REGULATOR ASSEMBLY

After removing the sliding flange from the fixed flange shaft,

position the latter on the removal tool in order to lower the upper

main bearing (11).

Lower the upper main bearing (11) to be able to remove the

retaining ring (12) with a flat blade screwdriver.

Rise the sliding flange slowly to remove it. Avoid dropping parts if

removing is performed with a table press.

According to the pulley’s adjustment, please note that

you must carefully observe the quantity and position of the

spacer washers (5-6-7) and (9-10) to avoid modifying the

initial yield of the pulley.

Cleaning the sliding parts with a degreaser is indispensable

to maintain optimum performance.

Inspection
