BALDWIN BD103 FILL PROCEDURE | |
Do not pre-fill new BD103 oil filters by forcing oil through the outlet | |
|
Occasionally, we receive a used BD103 oil filter where the by-pass element has been exploded outward due to a reverse flow condition. If reverse flow occurs, the by-pass element outer wrap or the by-pass media may rupture and small portions of wrapper and/or media may migrate downstream, possibly lodging in a critical engine component or oil passage. This could lead to possible engine damage.
Recent laboratory testing has been able to reproduce the exploded element appearance. This was accomplished by pre-filling the complete filter through the by-pass element grommet using a pressurized lubing system. |
The by-pass filter in the BD103 is designed for outside-in flow. When oil flows in this direction, the filter is strong enough to maintain necessary structural integrity. This is not the case if the flow direction is reversed to inside-out flow. The BD103 filter must be pre-filled by pouring oil into the end of the entire filter. If a pressurized lubing system is used to fill the filter, it must not be directed through the grommet of the by-pass element (see illustrations below).
This same procedure should be followed with other similar Baldwin products containing an internal by-pass element such as the Baldwin BD324. |
