Truck Repair: cummins ism, screw out, jam nut

Question
i was wandering if you could tell me the procedures for adjusting the valves on a ism engine cpl # 260700 & for a n14 not electronic. any information would be appreciated
thank you.

Answer
On the electronic engines,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 rivet 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.
  On the STC,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 torque to specs to bottom injector plunger.Then tighten the jam nut down.Adjust the Injector first,then the valves.
On STC it would be greatly advised to run injector flush through the fuel system for an hour to clean carbon off injector tips to prevent plugging spray holes causing a missfire.Cummins sells it in a metal can & you sill need a return & suction line to hook up to engine(one at fuel inlet & one on fuel return) and run it out of the can.
You adjust the overhead the same way as the electronic engines except you torque the injector down to 125 INLBS & lock the jamnut.
