TIGHTENING TORQUES:
The tightening torques are expressed in metre Decanewton (mdaN), the official torque measuring unit:
0.981 mdaN = 1 mkg (former measuring unit).
In practice, 1 mdaN = 1 mkg.
UPDATING THE MANUAL WITH ADDITIVES:
Additives should be ordered immediately on receipt of the DOCUMENTATION BULLETIN announcing that
they are issued.
The updated sheets must be added to the existing pages in the manual or replace the corresponding ones. They
are identified by spots located to the left of the shortened volume number placed at the bottom right hand side
of the recta page:
Example : 1 spot
l 8531 additive no. 1 ; 2 spots l * 8531 additive no. 2, etc.

Rotate the cl-ankshaft through a complete turn In the
normal direction of engine rotation.
Record the clearance of cylirlder No. 1 inlet valve:
the figure should be comprised between :
0.05 and 0.25 mm eck and adlust ihe valve locker clearances.
Inlet = 0.15 mm
Exhaust = 0.20 mm
Refit:

REPAIR OF THE HYDRAULIC SYSTEM
FITTING PRECAUTIONS
c) Fitting..
Only use joints of a quality compatible with LHM mineral fluid.
To connect a union, proceed as follows: Fig. Ill
0 Position sleeve-seal u a )) lightly coated with LHM fluid ; this sleeve must not reach the extremity of pipe c(b)).
l Centre the pipe in the housing by lining it up with the axis of the hole, avoiding all stress. (Ensure that the
end c l Start screwing in the union-nut by hand, slacken the unit fixings, if necessary, to make this operation easier.
l Tighten nut moderately: excessive force could cause a leak because of the deformation of the pipe.
Tightening torques:
3.5 mm dia. pipe
0.8 to 0.9 m.daN
4.5 dia. pipe
6.0 mm dia. pipe 0.9 to 1.1 m.daN
The design of the various seals ensures that their sealing action increases with fluid pressure. In the case of a
leak, check the tightening torque of the union-nut. If the leak does not stop, replace the sleeve-seal.
To connect a rubber tube, a rubber ring of suitable diameter has to be positioned between the tube and the hose clip.
9. CHECKS ON COMPLETITION OF WORK.
On completion of work on hydraulic units or the system itself, check the following:
a) The union for leaks.
b) The clearance between the pipes: pipes must not touch one another or any component, nor may any other
unit., whether fixed or movable, exert any stress on them.
