Beta 1461/C15 Mode D'emploi page 13

Repeat the procedure to remove each torsion spring
in turn.
Once all the torsion springs have been removed,
Securing Tools D816 and D817 can be removed from
the ends of the inlet camshaft and the inlet camshaft
itself can be removed.
For further dismantling, lift the carrier bracket off the
D819 Mounting Fixture, turn the carrier bracket over
and locate it back onto the pillars of the Fixture to give
access to the eccentric shaft.
Re-assembly Notes: -
Use D819 Mounting Fixture on the workshop bench.
NOTE: For Installing the Inlet camshaft, levers, torsion
springs etc., the carrier bracket must be located on to
the D819 Fixture the same way up as when the
torsion springs/inlet camshaft etc were being dis-
assembled.
NOTE: Ends of Compression rings face upwards.
Inlet camshaft - Always
check condition of the
Plain Compression rings,
they can break easily. To
install - carefully pull
apart and fit from the
front. Press ring from
one side to engage the
catch on the other side.
IMPORTANT: When
installing the inlet
camshaft, the curved
edge of the rectangular
section at the rear of
the camshaft MUST BE
pointing downwards in
order that the camshaft
is in the correct
position when the
carrier bracket is
installed in the cylinder
head.
Fit Securing Tools D816
and D817 to fix each end
of the inlet camshaft to
the carrier bracket.
Lubricate Intermediate
Levers with engine oil
and install
IMPORTANT Used
Levers MUST BE
reused in the same
position from which
they were removed. Fit
each Intermediate
Lever in turn, securing
all of them in place
with D818 Clamps.
Installation of torsion springs
Re-fit each Torsion Spring in turn.
Place the torsion spring in position with no tension
applied.
Fit D814 Tool to the carrier bracket and secure in
place by inserting its bolt, from the top, through the
Tool and through the Carrier Bracket. Fix with its nut
from underneath - tighten nut.
Using a suitable pair of adjustable pliers fit the jaws to
span across from the back of tool to the front of the
torsion spring plate.
Maintain the spring in this position with the Pliers and
Slide the Safety Pin in place - fully through both sides
of the Tool, The Safety Pin will restrict the torsion
spring's movement, backwards.
Remove Pliers and screw in the spring retaining screw
(Tx30) to secure the torsion spring in place.
Remove Tool D814 and fit to next cylinder/spring
position, repeating the procedure on each torsion
spring, in turn.
Install spark plug tubes and ensure rocker arms are
secured on hydraulic lifters.
Install the camshaft/carrier bracket assembly back
onto the cylinder head.
Insert the 8 x nuts along the inlet camshaft line, the 4
x nuts on the front bearing section and the nut on the
bracket (exhaust side) ALL FINGER-TIGHT only.
Tighten these nuts, from inside outwards to an initial
torque of 5Nm and then tighten down to 10Nm.
Remove the D818 Clamps and remove Securing Tools
D816 and D817 from the ends of the inlet camshaft.
Rotate the eccentric shaft fully clockwise and fit the
torsion spring back on to roller.
Refit oil line, chain guide etc., to continue re-assembly
of cylinder head, VANOS units etc.
Carefully and slowly, in a
controlled manner, close
the Plier jaws to compress
the spring to a position
where the spring plate
goes beyond the holes in
the Tool which accept the
Safety Pin.
