New 1000 Series
To fit
1 If the damper is fitted to the rear face of the pulley,
fit the damper to the pulley with its inner flange
against the rear face of the pulley. If a viscous damper
is fitted, put the damper in position on the face of the
pulley (A1). Fit the clamp ring (A3) or the washers.
Notes:
!
On some engines the viscous damper is fitted to
the rear of the pulley.
! If a clamp ring with a chamfer on the outside edge
of the ring is used, ensure that the chamfer is
towards the damper when the ring is fitted. Clamp
rings may be fitted to viscous or plate dampers.
Apply POWERPART Retainer (oil tolerant) to the
cap screws (A4) for the clamp ring and tighten the
cap screws gradually and evenly to 35 Nm (26 lbf ft)
3,6 kgf m. For viscous dampers fitted with M12
setscrews tighten the fasteners to 75 Nm (55 lb ft)
7,6 kgf m.
Caution: Do not use a degreasing solution.
2 Clean thoroughly the nose of the crankshaft, the
bore of the pulley and the tapered rings components.
Do not expand the tapered rings.
3 Put the pulley on the crankshaft with the key
engaged and push the pulley towards the rear.
4 Fit the spacer (B1), then the inner ring (B2) and
then the outer ring (B3). Ensure that the ring gaps are
not aligned.
Caution: It can be very difficult to remove the pulley
if the tapered rings are not fitted correctly.
5 Lubricate lightly the "O" ring (B5) and the threads
and the thrust faces of the setscrews with clean
engine oil. Put the thrust block (B4) and setscrews in
position.
6 While the pulley is pressed to the rear, tighten the
setscrews gradually and evenly to 115 Nm (85 lbf ft)
11,8 kgf m. Apply the torque again to ensure the
pulley is fully tightened.
7 Fit the drive belts, see operation 24-3.
