no, EGT would go down with less fuel. there is no such thing as a lean condition in a diesel, just low power from lack of fuel.

Thanks Chris, I am really getting senile??

orren, see post #103, it is now correct. Another way is that when you are positive you are at TDC of the compression stroke of #1 cyl and have the IP timing mark lined up, there should be a tooth lined up with the little cast pointer in the shutoff window. If this was a running engine, the next...

No that would not work at all, you would be out of time 180° at the HH. Now I am wondering if I remember how many teeth are on the HH, so 60° may be wrong. My brain is getting rusty, I'll look it up tomorrow to be sure.

You have to know the #1 cyl is on compression stroke, TDC. (both valves loose, #6 valves at overlap) Then line up the timing pointer on the IP (under the cover with 4 bolts). Now turn the engine backwards 20° exactly. (my bad earlier, it is 20°) That puts the plunger at the bottom of it's...

With #1 at TDC and the timing pointer on the IP lined up, turn the engine backwards exactly 20°. The HH should now come out, but do not apply force. edit: my bad it really is 20°!!

testing the HH is very easy, remove the two keepers so you can pull the plunger out. hold the plunger in your fist for 5 to 10 seconds. if it will go back in it is bad. yes it fits that closely. also if the surface of the plunger has elongated swirl marks that indicates excessive wear, it should...

my money is on the HH plunger sticking. this would account for almost 100% of your problems. the fuel system is so simple that many people over think it. if you have fuel pressure in the final filter relative to the rpm and it still stalls, it has to be the HH. also remember a worn HH will not...

if you have good fuel pressure at the final filter that is all ok. you can flush the HH plunger by removing the center plug, turning engine so plunger is at lowest point, remove fuel supply line to HH, set throttle to max, and use clean air and fuel to push fuel and air down the plunger. this...

running out of fuel is EXTREMLY hard on the HH and can take one from working ok to dead in just a few seconds. at 2000 rpm the plunger is stroking 6000 times a minute and no fuel = no lube.
