Sources of Copper in Oil
Typical sources of copper within engines include wrist pin bushings, thrust washers, oil pumps, governors,
valve train bushings, cam bushings, oil coolers and bearings. Copper can also be an antiwear additive in some
oils. Additionally, high copper readings may occur during the run-in of a new engine (say, after 500 to 1000
hours of service) and when changing from one brand of oil to another.
Getting a Handle
on Drums
Proper handling of drums is important.
Drums aren't designed to be bounced or
dropped. Full drums weigh approximately
450 pounds, while empty drums weigh
around 36 to 38 pounds. A pail of oil weighs
about 40 pounds.
Gearbox Magnets Are Effective
In enclosed gear drives with either splash or circu-
lation systems, a magnetic plug or magnetic filter will
help collect harmful wear debris. For splash systems, use
a magnetic plug or a magnet at the bottom of the case.
For circulation systems, a magnetic filter can be used.
Removing wear debris can help extend oil and machine
life. Wear debris can also be examined upon removal for
troubleshooting purposes. ML
