JD 350 C won’t shutdown

Pipestem · Jun 30, 2020

Bought this machine last fall. Own old farm tractors
but this is my first crawler. Yesterday after running it
about four hours it wouldn’t shut down when I
turned the key off. Looking for any advice on how I
should proceed in troubleshooting this. All my
tractors just have the pull stop linkage connected to
the injector Pump. Thanks

You should have a shut off solenoid on top of your Injection pump. It requires 12 volts to start the dozer and when it is shut off the solenoid shuts it off. It sounds like your solenoid is stuck on. Pretty easy to check. Take the top off the IP with 3 bolts and pull it straight up. You can reattach the 12 volt wire to it and make sure it is grounded and see if it works.

A sticking shutdown solenoid can be a warning of moisture in the fuel (rust in the pump cover "top" area) or (Stanadyne I.P.) can be a sign of a failed governor damper ring causing particles of steel to be worn off and get grabbed by the magnetism of the solenoid causing it to stick.

If you open it up and find rust in there, take appropriate action to gt the moisture out of the fuel system before it does more $$$ damage, if metal filings the pump needs to come off for repairs before the governor completely fails, overspeeding and possibly destroying the engine.

Some care is required to put the pump cover back on so the linkage engages correctly or damage to the linkage and engine overspeed with no shutdown if the linkage gets bound up when the screws are tightened.
