Lubrication of Replacement Bearings (Four bearing designs
only) When installing new bearings, it is necessary to repack
bearings with grease. Do this by forcing grease into the bear-
ings and “butter” both sides with grease so that the grease is
flush with the race. Use only Chevron SRI #2 grease. For out-
board tandem bearing installation, follow procedures packed
with each new bearing set. Remember, these bearings are
manufactured as a set to Spencer’s rigid specifications.
Motor Bearing Lubrication (Applicable to all)
Follow motor manufacturer’s recommendations. Some motors
equipped with sealed bearings are not intended to be re-lubri-
cated. There are, therefore, no grease or drain plugs on motors
of this type.
Flexible Coupling Lubrication
Gear type couplings must contain lubricant at all times.
Re-lubricate after checking alignment. Follow the coupling
manufacturer’s recommendations.
Lubricated couplings on machines shipped from Spencer have
been serviced with Texaco Coupling Grease (#1912). All couplings
should be re-lubricated prior to start-up.
To re-lubricate Sier Bath without disassembling coupling,
remove both lube plugs and position lube holes at 45˚ to hori-
zontal. Force grease into top hole until clean grease flows out
of opposite lower holes. Reinstall both plugs and wipe off all
excess grease. Re-lubricate every six (6) months.
Coupling Half Removal
Gear type couplings generally require the application of heat
and the use of a puller to remove.
