element (32), then loosen the screw (33).
23 Loosen the three screws (34) fixing the support
(35) to the cylinder head, then remove the sup-
port (35) by unhooking the spring (36) from the
fin disc (37) and the tie rod (38).
24 When mounting, remember to tighten the
screws (34) to the specified levels and avoid a
drop in pressure with the risk of burning the
cylinder head gasket. We therefore recommend
checking the other five cylinder head screws
too.
25 Remount the conveyor [ 6.1.A] .
D) Replacing the fin disc on the pneumatic
device
31 Remove the conveyor with the tank [ 6.1.A] .
32 Unhook the spring (36).
34 Dismount the fin disc (37) which is fastened by
the screw pin (39) and disconnect the tie rod
(40).
35 When mounting,
– Make sure the washer (41) is correctly posi-
tioned underneath the fin disc (37) and
securely tighten the pin (39) in such a way
that the fin disc (37) moves freely;
– Check that the tie rod (40) has a centre dis-
tance between the ends that brings the fin
disc (37) to a distance of 13-15 mm from
external surface of the flywheel (42).
Otherwise tighten or loosen the central ring
on the tie rod until you achieve the right dis-
tance. This tie rod adjustment should be con-
sidered “preliminary” and can be altered dur-
ing maximum speed adjustment.
