7. ROUTINE MAINTENANCE
7.1 Initial maintenance (after 25 hours running)
Drain all oil from the gearbox, the drain plug is located on the side of the transmission, below the selector lever. A
25.4mm (1.0’’) across flats spanner is required. Refit drain plug. Refill with oil as stated in 4.3.

Check the gearbox oil level on dipstick.
Visually inspect for oil leaks and general condition of the gearbox.
7.3 Six monthly check
Check the remote control operating linkage is accurately adjusted to give maximum travel (stop to stop) in both
directions.
7.4 Annual check
All above checks.
Propeller shaft alignment inspection.
Change gearbox oil and after 500 hours or annually which ever comes first.
7.5 Cone Clutch adjustment
The cone clutch is self-adjusting and therefore needs no adjustment. Should gear selection become difficult it is
advisable to check the installation and operaion of the control cable as discribed in 5.7. if this is correct then the cone
clutch adjustment can be carried out as decribed in 9.7.6. If problems persist after the adjustment it will be necessary to
dissassemble the gearbox to investigate the condition of the cone clutch.
If the cone clutch shows signs of loss of coating, glazing and heat discoloration and the mating gears shows signs of
heavy groove indentations then the cone clutch and the mating gears must be replaced. If only the gears are replaced
then the adjustment of the cone clutch is not required. If the cone clutch is replaced then adjustment needs to be carried
out as described in 9.7.6.
