I was wondering if anyone has found a compression tester or adaptor that works on the Doosan D34 bobcat engine injector ports? It has no glow plugs to do a compression test on so i am looking for a way to do it through the injector ports. Has anyone found a solution? Ideas?

Thanks for any help you can offer.

We had a special tool in the shop for that, it is shaped like a injector and that is how we compression test all D Engines (D18, D24 and D34)
I can see if I find the number, you should be able to order it.

I still have not been able to find it. It was encouraging to hear that they make one.
