Bosh timing adapter

[Mel Fuelling]

R. E. ,

Advancing the injection pump timing does not change the amount

of spill port lift(fuel volume), it starts the pump stroke sooner and has delivered more of that stroke at the point where we are measuring it(TDC). So, advancing pump timing should not affect

the service life of the VE pump. If we advance the pump to a more efficient point, and don't go too far, we will have more

cylinder pressure, more smoke at torque peak, etc. and more

stress on the 5. 9. But being that we are not increasing fueling,

but changing the point that it occurs, we probably are not measurably affecting service life of the 5. 9 if the best correlation to service life is the total amount of fuel consumed.



Case 500D,

The VE spill port plug is 8mmx? as NOMOFO stated earlier. As R. E. said, try it and see if it measures or if it fits.



Scot, Tim1, & Mark93;

Your questions about converting to metric are logical and it can

be done, but it triples your chances of making a mistake that is

easily avoidable.

Hi Mel, Got the DI, but haven't had time to use it yet. I'll keep you posted. Thanks bud. Tim

Just received my Sir Tool adapter. Slightly bent extension. I think I can straighten it? Collet does not get as tight as I would like but I'll be delicate.

Mel and Case: my reference to 8mm was about the adapter's collet not the spill port plug. Looking at the adapter I would guess the spill port is 6mm. Since I'm going to change injectors I think I'm going to find TDC by fabricating/using an adapter that has a rod down the injector hole. Now I'll need to get a magnetic base for the dial indicator for this step. Does anyone remember the thread where somebody made one of these adapters with an old injector?

TIA

Great posting!



When I read through all of the numbers & options I become confused and don't know if I "see' the answer.



Could someone summarize this posting in a clean, easy to read, list of parts req'd and where to order from.



Sorry! I feeling a little "THICK" today...

Hey Keeno,simply put adapter to go into the back of pump number va6015(28. 50delivered) Dial indicator to fit the adapter Mitutoyo PN mti2046F locate at tool store (60. 00) There seems to be concern about TDC, so I will build a tool to go in the injector hole to measure piston travel, will keep you posted! Tim (I've not got this done yet)

Keeno, the adapter is available at www.sirtools.com I missed that in my post, dam% it. Tim

Hey Tim1!



Thanks for the summary & info! I have always wanted to pump timing set for the Cummins but found then to be incredibly spendy.



This is just the ticket!
