7.3 Regular oil analysis
Oil analysis are not intended as a substitute for
the oil change intervals but – apart from a
possible reduction of maintenance costs and as a
form of preventive maintenance – they take into
account the increasing environmental awareness.
Advantages of an oil analysis
•
Extension of the oil change intervals under
standard or light-duty operating conditions.
•
Minimum wear of high-quality components with
optimum use of the lubricants.
•
Periodic laboratory analyses enable an early
detection of imminent damage.
•
Repairs performed before they actually
become absolutely necessary help prevent
serious and unexpected damage.
•
Resulting damage will also be prevented.
How often should the oil be analyzed?
Regular oil analysis will indicate any developing
trends regarding the state of the oil and the
machine. The oils should be analyzed at the
following intervals:
•
Hydraulic oil: 1,000 running hours
•
Transmission oil: 500 running hours
•
Engine oil: 100 running hours
Based on the first results, the laboratory
recommends the interval for the next sampling.
Ask your Terex dealer for an information booklet
detailing the scope and procedures of the oil
analysis.
