Service

This section restricted to Duclos Staff users.

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: TBD hrs.

Access cam follower: 1-2 hr
lenses with 95mm front rings are easier to access the cam follower assembly. Front ring and focus scale come off towards the front. The cam follower window is exposed. Further dis-assembly may be necessary for other issues with optics and iris blade assembly. If optics need to drop out, iris ring should be removed as well for an additional hour.
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.
