Perkins Phaser Series - Crankshaft Pulley and Damper

CRANKSHAFT ASSEMBLY 14
Crankshaft pulley and damper
To remove and to fit - six cylinder
engines 14A-01B
Consumable products:
POWERPART Retainer (oil tolerant)
Caution: A viscous damper (C2) should be
renewed if there is impact damage to the outer
casing or if there is leakage of the viscous fluid
from the cover plate. Check the area around the
holes for the damper fasteners for damage.
To remove
1Remove the drive belts, operation 23A-04.
Warning! The crankshaft pulley and damper
assembly is heavy and must be given support
before removal.
2 Release the fasteners which secure the clamp
ring (C3) for the damper to the pulley, if one is
fitted, and remove the damper.
3 Remove the three setscrews and the thrust block
(B4). If the pulley is not free, do not use an
extractor to remove the pulley. Hold a wooden
block against the inner hub of the pulley and with a
hammer, lightly hit the wooden block towards the
rear (A) to loosen the tapered rings.
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 (C1). Fit the clamp ring
(C3) 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.
