9a-3: Check the cylinder by feeling the shaft of the
cylinder and pulling up and down on the left
treadle. If the cylinder shaft moves in and out of
the cylinder body by more than an 1/8th inch (3.2
mm), then the cylinder will need to be replaced.
9a-4: If the problem is not in the cylinder, then check the
hardware at the following locations and tighten as
necessary:
a) On the rod-end entering the cylinder, the jam
nut should be tight to the rod-end, and there
should only be 2 or 3 threads showing on the
opposite side of the jam nut. This insures that
the rod-end is fully engaged in the cylinder.
b) The connection between the rod-end and the
dependency weldment. See Figure A-6. Tighten
as necessary.
c) The connection between the dependency and
the rod-end on the opposite (right) side (see
Figure A-4 and A-5).
d) The center bolt at the center of the dependency
weldment (see Figure A-6).
e) Check both the horizontal and the vertical bolts
connecting the cylinder to the coupler and the
coupler to the weldment of the pan. The bolts
should be torqued to 75 ftlbs (105 Nm). See
Figure A-7.
