I'm currently overhauling a 986 that had a cracked sleeve. While the head is at the machine shop, I pop tested the injectors. They all popped off around 2500 psi. The atomization seemed to be less than ideal.
I have a manual for the 400 series block and it says 3600 to 3750 for new and 2900 used for the 66 series. It doesn't mention the 86 series. I'm assuming the pressure is the same but I'm not positive.
I know my injector tester is good because at the same time I tested some injectors off a JD 4250. They popped off within spec and had a great pattern.
Can anyone confirm my manual is correct? Thanks for any help.
