International B414 Just rebuilt

The IH B414 almost has me licked. I just got done putting in new rings, honing cylinders and new rod bearings. I did this because of low compression readings and only starting with a shot of ether. I see no improvement whatsoever in the power. It accelerates slow and has no power in the hi range gears. Injection Pump and injectors have been rebuilt so i don't know if i have a fuel issue or what. I have not done a compression recheck yet, maybe i should.

HELP !!!
 
what was the readings before? what about the head? was it rebuilt? need valves in good shape to have good compression also.
 
Dry Compression reading were low 300's. Head looked good, all valves were taken out of head and inspected. They all looked good , not burnt at all. I know i probably should had it rebuilt but i'm on a budget. I keep hearing maybe not enough fuel. Not a air filter problem cuz it has no power even with air filter hooked up
 

I know it was to low that's why i rebuilt it. Injection pump wad pulled off and gone thru and put back on exactly to the mark where it was when i pulled it. Not sure it's right though. I'm not the original owner so who knows what's been done to this engine. I guess i should get a manual on this unless some one can take a pic of the timing instructions from the manual. I sure would appreciate any info or pics on this tractor. It is a 1963 International B414 4 cylinder diesel. BD 154 ENGINE

THANKS
 

(I have one of it's younger brothers, a "424" diesel.)

Is there a free gravity flow of fuel at the injection pump, after the filter?

ASSUMING the intake air system and the exhaust system are not clogged, restricted, full of vermin nests, etc., there's only a couple of things it can be.

Camshaft and/or injection pump timing.

Something wrong with your injection pump, it needs to be looked at by a pro, repaired as needed, and calibrated on a test stand. Have injectors checked, as well.

Or, has that been done?
 
In the last 40 years I have rebuilt over 100 of these BD154 engines and I have
ALLWAYS fitted new pistons, rings and liners so I am certain that is one of your
problems. MJ
 
you cant go by putting it on to exactly where it was. you need a factory timing spec to go by. like who knows , that could have been one of the problems all along as the last guy might have been experimenting.
 

Yep this tractor had been farmerized(jerryrigged) to the max. Brass banjo bolts were all chewed from using vise grips plus other repair jobs like welded up tie rods, brazed holes in the pan. This baby has been worked on alot. The previous owners had no clue what they were doing. Now it's my job to get it all up to snuff. It's been valuable experience for me that's for sure
 
Contrary to popular opinion, if a diesel has enough compression to start and FIRE on all cylinders,
power loss from lack of compression is not all that excessive. I have dyno tested many worn out
engines that smoked as much out of the bottom as exhaust and the power was still not all that bad.

Other issues of timing, worn camshafts, worn out pump, totally messed up injection nozzles , pre
cups, energy cells, poor fuel flow or pressure and air supply are what will kill you on power.
 

Checking injector pump timing to the best of my ability. I have no manual yet to go by so bare with me. I see TDC mark on flywheel and i have side cover off Cav dpa pump. I see letter designations on the rotating doohicky in there. What do they mean? I did rotate the engine one full turn to see another set of letters in the pump. Can someone explain this to me? Pics to follow

Also i see a S1 mark a couple inches away from the TDC mark. What is that for?
 
i see u have it lined up with top dead centre, but those pump marks sure are not lined up.. I am not familiar with this engine but can pick out if something don't look right. you are talking about anther set of letters when rotating. take a picture of those when its on tdc also. usually an E is for exhaust as in the old john deeres.
 

So today i pulled the radiator and hoses to get to the front cover. I wanted to check the timing on the gears in there. I found the idler gear off one tooth when at TDC. Lined it back up correctly and put it all back together. Hopefully it runs a little bit better... waiting now for the battery to charge back up .
Could this be a factory f/up that was done in 1963? It didn't look like it had ever been apart before

here are quite a few letters on that rotating part of the injection pump, i wonder what they mean?
 

Got the injection pump apart again for the third time. I sure don't see anything wrong. Guess I'm gonna have to get it rebuilt professionally along with the injectors. I didn't really want to spend that kind of money.

Wonder what Dieseltech or Al Baker charges to rebuild pumps and injectors. Hopefully once of them will get in touch with me. My email is open

According to the manual at TDC the "E" scribed line mark on the pump rotor should align with the scribed line at the lower hole of the pump snap ring.

What are they talking about? "the scribed lines at the lower hole of the pump snap ring"
