Some moderator or admin might want to make this a sticky?

So here's a write-up on how to set timing:

#1 - Turn over the motor with a crank bar with the timing hole on the pump open until you see the timing marker (using a mirror and a good light), when it shows up insert the timing lock pin.

#2 - Loosen the nut on the pump, it would be a good idea to have someone hold the crankshaft still so that you won't break the lock pin, then give it a bump with a hammer on each side until the gear pops off the axle.

If you already have your TDC in order, you will not have to do step #3..

#3 - Pull out your #1 injector and stick a long screwdriver in there so that you can see it move up and down, mark on your crankshaft pulley (i used the crankshaft sensor to mark by) when the screwdriver starts to move down, both when you turn it clockwise and counterclockwise, on my engine the TDC duration measured 38,5mm this is equvaliant to 19.25° variant in time, so you have to mark the center of this zone on your pulley... that is 19,25mm (on my engine, again this may differ on yours) from each mark you've already put there...

#4 - Now you have TDC... and with your lock pin in place on your pump you will have 13,5° timing (given that it has not been tampered with @ some diesel shop already)... you can now advance or retard timing by turning your motor counter-clockwise (to advance) or clockwise (to retard) by 2mm (giving that your crankshaft pulley is 740mm round like mine) for each 1° you want to adjust..

#5 - After you decide and turn your motor over to your preferred setting (16.5 is optimal with a stock motor, stock HG and stock bolts) you tighten up the gear again on your pump, and put everything back in place. Crank up your truck and enjoy your increased power output...

This way is both easy and not as time consuming as using a clock and needle...

I might add pictures, but i think i have explained it very well in words...

 

plese advise, where is the timing hole on the pump????????

 

it's on the drivers side on the pump, looks like a 15/16" nut

 

How dangerous is this? mm seem like a very small amount you go one cm and your screwed what was the best way you measured that?

 

Super dumb question. If I am standing in front of the engine, and I have the nut loose on the injection pump, which direction would I turn the crank pulley to advance 1 tooth (5 degrees)? Would I turn the crank pulley counter-clockwise? Essentially retarding the engine/advancing the injection pump?

 

i did some checking and there is another write up in the 12valve section on how to do the timing adjustment.
