More power in a 6748

[sknudsonlineno]

I need to give my 6748 some more fuel . When it starts with coldstart it stops if I dont keep the trottle at full for some sec. I don't think the engine likes that when it's cold. But I don't find the "happy-screw" Ive read about here.

It's getting colder now. Anyone who can tell me how to get just a little black smoke from my 6748? I tried to remove tha backpart of the pump, but that wasn't very easy.

Hi

Have you checked the oil level in the rear section of the pump. It may help it settle down if it is lubricated.

I filled it with oil, I think it helped a little, but I'd still like to give it some more "fuel "

You need to take off the rear hatch of the pump. I'm not sure if its the upper or the 2nd from above screw, and if the old pump internally is the same as the 5245 pump. I never adjusted the 7 series, they all pulled great.

If you really want more power, change the heads for those of a 9 series or newer, they had a bigger intake valve.

Hi if you have problem with less diesel, you can give it more if want ....on front side of fuel pump is cold start key...there are three 24mm
screws if you see ...you must allow middle screww an rotate key for cold start ass allow out for 1/3 - 1/2 wheel ....this step give you more power

Today I had my first testdrive. I think it starts a little easier. It started withoud coldstart in 10C. But the power was a dream. Where I had to use 3. gear before it went easily on 4. now.

Thanks for the advice.
