Default Old CAV Injector Tester

Just wondered if anyone has or knows where I could get info or a schematic on an old CAV Injector tester. Don't find much info anywhere on the web on them.

Here is a picture of my nozzle tester. You could build one out of a hydraulic jack. I think mine has a 3000 lb gauge on it.

I have two of the old-style testers, what information do you need?

Hi Peter, well on the tester, up near the guage there is a horizontal valve that shuts off fuel flow to the injector line it looks like. On mine if I open that valve it leaks around the copper gasket on the nut that holds that valve in the housing.....I machined a new shaft for the valve and knob as the old one was broken off......but something seems to be missing to seal that shaft off when pressure is sent to the injector.

Would you have a manual or parts book by chance.?

I'll have a look in my CAV manuals, might be something there.

There are two types:

7044-122 The 'old' type with an injection pump as part of the rig.

7144-664 The 'new' type, all enclosed.

I have instruction books for both.

OK, I'll have a look at my two and see what gives.

I'll also scan the instruction books and put them in the CAV Diesel section on the websites, won't be for a few days though.

I'm waiting for some parts lists that show a breakdown of the unit.
