9.4 Hydraulic oil integrity is Critical
The new OLYMPIA Millennium H is a genuine hydrostatic drive machine relying on hydraulic
fluid as the key element in power transfer rather than conventional mechanical means with a
transmission & differential. Consequently the performance and longevity of the system relies
on the integrity of the fluid.
Not only does the hydraulic fluid drive the wheels it also lubricates and cools each of the
precision components within the drive system. The quality and quantity of the hydraulic fluid
is critical. I must be maintained and kept free of contaminants and within designed operating
parameters to provide the longest possible life for the pumps & motors.
Beware of Hydraulic Oil Contamination
Oil contamination can be in three forms; solid, liquid, or gas which generally relates to
dirt, water or air. A high concentration of any of these contaminates can degrade machine
performance and reduce component lifespan resulting in premature failure. The onboard filters
remove solid particulate only and are designed to primarily “maintain” a clean system, not to
“clean-up” a system. It is up to you to eliminate contamination during any service work that
involves the addition or changing of the hydraulic oil.
9.5 System Temperature
Hydraulic oil will break down and loose lubrication qualities in high temperature conditions.
It is important to monitor temperatures regularly in the system as a proactive measure to
identifying a potential problem before it results in a premature or even catastrophic failure.
In addition to the on-board temperature monitors, we suggest you use an infrared temperature
gun to first establish a baseline by measuring and tracking the reservoir temperature and
each motor on a weekly basis. The machine should be pulled from service if the reservoir
temperature reaches 60 degrees Celsius as there will be insufficient lubrication for the
bearings.
