FRICTION TORQUE LIMITERS
When installing the device or after a storage period check the operation of the
friction plates:
• release the springs • rotate the clutch while immobilizing the PTO on which is
installed • restore the spring compression to the original value. Following seasonal
use, release the springs and store the clutch in a dry place. Check the condition
of the friction plates and restore spring compression before using the clutch. If the
clutch overheats due to frequent or prolonged slipping, consult your equipment
dealer or your local Bondioli & Pavesi representative.
FV – FRICTION TORQUE LIMITER.
The torque transmitted to the implement is limited by allowing the clutch
plates to slip relative to each other.
Torque peaks or short duration overloads are limited when the clutch is used and
adjusted properly.
It can be used as an overload clutch, or to help start implements with high inertial
loads.
The torque setting is adjustable by adjusting the working height of the spring.
The edges of the linings and plates are exposed in an FV clutch.
The torque setting is adjusted by increasing or decreasing the height “h”
of the springs. To increase/decrease the torque setting tighten/loosen the
eight nuts by 1/4 of a turn and check for correct operation. Repeat the procedure if
necessary. Avoid excessive tightening of the bolts - implement, tractor, or driveline
damage may occur.
FT – FRICTION TORQUE LIMITER.
The torque transmitted to the implement is limited by allowing the clutch
plates to slip relative to each other.
Torque peaks or short duration overloads are limited when the clutch is used and
adjusted properly.
It can be used as an overload clutch, or to help start implements with high inertial
loads.
The FT has a metal band around its circumference.
The bolts should be tightened until the metal band around the circumference of
the clutch barely touches the spring. Avoid excessive tightening of the bolts -
implement, tractor, or driveline damage may occur.
Clutches supplied with the Spring Release System allow quick and easy
checking and maintenance of the clutch without disassembly and make it
possible to minimise spring pressure on the plates during periods of disuse.
Friction clutches equipped with the Spring Release System are supplied with
an additional instruction sheet. Read this information for proper use of the
Spring Release System.
FFV - FRICTION TORQUE LIMITER
Limits torque transmission to the setting value. Do not change spring
compression as this will modify the device setting.
