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.
FFV - 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 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.
Friction clutches may become hot during use. Do not touch! To avoid the
risk of fire keep the area around the clutch free of inflammable material and
avoid prolonged slipping of the clutch.
ASSEMBLY AND DISASSEMBLY OF THE SHIELD
DISASSEMBLY OF THE SHIELD
Press the cone downwards and disengage the tabs by exerting pressure
with a screwdriver.
Open the ring to completely disengage the shield tube.
ASSEMBLY OF THE SHIELD
Grease the bearing groove on the inner yokes.
Insert the shield tube, aligning the slots with the protrusions on the bearing.
Insert the cone. aligning the grease fitting with the bearing grease boss.
Engage the two parts with a forceful maneuver and apply pressure.
Check that the three tabs are perfectly engaged by tapping lightly.
