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.
