The torque specification for the injector bolts on a Caterpillar 3126B engine typically ranges from 18 to 22 ft-lbs (24 to 30 Nm). It's important to follow the manufacturer's guidelines and use a calibrated torque wrench for accurate results. Always ensure that the bolts are tightened in the correct sequence to prevent any damage to the injector or engine components. Additionally, consult the engine's service manual for specific torque values and procedures.

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.
The torque specs for a Cadillac depend on which engine it has. For most 425, 572, 368, and 500 engines, the torque for the head bolts is 115 ft. pounds. The torque for the cam bolts is 25 ft. pounds, and the torque for the valve covers is 10 ft. pounds.

The 3800 Pontiac engine had bolt torque specification is 160 pounds. The head bolts should be torqued in 40 pound intervals.
For the 1996 Chevy S-10 4.3 liter, the torque specs for the crankshaft damper bolts is 70 ft. lbs. For the cylinder head bolts, the torque is 65 ft. lbs, and for the engine mount-to-head bolts, the torque is 35 ft. lbs. For the engine mount-to-frame bolts, the torque is 52 ft. lbs.
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.
The torque specs for the bolts on the engine cylinder head can vary depending on the specific make and model of the vehicle. It is important to consult the manufacturer's specifications or a repair manual for the exact torque values.
