let the water out after the check, especially if
freezing temperatures are expected. Failure to
replace the rod packings when they need it will
result in contaminates from the water box,
including water, entering the hydraulic oil at the
packings and wearing on the rods, cylinder
tubes, guide bushings, pistons and the piston
rings. The material that gets worn off of the
above mentioned items also becomes
contamination, accelerating the wear. Left
unchecked, this wear will totally destroy a
differential cylinder. Normally, you will be due
for new packings after 1 to 2 years.
7. Each day you should visually inspect the bolts on
the rubber rams as well as those on the S - tube.
Notice if there is any play. If you see something
suspicious, shut off the engine, put the key in
your pocket, remove the hopper grate, and
inspect with a wrench. If you find that they are
loose, tighten with a torque wrench to the torque
specifications found in the
Appendix section of
this manual. Don’t forget to replace the hopper
grate before using the machine.
8. Grease the pivot shaft bearing and outlet
assembly (Figure 33). This can be done on the
job as described in the
Operation section of this
manual.
9. Visually inspect the unit for damage or leaks
each day. Repairs should be made before the unit
is operated.
10. Once a day you should check your maintenance
checklist to see if any scheduled maintenance is
due.

Grease relief
valve
The Grease relief valve above is
designed to prevent over greasing
which could prevent valve movement.
The decal below points out that it is
indeed a relief and not a broken zerk.
If it is replaced with a grease fitting
the pressure from excess grease will
prevent the valve from moving.
