Multiquip 2683350103 Valve Exhaust EH12-2D - OEM Replacement Part

The exhaust valve controls the release of combustion gases from the cylinder in the Robin EH12-2D engine, a critical component for maintaining proper engine timing and performance in Multiquip tamping rammers. This valve operates under extreme temperatures and pressures, opening at precise intervals to expel exhaust gases while maintaining cylinder compression during the power stroke.

In the MT-74F and MT-84F rammer series, the EH12-2D engine delivers 4.0 hp maximum output through its air-cooled 4-stroke design with 7.38 cubic inch (121 cm³) piston displacement. The exhaust valve's condition directly affects engine performance, fuel efficiency, and the rammer's ability to maintain its specified 640-680 blows per minute with 3,100 lbs of impact force. Common symptoms of exhaust valve failure include loss of compression, reduced power output, difficulty starting, and excessive fuel consumption.

Compatible with the following Multiquip tamping rammer models:

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