c. Frame Tilt or Stabilizer Cylinder Internal Cleaning
1. Remove all hydraulic fluid, dirt and debris from the
inner surface of the cylinder.
2. Discard all seals, backup rings and O-rings. Replace
with new items from a complete seal kit to help
ensure proper cylinder function.
3. Clean all metal parts with an approved cleaning
solvent such as trichlorethylene. Carefully clean
cavities, grooves, threads, etc.
d. Frame Tilt Cylinder Inspection and Repair
In general, inspect all parts for wear, damage, etc. If inner
surfaces of the cylinder (1, Fig. 9– 68) do not display an
ultra-smooth, polished finish, or are damaged in any way,
replace the damaged part. Most often, dirty hydraulic
fluid causes failure of internal seals and damage to the
polished surfaces within the component.
1. Check that the rod weldment (16, Fig. 9– 68) is
straight. If the rod is bent, install a new rod.
2. Inspect the inside of the tube (2) for scoring and other
damage. If the tube is damaged, replace it with a new
tube.
3. Remove small scratches on the rod or inside of the
tube with very fine grit emery cloth. Use the emery
cloth in a rotary motion to polish out small
imperfections in the metal
4. Remove any burrs from components with a fine file.
Clean the parts with trichlorethylene after repair.
