    I have an '85 suburban with it's original 6.2, this oilburner has had a banks turbo on it half it's life...irony is that this beast starts better cold than warm, but other than that runs like a dream.

    b4 attempting any of this make damed sure that the surrounding area is as clean as possible. saw chunks of dirt left in the bowl and thats not going to fly once even a small piece hits an injector. with fuel feed change timing also has to be reset. otherwise there will be a power drop instead of a gain.

    @mattlf9120 5 лет назад +5

    If your pump is newer it should have an irregular polygon(home plate) shaped timing mark cover.
    Remove this cover and rotate the engine until the allen head screw appears.
    Carefully turn this screw clockwise for more juice or counter clockwise for economy.
    Just a 1/2 turn of the screw will allow it to deliver more fuel than your idi can burn unless you have a turbo.

    We always turned it up 1/4turn for the 6.2 diesels with a turbo and no more than 1/8th with non turbo. At any rate, the engine has to be re-timed after the screw is turned. Oh and on one of our 6.2's it didnt run bad at all being 1/4turned with the turbo off, but that was only temporary.

    You can get even more power if you completely remove the limiter.
    You can get about 300 Hp out of a 4911 pump with Turbo.
    But you have to take the distributor head out of the pump, so it's more work.

    Hello, I have been having an issue on my 6.2 where I start it up and it idles ok until I tap thr throttle and it revs up like an extra 500 rpm I first thought this was my throttle cable because it seemed like the cable was sticking. What else could cause this? Faulty high idle solenoid??

  • @keithjurena9319
    @keithjurena9319 7 лет назад +4

    No need to take the top cover off. There is a three screw cover on the side which gives access to the screw. This screw affixes the plunger shoe leaf spring. Tightening it forces the spring flatter, this increases maximum plunger stroke. At other throttle positions, the metering valve controls how much stroke the plungers make.

    I have a Chevrolet Blazer 6.2l 1986.
    So here is my problem:
    When i start the engine,it runs normally for half a minute ,and then the engine turns off,and you can’t start the car for about 15 mins.The cycle is repeating over and over .
    Could it be some problem related with this one(depicted in your video)?

    @133dave133 5 лет назад +3

    That's not a fuel adjustment screw. That's the wire vent, and it has nothing to do with the adjustment of the metering valve. These DB2 pumps all have set fuel values built into them, and the metering valve is always full open at full throttle. There's really no such thing as "turning up" the fuel in these pumps. A person can play around with the min/max governor spring assembly to fatten up the metering valve from idle to 3/4 throttle, but the pump will always run at it's fixed (factory) fuel value at WOT. This is because the high pressure pump and the metering valve is already running at its full capacity (by design) at WOT, and there's no way to increase the stroke (capacity) of this pump or volume of the metering valve in stock form. If you're a broke kid who is just wanting to roll coal on the cheap, just find a way to restrict the air coming into the intake manifold and leave the pump alone because there's no magic screw inside, just pain and misery.

      @daniel kingery, you have to know how a DB2 pump works to realize that there is no way to "turn up" the pump. Timing, is the key. The people that claim to "turn up" is type of pump, are actually just knocking the pump out of calibration. A person could play around with the governor basket weights, or min-max governor, but again, it would be the matter of just knocking the pump out of calibration.

    Why? Without a turbo, all it does is smoke like a bitch....it gives you no more power, and you actually waste fuel, as the black smoke will be unburnt fuel.. also, there is a plate on the side of the pump, under the idle solenoid, you can remove and turn the fuel up.. and clockwise turns it up.. go ahead, those junkers are barely usable when new, it will fry it, if you turn it up.. the 6.5 can be turned up...

      1994 f350 with the 7.3 idi turbo in it one aka one of the best most reliable diesels. It's certainly not the fastest but it's never let me down.

      Maddy Orlesky hahaha and you call a 6.2 a power house? And no the 6.2 and 6.5 engines blow a fat one you can dog a 6.9 7.3 idi or a 7.3 stroke and they'll still out live a 6.2 or 6.5 they're junk end of story.

      Maddy Orlesky I'm not king shit bud I'm just smart and I know how to look at the facts. How many 6.2s and 6.5s are still on the road compared to the 6.9 and 7.3? Much less the 7.3 powerstroke. Face it most of them are in the junk yard because they couldn't even hang in there as long as a gasser would.
