DRIVE BELT -- Figures 33 and 34
The belt tension is correct when belt D can be de-
flected 14 mm at Z when applying a force of 17 N.

U. Loosen bolts W and adjust pulley A and its
support slightly downwards [forming an angle of
approximately 35° with the straight line between
the two pulleys -- front pulley upper side and rear
pulley lower side (view from the rear)], so that a
clearance of 2 to 3 mm exists between both belt
halves. Retighten bolts W .

The belt tension is correct when the belt can be
deflected 5 mm when applying a force of 41 N
halfway between the pulleys at X .
Adjust with rod B after loosening bolts C.
Retighten bolts C.
NOTE:
Adjustments of the straw walker drive belt and
the straw walker intermediate shaft drive belt
