Multiquip 2683340103 Valve Intake EH12-2D - OEM Replacement Part

The intake valve controls the air-fuel mixture entering the combustion chamber of the EH12-2D Robin engine, which powers several Multiquip MT-series tamping rammers. This OEM valve is critical for maintaining proper engine performance, compression, and the 680 blows per minute impact rate these rammers are designed to deliver. The EH12-2D engine is an air-cooled 4-stroke gasoline engine with 7.38 cubic inch (121 cm³) piston displacement and 4.0 hp maximum output.

Worn or damaged intake valves cause loss of compression, difficult starting, reduced power output, and inability to reach operating speed necessary to engage the centrifugal clutch on these rammers. Regular valve inspection is essential for maintaining the 3,100 lb impact force and proper travel speed of 29.5-39.4 ft/min. The MT-74F and MT-74FA models use an oil bath lubrication system for the gearbox and spring cylinder, but the engine valvetrain requires separate attention during scheduled maintenance.

This intake valve is compatible with the following Multiquip tamping rammer models:

• MT-74F
• MT-74FA
• MT-84F
• MT-84FA
• MT74FAF
