Service Manual: Disassembly/Re-assembly
Screws: Canon

Full CLA: 16-18hrs.
Enter relevant notes here
clean front optics: 5-6 hrs.
May require a full disassembly to clean all optics, depending on the location of the contamination, especially when disrupting field/centering, which can be a real pain, though the lens can be separated if just accessing focus or zoom optics.
clean all optics: 16-18 hrs.
tracking (no dedicated tracking screws): see notes
Tracking can sometimes be accomplished by loosening mount and sub-mount screws and shifting the the lens around (with a rawhide mallet or your hands) on the projector. Canon says tracking adjustment is located in zoom group which requires full disassembly.
centering: see notes
Rear/wide centering is done by removing mount, sub-mount, circuit board, and loosening rear group screws, then shifting rear group on the vertical collimator. Front/long centering is done by removing the front engraved ring, loosening the front group screws, then shifting the front group while on the projector.
reset field: 3 hrs.
Rear/wide field is adjusted by removing the mount, sub-mount, electronics, and then loosening the back focus assembly screws, then re-installing the sub-mount and mount, going to the projector, and moving the lens around (much like tracking adjustments, though you would need to do this before tracking), then carefully removing the lens from the projector, remove the mount and sub-mount, tighten the back focus assembly, re-installing the sub-mount/mount, and checking it again on the projector to ensure you didn't accidentally shift anything.

Front/long field is adjusted by a combination of shifting two groups. The first is done by removing the front engraved ring, loosening the screws for the second group (through access holes in the front group), then using the eight set screws around the perimeter of the lens near where the front engraved ring attaches. The second is done by removing the rubber focus grip, removing any Nitto tape covering access holes, then rotating the focus ring so that you can access and loosen the four silver socket head screws, then adjust the group by using the eight set screws.
Iris only: 2 hrs.
Focus only: 8-10 hrs.
lens can split. screws located under focus rubber grip. remove 10 black socket heads and black set screws located towards front of lens (not the 4 silver socket heads located towards rear of lens in same location. splitting lens will mess up field (set screws)
Mount conversion: TBD
Lens must go to canon
