SECTION IV
LUBRICATION
A "Trico" Oiler is normally furnished with the pump unless otherwise specified.
4.1 Preparing Bearing Housing
Before filling the bearing housing reservoir, flush out the housing thoroughly with safety solvent
and a leading grade of flushing oil, compatible with the lubricating oil that will be used. The
reservoir is to be filled to appropriate level as illustrated in section 4.6.
D1: oiler connection with slinger lubrication C1: overflow plug with slinger lubrication
D2: oiler connection with oil ring lubrication C2: overflow plug with oil ring lubrication
CONSTANT LEVEL OILER LUBRICATION
The oil level must be maintained at the correct level: oil lack may cause overheating and failure of
the bearings, while exceeding the correct level can result in leakage from the labyrinth seals. The
constant level oiler can be adjusted by changing the height of the cross arms which support the
glass reservoir, as illustrated for TRICO oiler in section 4.6.
4.2 Inspection
Inspect the oil level in the bearing housing at least once a day. Inspect the condition of the oil at
least weekly. Oil is always subject to gradual deterioration from use and contamination from dirt
and moisture which is the cause of premature bearing wear.
4.3 Replenishment
Replenish the oil in the oiler as required. More frequent replenishment at high temperatures may
be required.
