Section 11 MAIN PRINT SHAFT
10.1..... Main Print Shaft - Removal
The main print shaft may be removed with the clutch assembly in
place, but you should remove any numbering heads and loosen the
grub screws in the collars.
Remove the clutch drive belt, the spring and it's retainer bracket
and all the wiring. (See Fig. 9.11). On the friction machine also
remove the ink drive idler pulley from the operator end of the main
shaft by un-screwing it’s shoulder bolt using a 4mm Allen Key.
Remove the circlip and the four bearing retainer plates located on
the inside of the frame plates (both sides), using a 3mm Allen key.
(See Fig. 10.11). The main shaft may now be partly withdrawn to
the clutch side of the machine, allowing the room between the side
frames to be used to remove the operator side bearing using a
suitable hub puller.
Remove the thrust washer, and the numbering head collars, (make
a note of the orientation of their scales to ensure correct re-assy.)
whilst withdrawing the main shaft through the clutch side frame.
