Multiquip 03568701 Rubber Diaphragm

The Multiquip 03568701 Rubber Diaphragm is a genuine OEM component designed for MVH-series reversible plate compactors, including the MVH408DZ, MVH308DZ, and MVH508DZ. As a direct OEM replacement, this diaphragm meets the same material and dimensional standards as the part originally installed at the factory, ensuring a proper seal and consistent performance in the field. Sourced directly from Multiquip, part number 03568701 is the correct specification for these heavy-duty reversible compactor models. If your compactor is showing signs of fuel delivery inconsistency or carburetor irregularities, replacing the diaphragm with the correct OEM part is the right first step.

Key Features

• OEM Rubber Compound: — Manufactured to Multiquip's original material specification, delivering the correct flexibility and fuel resistance for sustained carburetor operation on MVH reversible plate compactors.
• Direct Drop-In Replacement: — Matches the original diaphragm profile and mounting dimensions, seating correctly within the carburetor assembly without modification.
• Confirmed Fitment: — Verified for use on the MVH408DZ, MVH308DZ, and MVH508DZ reversible plate compactors.
• Consistent Fuel Metering: — A properly functioning diaphragm maintains accurate fuel delivery under varying load conditions, keeping the compactor running cleanly through demanding compaction cycles.
• Fuel System Integrity: — A cracked or fatigued diaphragm can allow fuel to bypass the metering circuit or introduce air leaks, causing rough running, hard starting, or stalling under load — replacing it promptly restores proper carburetor function.

The rubber diaphragm is a critical flexible membrane inside the carburetor that regulates fuel flow into the engine. It flexes in response to engine vacuum and load demand, controlling how much fuel enters the combustion circuit at any given moment. When the diaphragm hardens, cracks, or loses elasticity — which happens naturally over time with exposure to fuel and heat — the carburetor loses its ability to meter fuel accurately, resulting in poor throttle response, difficult starting, or an engine that surges or stalls under load.
