Conestoga Diesel, Junior Moose pump.......

[Yachtcare]

The new pump arrived this afternoon. Already got the injector lines installed. Gonna try to get it on the engine today.

The tag on the pump reads......DB2829-4267 serial xxxxxxxx "Moose Junior"

The number corresponds to an '84-'85 military pump.

So it is clearly not a .31 plunger pump.

The documentation sent with the pump states that a "pyrometer is NOT an option with these pumps" and EGT's must be monitored. "Probes must be within 3" of the exhaust manifold. NO POST TURBO PYRO'S."
So, guess I will have to review the location of my probe in the downpipe.

Also states that "this pump has the potential to melt a piston in your engine, if you floor it and hold it there. The maximum HP this pump is capable of producing can only be achieved if your turbo is intercooled, and your turbo can supply whatever boost is required. That is not to say you will have problems with this pump on a stock turbo IDI. What it means is, that you will and must drive by the pyro, ALWAYS."

So it has clearly had the fuel delivery tweaked.

I figured on adding an ATT later this year.

Add the ATT now, otherwise you're but plugged and will overheat.

Once the pump has been built, all bets are off as to whats inside of it. So it very well could have the .031 plungers, or even larger.

Fermanator beat me to it. without tearing it apart and measuring, no way to know what size plungers are in it. With all the warnings they give you, I would be inclined to think they crammed the biggest plungers they could fit in there.

I was going to look for that thread Will, that is a good price.

I just emailed them yesterday about getting a Full Moose or a Omega Moose. Waiting to hear back. Last time I checked they said they thought a Full was possible and not sure if they could pull of the Omega with a GM DB2. It will be my next investment

keep us posted 6.5l. I tried emailing them about rebuilding my 4911 to moose junior spec. never responded. you might have to call... i cant afford to do it now anyway,so i have not bothered calling.

. . . a "pyrometer is NOT an option with these pumps" and EGT's must be monitored. "Probes must be within 3" of the exhaust manifold. NO POST TURBO PYRO'S." . . . "this pump has the potential to melt a piston in your engine, if you floor it and hold it there. The maximum HP this pump is capable of producing can only be achieved if your turbo is intercooled, and your turbo can supply whatever boost is required. That is not to say you will have problems with this pump on a stock turbo IDI. What it means is, that you will and must drive by the pyro, ALWAYS."

Those types of labels always make me wonder whether they are actually warnings, or dares :hihi:

To the EGT location question, adding it to the manifold (pre-turbo) is straight-forward enough. One of these days I might take the setup to dual EGTS where I run the truck off of the pre-turbo, and shutdown based on the post-turbo.

Got it started up this afternoon. Gotta do some housekeeping and get the rad, etc. buttoned up. Do some timing, and take it for a spin.

ATT has to wait, probably til early fall. New tires are a priority after it hits the road again.

Don't know why I thought the EGT probe was in the downpipe, Its in the crossover below the turbo. Didn't measure how far below, but I think I'll leave it as is for now.

Measure your TPS voltage and see if you are stuck at 4v WOT with a 0.5v idle. I bet they figure the 6.2 pumps are identical to the 6.5 pumps. The throttle shaft rotates about 1v more on a 6.5 pump. I don't clearly recall my WOT voltage on a 6.5 pump anymore as I run 6.2 pumps lately.
