Truck Repair: n14 valve adjts., screw out, celect


Question
can you please send me a copy of valve adjts., injectors adjts. and sequence for n14 motor.

Answer
For ELECTRONIC engines
On the Celect,you adjust valves & inj on same cyl.The mark A is now 1-6,B is 2-5, & C is 3-4.Valves are Int 0.014 & Exhaust is 0.027.The injector you hand tighten screw until injector plunger bottoms out.Back screw out 2 flats,ie turn corner of lock nut to align with the riviot in the rocker lever(pushtube side),then back out screw two "corners" then tighten the jam nut down.Adjust the Injector first,then the valves.
STC engines are the same except for injectors torque to 125 in lbs & lock the jamnut down.
