Product Overview
The fuel shutoff solenoid is part of the engine stop system. A weak coil, sticking plunger, damaged linkage, or failed electrical connection can cause a no-start, intermittent shutdown, or an engine that will not stop normally with the key.
Bobcat officially catalogs 6670776 for the MT55 and identifies 7475471 as its previous part number. The solenoid connects to the engine stop lever; Bobcat specifies terminal 1 as positive and terminal 2 as negative at the harness connector.
Key Features & Performance
- Engine shutdown control: Moves the fuel-control mechanism between run and stop positions on the matching system.
- Repair-focused replacement: Useful when the original solenoid is electrically open, weak, sticking, or physically damaged.
- Fitment-critical electrical part: Voltage, connector/wiring, linkage, mounting pattern, and original part number should be matched before installation.
