Thanks to all who have given me advice when I needed it. But now again I need help.
As I've stated in other topics, I'm helping a friend, who rescued a 1066 with a 1466 engine, from the scrap yard. It was in a fire, so we cut the cab off, cleaned and painted the tractor. I re wired it, and we overhauled the motor.
I've been trying to figure out why the darn thing won't start, and I'm sure it has something to do with the injector pump.
When I had the motor apart, I marked all the gears that need to be timed up, so I know I did that right.
Being that the fire may have damaged the original injector pump, I bought a used one, that the person who I bought it from, said it was a good pump.
With the engine on TDC at O degrees, In installed the pump, making sure the mark on the pump gear, lined up with the pointer on the pump.
I've pumped the fuel up to the injectors, and thought it was ready to go.
It won't fire!
I know I have to have the throttle ahead a bit, to feed fuel to the pump.
When it cranks over, smoke does come out of the exhaust pipe, but it wont start up.
I talked to a friend of mine, and he said that maybe the pump was 180 degrees out. So from what I read in the engine manual under the injection pump, it explained the pump had to turn twice, to completely get fuel to the injectors. So it turns the same speed as the crankshaft.
Instead of removing the 3 bolts from the injector gear, and turning it 1 turn, per the book, I pulled it out, and rotated it 1 turn, and re installed it.
After making sure I had fuel to the injectors, I tightened down the lines, and tried starting. It is doing the same thing, as it did before. It just chuffs out smoke. It smells like unburned fuel.
A neighbor came out, and suggested, that instead of setting the motor at TDC, maybe it should be 8 degrees, or whatever it should be for the motor.
I don't know what the timing should be, but could this be the problem, or is there a problem with the injector pump? Is there a way to tell if the injector pump is working?
I hope someone can get me on the right track to get this thing running.
It's a great tractor, but for now till it runs, it's a space taker upper.

To me it sounds like you have the engine timing off 180 degrees. If there is fuel getting to the injectors then the pump is probably working. I would pull number 1 injector out and see if the piston is at or near TDC not that you have number 6 at TDC.

to add to what cowman said checing for tdc both 1 & 6 piston are up at the same time one on compression and and the other on exhaust stroke so the best way to tell which is on the compression stroke it to remove the valve cover and see which cylinder has the exhaust valve open

Time it at 18 and it'll pop right off.

If you are sure it is on correct stroke is it
spinning over good. try a light mist of starting
fluid. you could plug in block heater. some times
the first start is a little rough.

So what your saying, is to turn engine to 18 degrees BTDC. then time injector by lining up the mark on the injector gear, to the pointer.
By the way, I did have the valve cover off, and after watching the first valve, which is the intake valve, open and then close, then I spun it up to 0 degrees on the flywheel.
I will try that and see what happens.

rejohn sounds like 180 degrees off timing this is always the case with that engine, if it will not start try 180 degrees.

Actually if it is timed to #6 rather than #1 it is 360 off, not 180. Those engine will usually run even if they are timed to the wrong cylinder. Not very well and lots of smoke, but they will run. BTDT.

OK heres what I've done. Yesterday, after reading the helpful hints I was given here, I turned the engine to 18 degrees btdc. I pulled the injector out, turned it to time up with the pointer, and re installed. Fuel was up to the injectors, so I tightened up the lines, and tried starting. It cranked, but just a little smoke came out of the pipe. Frustrated, I left, but came back this afternoon, and instead of pulling the injector, I removed the 3 bolts on the injector drive gear, and turned it 1 turn, re aligned the mark and tightened the 3 bolts back down. I did this, after making sure it was again on 18 degrees btdc.
I tried it again, and this time, I have alot of grey smoke coming out of the pipe. Enough to fill the shop with smoke in a very short time.
But it didn't start.
I even plugged in the block heater, to warm the engine, to see if that would help. It didn't.
There are 2 new batteries in it, and new battery wires. I'm not sure how fast it should turn over, but it seems like it may not be spinning as fast as it should. Would this be a problem, if it's not cranking over fast enough?
I think I'm very close, but not quite. This is my first diesel overhaul, and even though I know alot about engines, diesels are a little different than what I'm used to.
