Ford 4600 timing

Hi
i just replaced the fuel pump, the old one was leaking, it was running before, but now it will not crank (i did make sure that the fule pump is set to the same holes, and it is at the o degree mark). I am thinking that i did not get the correct timing mark. Actually really cannot find one, on the crankshaft gear. so which piston is # one? from the front of the engine/tractor? thinking if i know this i can look at the valves at the top to know when/where it is, and should be able to get timing of the fuel pump set that way.
 
You need to give us a little more info.
Usually you do not need to remove the whole timing cover to replace the pump, just the little cover in front of the gear. The pump drive gear is held captive and can not skip out of time.
Did you remove the whole timing cover?
If you messed with the gears it is very important that you get it timed right as the valves/pistons are interference meaning you can hammer your valves if the cam is not timed right.
See the photo below for the correct timing on that engine.
Also you state that now the engine will not crank.
I assume the starter is working correctly and the engine cranks but will not start?
Answer those questions and someone here can help you better.

I am going to ask for clarification of "will not crank". If you are saying it does not even turn over/spin (which is how I would interpret "will not crank") I would be looking at starter/battery cables/switch/generally following voltage around to see where the circuit might be broken. If it is spinning, but not fireing, might want to make sure you have the system bled since you removed the pump. Unless you rolled the engine while the pump was off it should not have gotten out of time enough to not be able to start. If you did spin the engine then you need to ask UD to scan the pages from his manual and forward them to you. I have them as well.

Good Luck,

yes the starter does trun over the engine, my bust, and it seems to fire, it does white puffs of smoke, but there is a slight knock. yes i did take the whole timing cover off, following the shop manual that said too, i reckon that is where i made the mistake. Also, the picture you show, that is much more detailed than what is in the shop manual i have. i believe that i see where i might have went wrong. But that is also why i was thinking i could use the actual placement of the #1 piston, with your picture that should all line up correct?
 
Micky,
#1 piston is the one closest to the radiator.
But the truth is I don't know where #1 is in relation to the photo I posted.
I think at this point I would recheck the front gears to match the photo. The pump gear is indexed to the shaft so it can't get out of time there.
BTW, most of these tractors I have seen the pump was not set to the zero line but 1 to 1 1/2 lines below zero.
 
thanks on that, is it possible (i got it as a used tractor), that someone has done some engine work, and did not put the camshaft drive gear back in the correct oreintation? The reason why i ask, i can not get any of the three timing dots on the camshaft drive gear to line up with the either the Camshaft gear's one dot, or the crankshaft gears one dot. But there is a tool mark, like a punch was used, on the camshaft drive gear, and if i use that to align to the crankshaft, i also get the camshaft gear's dot at the 9'oclock posistion as shown in your picture.

Right now i think i will pull the valve cover off the top and see if i can make that #1 is at top.
