IH 674 - D239 Head Bolt Tightening Order

speedfreak · Apr 19, 2010

Hi Guys

Would be very greatful if anyone can supply information on the order to tighten the head bolts for a D239 engine.

I believe the torque setting should be done in 3 steps

1) 30 ft-lbs
2) 60 ft-lbs
3) 90 ft-lbs

If this is wrong any info would be much appreciated.

I don't know it that engine has a special way but most start in the center and in a circular motion keep working towards the ends.

30-60-90 is a good method

Some heads have more than one size bolt and the differentt sizes are tightened to different specs.
