Yea, nobody ever has any problems with them! :-laf

It's your pump, don't believe me, take your chances. I showed those at the Texas Rally who were interested the pump parts, rack, pin, etc. I am responding for the benefit of those who are trying to learn and otherwise might think everyone concurs with your assessment.

The HP King has spoken, you would be wise to heed his advice!



Joe,

Keep up the good work! Your presence on this board is greatly appreciated.

Ya- I'm sure at 3000 rpm that cap just hops right out of the way!!! LOL!



Someone PROVE ME WRONG!!! Do it with a picture and a real explanation of what is happening. If ya all STILL don't believe me... ... ... ... ..... well... ... ... ..... put your plate back in.



WHEN YOU REMOVE THE PLATE (at least in a 180 pump) ITS PLACE IS TAKEN BY THE CAP... ... PERIOD. YOU WILL NOT GET ANY OTHER AFFECT THAT YOU WOULD NOT GET FROM INCREASING RACK TRAVEL SOME OTHER WAY.



Oh ya... ... ... ..... Bosch designed that thing with the plate in it for a reason. What are any of you doing by putting some other plate in it, eh? That's not the way it was designed to work!! lol again.

T Baker said it the best, drive it with your foot and by paying attention to how much smoke is coming out the tailpipe. The plate is there so that the average joe can just push the "go pedal" and go down the road without thinking about what his truck is doing.

 

[T. Baker]

Radixr and you other guys that keep talking about the ENGINEERS

and all their knowledge need to get a coppy of The Diesel Odesey of Clessie Cummins and see how a guy without an engineering degree built Cummins Engine company from scratch. Later in his life when he built the Jake Brake and he was retired from cummins they turned it down and he had to go to the Jacobs Chuck company to get it built so so much for the finaly authority of the engineer gods you guys keep worshiping!!!

 

[Cummins Corvette]

I am still waiting for someone to prove me wrong. How much money would be lost in the world of diesel dynamics and other vendors if people (with 12v) who are just after power stopped buying plates? I wonder if that has any effect on the opposing arguements.



Hey Joe- it is good that you know the bosch part numbers for the parts of our pumps off the top of your head. That's cool.

 

[Stefan Kondolay]

Maybe some people have better things to do and that's why they aren't bothering to argue with you CC. Not everyone has nothing but time on there hands. I due have a question for you though how much experience due you have with the pumps?



I have a question for those who understand the 12 valve engine (Piers, Joe, Chris Strickland) as my knowledge is limited. Don't the trucks tend to make more power with plates because I know that Piers and some others use them?

 

[smoky]

im with them!!

I am with joe d. , as i am one who will take expieriance in hand and learn from mistakes, so why wouldnt you listen to someone who has been there and is nice enough to try and tell others about there problems, to prevent one from having it happen to them??? no one knows... i know one thing and that is my plate is staying in, and dont see why one would creatE a war over having someone prove them wrong, they ask for peoples advice, they give it and they still go on!!! nobody knowS, i know one thing and that is i really appriciate everyone on this board who give there advice and info on expiriences and all the help that is brought through fromt the members, i also know i would like to have it stay that way, and not pi$$ them off, so they will always be there for you when you are in need.

HATS OFF, AND TWO THUMBS UP JOE D.

 

[T. Baker]

Smokey, I agree about all the great help on this forum. I don't however see a reason why we should not get a better explanation as to why that pin would sheer. I have been in there and looked at it carefully and I don't see how that pin can be sheered. It dosent stop the rack and it has soft springs on each side of it so it can not be forced either way. If the experts say it can be sheered why is is so hard to explain how? Before giving the guys who are expirimenting a hard time go look inside your pump so you can see what we are talking about. I like thease discussions - they are fun and we can all learn somthing here.

Just a thought.

As of knowing when and if the pin will shear... I chose to go by the famous words of Mr. Dirt "How exactly does the posi-trac on a plymouth work?? I don't know, IT JUST DOES!!" If you haven't seen the movie Joe Dirt, you might not get that. I would like to say that, before I joined this website, I knew very little about these trucks, or diesel engines for that. I give my thanks to Joe D. Strick-9, Cooker, illflem, Joe G, and many others. It is people like these that make my 35 bucks well spent. Thanks to these guys and this website, I start school at Texas State Tehcnical School in Sept to give my shot of making Diesel Mechanics a career. As for taking the plate out of your pump, your truck is your truck, if you think it runs better without it, take er outta there. For guys that are satisfied with the aftermarket plates, leave em in there. Everyone drives at thier own risk right?? Well, fine tune your truck at your own risk. If you guys have taken the pump apart and can't see anyway the pin will shear, then get that plate outta there, and enjoy it. For us other guys that like the plate, I look at my plate just like I look at that bolt sitting there in front of my dowel pin, I like the insurance . I will ask Joe D, Cooker, and all the other people that have tons and tons of knowledge to please hang around here on these boards, I never know when I might get stumped under the hood.



Just my . 02

 

[JIM S.]

To all those asking how the pin will shear!!!!!!!!! take the Killer Dowl Pin issue... ... ... there are many trucks out there that have gone many hunderdred thousands of miles and the KDP hasnt budged, but there are many trucks that have lost the pin in less than 100,000 miles!! CC maybe your pin will never shear. . I hope it doesnt! but like others have mentioned, I will leave mine in for the simple sake of insureance... . just the same reason I tabbed my KDP!!!

 

[Joseph Donnelly]

I discussed the pin issue with my Bosch guy this morning. He said that even with a torque plate in the truck, the pin can shear from the force on it during shutdown (rack travel in the other direction), so he always replaces it when doing a rebuild.



I looked at a new 913 and it looked like the rack was stopped by the plug with the pump not turning. However, if that is the case. when the pump is running, there is more going on. He set my zero plate for 20. 8 mm rack travel a couple years ago. I moved the plate around while on the dyno, and found best power at about 2 mm back from that position. So if the plug and not the plate is doing the work, why did I see a power change every time I moved the plate?



I plan to keep my torque plate. However, I am always willing to learn more about these pumps. Lets remember that this is science and engineering, not personal (at least for me).

 

[Brandon]

chris you are just mad because you couldnt afford a plate after your $10,000 B1 turbo... ... ... so you went with the least expensive avenue for fuel plates... .







I didnt care to get in the middle of this but I couldnt resist the temptation

 

[BillGotthelf]

Joe I agree with you, I'll keep my plate. Regarding the plate location are you talking 22-23 mm from the front or rear of the pump?

 

[Joseph Donnelly]

I'm talking about the rack moving forward less than 21 mm, about 19 mm for best power. Many engine configurations may perform better with even less rack travel. Remember that those last few mm of travel correspond to adding fuel very late, when the piston is down the hole.

 

[HEMI®Dart]

Joe,



I read somewhere that the AFC arm or dog has 16mm max travel from the slid forward position. So the most rack travel you can get without modifiying the AFC link is 16mm. Even with a #0 plate is the right position, you still get no more than 16mm rack?

 

[Joseph Donnelly]

Not all afc's are the same. Check your link travel if you want to ensure a lot of rack travel.
