Drive gear box:
When it is necessary to disassemble the drive gear box:
Remove the four screws, which connect the drive gear box to the quill housing. Then
take away the fan cover and the fan from the quill housing. By knocking slightly on
the rotor shaft, the drive gear box can be removed. The gear box casting, consisting of
two halves, can be taken apart by loosening the four screws. All shafts can now be
taken out for further disassembling.
When re-assembling the drive gear box, check that the shift pin fits properly into the
groove of the clutch. When re-placing the drive gear box on the quill housing, it must
be checked that the driving keys in the spindle are in place and that they will fit
properly the corresponding key ways on the gear box output shaft.
Spindle:
The spindle is journalled in the quill by a taper roller bearing at the bottom and by a
radial ball bearing at the top. At the top end of the spindle, there is a nut with which
the play in the taper bearing can be adjusted. This nut can be reached, when the quill is
removed from the machine as follows:
1. Remove the depth stop rod and feed out the complete quill.
2. Hold the quill, so that it doesn't fall out and gets damaged.
3. Let the spring pressure depress by letting the handle slowly return.
4. Adjust the play at the top end of the quill. Make sure it doesn't turn heavily.
5. Re-assemble the quill by turning one of the handles in the feed shaft about two
turns for counter balancing the quill, and put back the quill.
6. Make sure the keys on the spindle coincide with the key ways in the spindle shaft,
and that the teeth of the feed shaft get the grip of the quill feed rack.
7. Let the quill return to the top position, check the position of the feed handles, and
adjust by the feed shaft teeth grip another rack position. Re-assemble the depth stop
rod.
Counter balancing:
The spring housing for counter balancing of the spindle is removed as follow:
Unmount the electric box from the spindle house and put aside (you do not have to
disconnect the cables).
Undo the screw, which keeps the spring housing to the spindle housing.
Let the spring housing turn to release the pressure on the spring. The housing with
included spring can now be removed.
When assembling, press the spring housing into the slot on the shaft.
Make sure that the slot goes against the first bending on the spring. Turn in counter-
clockwise until desired counter balancing is reached and then lock the spindle housing
with the screw.
