Hey all,

I bought a timing guage indicator so I could try the "book" method of timing.

I am not sure I followed the procedure correctly, so here is what I did:

1. Set engine to TDC. With injectors removed, insert rod into #1 and turn engine until rod it as its highest. Sanity check - verify timing pin inserts. Mark crank.

2. Rotate engine back until dial indicator hits a flat spot.

3. Preload guage 1 mm.

4. Turn to TDC.

5. Take reading - 2 mm !!

I take it my timing was VERY ADVANCED!!!!!!

If I set the pump (not original to the truck) so the marks line up - 1.25 mm !!

It doesn't take much movement to get the pump to the 1.4 or 1.7 range... by the recommended 1/8" bump I'm already at 2 mm. Do I have some kind of hot rod pump or maybe I'm doing something wrong???

What should I try to set the timing too???

I have not experimented with the timing on this pump very much since the diesel shop turned up the fuel screw and adjusted the RPM and idle screws...they pop tested the injectors around 3350 and said they sprayed fine, no injector problems.

Thanks for your comments!

 

By the way, the reason I am checking the pump timing is that I was having BLUE SMOKE on startup that is VERY potent (burns eyes) and also as engine cools down at idle... and my fuel economy is only around 16.5 empty.

 

I'd set it to 1.7mm= 17*. Nothing special or wrong, you were just advanced.
