3. Gear oil The lube oil specification for gears is based on API and SAE classification. The oil chamber in travel gears for double lifetime seal is filled with oil from the hydraulic system - see section 2. 3.1. Oil quality As a general rule, only oils meeting API - classification GL-5 may be used. 3.2. Oil viscosity The following oils must be used in travel gears, and are highly recommended for use in splitter boxes: Viscosity classification SAE 85 W - 140 EP For splitter boxes, oils of
Viscosity classification SAE 90 EP or SAE 80 W - 90 EP may also be used.
For the operation in extreme climatic conditions, such as in arctic regions or in extreme temperatures ranges, such as in slag applications, special oils may be approved if the prevailing ambient temperatures are known operations. 3.3. Lube oil for final drive - sealing chamber For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils. 4. Lube oil for support shaft bearing For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils. 5. Hoist gear oil - pipe layers As a general rule, the guidelines noted in the Operation and Maintenance manual and the winch manufacturer should be observed. For lubrication technical reasons, we recommend the use of Diesel lube oil, which meets at least one of the following quality and viscosity classifications. 5.1. Oil quality according to
API - classification ACEA (CCMC) - classification
: CF, CF-4, CG-4, CH-4, CI-4, : E2 (D4), E3 (D5), E4, E5,
5.2. Oil viscosity according to SAE - classification ISO - classification
: 10W : VG 32
6. Grease 6.1. General lubrication points and track tensioner The grease must meet specification KP 2 k - consistency 2 according to NL GI - class and DIN 51818 and DIN 51825 or EP 2 according to NF-T-60 132 . The grease must also be lithium based, with a VKA value of at least 2300 N according to DIN 51350 or ASTM D 2596. 6.2. Long term grease / grease to protect against corrosion For the lifetime lubrication of bearing points of lift cylinder suspensions and to protect against corrosion at the initial installation of dry bearing points, to protect exposed piston rods, to prevent rust formation, etc., a special calcic, acid free grease should be used. We recommend LIEBHERR's special paste CTK - Id. No. 8613 313 01 For general conservation - see section 19, Conservation guidelines - other acid free anticorrosion grease may be used. 7. Miscellaneous Always observe all guidelines issued in the Operation and Maintenance manuals, repair manuals and on drawings. 7.1. Rubber seals on doors and covers Use silicon spray or Talcum powder. 7.2. Hydraulic cylinder installation Lubricant for threads of pistons, piston nuts and piston rod bearings Liebherr High performance lubricant Id. No. 8300 004 Special protection against corrosion for installation of sealing elements Liebherr Special anticorrosion grease Id. No. 8300 005
