Cylinder Shaft Protection
The steps summarized below should be followed
when protecting chrome plated shafting on
equipment:
• Position the equipment as it will be stored, and
identify all the exposed portions of the chrome
plated shafts.
• Clean dirt and dust from the exposed portions
of the shafting using a dry cloth or a cloth which
has been dampened with an appropriate solvent.
• Prepare a mixture of 60% oil-based rust inhibitor
and 40% Kerosene. Apply a thin coating of this
mixture to the exposed surfaces of the chrome
plated shafting. No. 1 fuel oil may be substituted
for Kerosene. A cloth dipped in the mixture can
be used to apply the coating.
• Inspect the shaft surfaces after six months and
apply additional corrosion preventative mixture.
• If the equipment is to be moved and then stored
again for an extended period of time, the steps
above should be repeated for all shafts that were
stroked during the move.
• Before retracting the cylinders the protective
coating should be removed, to prevent fine
sand and dirt that has accumulated in the
coating, from damaging the shaft seal. Under
no circumstances should sandpaper or other
abrasive be used to clean the surfaces.
Plastic or copper wool in combination with an
appropriate solvent will remove most of the dirt.
Dirt in the hydraulic system could damage
O-rings, causing leakage, pressure loss
and total system failure.
