Multiquip 2685014508 Pulley EH12-2D MT-74F - OEM Replacement Part

The pulley assembly transfers rotational power from the engine's crankshaft to drive the rammer mechanism in Multiquip tamping rammers. This genuine OEM pulley is specifically engineered for the EH12-2D engine series used in MT-74F, MT-74FA, and MT-84F models. When this pulley fails or becomes worn, operators will experience reduced tamping performance, inconsistent blows per minute, or complete loss of ramming action despite the engine running normally.

The MT-74F produces 680 blows per minute at 3,100 lbs of impact force per blow, while the MT-74FA delivers 640-680 blows per minute at the same impact force. The pulley system is critical to maintaining these performance specifications. Regular inspection during maintenance should include checking for pulley wear, cracks, or damage that could affect the automatic centrifugal clutch operation. Signs that replacement is needed include unusual vibration, belt slippage, or visible wear on the pulley grooves.

Compatible with the following Multiquip rammer models:

• MT-74F Tamping Rammer
• MT-74FA Tamping Rammer
• MT-84F Tamping Rammer
