How to Speed up Oil Changes
Use your circulation pump to speed up oil changes
in large circulation systems. Install a tee and two
isolating shut-off valves downstream of your circu-
lating pump. When draining your reservoir, connect
the hose to this tee and use your pump to move the oil
from your reservoir to the scrap oil truck. is is espe-
cially helpful for large, below-ground level systems.
Tip for Replacing Oil Filters
When replacing top-suspended spin-on or threaded canister-type filters, fill them with fresh oil before instal-
lation. is will reduce the amount of time that the engine or machinery undergoes dry start-up by having an
extra amount of oil available. In some cases, it could also prevent filter damage when a gush of high-pressure fluid
hits a dry element.
Pay Attention to
Your Oil Level Indicator
When rolling-element bearings are lubricated from oil held
in a sump, attention to the oil sump level indicator will not
only bring savings in terms of extended bearing life, but also
will lead to reduced bearing temperatures due to churning and
metal-to-metal contact resulting from possible oil starvation.
As a general rule, the lowest rolling element should be half
covered with oil when the bearing is stationary. is may seem
like a simple rule to observe, but it is surprising how often it is
completely overlooked.
