Millhead T-Key
The millhead has a T-key between the drive shaft and drive pulley. If you raise the
millhead more than usual, this key may come partly or completely out. If it is out only
partially, raise the millhead slightly. Then reach down inside the drive pulley with a
screwdriver and push it back in. Align the keyway in the shaft and lower the millhead into
place.
If the key fallen out, it is probably sitting on top of the column. Raise the millhead
completely off of the machine and reinstall the key into the keyway on the pulley. Then
replace the millhead.
Repositioning the T-key means inserting the shaft into a blind hole. If you put some heavy
grease or Cosmo line on the back of the key, it will stay in place when you insert it. If you
use your finger to put it into place, put a bit of the grease on your finger.
24.3 Lathe / Mill clutch
If the lathe clutch drop into neutral while turning, there will be too much gap between
the jaws of the clutch. You must first determine how much gap there is. A spring-loaded
steel ball in a detent in the jaw clutch holds the clutch in place. Pull on the clutch sleeve
until you feel the ball drop into the detent and scribe a mark on the jaw clutch at the
base of the bearing cap (Figure 24.3). Then pull the clutch sleeve out as far as possible
and scribe another mark at the same place. The distance between these two marks is the
amount of gap between the jaws.
Figure 24.3 Scribe a mark on the jaw clutch at the base of the bearing cap.
