Basic oil specifications
Oils should be selected on the basis of the following parameters:
• viscosity under nominal operating conditions
• additives
The oil must lubricate the bearings and the gears, bearing in mind that these components work in the same box, but under
different operating conditions. We will look at these parameters one by one.
VISCOSITY
Dana Incorporated recommends gear oils with EP additive (Extreme Pressure) and 40° VG viscosity index of at least 150 cTS.
Oil viscosity at operating temperature must always be greater than 50cTS.
Viscosity values under 50cTS could shorten the running life of gears and bearings.
The table below lists recommended oils for various operating oil temperatures in the gear unit. For temperatures above 80°C or
for huge swings in temperatures, synthetic lubricants are recommended.
ADDITIVES
In addition to standard anti-foaming and anti-oxidant additives, it is important to use lubricating oils with additives that have EP
(Extreme Pressure) and anti-wear properties, and that conform to ISO 6743-6 L-CKC or DIN 51517-3 CLP. Clearly, the slower
the gear unit speed, the stronger the EP characteristics the product must have. Not to be overlooked is that fact that the che-
mical compounds replacing hydrodynamic lubrication are formed to the detriment of the original EP load. In low speed, high
load applications, regular maintenance intervals must be respected to prevent the oil losing its lubricating properties.
Checking oil with non-forced lubrication
If the gear unit is fitted horizontally, to ensure proper lubrication, the oil level should be at the centre (see fig. 24).
NOTE:
Dana Incorporated gear units are not filled with oil when supplied therefore users should select an appropriate lubricant
in accordance with the table in section "Lubricant table p. 30".
