Inspection
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 following5
Gears 2-2, 2-2, 2-7, 2-9, 2-11
Pinion shaft 2-21
Bearings 2-14, 2-18
Seals 2-15
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.

Cushion Control Off
Fig 6. Cushion Control Off
When the cushion switch is illuminated, the cushion solenoid is energised and pilot pressure is fed to port S on the cushion valve. The two inner left and right cushion spools are both pushed into the centre of the outer spool, so that the unrestricted galleries X and the cushion valve spools are open to allow the pilot outputs from the hand controller to pass through the valve unrestricted, to the main control valve. When the dipper hand controller is operated, pilot pressure from the lever to port A, moves the outer spool to the right and pilot pressure is fed to the dipper spool in the control valve, via port C. At the conclusion of the hand controller operation, the returning pilot oil, goes straight back to the lever, with no restriction.
There is no cushioning effect. Hot oil from port R returns to tank via the dipper hand controller, as it does in the warming circuit in the neutral position. K Fig 6. ( T E-117)
