General Information for Work with the Gear
Show cleanliness when repairing the gear and before the gear is opened it must be
carefully cleaned.
Use special tools as stated earlier in this section when removing and fitting the gear.
The seal face between the two parts of the housing is tightened with liquid jointing.
When dismantling the halves of the gearbox from each other, loosen the screws in the
flanged joint first and push/press back the fitting pins.
Press the two halves of the gearbox from each other by means of two rods or the like.
