Diesel injector pump timming

TinCan · Oct 13, 2017

I have a to believe is a, I call it a '63 Diesel 4000. I call it a '63 because the serial # are gone because of battery acid. It's a '62-64, so I picked a '63.

I am going to pull the injector pump off to do some fixing, cleaning, and painting, and I don't want to paint it blue with the rest.

I have brought the piston to 18degs before TDC and the pump does not quite match up. I wrote down the numbers, and I have a 172, but the pump numbers are , CONN9 A543-H. The Ford Tractors shop manual say's that is for a 144 engine, and set @ 23 degs.

I am confused. Do I time it at 23, or 18.

Wear on crank,cam, and injection pump drivegear will throw timing off some. Dont forget to check or replace the hex oil pump driveshaft between the oil pump and injection pump. You can get a good idea of year by Ford casting number codes on every part. Keep it CLEAN. I use starting fluid to clean all open lines. You might want to do the injection pump driveshaft seals if youre taking it off.

Pull the side cover off the pump.. little window w/ 2 flat head screws..
Rotate the engine over until the lines line up.. one is stationary & 1 rotates.
When the lines are lined up.. CHECK to see what degree your at..
That will ensure your on # 1 compression anyway.
Good luck..
