How to CLA Retina II (142)?

<p>Hi,<br /> I just received my Retina II (142), however the RF needs to be calibrated vertical and horizontally. Besides the shutter is slow and weak to fire in slow speed.<br>

Can anyone tell me how to CLA this camera? Thank you.</p>

<p>Removing the complete top cover:<br>

-The rewind wheel is held on by two screws in the stem, there is also a little sheet metal part in there, but I've not figured out what it does exactly, keep an eye on it and reinsert it when reassembling.<br>

-The winding knob can be removed by turning it in the opposite direction of the arrow.<br>

-Remove the screws holding down the top and you can just lift it all up; The shutter-release button should pull right out with the top, just be mindful that you insert it in at the correct angle when reassembling<br>

What ever you do, DO NOT touch the beam-splitter! The gold coating tends to flake off from simply staring at it!<br>

I believe Richard Oleson had a sketch of how the RF mechanism works and which screws to turn to fine tune it on his website.</p>

<p>Good luck. I need to reallign my RF in my model 142 as well.</p>

Thie website - http://rawhiti.tripod.com/ - has lots of info. In addition to running a Retina repair shop Chris' pages have useful stuff for the DIYer.

<p>I did some searching but Richard Oleson and Chris' pages do not include any information about Retina II (type 142). I tried to remove the front element but no success. Only the front element can be taken out. So how to remove the front group elements ?</p>

<p>This pretty much sums up my personal experience in camera repair. Thanks for a chuckle Rick. Not many are brave enough to own up, as a man does..... :)</p>

<p>I have a Retina I (101, I think), that badly needs a general overhaul, I actually bought it for that. Let us know when you get further along. Many of us will be watching and will appreciate any thing you learn.</p>

<p>I removed all screws of the RF unit and put them back . Everything works again by luck. <br /> However I notice it is rather difficult to rewind film after shooting. The connection between the rewind knob and the fork below is loosen.I am trying hard to fix them.</p>

<p>There is a chance I have that sketch for the RF adjustment in the 142 on my HDD at home. But it sounds like you've figured it out yourself. </p>

<p>I'm not sure about the rewind wheel and stem getting loose, perhaps someone tried to force it with the lock engaged.</p>

<p>I got it fixed by pressing down the little metal cover. It helps to enable the V-shaped little metal plate ( below the cover) lock the joins.<br>

CLA a Retina II 142 is not easy, especially the RF. Its design is totally different from the letter version.The vertical adjustment is done by turning 2 little screws on the metal bar, which opposite to the round wheel.</p>
