sw corner ia. | I don't know what injectors your motor has but if it has top stops intakes should be 11 and exhaust should be 23. injectors are 6 inch pounds which is about a quarter of a turn( past zero lash).
standard injectors (earlier) are 14 intakes and 27 for exhausts, 72 inch pounds for injectors (some go 80 for injectors so yours may be different than this, get your cpl code and talk to cummins to be sure).
just did mine a couple months ago in my shop and the data plate on the left front on the accessory drive cover should tell you.
do you know how to sequence the valves by rotating the motor over while watching the pointer also on the left front? kind of a pain to jump down and rotate with a wrench but doable..
in case you don't it is:
Cummins N855
Timing Mark on A
When Valves on #5 are closed
Set Valves #5
Set Injector #3
Timing Mark on A
When Valves on #2 are closed
Set Valves #2
Set Injector #4
Cummins N855
Timing Mark on B
When Valves on #3 are closed
Set Valves #3
Set Injector #6
Timing Mark on B
When Valves on #4 are closed
Set Valves #4
Set Injector #1
Cummins N855
Timing Mark on C
When Valves on #6 are closed
Set Valves #6
Set Injector #2
Timing Mark on C
When Valves on #1 are closed
Set Valves #1
Set Injector #5
