bore surface is clean and free from corrosion or debris. Check that all connection points maintain proper seal contact and there are no visible hydraulic leaks.
