Many service and maintenance jobs require that screw joints are reinstalled at a specific point in the operation. To ensure that this does not cause problems the following method should be used:

• Clean the joint surfaces. First mechanically and then with a solvent to remove grease and oil.
• Use new bolts and nuts in torque tightened joints where required.

• For screws that are only torqued tightened with thread locking liquid.

  When reinstalling use a few drops of locking fluid.

  NOTE: Always replace self-locking nuts with new ones.

• Always replace screws, or nuts and bolts, for torque and protractor tightened joints with new ones.
• The values below are accurate to within ±5%.
