The Multiquip EM16477 is a genuine OEM Hydraulic Oil Tank Cap designed for Whiteman power buggies and Mayco concrete pump models including WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, WBH21EPA, WPB16, WPB16E, LS-40, LS40TD, LS50TD, and LS60TD. As a direct Multiquip OEM component, the part is manufactured to the same specification as the original cap fitted at the factory, ensuring a correct seal on the hydraulic oil tank. Sourced and stocked by DHS Equipment, this part ships as a verified OEM replacement so you can get your machine back to work with confidence.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Multiquip OEM specification, this cap delivers the correct compression fit and seal material grade needed to maintain hydraulic system pressure and prevent contamination.
- Direct Tank Port Fit — Threads directly onto the hydraulic oil tank filler neck with no adaptation, matching the original cap geometry and thread pitch of the EM16477 application.
- Broad Fitment Coverage — Compatible with a wide range of Whiteman power buggy models (WBH-16, WBH-21, WPB16 series) and Mayco concrete pump models (LS-40, LS40TD, LS50TD, LS60TD).
- Contamination Defense — A properly sealing hydraulic tank cap keeps moisture, debris, and airborne particles out of the hydraulic fluid, protecting pumps, cylinders, and valves from accelerated wear.
- Hydraulic System Safety — A failed or missing tank cap can allow hydraulic fluid to escape under pressure or during operation, creating a slip hazard and potential system damage — replacing it promptly is essential.
The hydraulic oil tank cap seals the filler port on the hydraulic fluid reservoir, preventing fluid loss and keeping contaminants from entering the system. On power buggies and hydraulic concrete pumps, clean hydraulic fluid is critical — even small amounts of dirt or moisture introduced through an unsealed tank can degrade fluid viscosity, damage seals, and cause pump failure over time. A worn, cracked, or missing cap should be replaced immediately to maintain the integrity of the hydraulic circuit and avoid costly downstream repairs.
