580ck injection pump question

[Eric a1cnc]

Now that summer is over I am back working on my 580.
I am putting the injection pump back together with a 1 piece weight retainer. There is a larger gap between the Cam ring and the 1 piece weight retainer than there was with the original. The injection pump is a DBGFCC431-30AJ

Is there supposed to be a larger gap?

TIA for any help
Eric

You’ll know if something is wrong if the C-clip won’t close up..
Good luck

Thanks Pump guy,
The c-clip will go on no problem. The original design plates have a recess milled into the back side and it sits nearly touching the cam ring where as the new design leaves 3/32" space. Just looked different and didn't want to put it together wrong

 

[thepumpguysc]

What r u calling “plates”.?
As long as it turns the full throw when the cam ball is in the c ring, your good..

 

[Eric a1cnc]

Maybe a picture will be better

 

[thepumpguysc]

As long as it moves freely when it’s in the housing, you’ll be fine..

 

[thepumpguysc]

That thing looks pitted.!!
What did the head and rotor look like.??
With water erosion like THAT.. your gonna need more parts than a weight retainer.!!!

 

[thepumpguysc]

At an absolute minimum ..
Liner, blades, metering valve, dv and spring..
I’d be real interested in seeing the rotor..

 

[Eric a1cnc]

It got a new liner and blades, The rotor and the rest of the innards were apparently not subject to the water. No signs of pitting on anywhere else. I fully dis-assembled it and the outside was the only pitted spot. Pulled everything out, inspected/ cleaned in an ultrasonic. Metering valve and Delivery valves move free. Pulled out and inspected the bleed wire and cavity. Will be re-sealed with new stanadyne seal kit. Also adjusted the roller dimension. Hopefully I got everything.
I did one last year and it's still running great on my dozer.

 

[thepumpguysc]

FYI.. if the rotor has lines worn in it going around.. chances are it’s not going to crank/start on its own ..
Once it’s started, it’ll probably run fine..

 

[thepumpguysc]

Your cut’n in on my mailbox money son.!!! (Lmao)

 

[Eric a1cnc]

No competition here, Just using what I've learned from you.

Big thank you to you

 

[thepumpguysc]

Lol.. u know I’m kidding right.?
Kudos to u fir using what u learned.
Like I usta say: Stick with me kid, I’ll learn ya sumpin..

 

[thepumpguysc]

Btw.. every pump has its own R/R dimension.. I hope yer not setting them all the same.??
It’ll only be the same if your doing the same pump model number.. (30AJ)

 

[Eric a1cnc]

I do know about the R/R dim being different thanks. So far both have been set for the 30AJ. The first time I put the one together for my dozer I didn't check the setting figuring it was right before. I couldn't get much power out of a newly rebuilt engine. Pulled the pump back off and checked the r/r dim and it was off a mile. Adjusted it to the spec, and WOW it really woke the dozer up.

Oh, I know when I found someone to stick with.. Ur stuck with me now LOL
