Maintenance
A full maintenance schedule is provided in the operators book and this should be
followed to ensure reliable operation of the combine.
When checking belt tensions there are three main types of tensioner that are fitted
to LEXION Combines:
1. End to end guides – Correct
tension is achieved when the ends
of “D” are end to end. To tension
the belt, slacken nut K from M and
wind M in a clockwise direction
until the ends of D are met then re
lock nuts M and K. If the belt
needs removing please consult
section 14 of the operators
manual.
2. Centre to centre guides – work in exactly the same way as the end to end tensioners
except the belt is at the correct tension when the tabs overlap the full length of the
recessed part of the tabs.
3. Gold tube type – Under the correct tension
the gold tube should be just able to turn by
hand, if loose it will need tightening. To tension
slacken Nut K slightly, tighten “R” until it meets
the gold tube. It should still be possible to
rotate the tube by hand with a firm grip. Then
lock the assembly with the nut K.
