ENG
RA - OVERRUNNING CLUTCH.
This device prevents transmission of inertial loads from implement to the
tractor during deceleration or stopping of the PTO.
Keep clear of the implement until all parts have stopped moving. Lubricate
every 50 hours of use and after storage.
SA - RATCHET TORQUE LIMITER.
This device interrupts the transmission of power when the torque exceeds
the setting.
Immediately disengage the PTO when ratcheting sounds are heard.
Lubricate every 50 hours of use and after storage.
LB – SHEAR BOLT TORQUE LIMITER.
This device interrupts the transmission of power by shearing a bolt when the
torque exceeds the setting.
Replace the sheared bolt with the same diameter, length and grade as the original.
Lubricate the LB limiters with grease fittings at least once every season and after a
period of disuse.
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.
FFL – 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.
FFF - FRICTION TORQUE LIMITER
Limits torque transmission to the setting value. Do not change spring
compression as this will modify the device setting.
The torque setting of friction torque limiters FFL and FFF is adjusted by
increasing or decreasing the height “h” of the spring.
To increase / reduce the torque setting, screw / unscrew each of the eight nuts
by 1/4 of turn and check for proper operation. Repeat the procedure if necessary.
Avoid excessive tightening of the bolts - implement, tractor, or driveline damage
may occur.
