Didn't like the glycerin filled "precision" gauge as it was hard to get an exact pop pressure (because of the fluid dampening), so I added a 4-1/2" dry gauge to the mix, works great with both gauges on as I can test and verify on the same unit.



OK, so it's pretty boring for most people, just thought I'd show pics of our new toy for those who like tools.

Did you buy that or did you build that? What did it cost you?

I doubt I could afford anything like that anytime soon, but something like that could come in really handy...

Do you have the ability to adapt to different injector thread sizes?

Tom,

Great job! Is the pump itself a standard item and how expensive is it?

Have a great day,

Nice! One question: what do you use to let the pressure down when you're finished with an injector?

Good show. I have been lusting after one of those for a long time. Not boring at all

Bought the tester without the gauge, traded some parts and $150 for it, then had to find a gauge.

Have a few different adapters, but with a lathe and some bar stock, I can make about any adapter I need. It came with an adapter for a cummins, so I made the adapter for the Bosch injectors out of bar stock (look closely in the pic).

Std item if you want to import from India. Not many here in the this country as far as for sale since they last forever and not much demand.

They generally sell for around $350-600 depending on what you can find, calling around to injector shops might yield a broken one for cheap that you can fix up (like I did.)

Larry: see above for costs and std item info.

Stevo: You just D/C the injector to let the pressure off. High pressure, but very low volume, so about two drops lets the pressure down from 2kpsi to zero.

Check out a new website, it's a new business I'm going to try, have to find something to do in the winter and it seems to be something we could all use:

Nice tester!

I built a crude version (works well, though ) from a two ton bottle jack, 3/4" NPT tap, plumbing fittings,metric/NPT fittings, PVC reservoir, 3000psi gauge(glycerin), old IP injector line and a touch of JB Weld. Mazola oil as my test liquid (my wife appreciates the garage not smelling too garagey).

Clever idea on the non-dampened additional gauge.

Where did you find a source of assorted shims? (BoschUSA was of no help when I talked to them).

So how much would it cost me if i just wanted mine pop tested and made to open within 2 bar of each other?
Thanks
David

Check out my new site, I'll have to come up with a price just to do yours, give me a few days:

Oh, one thing, not having new injector nozzles might not make a difference in how it runs, or it still might??? Maybe we'll just have to experiment?

jbaj007,

Would like to see some pictures of your bottle jack style injector tester.

Mercedes Man,
Digital image capability is down for a while (new hardware and OS being "configured"), but I sent you an email.

Hay...Good show, both you guys

"Where did you find a source of assorted shims? (BoschUSA was of no help when I talked to them). "

These are the shims to correct the pop off pressurs. yes? I wondered how I would change anything, if need be, when I borrewed a pop tester last year. It seems having some assorted shims would be a "must".

"Lifes too short to drive a boring car"

Here's a link to a injector tester for $149. http://www.hardydiesel.com/acc/allacc.htm

When I first heard about this unit on the mbz.org listserv, it was on sale for $99. Can't vouch for the quality or accuracy though. Without access to the shims, I think these things would only be good for basic diagnostic work. They'd also be helpful with diagnosing the spray pattern and pop pressure on CIS injectors for gasser rigs too.
