Checking Foreline Pump Oil Level and Condition
NOTE: The Saturn 2000 Maintenance Tutorial on CD-ROM provides viewing
maintenance procedures on computer screen.
Refer to Pump Maintenance
Section.
The oil level and condition should be checked with the pump switched off, but still
warm.
1. The oil level should be between the maximum and minimum levels on the
sight glass. If the oil level falls below the minimum level, gradually add more
oil (88-299517-00) through the filler port until the oil level is centered
between the maximum and minimum levels. A funnel may be helpful.
NOTE: Some Saturn 2000 systems use similar but different models of
forepumps. The maintenance procedures are similar but the location and
appearance of some components are different. Refer to the pump manual for
details.
2. The pump oil should be clear and light amber in color.
•
If the oil becomes cloudy, purge it as described in Purging Foreline
Pump Oil.
•
If the oil becomes thick, dark in color and has a burnt smell, change it as
described in Changing Foreline Pump Oil.
