John Deere 6910

looking to know where max fuel screw is in John Deere 6910 Lucas Delphi pump electronically operated as previous owner I believe has screwed it and tractor is very smoky so looking it screwed back to normal

There isn't one. You have a mechanical fault if she's unduly smokey, eg split boost pipe etc.

Oh right so there is no screw for reek that all the young lads talk about is there a screw for more power I notice one sitting out Infront of the pump is it a torque screw for more horsepower ? As I am looking some more power aswell just thought the smoke was unusual I need some more power so if there is a screw for that it would be helpn

There also seems like a great decrease in power aswell

You said it has the de10 electronic pump ?

 

[6910baiii]

You said it has the de10 electronic pump ?

Yes it does it’s a Delphi electronically controlled pump

Turbo seized or shaft broken?

 

[6910baiii]

Yes it does it’s a Delphi electronically controlled pump

I thought there was a screw on it for more power and smoke are is it just power

 

[Timbo]

No. The ecu controls fuelling.

 

[6910baiii]

Turbo seized or shaft broken?

I don’t think so it pulls slowly up hills got dynoed before was doing 173 horse and was going well now a big decrease in power turbo boost hose is 100 percent

 

[6910baiii]

No. The ecu controls fuelling.

Is that right for the Delphi pumps I thought it was only the common rails were controlled by the ecu as pump has been done up before and they said they found a screw for horsepower

 

[6910baiii]

No. The ecu controls fuelling.

Now Then..
You have a Lucas / Delphi injection pump which has a little electric motor on the top I assume??
The motor only controls the throttle position. The pump is completely mechanical, as in days of old.
I'd check your fuel system for cleanliness, right from the tank suction screen. Also check the air filter and the hose from the turbocharger to the engine intake..

Is there any screw for more power are smoke ?

 

[Tractortech]

"Power are smoke" ???
Power and smoke ??
Power or smoke??
There are settings within the pump which can be done by fuel injection pump workshops. If you have excessive smoke and no power I'd look at everything else first. Then have the thing on a dynamometer with someone who knows 'stuff' to help...

Ahh right right no no need more power there is a screw on the pump for a power increase I believe?

 

[Tractortech]

No, there is no such user accessible screw.
If there was, everyone would buy small horsepower tractors and turn them up once at home...

Got pump done up and person who done it said they made some adjustments got it dynoed 173 horse great pulling tractor found the problem diesel filter stuffed solid but I don’t understand why there is no black smoke when it’s been opened up even pulling up hills it hardly does out with 12 tonne plus a 3 tonne spreader behind for a 140hp standard it pulls very well but fords have a lot of smoke and I don’t understand why the Deere don’t smoke when it’s been adjusted and in the field it grips as good as a 230 horse tractor we have

Like prior to the filter being stuffed it was roaring for gears in E box up a very steep incline
