The 12-valve 5.9L 6BT Cummins came out of the box with 230hp, 440 lb-ft of torque and a P7100 inline injection pump. While it began life as an agricultural engine, its popularity picked up immensely once it was put into Ram trucks starting in 1989.

What are the torque specs for a 5.9 Cummins?

Cylinder Head Torque Settings

For the Cummins 5.9-liter engines made between 1983 and 1989, the bolts in the cylinder head must be tightened to 89 foot-pounds plus an extra 1/4 turn. For engines made between 1998 and 2003, the figure is 77 foot-pounds plus the extra 1/4 turn.

What torque settings should head bolts be tightening to?

What Is The Torque For Head Bolts? Locking the head bolt at the third stage of an increase sequence (1-2-3) makes sense. Torque can come from each bolt between 7-9 feet. Two, tighten each bolt at 14-16 feet of torque each time.

How much HP does a 5.9 Cummins have?

The last generation 5.9l Cummins engines from 2003 to 2007 used HPCR pump and 24 valves. They have 305-325 HP and 600-650 lb-ft of torque. Cummins made a displacement change in 2007.5 to the 6.7l Cummins diesel.

How much horsepower does a 2006 5.9 Cummins have?

Engine: 5.9-liter Cummins turbodiesel in-line 6 with 325 horsepower at 2,900 revolutions per minute and 610 foot-pounds of torque at 1,600 rpm.

Do head bolts have to be torqued?

In most cases you don’t need to retorque head bolts or studs. If the bolts or studs aren’t tight you will lose compression or get coolant in your cylinders. You can use bolts or studs based on application, but studs tend to give more consistent torque values. Never reuse Torque-To-Yield (TTY) bolts.

What are the torque specs for head gasket?

Many cylinder heads require multiple torque sequences to achieve proper tension. For example, a 10-bolt cylinder head may require you to tighten them all first to 42 foot-pounds in a specified order, then to 75 foot-pounds in the same order. Improper sequencing or torquing of the bolts may result in damage.

What order should you tighten cylinder head bolts in?

Normally you would tighten conventional head bolts in a crisscross pattern in three steps, to one-third, two-thirds, and then to the final torque. Stretch bolts are tightened in a torque-plus-angle sequence. Various engines use similar but different sequences and specification.

How fast is a stock 12 valve Cummins?

How much boost can a 12-valve Cummins hold?

Yes, the rule of thumb is 40-50 psi of boost, but that’s more because of the increased drive pressures associated with more boost.
