In this video you will learn how to check and adjust the injection timing on a 1994-1998 cummins diesel
PUMP NUT TORQUE 155FTLBS
STEP 1 remove injection lines
STEP 2 remove delivery valve holder and valve for cylinder 1
STEP 3 install dial indicator as far as it will go
Step 4 remove the oil filler neck
STEP 5 turn the engine CRANKSHAFT COUNTER CLOCKWISE until the dial indicator stops dropping
STEP 6 remove the pump nut DONOT DROP WASHER INTO THE TIMING CASE
STEP 7 install the gear removal tool and take the gear off the injection pump shaft
STEP 8 put nut back on shaft and tighten gear until it will just turn the pump over THIS WILL PREVENT THE TIMING FROM JUMPING IN THE NEXT STEPS
STEP 9 find the lift you want in the plunger for the amount of timing you want
STEP 10 rotate the CRANKSHAFT CLOCKWISE until the dial indicator reads the amount of lift you want
STEP 11 remove the pump nut gear again
STEP 12 turn the CRANKSHAFT COUNTER CLOCKWISE 1/4 TURN
STEP 13 remove the timing plug from the back of the timing cover
STEP 14 put the plug back in without the oring on it to make it slide better. Rotate the CRANKSHAFT SLOWLY CLOCKWISE while pressing the timing plug into the hole against the cam gear, you will feel a pop as the pin slides into the hole in the cam gear
STEP 15 clean the pump shaft very well with brake clean and compressed air then tighten the nut just till it will bite the shaft and spin the pump
STEP 16 remove the timing plug and rotate the CRANKSHAFT COUNTER CLOCKWISE until the needle stops moving
STEP 17 put the plug back in the timing cover and rotate the CRANKSHAFT CLOCKWISE while putting pressure on the plug again, watch the dial indicator until the pin pops into the timing hole in the cam gear, if the needle is where you want it then back out the plug and put the oring back on. then install it back into the housing but leave it out far enough that it doesn't rub on the cam.
STEP 18 torque the injection pump nut to 155ftlb and re assemble the engine
