SECONDARY TRANSMISSION SYSTEM 9 - 8
TORQUE LIMITER SYSTEM
DISASSEMBLY
o
Lightly loosen the 6 Allen bolts (part # 7 on the exploded
view of the torque limiter) in a criss-cross pattern.
o
The threaded aluminum disc (part # 3 on the exploded
view) can now be removed by hand.
o
After removing the threaded aluminum disc proceed to
removing the core, the pressure plates and the friction
plates. Next, remove the small Allen screws holding the
final pressure plate to the cog sprocket and remove the
pressure plates.
CLEANING
o
All of the torque limiter components should be clean
before reassembly. The parts can be cleaned using
brake cleaner.
INSPECTION
●
NOTICE:
Because so much dirt and dust accumulates inside the torque
limiter, it should be periodically cleaned and inspected.
◆
WARNING
After approximately 10 hours of use, it is necessary to
verify the torque of the 6 allen head screw ( part # 7 ) of
the torque limiter. The required torque for normal
operation is 6 N-m ( 55 lbf-in ).
o
Verify the friction plates (part # 6 ) to ensure that they
are not cracked or damaged. Replace if required.
o
Verify the pressure plates # 4 and # 5 to ensure they are
not scratched. If so then they can be repaired using a
fine sand paper or released.
o
Verify that the cog sprocket is not damaged. If
damaged, replace with a new one.
