Need more power out of my VE...But not on a truck

[NWhitney]

Ok so I have a Cummins 5. 9 B series with a VE Bosch pump... . but it is not in a dodge. It is in a 1995 Case IH 1644 Combine. From all I have read it is mostly the same set up as all of the 5. 9's in your trucks. The thing runs great but I need more power out of the motor when I get to some green beans and the motor lugs down. It is turbo'd and aftercooled so I have that much covered. I think what I want to do is just to turn the pump up when there is more boost and maybe have it add fuel sooner when there is an increase of boost. Also I think it is still set at the fartory timing on the fuel pump... what would be advisable to turn it up to?? I am not sure what the advance is factory so I am guessing not that much to start out with so I don't burn the thing like toast. Also does anyone know of a Pyro that I could add to this beast that will reach from the engine to the cab... 12+feet? Thank You for taking the time to read this long thing and please tell me what you think my first move should be.

P. S I do have the injection pump numbers but I don't know which ones are important. If they are helpful let me know and I can get them to you.

Isspro has pyrometers with leads as long as 20' , so you should be able to set one up.

Err... . correction 60' on the lead length

 

[bmoeller]

12' won't be enough. I'd say a minimum of 20'. Would partly depend on how the leads need to run to clear moving parts and other sharp points to prevent rubbing through.

You should be ok turning in the full load stop fuel screw 1-1/2 turn and be ok. Bottom out the afc screw so that when a clump of weeds co throu the roter the pump governer will compansate imedeitly. You don't add boost you get more boost when you add more fuel. You mite say that boost is a by product. More fuel you get more boost with that extra boost you can burn more fuel and so on and so on.

 

[NWhitney]

Paychk, Thanks for the Isspro site I will order one to see what my temps are like so I don't melt the whole thing down.



phillips5, thanks for the pump info... you know way more than me about this pump and that is why I love this site. I am not familiar with these pumps so I will have to do a search to find just how to do what you said but thanks for the help!!

You must have wheat out or tou wouldn't be crossing this bridge this early in the season. Where is bloomingburg Oh.

 

[NWhitney]

Yeah we have about 350 Acres of wheat out and it looks like it could be ready in maybe 3 weeks. Bloomingburg is in Fayette county... . half way between Columbus and Cinnci on 71.



Does anyone know if I should advance the pump timing before I turn up the fuel or just leave it were it is. Thanks

 

[phillips5]

Go ahead and spread the two marks apart 1/16 inch don't go an 1/8 like every body else because I don't know if the industrial engins were timed like the automotive engines. I would think yes but just in case.

 

[phillips5]

what does the engine ID. tag say the horse power and touque is right now .

 

[bmoeller]

It would in the 160-180 HP range. The 1640 is 160 and the 2144 is 180.

If you want more fuel as boost increases then you have two factors to consider.

Do you actually want MORE fuel, or do you want the fueling to come on SOONER.

If your overall fueling supply/volume is ok, then you want it to come on line sooner... to do that you tweak the starwheel downward.

If you want MORE fuel in general then you can rotate the AFC cone for one step in the process, then adjust the fuel screw as the second step in the process..... remember... the full fuel screw sends more fuel across the power band, from just off idle, all the way to the max RPM.

When using the fuel screw method it tends to send a larger portion of the OVERALL FUELING INCREASE to the low/mid range with less of the total increase to the upper end.

I'd choose to work with the AFC cone and the starwheel to begin with ... then tweak from there if you don't see the results...



pb...

 

[NWhitney]

sorry to sound stupid but I am not sure what way I should turn the pump to advance timing... . I am asuming to turn the mark clockwise on the cover(up). I think I will leave the full fuel screw were it is for now and play with the starwheel and then the cone and see what that does. Thanks guys!

 

[Greenleaf]

I think you got it. Turn top of the pump toward the cyl. head.

don't fear the full fuel screw!



don't get crazy w/ it, but put an EGT gauge on it and give it some more fuel. nothing wrong with having more power on tap when/if you need it

Take the CPL number off the motor, it should be on a plate fixed to the front cover on the same side as the injection pump, and call or stop by a Cummins dealer and they will be able to give you all the specs for the stock setup. All the timing, fueling, and boost info should be available with the CPL.

 

[NWhitney]

Ok I think I know which way to turn the pump now... Ordered my EGT Gauge from Geno's and it is on the way. Once that gets here the fun begins!!

 

[NWhitney]

don't know the meaning of wait

Well I said that I was going to wait until my EGT gauge came in but I did not So today I pulled the VE apart and turned my star wheel ALL the way down and then gave the diaphragm a quarter turn. I then engaged the separator and ran the machine from idle to full throttle and it was quick It use to take a few sec for this to happen and now it is instant. Now if the wheat would just hurry up and turn I could test it out for sure. Thanks TDR!

It use to take a few sec for this to happen and now it is instant.

Does that mean the price of wheat will be dropping because the harvesting time will be cut in half?:-laf

The stock timing should be listed on the data plate on the accessory case.

That would have been great to have but this motor does not have that. When I went to cummins to get exhaust manifold gaskets (because on of them was leaking a little and since there is more power I wanted to fix it) they said that the part number was no good to them. The part number was a J I Case number and there was no Cummins part number any were. This engine was a joint venture between Cummins and Case IH and they called themselves Consolidated Diesel Company. So this means that I don't get a nice fancy plate that tells me everything that I want to know and that when I do call Cummins to ask them they don't know... . do you think me Equipment dealer is going to tell me what the timing is... I don't think so So I guess I am going to leave the timing were it is and turn the fuel screw in a little. We ran the combine down the road today and when dad pushed the hydrostatic lever ahead the engine rpms did not drop as far as they did before but he thought there was no more power. Time for the full power screw then
