General repair notes
General repair notes GENERAL REPAIR NOTES Cause of damage Recognise the cause of the damage, limit the damage event and secure the machine.
Parts Use original CLAAS Parts and the corresponding special CLAAS tools. In the case of ordering Parts and technical queries, always quote the machine number of the forage harvester, and in the case of the engine, the fitted ancillary units, the maize header, the cutter bar and the maize picker, in addition always quote the specific serial number. This is required since otherwise the wrong Parts could be supplied.
The repair will be quick and correct if the following is observed – Before dismantling or removal the machine parts should be marked to ensure that they are reassembled on the correct side and in balance when being re-fitted. – Roll pins should be always fitted with the slit pointing towards the loaded side. If they are fitted with a 90° offset, they will loosen and fall out or shear off. – Split pins, locking wires, sheet metal locking plates, locking washers and spring rings should always be replaced. – Greasable ball and slide bearings should be used with the prescribed grease. – Chain sprockets and V-belt pullies should be in alignment with each other.
Engine Before working on the engine, always disconnect the battery cable (-).
Transmissions Before dismantling the gearbox, first drain off the oil and then remove the gearbox. Parts which are stuck inside each other should be released with soft metal headed or plastic headed hammers.

Welding work Attention! When carrying out electric welding work on the machine, observe the following points: 1. Disconnect the battery isolation switch! 2. Remove the plug socket to the monitor. 3. Retract the electrical plug-in modules in the central electrical control system. 4. Separate the electrical connection between the engine and the main wiring loom. 5. Always attach the earth terminal for the welder in the immediate vicinity of the welding area.
Three phase AC generator Attention!
– The leads between the regulator and the battery should never be disconnected when the generator is running. – Always check the polarity when connecting the battery since otherwise the diodes will be destroyed. – Fitting work on voltage carrying components may only be carried out if the engine is stopped first and the battery is disconnected. – The normally accepted method of checking whether there is a voltage in a lead, by touching it against mass, must never be performed with three phase AC generators. The semi-conductors will be damaged by doing this. – Disconnect the leads from the three phase AC generator before carrying out any electrical welding work on the forage harvester! – The three phase AC generator is pre-excited via the charge indicator lamp by the battery. Failed light bulbs must therefore be replaced to ensure proper exciting.
