CB/CFE/CFi Service Manual

This Service Manual comprises a spare parts catalogue, a tools catalogue, a repair instruction and a lubrication plan. Determinant for the availability of spare parts is the latest state effective of the spares price list, as may from time to time be established. The basic lens for lists and descriptions is the Planar 2,8/80 CB. The lists and descriptions of the remaining lenses are showing only the differences to the Planar 2,8/80 CB. That means: What you don’t find in the chapter of one lens you will find in the Planar 2,8/80 CB chapter. All repair descriptions deal with disassembly only. Assembling is therefore always carried out in the reverse order. Exceptions are mentioned by the text.

Ordering numbers

The spare parts and tools have 13-digit ordering numbers like ‘102165-0011-180’. There are two exceptions: Some parts have a format like ‘VHAB Code No. 50377’ which you will find in the remark column. Some parts have a format like ‘200 509’, then you will find ‘VHAB Spare Part No.’ in the remark column.

Revisions and dates

To make sure, that your Service Manual is always up to date every page has a Revision counter and a date field. On the next pages you will find the Index of Current Pages, that gives you an overview over the complete Service Manual and informs you what to do in case of changes.

General instructions for repair works

It is recommended to do a receipt inspection before starting repair works. Additional faults could be recognized and the appearance of the faults could give hints to consequential damages. After any repair work a final inspection has to be done.

General instructions for repair works on the barrel

 Only screws with securing adhesive are mentioned in the text. All other screws are screwed in

without securing adhesive.

 The flash contact must be free of lubricant.  The shutter blades and the diaphragm blades and their bearing points must be free of

lubricant.

 Lubrication of shutter parts only according to ”Lubrication Plan”.  It is recommended to change the drive spring 1 (Spare Part No. 102211-1515-000) doing repair

works on the shutter unit. Please see repair instructions ”Exchange of drive spring 1”.

 For works at the printed circuit boards of the CFE lenses: to avoid damages of the IC’s from

electostatic discharge observe the general instructions for ESD prevention.

 Check of shutter speed.  Cock the shutter, actuate stop-down handle, rotate smoothly the diaphragm ring and check at

the same time whether the diaphragm blades open easily, consistently and fully.

 Close the diaphragm; diaphragm blades should move consistently and jerk-free.  Release stop-down handle; diaphragm blades should open fully.  Check flash contact.

 After repair works check dimensions related to lens bayonet flange, planartrueness and

concentricity (Tool No. V-2180).

 Check functions with standard gauge (Tool No. V-2223). See instructions for standard gauge.  Check lens adjustment with collimator.  For maximum optical performance MTF equipment is recommended to use.

The following tools are necessary for dismounting and mounting of lens elements:

Front lens element / Front lens Tool No.

• Unscrew engraved ring 102165-0000-901 (snap ring is snapped in from the rear)

• Unscrew front lens element 102212-8105-901

• Unscrew lens holding ring

• Remove front lens

• Assembly is carried out in the reverse sequence analogously.

Rear lens element / Rear lens Tool No.

• Unscrew rear lens element

• Unscrew lens holding ring 102212-8106-901

• Remove rear lens

• Assembly is carried out in the reverse sequence analogously.
