Removing the Apron from the MI-1220 XL
Please have the manual at hand when working on the machine and when calling Smithy
Co. for assistance. The apron is removed with the leadscrew still installed in the apron.
This prevents the worm gear inside the apron from falling out off place.
Procedure:
1.
Remove the taper pin from the left end of the lead screw. This is a tapered pin and
must be driven out from the small end.
2.
Remove the 2 screws from the right support of the lead screw and remove the
support.
3.
Slide the tail stock off the machine.
4.
Remove the 2 screws from the fromt support of the crossfeed screw and slide the table
back away from the front support far enough to be able to get the 4 screws holding the
apron on.
5.
Remove the 4 screws that hold the apron to the carriage. The apron will drop down
far enough to allow the apron gears to disengage from the toothed rack on the front of
the machine and let the entire carriage to move freely left and right.
6.
The apron will not drop down far enough to come free from the carriage because of
the two taper pins that would go through the carriage inot the apron.
7.
Loosen the two carriage gib adjustment screws to allow easier removal of the carriage.
With the assistance of a helper, slide the carriage, table and apron assembly off the end
of the machine just enough to be able to remove the apron then put the carriage back
onto the machine.
8.
Tap the two taper pins up and out of the carriage to allow the apron to be reinstalled
without removing the carriage from the machine.
9.
To remove the leadscrew, turn the apron upside down and remove the cover. Pull the
leadscrew from the apron and watch the position of the worm gear so you will know how
to reinstall it properly. There is also a key inside the worm gear. Make sure the key is in
place when reinstalling the gear and screw shaft.
10.
Reverse the above procedure for assembly.
