Swing Gearbox and Brake Oil
Check Swing Gearbox oil level:
The oil in the gearbox and brake sections is recommended
to be changed after first 50 hours of operation and every
1000 hours or 6 months of usage. The capacity is 0.71 liter
(0.75 qt).
1. Examine the used oil for signs of significant metal
deposits.
2. Fill the swing gearbox with the appropriate amount and
type of oil and then replace plug and vent. See
“Lubrication” on page 5-3 of this manual.
Gearbox oil level inspection is achieved by removing the
gearbox fill/vent plug and visually inspecting the oil level.
Maximum oil level is to be 1” below the port for this gearbox
with of gear lube oil.
Gearbox lubricants are satisfactory for standard operation in
temperatures from -23° C to 82° C (-10° F to +180° F). For
operation outside this range, contact Manitowoc Crane Care
for recommendations.
HYDRAULIC OIL RESERVOIR LEVEL
The hydraulic oil reservoir has a sight gauge located on the
side of the reservoir. This sight gauge has a decal beside it
that indicates a “full” level and an “low oil” level. The oil
required to bring it from the “low” line to the “full” line is 5
gallons. Do not fill the reservoir above the “full” line. The oil
level should be checked with the crane parked on a level
surface in the transport condition (all cylinders retracted and
boom stowed) and the oil cold.
If the oil level is too low, add the recommended hydraulic oil
until the oil level is even with the upper mark. If the oil level is
high, drain oil until the oil level is even with the upper mark.
Hydraulic Filter Replacement
The filter is mounted in the oil reservoir, and is a replaceable
element type.
The filter must be serviced with National Crane replacement
elements at recommended intervals to assure the warranty
remains in effect. See the Service Manual for filter
replacement instructions.
Wire Rope Lubrication
Wire rope is lubricated during manufacture and the lubricant
applied does not last the life of the rope. The wire rope must
be lubricated as part of a regularly scheduled maintenance
