1.
Remove the dust cap (401), the driveshaft retaining bolt
(405) and lock washer (406), the keeper plate (401) and the
retaining ring (411).
2.
For ease of disassembly, it is recommended that the following
tools be made and used as described: (A) round keyed nut,
dimensions in Table 3, (B) removal bolt, dimensions in Table
4.
3.
The round keyed nut (A) is inserted into the free space
between the retaining ring in the gear unit's hollow shaft and
the end of the machine's drive shaft.
4.
The removal bolt (B) is screwed into the nut (A) which
presses a disk (C) against the screw conveyor drive shaft.
The resulting force pushes the gearbox off of the drive shaft.
5.
The driveshaft can now be easily removed from the reducer
by pulling the driveshaft straight out.
