The slip clutch is designed to slip, absorb operation loads and to protect the drive
shaft. It is factory fitted with a specified torque, in order to protect the combine harvester
and the equipment.
Before starting the assembly, be sure that the metering box shafts are clean, without
any ink and dirt. To facilitate the assembly, apply some grease in the grooves of the shaft.
Do not assemble the cardan shaft without its protection cover.
To adjust the slip clutch, tighten the bolts (A) from the compression spring, giving half
turns at a time.
The slip clutch must be checked periodically and adjusted to compensate the friction
of the set. The discs (B) have a thickness of 5 mm when they are new. Replace them as
soon as they get to 1.5 mm. If the equipment stays inative for a long period or in a humid
place, carry out the verification on the next page to be sure that the discs and flanges are
not oxidized. Things that must be checked weekly in the slip clutch discs: the presence of
oil or grease and wearing/humidity that may cause corrosion of the discs.

NOTE
- The discs (B) must be replaced as soon as they get to a thickness of 1.5 mm or before,
if they show bigger damages. In order to do so, loosen the nuts (C) and disassemble
the slip clutch.
