Recommended torque figures
Exceptions to these torque figures are given in the Workshop Manual where necessary.
Before any components are fitted to the engine, ensure that they are in a new or close to new condition. Bolts
or threads must not be worn or damaged. Components must be free from rust or other corrosion. Clean with
a non-corrosive cleaner if necessary. Do not lubricate the threads of fasteners. Rust preventative which has
been applied by the component supplier for shipping and storage is acceptable. Certain components may
require an application of a particular lubricant, details are given in the Workshop Manual where relevant.
