General General GENERAL Introduction This CLAAS REPAIR MANUAL is to assist in pre- serving the permanent working order and therefore the high value of your CLAAS combine-harvester by careful maintenance and service. Experience gathered by both our service engineers and factory staff has been compiled in this REPAIR MANUAL.
General Introduction to the CLAAS Repair Manual The CLAAS REPAIR MANUAL is divided into main groups and subgroups. The first figure at the bottom of each page refers to the main group whereas the second figure following the point indicates the subgroup; the figure behind the second point indicates the page number.
The meaning of these symbols will be easily recognised and remembered by the user. These This CLAAS REPAIR MANUAL uses some symbols as symbols are to help to quickly recognise recurring defined in the “DIN 30600 Symbol summary” by the service procedures and they also help to communicate German Standardisation Institute.

(accident prevention). CLAAS is in no way liable for any damage or personal injury caused through the use of other than original or approved CLAAS parts, acces- sories and ancillary equipment.
Please pass all safety addition, also modifications and changes may only instructions on to other users, too. be carried out with the consent of CLAAS, as any such actions may have considerable adverse effects on the safety and operational function of the DANGER! machine.
– Therefore, With valve-controlled pressure accumulators – as please take appropriate precautions when for example on the CLAAS Autopilot – first slacken working on the compressor-type air conditioner. the short-circuit bolt before carrying out any repair work at the pressure accumulator.
When removing the gearboxes, first drain the oil and NLGI class 00 (e.g. CLAAS semi-fluid lubricant EP 00) then remove the gearbox. Separate parts which are is applied and that the components are tightened to firmly connected with each other by means of a soft the specified torque in the correct order of assembly.
Prior to installation, apply semi-fluid lubricant of lated adhesive rapidly to the specified tightening NLGI class 00 (e.g. CLAAS semi-fluid lubricant EP 00) torque. When removing these bolts, quickly unscrew to the inside ring and the shaft to make bearing them completely.
Installation: Insert the pre-assembled tube into the well-oiled threaded joint, tighten the union nut up to the point where resistance is felt and then half a turn beyond this point. 1.3.3 188 678.1 - RHB LEXION 480...
