Refitting the driven half-pulley bearing
- Support the pulley bushing adequately from the threaded side using a wooden surface.
- Fit a new roller bearing as shown in the figure.
- For the fitting of the new ball bearing, follow the example in the figure using a modular punch.

Refitting the driven pulley
- Insert the new oil seals and O-rings on the movable half-pulley.
- Lightly grease the O-rings "A" shown in the figure.
- Fit the half-pulley over the bushing using the specific tool.
- Check that the pins are not worn and proceed to refitting them in their slots.
- Refit the torque server closure collar.
- Using a curved-spout grease gun, lubricate the driven pulley unit with approximately 6 grams of grease. Apply grease through one of the holes in the bushing until it comes out through the hole on the opposite side. This operation is necessary to avoid the presence of grease beyond the O-rings.
N.B.
THE TORQUE SERVER CAN BE GREASED WHETHER WITH BEARINGS FITTED OR WHEN THEY ARE BEING REPLACED; UNDERTAKING THE OPERATION WHEN THE BEARINGS ARE BEING SERVICED MIGHT BE EASIER.

Support the driven pulley spring compressor specific tool with the control screw in vertical axis. Arrange the tool with the medium length pins screwed in position "C" on the inside. Introduce the adapter ring No. 11 with the chamfering facing upwards. Insert the clutch on the adapter ring. Lubricate the end of the spring that abuts against the torque server closing collar. Insert the spring with its plastic holder in contact with the clutch. Insert the drive belt into the pulley unit according to their direction of rotation. Insert the pulley unit with the belt into the tool. Slightly preload the spring. Make sure that the clutch is perfectly inserted into the adapter ring before proceeding to tighten the clutch nut. Place the tool in the clamp with the control screw on the horizontal axis. Fully preload the spring. Apply the clutch fixing nut and tighten it to the prescribed torque using the special 46x55 wrench. Loosen the tool clamp and insert the belt according to its direction of rotation. Lock the driven pulley again using the specific tool. Preload the clutch return spring with a traction/ rotation combined action and place the belt in the smaller diameter rolling position. Remove the driven pulley /belt unit from the tool.
