Two top pulleys:
check each pulley rotates freely and
there is not excessive free play in bush.
Push pulley to either side and lubricate the pin (spray
lubricant with extension nozzle) and rotate to work lube
into bush.
Ensure all bolts are tight.
4 Control-post bottom pulley:
create more slack in the wire
ropes: use a lifting device to raise non-control-post up a
further 200mm, and lower onto safety locks.
Check each pulley rotates freely and there is not excessive
free play in bush.
Push bottom pulley to one side and lubricate the pin
(with spray lubricant with extension nozzle), push pulley
to the opposite side and spray lubricate the other side.
Rotate to work lube into bush.
Ensure all bolts are tight

Wire Rope & Pulley Removal (see page 16, steps 1 to 7);
