N.B.
O-RINGS ARE OF TWO SIZES. THE LARGE ONE IS INSTALLED ON THE MACHINING END RA-
DIUS, AT THE BASE OF THE HALF-PULLEY.
- Install the half-pulley on the bushing being careful
not to damage the top sealing ring during the in-
troduction.
- Make sure the pins and collar are not worn, re-
assemble the pins and collar.
- Using a bent beak greaser, lubricate the driven pulley unit with about 10 gr. of grease, this operation
should be carried out through one of the two holes into the bushing to obtain the exit of the grease from
the opposite hole. This operation is necessary to avoid the presence of grease beyond the O-rings.
