e.
Variable Speed Pulley.
Every six months, the variable speed pulley
unit should be removed. It should be washed and cleaned with solvent. Then
it should be reoiled and installed.
The pulley shaft bearings are
lubricated from an oil cup (figure 37 on the following page) in the shaft
end.
The center sheave, which floats sideways as well as rotates, is
lubricated by a wick which is immersed in oil which travels through the
hollow shaft from the oil cup. Check to be sure the center sheave of the
pulley is free to shift sideways. The faces of the variable speed pulley
should be checked for scoring which could damage the belts.
