I ran out of memory so the video cut short. Here are the valve clearances on an isx 400-500.
Intake .014/ lock nut 33ft lbs
Exhaust .027/lock nut 33ft lbs
Injector 71 ft lbs/lock nut 55ft lbs/ loosen 3 times after marking and check the marks didn't move.
Jake brake .276 yes .276 not .0276. Lock nut 15ft lbs. Push the rocker back so it rests against the cam. Then check the clearance. Double check with 1-800-cummins technical support.
Then order is
A 6
B 2
C 4
A 1
B 5
C 3
The rockers(intake, exhaust) that are loose and not being pushed are the ones that's ready for adjustment.
