What should the torque be on a torque table?
Torque specifications are shown either as an exact figure, or a specific range. Follow any special instructions or multi-step directions carefully to assure correct final torque. There may be different specifications for different size bolts, bolts in different positions, tightening bolts in several stages, or a cold engine vs. a warm engine.
What are the torque settings for head bolts?
SOURCE: head bolts torque settings According to my haynes manual for G-S reg, 1989-1998 it goes as follows, Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head. Stage 2:-Tighten all bolts to 40Nm or 30lb ft. Stage 3:-Angle tighten all bolts a further 60 degrees. Stage 4:-Angle tighten all bolts again a further 60 degrees.
What does torque mean when tightening bolts?
When you tighten a bolt in a bolted joint, you use a twisting force, called torque. Torque is related to bolt tightness , but many additional factors – such as friction – combined into a single “nut factor” can have a significant impact on the relationship of torque to the tightness of the bolted joint.
