Version 125

- Insert the new oil guards and O-Rings on the mobile half-

pulley.

- Install the half pulley on the bushing using the specific tool

- Check that the pins are free from wear and reassemble into

the relative slits.

- Replace the collar to close the servo-system.

Using a bent beak greaser, lubricate the driven pulley unit

with about 6 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 required to prevent the presence of grease

beyond the O-rings.

N.B.

THE SERVO-SYSTEM MAY BE LUBRICATED BOTH WITH BEA-

RINGS MOUNTED OR UPON THEIR REPLACEMENT; THE IN-

TERVENTION CARRIED OUT DURING THE BEARING OVER-

HAULING MAY BE EASIER
