Usage:
The mineral oils listed in this shop standard specification meet the minimum requirements given in DIN 51517 T.3 for CLP oils. They contain constituents that improve corrosion protection and ageing resistance as well as reduce wear in the mixed friction range (extreme pressure additives). When subjected to normal FZG testing A/8, 3/90 to DIN 51354 T.2 a breakdown-load stage of min. 12 is achieved. When subjected to a FZG micro-pitting test as per FVA No. 54/I-IV these oils reach the micro-pitting (frosting) load carrying property category "high" (SKS 10) or at least "medium" (SKS 9).
Other oil brands meeting or exceeding CLP requirements are included such as hydraulic oils HLP or synthetic oils HC.
LSN Specification 935 1410 describes ISO viscosity categories. Low-viscosity oils are almost exclusively needed for use with multiplate brakes. They have been tested by the multiple-plate manufacturer for compatibility and friction behavior.
Not all of the lubricants listed in this shop standard are suited for any conceivable application. For that reason, L+S Groups LS 1, LS 2, LS 3 were established.
NOTE: The Design Department hast to specify the required L+S group! This group will be indicated in the operating manual and/or on the nameplate. When selecting an oil brand care must be taken to ensure that all requirements of a given L+S Group are met. In the event an oil meets requirements of additional L+S Groups this lubricant can be used as well.
LS 1: Aggravated FZG test:
Even when FZG tested under aggravated conditions (test A / 16,6 / 90-double peripheral speed) these oils have reached the properties of breakdown-load stage 12.

LS 2: Lube oils compatible with multiple plates:
These oils have been tested for friction characteristics and can be used with friction value impairment in gears fitted with wet multiplates.
The maximum viscosity with wet multiplates has been restricted to ISO VG 220 because higher viscosity values negatively influence actuation.

LS 3: Fully synthetic oils (polyalphaolefins PAO):
When replacing mineral oil by polyalphaolefin-based oil 5 to 10% of the mineral oil are allowed to remain in the casing after draining. Mixing both lube oil types is perfectly allowable if this mixing ratio is observed.
NOTE: However, PAO oils tend to foaming when mixed with residues of preservation oil as used by L+S. Therefore, prior to initial filling of a preserved gearbox the unit must either be flushed out or a mineral oil is to be used as running-in oil.
