INSTALLATION & MAINTENANCE GUIDE

9.2 MOTOR BEARINGS LUBRICATION
Motors which have been supplied by Renold Gears will have bearings pre-filled with a high quality
Lithium-based grease.
Motor sizes D71 to D112 are provided with shielded/sealed bearings, which have been pre-filled and
greased-for-life by the bearing manufacturer. Motors with sealed bearings and no re-lubrication system
require no maintenance apart from noise and temperature checks and the checks stated in Section 9.1.
10. STORING THE GEAR UNIT
Gear units which are to be stored or left inactive for long periods of time should be adequately protected,
particularly those units situated on exposed sites and/or operating in corrosive or salty atmospheres.
The following precautions will generally be adequate for protecting the unit, but advice concerning the
protection of particular units can be given if required.
10.1 SHORT TERM STORAGE (UP TO 12 MONTHS)
I.
The location should be free from vibration, otherwise brinelling could take place, particularly between
bearing rolling elements and raceways, leading to noisy operation and early failure in service.
Wherever possible, the shafts of the unit should be rotated at least once a week, by hand if necessary,
to prevent brinelling.
II.
All external finish machined and unprotected surfaces should be spray coated with a anti-corrosion
rust inhibitor.
III.
After spraying, all shafts should be wrapped in anti-corrosion rust inhibitor paper.
IV.
Where the unit is empty of oil, spray the gearcase interior with rust preventative oil, which is
compatible with the recommended lubricant.
V.
Where the unit is filled with oil, operate at full speed once per month for not less than 10 minutes, to
ensure that all of the internal components receive a liberal coating of oil.
10.2 LONG TERM STORAGE (FROM 12 MONTHS UP TO 2 YEARS)
I.
The location should be free from vibration, otherwise brinelling could take place, particularly between
bearing rolling elements and raceways, leading to noisy operation and early failure in service.
Wherever possible, the shafts of the unit should be rotated at least once a week, by hand if necessary,
to prevent brinelling.
II.
Apply Denso paste and tape to all external finish machined and unprotected surfaces, including shaft
extensions, ensuring full coverage to lip of oilseal.
III.
Completely fill the unit with oil, ensuring complete submersion of all internal components. When the
unit is returned to service, drain and refill with new lubricant to the correct level (Sections 6.4 & 6.5).
Gear units can be prepared by Renold Gears for long term storage provided that this requirement is
stipulated on the order before delivery. Gear units will not be filled with oil, therefore the interior of the
unit would be sprayed with rust preventative oil.
11. SPARE PARTS
Information relating to spare parts can be obtained from the distributor of the unit.
