Allis 8050 engine build

My 8070 had 4900hrs on the clock when I got it.No gov action below 1500rpm and wouldn't start hot without the bucket of water trick.O/H'd the oil drinker and put an A pump on it with M&W style pistons/sleeves.Fires on first stroke @30deg F.

Calvin, where is the shut off on that pump?

It is a pull to run - push to stop mechanical control.  The diaganol bracket that you see

Well as some may know, I was having trouble with it warming up while working it. I believed the problem to be the new thermostats from agco. I had the old thermostat housing from the 8030 that we had put a intercooler on. Took the newer original thermostats from that and put them in the 8050. Now she runs just like it should. Moral of the story is that these engines need more coolant flow than what the new thermostats from agco can provide. Ones like the old original are from Mr. Gasket 4367 180* Stat.

Just thought id give you guys a update, I've put a good hard 60 hours on her and she has been running great. Finally done with planting, so hopefully I will have time to get it on the dyno before haying.

Interesting thread. Lots of good info and pictures. There's a lot that goes into these diesels to say the least!

Got to reading this thread and realized it was the one from 2 years ago. Had me all excited you was starting another build thread.
Guess all that new marriage stuff took all your time.

So what am I missing here? Why are you tearing it apart again to change the cam and fly wheel? Darrel

And now over a year later, has it been dynoed since the cam grind?
  This was definitely an interesting thread.

I forgot about this thread. Yeah I did redyno it. No more power but it had less boost, So that tells me it's moving more air in and out so less heat. Went from 28 psi of boost to 22-24 psi. So Less restriction. I believe it had more torque on the chopper, but nothing like having a counter balanced crankshaft. Would love to find one and swap it in. Thanks for checking up on me guys!

Somewhat. Still playing with getting the A pump set up just right for my liking.

Ok guys I'm going to update this thread. I never could get the thing to stop smokimg so much. I couldnt figure it out. Started to really piss me off. I emailed Dennis at Fair valley performance this spring and talked to him about it. He recommended I turn the torque capsule in a half turn. If it made any difference I should give it another half turn. Well I did and it didn't make any difference. So now by this time I was really getting pissed. So after 1st crop I took the pump off and injectors out and set them to him. Now before I built the motor, I took this pump to my local diesel shop. K&S fuel injection in weston wi. They said they balanced it and set it to 8070 rpms and to 140cc as I specified, and told them it would be on a farm tractor. Well.... Dennis calls me... pump is way out of wack. High variance between all cylinders, set to around 155ccs and the torque capsule wasn't even doing anything. It was just there for the ride... injectors tested good. So he cleaned them and repoped them to a little higher pressure and reset the pump to the proper specifications. I get it back, put it on and let me tell you WOW! what a totally different tractor! Thus thing not only has the power it did before, but it has some BALLS! Before it would come under load and kinda just slowly die off. It finally has some torque rise now. Lots less smoke. And like I say, TOTALLY DIFFERENT TRACTOR! so in short, never doing business with k&s again.
