The Service Manual for the Valmet tractors is intended to be a practical reference source to be used in workshop. The repair instructions in the manual are based on methods which have been worked out in practice during normal workshop conditions and which are based on the use of special tools from the manufacturer when stated in the instructions. The manual also contains descriptions of the design and function of the components.
Additions and amendments of the service manual
New and updated pages will be continually added to the service manual. The new pages should be inserted as indicated by the code: the first digit (also the first digit on the index leaf) indicated the group:
- the two first digits indicate the component or sub group
- the third digit indicates the document group for the respective components
- the page number indicates the definite position of the page within the service manual
If there are two pages with the same code and page number the page with the later date in the date box (and the old date in the crossed over box) is valid (or the current page).
Sealing compound and glue
If sealing compounds or glue are required for the repair work, the instructions will specify a sealing compound or glue which is readily available through specialist dealers. Some seals should be greased before fitting and the space between the lips of the seal should be filled with universal grease. If the seal is to be pushed over splines or sharp edges the seal should be protected with for example a thin plastic foil.
Tightening torques and setting values
All necessary tightening torques and setting values for each repair operation are given at the beginning of each repair section under the heading Technical Data. The most important values can also be found in the repair instructions. Table 1 later gives the tightening torques in order of dimension, quality and surface treatment. The values given in the table should be used if the tightening torque is not given in the repair instructions.

Unless otherwise specified, all removals should be accomplished using adjustable lifting equipment. All supporting slings must be parallel to each other and as near vertical as possible in relation to the object being lifted. However, where slings are of a far greater capacity than the weight of the load to be fitted, a triangular lifting arrangement may be used.
Valtra Valmet 8050 Service Manual
To ensure long life of a machine, it is important to keep dirt and foreign material out of its vital working components. Precautions must be taken to safeguard against this. Enclosed compartments, seals and filters have been provided to keep the supply of air, fuel and lubricant clean. These protective devices must not be removed.
Whenever hydraulic, fuel, lubricating oil or lines are disconnected, clean the point of disconnection and the surrounding area. As soon as a line has been disconnected, cap, plug or tape the line or opening to prevent the ingress of foreign material.
The same cleaning and covering precautions should be taken when access covers or inspection plates are removed. Clean and inspect all parts. Make sure that all passages and holes are clear. Cover all parts to keep them clean. Make sure parts are clean when they are reassembled. Leave new parts in their wrapping until they are actually needed for reassembly
Assembly
When reassembling a machine, complete each step in sequence. never partially assemble one part then start to assemble another. Make all recommended adjustments. Always check the job on completion to ensure that nothing has been overlooked. Recheck the various adjustments before putting the machine back into service.
Maintenance Valmet 6000, 8750
Correct maintenance at the right time is a basic condition for reliable operation of the tractor. Maintenance costs are small compared with any repair costs resulting from lack of maintenance. The most important measures are those which you carry out yourself and which include lubrication and various checks and adjustments. The service intervals shown apply for normal operating conditions but in more severe conditions servicing should be carried out more frequently.
