seat exhaust side bolt then torque opposite side to 9 ft/lbs
In order to change the torque you will need to tighten the bolt on the exhaust side of the injector to fifty inch pounds. Tighten the drivers' side bolt to nine foot pounds.
I need a specific year... preferably with engine serial number... in order to answer this. Cat never seemed content with the 3126, and always had to change something on it.
The torque specifications for an injector, on a Caterpillar see nine diesel engine, is seven pounds. Over torque in the injector can ruin it.
To change an injector on a Mack 350 mechanical motor, first, ensure the engine is cool and disconnect the battery. Remove the injector lines and the hold-down bolts securing the injector. Carefully pull out the old injector, clean the seat, and then install the new injector with a new seal. Finally, reattach the hold-down bolts and injector lines, and reconnect the battery before starting the engine to check for leaks.
To adjust the injector on a Cummins NH 220 engine, start by ensuring the engine is at operating temperature and is turned off. Remove the injector lines and loosen the injector hold-down bolts. Carefully adjust the injector by turning the adjusting screw to the specified clearance, typically around 0.012 inches, and then retighten the hold-down bolts. After adjustments, reattach the injector lines and check for leaks before starting the engine.
headbolt torque is : 62 ft/lb cam hold down bolts is : 13 to 20 ft/lb
the longer (new bolts) are to torqued to 48lbs and the shorter ones are to be torqued to 45lbs then turn the bolts an additional 90 degrees the bolts need to be replaced with new one because they are streched when you torque them down
To change the number 5 injector on an N14 Cummins engine, first, ensure the engine is cool and disconnect the battery. Remove the valve cover to access the injectors, then carefully disconnect the injector wiring harness and fuel lines. Use a socket to remove the injector hold-down bolts, pull out the old injector, and replace it with a new one, ensuring proper alignment and torque specifications. Finally, reassemble the components in reverse order, reconnect the battery, and check for leaks before starting the engine.
if your cylinder head is made out of aluminum ,i would say to re-torque the head.the bolts holding the head down get lengthened by the head expanding faster than the bolts.
Install the new spark plug and torque it down to 15-21 ft-lb (180-252 in-lb). Install the coil pack and torque the bolts down to 64-95 in-lb (5.33-7.2 ft-lb). Install the new spark plug and torque it down to 15-21 ft-lb (180-252 in-lb). Install the coil pack and torque the bolts down to 64-95 in-lb (5.33-7.2 ft-lb).
Remove valve cover, 2 wires from injector, the fuel line coming from the fuel rail to injector, the lock nut on the head where you just removed the fuel line from, put a nut on injector tube and use a pry bar to pop out the tube, remove the rocker arms (do not mess with adjusting screws) only take out center bolts 10mm, remove 2 8mm hold down bolts on injector, put pry bar under injector hold down and pop intector out. Follow these instructions in order
20nm followed by 240 degrees personally i prefer 20nm then 2x 120 degrees to take the head bolts down nice and easy
