Working preparation
Reducing the cardan shaft length
If it is necessary, cut similar parts of the male and female shaft as well as the protection
covers. But before cutting the shaft, verify all possibilities of usage without reducing its
length.
The length adjustment will be done when the distance between the equipment and
tractor do not allow coupling. Proceed as follows:
• First of all, disassemble the protection covers.
• Cut the hub and the solid bar (male and female) in the
desired measures. In order to do so, couple half of the cardan
in the tractor and half in the equipment, placing the semi-
cardans in parallel and in several operating positions. Then,
determine the correct length and mark the cutting area.
• It is important to give finish working in the cut parts.
For this purpose, use a filer. Soon after, remove the filing and
lubricate the 'male' with a fine layer of grease.
• Decrease the length of both protective covers, using
the cut tubes as a measure and clean the cut residues.
• Then, assemble the cardan shaft, according to the
instructions on the next page.
NOTE
The contact surface between the hub and the bar shall not be smaller than
1/3 of the total length.
• When using another tractor to work with the spreader, verify the length of the cardan
shaft again.
• The chains of the protection covers should be fastened in the equipment and in the
tractor, so that they will not get loose during maneuvers.
