Known Issues:
1. if optical core is loose in housing or collimation changes (may require tapping lens alternately on the front and rear to see the change while evaluating) most likely the cam follower assembly (2 pieces: brass block and follower) are loose, bent or damaged. Quote replacements initially and remove from estimate if not needed after opening the lens.

Service Manual: (Insert link to manual here)

Full CLA: 6 hrs.
Enter relevant notes here
optics only: 2 hrs
separate + re-cement rear doublet: + 2-3 hrs
iris jams: 1 hr
check that long mount screws are not preventing iris from full rotation.
iris timing is off: 5-8 hrs
if stops are already adjusted, rear optical group needs to be rotated and secured for proper iris “timing” on scale. requires dis-assembly to access optics. can skip C+L of focus cam in most cases.
re-collimate back focus: 1 hr. HOWEVER
if lens is long, then a datum ring of a smaller size is needed and should be quoted as well.
