Yanmar 4JH3 TBE Fuel Shut-Off Solenoid

[moonshine]

Hi there,

Engine will not start, local Engineers suggest that the fuel shut-off solenoid, mounted on the injection pump, is not working and could be cutting off fuel supply.

Has anyone in the forum had a problem with this part and how did you remove it ? I cannot get a ring or open-ended spanner on the hex, only an adjustable with the dipstick pulled out of the way. With the adjustable I cannot get enough leverage to undo the solenoid. I am wondering whether there is a Yanmar special tool required :-(

Any help appreciated.

Cannot see from the picture but could you get a deep socket on it. Or a tube/box spanner.

I've replaced our solenoid on a Yanmar 4JH4E.
It was no effort at all.
Just used a hex socket on an extension on one bolt but the other bolt I had to use a short ring spanner.
(If you don't have a short ring spanner you could take an angle grinder to an existing spanner!)

Let us know if it was the fuel solenoid.
(I would be quite surprised if it was this but you'll soon know once it's off the engine.)
