3J D2 Injectors

Hi All
New to the forum from australia and just wondering if anyone can give me some tips on my D2 injectors they are leaking before they reach there cranking (breaking) pressure. I have cleaned them and reset them but still no good. I have had them to a local diesel service who said they couldnt help never seen that style before. I can't get a break down of the injector only a number for the complete injector which is discontinued. Has anyone got a part number or know where i maybe able to get a new nozzel assembly, injectors or parts.
Dan

Hope this helps!

It has a couple of scanned pages attached to it.

Here are the part numbers but good luck on finding them......may be limited to used or find and old time fuel injection shop.

I have all the tools and test equipment to work over those nozzles. Write to me for a quote; [email protected] Bill Walter Chapter One K.C. Mo.
