Part number 2400178 is a genuine sleeve used in Elite 5500 and PowrLiner 4500/5500 airless sprayers. This precision-machined cylindrical component serves as a bearing surface, spacer, or protective cover for rotating or reciprocating parts such as shafts, pistons, or rods. It reduces friction, maintains proper alignment, and protects mating components from wear. A worn, scored, or damaged sleeve can cause increased friction, misalignment, noise, and premature failure of adjacent parts. This genuine replacement restores proper clearances and reliable operation.

The 2400178 Sleeve is a genuine OEM component designed for Elite 5500 and PowrLiner 4500/5500 airless sprayers. This precision cylindrical component serves multiple critical functions depending on its specific application within the sprayer, including acting as a bearing surface, a wear sleeve, a spacer, or a protective cover for shafts, pistons, or rods.
In rotating or reciprocating assemblies, sleeves provide a replaceable wear surface that protects more expensive components such as shafts or housings from damage. They maintain proper clearances, reduce friction between moving parts, and help ensure smooth, reliable operation. Sleeves may also function as spacers to position components correctly within an assembly or as protective covers to shield sensitive areas from contamination.
This genuine sleeve is manufactured to exact factory specifications for inside and outside diameter, length, material composition, and surface finish. Using the correct sleeve ensures proper fit, optimal performance, and long service life. A worn, scored, or damaged sleeve can lead to increased friction, heat generation, misalignment, noise, and accelerated wear of adjacent components.

When replacing a sleeve, it's good practice to inspect these related components.
Inspect the mating shaft or piston for wear, scoring, or damage. Replace if necessary.
Check adjacent seals for wear or damage. Replace to prevent leaks.
Inspect associated bushings or bearings for wear and replace as needed.
