Before assembling the gear box make sure that a thorough inspection of all the components is carried out. Remember
that although a failed component may be easy to identify, the cause may be less easy to trace. It is also possible that
a failed component may have caused damage to other areas of the gearbox.

Components that are subject to general wear and tear are
the following:
Gears
Pinion shaft
Bearings
Seals
1 Carefully clean all components using a suitable degreasing agent.
2 Carefully inspect all gears, bearings and shafts for signs of excessive wear or damage. If wear or damage is evident, components must be renewed.
3 In the case of damaged gears, for example a planetary gear, do not proceed to replace the individual gears but the entire assembly.
