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 mus t not be worn or damaged. Components must be free from rust or other corrosion. Clean with

a non-corrosive cleaner if neces sary. 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.

Torque figures for flared and ‘O’ ring fittings

The torque figures  given in the table below and the table given on page 7 should be applied to the nut of the

fittings whic h follow: 7 degree flared fittings (C), 45 degree flared fittings (C), inverted flared fittings  (C2),

‘O’ ring fittings for a recessed drive, ‘O’ ring fittings for air conditioning and swivel nuts (C2). The figures should

be used for applications which allow these working pressures: 7750 to 4450 kPa (25 to 5000 lb/in2). The

torque figure depends on the size and type of fitting.

Torque figures for const ant torque hose clamps

Use a torque wrenc h for the correct installation of a constant torque hose clamp. For a constant torque hose

clamp to be installed correctly, these conditions must exist:

The screw tip (D) must extend by 6,5 mm (0.250 in) beyond the housing (D2).

The belleville washers must be collapsed almost flat after the screw (D) has been tightened to a torque of

 +/-  Nm (98 +/- 9 lb in).
