I have been under it and I have a mark on the front cover but nothing on the inj.pump so I dont know what my inj pump is running at. I need to turn it up but I'd like to know the percent ? Just turn it an 1/8 inch but i have no idea if it has been done because of the fact no mark on inj. pump. ANY INFO WOULD HELP, THINS YOU.

 

In all honesty this might not be the best method to go about it but.... if i didnt have a tool to read lift i would probably do it this way.

First thing id do is mark where your pump is now incase you mess up and need to put it back to stock... dont skip that step.

Id push the the pump as close to the head as you can by hand and tighten it down by one nut... On my truck that was a tiny bit more than 1/4" advanced... Then i would mark the pump and timing case in the same spot. Then back the pump off 1/8" from that spot. On my truck that would be a 1/8" timing bump. (quarter inch minus eighth inch equals eighth inch)

if it doesnt seem to run right after that you can always move it back to where it is now but it should be fine.

 

Don't just shove it to the head till it stops, that can give you way to much timing. Just because yours was 1/4" his could be 1/2"...

They only TRUE way to know would be to buy the timing tool and check were you are at. Aside from that, if you do no towing I would feel safe marking the pump and moving it 1/8", if you plan to tow at all though I would get the tool and check were you are at now so you don't melt something...

Also a good rule of thumb is if it starts rattling like a old 6.5 Chevy diesel you've gone to far. If you start hearing timing knock you need to back it off. Again only use this method if you are not going to tow at all.

 

I agree but without the tool i couldnt think of another way to go about it. If these trucks has any consistency to their build then youd think it would get him within a row of buttholes.

 

Almost all factory installed pumps come with a timing mark, I've never seen one witout but I'm sure there are some floating around. Alot of replacement pumps don't, so who know where the tech set the timing at and weather or not someone else has bumped it already.

If you don't have the tool the move it a little at a time (less then 1/8") and listen for excessive rattle is about the only way to go. And when doing that I would not dare tow a trailer.

 

Thanks, Where can I buy the timing tool? I will buy it because I now love first gens.

 

What tool are you talking about? Icould not find anything on-line FOR THE BOSCH V.E. PUMP. found several for the P. PUMP but nothing for the V.E.. I NEED TIMMING.
