I want to swap the CCU temp. wheel - how do I take the center pin out?
The opening on the side shows the slotted pin head. Do I just grab at it and pull? Would not want to break it so for the first time I will task he question first...
The car is '87 300TD. Any ideas will be appreciated.

bmp anybody? I think I'seen a post from someone who replaced a tape on the wheel of his CCU. Must have taken the wheel out to do that...

As I recall, yes, it just "pops" out.

I had my CCU out and totally disassembled for cleaning. I do not recall the wheel removal being difficult at all except you will want to be careful about a small ball bearing that rides in a channel. It can fall out and roll away before you know it. I would suggest working over a shoe box or something similar to catch the part. The removal must have been straightforward enough that the specific steps do not stand out to me. Mine is from an 84 300D.

The tape on my wheel was crinkled and coming off. I made a new one by duplicating the pattern using Microsoft Excel and printing it in color on some adhesive backed paper, then covering the face with a good quality clear packaging tape. I cut this out, taped it on, and it looks like new. I made it in both F and C. I switched to Farhenheit on mine. I have a few extra copies of the printout and could send one out if you supply a self addressed stamped envelope. PM me.

Thanks for the offer but I am in position to cannibalise an old CCU unit that has a nice wheel. Just could not fugure out how to get that pin.

Today I was finally able to peel out the front cover piece for the temp.wheel and after that like you all said- the pin just pulls out.
Thanks for the help.
