Bearing temperature may rise above normal
immediately after lubrication, but should stabilize
within four to eight hours.
NOTE
Carver recommends replacing bearings if
removed from the shaft. If it is necessary to
reuse bearings that are in good condition,
use proper bearing replacement procedures
outlined in this section.
If applicable, lineshaft bearings should be lubricated
at fittings on baseplate near the discharge pipe. Use
the same grease and lubricate at the same time as
the ball bearing.
