Yanmar fuel shut off???

[vinrum]

I have a older Takeuchi TB35S with a Yanmar 3cyl..I just bought the machine and had it running for about 15 minutes, I tried to move the boom and the motor died..I found that it was real low on hydraulic fluid..After changing the hydraulic fluid, I tried to start if back up and it wont start..I replaced all the fuel lines and fuel filter, and bled the system once again.. At the motor side of the injector line, the fuel is not very strong when turning the motor over.. Also when I had the machine running, I shut the key off and the motor kept running..I cant find a shut off soleniod on the Injector pump..Did these come with a manual shut off??If so, could someone please help me out..The engine is a 3T84HLE

Thanks
Steve

First, if you get air in the lines, it will take a while to get it out. Crack the fuel lines open a touch at the injector end and crank on it until fuel leaks out (beware pressure can pierce your skin and kill you in certain circumstances keep a rag over it). Make sure not to overheat your starter doing this, it will probably take a few tries. When it starts running, it will likely run like dog**** for a while, till the remaining air bleeds through. If it starts while your lines are loose, and you are comfortable with it, snug up the lines. If it freaks you out, run it a little leaking, shut it down and snug em up.

My old Tak has no kill solenoid. It only has a cable shut off, so you move the lever to kill it. This used to be pretty common. If it won't shut off, find the lever at the governor and manually shut it down and adjust the cable properly. Don't ever try to choke it off with a rag or anything. It is dangerous to the engine and you. Not OK on diesels.

Also, just a note, if you run hyd pumps dry they grenade with alarming speed. Try not to run it dry. A plugged hyd filter can starve a pump and the cavitation from the vacuum will eat the pump right up too. I mean if it still works, you are probably ok, just be aware of it.

Oops, I just noticed I read your post wrong.

Something worthy of note whenever you get ANYTHING open ahead of the fuel filter is that you must have NASA style cleanliness. The little ports in the injector tips are EXTREMELY small and almost any speck of dust will plug one up. Usually the symptoms are a rough idle (really rough)

If you are injecting fuel on a direct injection engine it WILL start even if only one cylinder has compression, so have patience and make sure the governor is set to run. If it has glow plugs, make sure they are working (check continuity to ground with the jumper thing off) and use them when you try to start it. You probably have a di engine.

If it is really cold where you are, a hair dryer in the intake may help a lot. Beware of ether that stuff can break an engine in short order or erode pistons over time.
