WARNING: When valves are re
placed, it is essen-
tial to refit
(new) valves with the same part num-
ber
(1) as the previous ones, in order to prevent
an
y damage to the valve and seat.

The same part number can cover several mar-
kin
gs, and in this case the valves are fully inter-
chan
geable.
Sim
ply check that the new valves with a different
markin
g do indeed correspond to the same part
number.

Compress the valve springs (e.g. with
FACOM tool
U43L).
Remove the collets, the upper cups, the springs,
the valves, the valve seals using the pliers
Mot.
1335 and the lower cups. The wearing of gloves is recommended during
this operation.
Do not allow any product to drip on to paintwork.
We would like to stress that the utmost care
should be taken in carr
ying out this operation to
prevent foreign bodies from penetrating the
pipes feeding oil under pressure to the camshafts
(pipes located both in the cylinder block and in
the c
ylinder head) and in the oil return pipe.
Failure to follow this instruction would in fact ris
k
blocking the nozzles of the valve rockers and qui-
ckly causing damage to the rocker cams and fin-
gers. Cleanin

It is very important not to scratch the sealing
faces of aluminium parts.
Use the product Decapjoint to dissolve any part of
the seal which remains.
Apply the product to the part to be cleaned; wai
t
about ten minutes, then remove it by means of a
wooden spatula.
