Check oil level, it should be at bottom of hole
threads.
If oil level is low, check impeller shaft housing for
leaks. A pressure test must be performed. See

To check oil condition, insert a wire through oil lev-
el hole then withdraw. A whitish oil indicates wa-
ter contamination.
This may involve defective impeller shaft seal

If everything is correct, apply Loctite PST 592 on
plug and reinstall it on cover. Properly reinstall re-
moved parts.
