PULLEY COMPONENTS VISUAL CONDITION SUMMARY
LAGGING Some tiles chip off & broken, Replacement required.
SHELL
Visually in good condition, no cracks found on welding after NDT, shell thickness reading less than 3mm from its minimum
thickness, i.e. 10mm
SHAFT Bearing journal @ fixed end side badly damaged due to premature bearing failure, Replacement required,
HOUSING & BEARINGS Bearing outer race break into pieces and bearing balls out of the cage and seized to shaft, both Plummer block heavily corroded, Replacement required,
LOCKING ELEMENTS
Both Elements are in a FAIR condition, except for CORROSION
on the outer surfaces including bolts heads. However we recommended against re-using Locking Elements as the surface condition of the parts as well as grade and quantity of lubricant cannot be returned to the as supplied condition from the OEM. This means there is a significant risk that the correct assembly pressures will not be achieved. Locking Elements require replacement.

COUPLING Heavily corroded and seized to shaft, repair required and bolts to be replaced with new.
CRADLE
Though arrival steel cradle is in good condition but it is not suitable for this pulley, i.e. plummer block base not seating on
the cradle base, either we need to modify or manufacture cradle to suit.
