Slip clutch
Maintenance
The slip clutch (A) is assembled both in the gearbox (B )and in the cardan shaft (C),
being also assembled in the metering box shaft. It is designed to slip, absorb operation
loads and to protect the drive shaft. The slip clutch is factory fitted with a specified torque,
in order to protect the tractor and 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
(D). Do not assembly the cardan shaft without its protection cover (E).
Proceed the assembling process and be sure that the slip clutch terminal totally enter
in the grooves of the metering box shaft.
IMPORTANT
Tighten the nuts (F) from the compression spring
(G) that has a length of 28 mm to adjust the slip clutch
(See details in the figure).
The slip clutch must be checked periodically and
adjusted to compensate the friction of the set. The
plates (H) have a thickness of 5 mm when they are
new. Replace them as soon as they get to 1.5 mm. If
the rotary cutter stays inative for a long period or in a
humid place, carry out the verification on the next page
to be sure that the plates and flanges are not oxidized.
Things that must be checked weekly in the slip
clutch plates: the presence of oil or grease and wearing/
humidity that may cause corrosion of the plates.
The plates (H) must be replaced as soon as they get to a thickness of 1.5
mm or before, if they show greater damages. In order to do so, loosen
up the nuts (F) and disassemble the slip clutch.
