Kubota diesel in TW advice please.

[david]

is it pressurising the sump at all?

[Graham]

Loads of compression. Removed air pipe and tried it and it's not blowing through the oil filler.

 

I just ain't got a clue:confused1:

[Mesterh]

Is it a turbo?

[david]

i take it youv checked how things are in the radiator.

 

check the solinoid that works the stop leaver on the pump is opening up right

 

[Dean Lofthouse]

How many hours has it done Graham ?

[76AR]

i had a similar problem and it turned out to be the automatic stop. when the soleniod is broken it is pushed out and stopsthe fuel flow to th engine.

 

try taking it off...i think mine was two allen key bolts and see if that solves it.

 

hope thats some help

id say it was dirt in an injector holding it open so to much diesel so the thick black smoke may be an idea to get them cleaned and pressure tested

 

had a similar problem at work with a lister twin on a peeler was running fine then stopped changed filter which was blocked up. tried to start it again and all we got was a very thick back smock. injectors have been set away for cleaning and pressure testing.

 

just my thoughts

Thick black smoke is almost guranteedto be unburnt diesel, which would suggest too much diesel, whhich would lesd me to suspect that you may have govenor problems in the injector pump, but usually if the govenor is stuck open then you would just get an engine revving flat out. My knowledge of injector pumps is limited though, and it could be that if the shut off govenor goes that it goes with a large puff of unburnt fuel, so i could be off the mark. Fuel starvation in a diesel produces missing and blue smoke. Can you get it running at all, and if so does te smoke smell of diesel?

are both tyres pumped up to the correct pressure?? clutching at straws here.
