LUBRICATION POINTS
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.
On all hoists with a check plug in the drum, the fill plug shall be directly on top of the hoist, and the check plug
level.
All grease fittings are SAE STANDARD unless otherwise indicated. Grease nonsealed fittings until grease is
seen extruding from the fitting. One pump of a standard one pound (0.45 kg) grease gun equals one ounce (28
grams) of GAA.
Over lubrication on non-sealed fittings will not harm the fittings or components, but under lubrication will definitely
lead to a shorter lifetime.
On sealed U-joints, care must be exercised to prevent rupturing seals. Fill only until expansion of the seals first
becomes visible.
Unless otherwise indicated, items not equipped with grease fittings, such as linkages, pins, levers, etc., should be
lubricated with oil once a week. Motor oil, applied sparingly, will provide the necessary lubrication and help
prevent the formation of rust. An Anti-Seize compound may be used if rust has not formed, otherwise the
component must be cleaned first.
Grease fittings that are worn and will not hold the grease gun, or those that have a stuck check ball, must be
replaced.
Where wear pads are used, cycle the components and relubricate to ensure complete lubrication of the entire
wear area.
The following describe the lubrication points and gives the lube type, lube interval, lube amount, and application
of each. Each lubrication point is numbered, and this number corresponds to the index number shown on the
Lubrication Chart.
