Operation process   Note The ring seal for the flange between the pair of bevelled gears can only be replaced with the bevelled gears removed. –  Remove the pair of bevelled gears → Chapter

–  Place bevel box on hole marked -4--arrow- in gearbox support -T10108 -. A  -  The nuts M12 x 10 (4 pieces) between the pair of bevelled gears and the bracket for the gearbox. –  Then align the bevel box with the three remaining holes and secure. –  Place oil extraction equipment -SAT 1100- below. –  Let the oil from the pair of bevelled gears drain out.

–  Arrest the output flange for the bevelled gears using the gearbox support -T10108/1 -; Screw in the M10 x 30 -arrow- screws for this purpose. –  Unscrew hexagon bolt for output flange. A  -  36 mm socket for 3/4" drive –  Turn the pair of gears so that the flange inserted looks upwards

–  Remove the output flange from the driver of the pair of bevelled gears. A -  Extractor 3p -KUKKO 45/2-   Note On removing the flange, the inner ring of the roller bearing remain on the flange, and must be removed → Anchor. –  Place thrust plate -40-105- on output flange.

–  Remove the seal -A- for the output flange. –  Clean any residue of locking fluid from thread of shaft bevel gear.

l  Make sure that the shim -2- adjusting the bearing preload of the shaft bevel gear -1- is still fitted. –  Position the inner ring of the roller bearing -3- in the outer ring of the pair of bevelled gears. –  Lightly oil the exterior of the new seal -4- for the flange.

–  Fit new seal in as far as it will go using the pressure tool -T10049-. –  Pack space between sealing lip and dust lip half full with sealing grease -G 052 128 A1 -.

–  Pull on output flange using two arm puller -A-. A  -  Extractor 2p -KUKKO 20/10- –  In doing so, position the extractor gripper under the drive pinion casing. –  Coat threads of new hexagon nut with locking fluid -D 000 600-.

–  Tighten the new hexagonal nut for the flange. Tightening torque → Item A -  36 mm socket for 3/4" drive –  Fit the pair of bevelled gears → Chapter –  Fill the oil for the pair of bevelled gears → Chapter.
