Type of grease:
TECO motors can utilise different types of grease including Shell Gadus &
Mobil Polyrex EM Grease which has been selected based on the proposed
application.
Please check on the lubrication nameplate to confirm the type of grease
installed. Please use identical grease when servicing or alternatively
lubricants of different brands that have been established as being
equivalent in the areas of composition, physical properties and thickeners.
7.1.7.
Amount of grease replenishment:
Amount of grease replenishment depends on the type, size and construction
and the bearings. For the maximum quantity used in one replenishment of
each bearing, as a guide, please refer to Table 4.
Please refer to lubrication nameplate fitted and follow the recommended
quantity stated.
7.1.8.
Key points to note with grease filling:
Filling method for grease relief type bearing.
Use a good quality grease gun to pump grease through the grease nipple
into the bearings. The old contaminated grease is forced to drain out of the
discharge chute. While greasing it is recommended that the greasing
procedure is undertaken whilst the motor is running. The discharge outlet
may not be visible on some models, grease should be pumped in at the
recommended quantity and the sound of bearing should return to normal.
It is advisable to grease when the motor is operating as old grease is
expelled more easily.
