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).
