RT9130E-2 SERVICE MANUAL LUBRICATION
SURFACE PROTECTION FOR CYLINDER
RODS
Steel cylinder rods include a thin layer of chrome plating on
their surfaces to protect them from corroding. However,
chrome plating inherently has cracks in its structure which
can allow moisture to corrode the underlying steel. At typical
ambient temperatures, hydraulic oil is too thick to penetrate
these cracks. Normal machine operating temperatures will
allow hydraulic oil to warm sufficiently to penetrate these
cracks and if machines are operated daily, protect the rods.
Machines that are stored, transported, or used in a corrosive
environment (high moisture, rain, snow, or coastline
conditions) need to have the exposed rods protected more
frequently by applying a protectant. Unless the machine is
operated daily, exposed rod surfaces will corrode. Some
cylinders will have rods exposed even when completely
retracted. Assume all cylinders have exposed rods, as
corrosion on the end of the rod can ruin the cylinder.
It is recommended that all exposed cylinder rods be
protected using Boeshield® T-9 Premium Metal Protectant.
Manitowoc Crane Care has Boeshield® T-9 Premium Metal
Protectant available in 12 oz. aerosol cans by ordering part
number 9999101803 through the Parts Department.
Cylinder operation and inclement weather will remove the
Boeshield® protectant; therefore, inspect machines once a
week and reapply Boeshield® to unprotected rod
WIRE ROPE LUBRICATION
Wire rope is lubricated during manufacturing so that the
strands, and individual wires in strands, may move as the
rope moves and bends. A wire rope cannot be lubricated
sufficiently during manufacture to last its entire life.
Therefore, new lubricant must be added periodically
throughout the life of a rope to replace factory lubricant which
is used or lost. For more detailed information concerning the
lubrication and inspection of wire rope, refer to Wire Rope in
Section 1- Introduction in the Service Manual.
LUBRICATION POINTS
A regular frequency of lubrication must be established for all
lubrication points. Normally, this is based on component
operating time. The most efficient method of keeping track of
lube requirements is to maintain a job log indicating crane
usage. The log must use the engine hourmeter to ensure
coverage of lube points that will receive attention based on
their readings. Other lubrication requirements must be made
on a time basis, i.e. weekly, monthly, etc.
All oil levels are to be checked with the crane parked on a
level surface in transport position, and while the oil is cold,
unless otherwise specified.
On plug type check points, the oil levels are to be at the
bottom edge of the check port.
