| I did get the engine timed and inj pump put on and running. I did take frt inj.out and used a remote starte switch and bumped the switch untill I felt air comeing from that cyl and then I went to turn engine by hand to timeing degree specs,installed pump,it is running. Thanks to all for your great help. This was not as difficult as I thought that it may have been.

| The only way is trial and error, without watching the valves. Line up the timeing marks and try it, 50/50 chance on the first try, I"m not sure about the odds afterwards but still 50?50 I think. Good luck.

| Pull valve cover.
Right down first three numbers of firing order then dire toy under these right the other three numbers. This gives the opposite pistons.
Look to see what number is dire toy under the number one piston. Now turn engine over until the valve rockers on the number one opposite cyl. Are both at the top and they move up and down when you roll engine back and forth. Stop at the top when both rockers are not moving this is top dead center for number one.
if you need more info give me a call when you ready to do this.

| Okay you have a 6 cylinder. Pull the valve cover off and watch the rocker arms on cylinder #6. When they go into overlap #1 piston will be up on compression stroke, providing this is an inline 6 cylinder. Pulling the oil pan off will only tell you if the piston is up or down but not on compression stroke so you'd end up pulling the valve cover off anyway. 10 out of 10 times we have to do what we don't want to do.

| Can't you just pull the injector and put your thumb over the hole, like a gas engine? If it blows air around your thumb, it's on the compression stroke.
The fuel system is full of air now you can't hurt anything.

| If it has glow plugs pull #1 out and turn the engine over. This way you don't have to open up the fuel system and introduce air into it and have to bleed later on. That or check the front crank pulley or flywheel for markings. Are you trying to time the injection pump to the engine?

| Well, are there any timing marks, that would get
you close, though maybe 180 degrees off. Then,
could you pull an injector, and tell if it was
coming up on the compression stroke. Unless it"s
a Detroit Diesel, where every up stroke is a compression stroke!

| Inj. pump was taken off and engine was turned over after that[not by me] so I am trying to time the pump to the engine. Thanks
