Description

Overview

Fuel Stop Solenoid 12V Thermo King controls fuel shut-off on SB, SL, SLX, TS and Precedent units that use Yanmar engines. When the stop solenoid weakens, the engine may crank without starting, fail to stay running, or refuse to shut down cleanly. This aftermarket replacement suits repairs where you need to restore positive run and stop movement at the fuel control lever.

Features

• 12V fuel shut-off solenoid for Thermo King diesel unit service
• Suits SB, SL, SLX, TS and Precedent model families
• Matches Yanmar 2.49, 3.74, 3.88, 3.95, 4.82, 4.82E, 4.86, 4.86E and 4.86V engine applications
• Replaces a failed stop coil when no-start, no-run or no-shutdown faults point to the solenoid circuit

Specifications and Materials

Fuel Stop Solenoid 12V Thermo King is a 12V replacement stop solenoid for fuel shut-off control on Thermo King diesel units with the listed Yanmar engine families. It suits the common dual-coil shutdown style used to pull the lever during cranking and hold run position afterwards, so correct voltage and linkage travel matter during installation. Part number: TK-42-0100-AM.

See the Woodward solenoid troubleshooting guide for shutdown wiring, coil protection and cranking guidance

Compatibility and Fitment

Match the unit family, engine family, voltage and connector layout before ordering. It suits Thermo King SB, SL, SLX, TS and Precedent units with Yanmar 2.49, 3.74, 3.88, 3.95, 4.82, 4.82E, 4.86, 4.86E and 4.86V engines. Check the solenoid O-ring during service and replace it if it is flattened, cut or heat-hardened. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 40-1900, 401900, 42-0100, 420100, 420-100, 42-100, 42100, 41-9100, 419100, 419-100, 41-4306, 414306, 414-306, 41-6383, 416383, 416-383, 417886, 417-886, 1503ES-12SUC11S, 1503ES12SUC11S, TON-42-100H, TON42100H, 1500-3098, 15003098

Compliance and Safety

Isolate power before fitting the solenoid, then check that the linkage reaches full travel without binding. Because pull-coil heat rises quickly during cranking, avoid long repeated start attempts. Woodward also recommends limiting cranking to three 30-second attempts with two-minute cool-down periods between attempts.

Trailer Applications

Fuel Stop Solenoid 12V Thermo King suits trailer refrigeration repairs where the engine stop solenoid no longer pulls in, will not hold, or does not return cleanly at shutdown. It is also a sensible replacement when fuel shut-off faults trace back to the solenoid rather than the pump, injectors or wiring feed.
