If the pump is fitted with a Constant Level
Oiler type "ADAMS", no adjustment of the oil level is
possible.
5.2.4.2 Adjusting of DENCO Constant Level Oiler
If the pump is fitted with a Constant Level Oiler type
„DENCO“, the correct oil level has to be checked after
fitting the pump! Dimension a is the distance from the
centerline of the pump to the minimum oil level (marks
at the bearing housing).
1 Denco Oiler 2 lock nut 3 adjusting sleeve
4 oil sight glass 5 oil drain 6 distance sleeve
a) The oil level may be „fine tuned“ by turning the
adjusting sleeve (3) and finally locked into
position by tightening the lock nut (2). To
replenish, the reservoir and adaptor (1) may be
removed by sliding it out of the body, removing
the adaptor and fill the reservoir. Fully reinserting
the adaptor / reservoir into the body ensures the
previously adjusted oil level is maintained. The
oiler is equipped with an overflow tube to avoid a
rise of the oil level. This is necessary to maintain
a constant level in an oil bath lubrication system,
where an oil mist is used as primary lubrication.
The oiler is preadjusted with the distance
sleeve [6], therefore no adjustment is required
anymore.
b) Additionally you can check the correct oiler
adjustment by an oil sight glass (correct oil level
is the middle of the oil sight glass).
