Multiquip 18022 Dump Cylinder Seal Kit

The Multiquip 18022 is a genuine OEM Dump Cylinder Seal Kit designed for Whiteman hydraulic power buggies, including the WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WTB-16 series. As a factory-sourced replacement, part 18022 delivers the correct seal dimensions and material grades needed to restore proper hydraulic cylinder operation. This kit is the direct OEM solution for addressing hydraulic fluid leaks or loss of dump cylinder pressure on your power buggy. Sourced through DHS Equipment, you can trust you are receiving an authorized Multiquip component built to original production specifications.

Key Features

• OEM Seal Material Grade — Factory-sourced seals matched to the exact compound and compression rating of the original dump cylinder, ensuring a proper hydraulic seal under working pressure.
• Complete Kit Configuration — Includes all seals required for a full dump cylinder service in a single kit, so the repair can be completed in one pass without sourcing individual components separately.
• Broad WBH and WTB-16 Fitment — Compatible across the WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WTB-16 power buggy models.
• Restores Full Dump Cylinder Function — A worn or failed dump cylinder seal allows hydraulic fluid to bypass, causing the dump bed to lose lift force or drop unexpectedly under load. This kit brings full hydraulic authority back to the dump circuit.
• Hydraulic System Safety — A properly sealed dump cylinder is critical to controlled, predictable bed operation on a loaded buggy. Replacing degraded seals eliminates uncontrolled bed movement that can create hazardous conditions on the pour site.

The dump cylinder on a Whiteman power buggy is the hydraulic actuator responsible for tilting the buggy's hopper to discharge concrete or material. It relies on internal seals to hold hydraulic pressure and control the speed and force of the dumping motion. When these seals degrade or fail, hydraulic fluid bypasses the piston, causing sluggish lifting, incomplete dumping, or an uncontrolled drop of the bed under load — all of which interrupt workflow and can create unsafe conditions. The Multiquip 18022 Dump Cylinder Seal Kit replaces all critical seals in the cylinder, restoring full hydraulic integrity to the dump system.
