Multiquip 15600ZE1003 Oil Filler Cap Assembly

The Multiquip 15600ZE1003 is a genuine OEM Oil Filler Cap Assembly designed for a wide range of Multiquip, Whiteman, Essick, and STOW equipment — including MVC and MVH plate compactors, WM and MC series mixers, QP and CP series pumps, FCG concrete saws, and walk-behind power trowels. As a factory-original component, the part meets the exact specifications set by Multiquip for Honda-powered units across these product families. Sourcing the correct oil filler cap is critical to maintaining a proper engine seal, and this genuine OEM part ensures a direct match to the original fitment. DHS Equipment supplies this part backed by verified part number accuracy so you can order with confidence.

Key Features

• Genuine OEM Sealing Integrity — Factory-original cap material and thread spec maintain a proper crankcase seal, preventing oil contamination and pressure loss in Honda-powered engines across the MVC, MVH, WM, and QP product families.
• Direct-Thread Fit — Machined to the exact thread pitch and cap diameter of the original, this cap seats and torques correctly without modification on all compatible Honda engine applications.
• Broad Cross-Family Compatibility — A single OEM part number covering plate compactors, concrete mixers, mortar mixers, centrifugal and trash pumps, concrete saws, masonry saws, diaphragm pumps, and walk-behind trowels — simplifying parts stocking across your fleet.
• Engine Oil Protection — A correctly seated oil filler cap keeps airborne debris, dust, and moisture out of the crankcase. A failed or missing cap allows contamination that accelerates wear on internal engine components and leads to costly engine damage.
• Verified OEM Part Number — Multiquip part number this part is the manufacturer-assigned reference for this assembly, ensuring you receive the correct cap the first time without guesswork.

The oil filler cap seals the engine's oil fill port, keeping the crankcase closed to the outside environment during operation. It prevents engine oil from escaping through the fill opening while blocking dust, water, and debris from entering — both of which can severely degrade oil quality and accelerate internal engine wear. When an oil filler cap cracks, strips its threads, or goes missing entirely, the engine becomes vulnerable to contamination and oil loss, which can lead to overheating, increased wear, and ultimately engine failure if left unaddressed.
