3.5.2 Disconnect the Cardan shaft joint from the tractor's power take off (P.T.O).
3.5.3 Wait for the Gearbox to cool before carrying out any operation. Cooling time depends on
previous use of the Univator before stopping and also on atmospheric conditions.
3.5.4 After having ensured that the gearbox is cooled, rest the Univator in the inclined position
with the use of parking stand. An inclined position is essential to avoid oil spillage from the
gearbox.
3.5.5 Use a “Metric Ring/Flat Spanner” of size 12-13 (for M8 bolt) & “External Circlip Plier Straight
Nose Type” of Size @ 200mm.
3.5.6 Remove the gearbox rear cover & take care that the gasket is not damaged.
3.5.7 Replace the gears mounted in the gearbox with the change gear set, refer the chart 10/11, if
in doubt about the positioning of the gear, and contact the authorized dealer.
3.5.8 Shims are provided in the gearbox to align the faces of the change gears & also to restrict
the axial displacement of the gears. Use the available shims & insert the circlip to achieve
the above condition.
3.5.9 Replace the gasket if damaged. Remount the cover with the gasket, place the bolts with
spring washers & tighten it properly.
3.5.10 Check the oil level with the 'Dipstick', if it is low, fill it with the recommended oil. Refer
Table No. B for the recommended oil.
