Eaton 6309 gearbox
D0 00 584
The Eaton 6309 gearbox has eight synchronised forward gears, one crawler gear
(position C) and one reverse gear. The gearbox has a low speed range (1st to 4th
gear) and a high speed range (5th to 8th gear).
Shifting gears
- To avoid excessive and unnecessary wear of the clutch, always engage the first
gear when driving away. This applies to both a laden and an unladen vehicle.
- Always depress the clutch fully when shifting gears.
- Push the gear lever smoothly when shifting until the gear is engaged.
- Shifting from the low to the high speed range is done with a range-change
switch on the front of the gear lever. With the switch down (position A), the low
range (1st to 4th gear) is engaged and with the switch up (position B), the high
range (5th to 8th gear) is engaged.
