heater levers replacement

[jeffc280sl]

i like your ingenious tools.  its still a pain in the a.. job.  i'm sure you're happy its almost finished

Next step.…  refitting he heater levers….. first aim of that discussion !

[yves]

I forgot a important point about fitting the counter:
When you put back the counter in it's right position you have to screw the knurled bolt at it's rear side to fix it on the dash panel . But you can't insert your hand….! you have only some room to slide one finger and you must hold the bolt , put it at the end of the counter screw and turn it clocwise….!
To do that you must take the knob with the "groove" face toward the counter. Doing that the knob stay on the screw even not aligned exactly, but yoy can screw it slowly and cautiously avoiding falling down in the dash…

Yves,

Just want to say that your detail descriptions and input are very much appreciated!  Your annotated photos are great and wanted to thank you for taking the time.

Best,

[mbzse]

.../...But i have not the technical manual to follow the process  . The BBB is not the good book for !

The dis-assembly of the W113 dash is well explained in section 83-2 in the 1959 edition of the BBB.

See it in this posting:

He he, well...  The system operated by Mercedes (Daimler-Benz) was that the Workshop manual (BBB) binders were given out to the authorised M-B workshops only (not available to the public, like today). The literature was aimed at trained authorised workshop technicians.
There were then updates distributed from M-B, several each year. Pages were replaced in the binders at the dealerships. There were also Technical Service Bulletins (TSB's) issued that informed about changes and gave tech tips.
A fully updated Workshop manual (BBB -68) was issued in 1968 (with the introduction of the "New generation" Compact series /8 cars)

Example page from 59 manual attached

So if i am not misunderstanding, i'll need  the 68 BBB  (complete)  has it been written in english ?  ( or i have a dream... in French !)

Yes, that is so. Available from M-B Classic, see Web:

I would suggest also to get yourself the "book of Tables" or "technical data book" as the web site has named it; most useful.
See our Tech Manual: https://www.sl113.org/wiki/Documents/TechnicalData

 I am not sure about the color of each heater lever,  the top left must be blue,  the top right is blue on my car but i think it is wrong . Anyay i have two red lever, i think they must be the two bottom  and remain one " orange"  one which must be the right top one....
Am i correct ?





I can reuse  two red , one blue and one orange.... no more choice  !

[mrfatboy]

Blue - upper left
Smoke/gray  - upper right
Red - lower left
Red - lower right

[yves]

Thank's fatboy   
Ready to be fitted back in to the dash

Is that a new orange lever you have in the upper right?   The original color is gray but after market are orange.

If so, I think you have to grind down the "bosses" so the levers can fully move.

See this thread:

Yes, if you have a dash speaker, you will need to grind down one of the bosses. Look at your old grey lever to see which one to grind. If you leave it long it will hit the speaker magnet when the grey lever is turned.

    i have read your last post a little too late, the levers were in the dash , fortunately i have not yet fitted them back completely

Stay in that good mood. Ability and skill is important but attitude and patience will always see you through to the end. Good job young man!

young man , young man , humm... !

I coud'nt go to bed before modify the lever... so :
grinding the plastic:



But screwing many times in that old plastic made a hole instead of a thread..... By chance after reading some post here i have now some Bondic  on the bench...



After 3 tests it's fine but you need to use some sand paper on the surface before applying Bondic

[doitwright]

Nicely write up of the procedure. I saw a smoke gray lever on eBay recently and another listing where the seller was offering the 4 levers without the rubber components. When I did mine, I removed the tiny rivets and swapped the rubber from the new orange lever and installed it on the old smoke gray.

[ja17]

Yes, I have been re-mounting new rubber on the old acrylic plastic for years. In this way the colors stay original.

Here is the post by Tyler describing how he did it when he did mine.

I make some progress : i have fitted back the levers in the dash…. i had some issue with the tension on the cable rods which prevent to adjust the levers against the dash panel .


I have adjusted after some trys the clips which hold the cables in the bulkhead





Then the levers could be in contact with the dash panel without tension. The great challenge was to put the left nut behind the left  chrome part….
I don't understand why the bolt is so close to the levers..... I succeded with the end of my right index under the levers and the left one above through the speaker aperture....     The two other screws were a children game



Before fitting the chrome, i have clened them on a "wood bench " with hole , so i could press and brush without any danger for the rear screw and the thin metal middle blade




I have may be an odd question about fixing the dash board: It can be lifted on the left, but i have not taken out any bolt or screw ?? have i broken something ? i have not found a schema on the BBB about this dash board. A picture or schema will be appreciated...!

[mrfatboy]

If I remember correctly there should be a metal tab on the dash (centered below speaker grill) with a speed nut clipped to it.   There should be a screw hole on the underside of the dash panel centered at the speaker.  See pic. Another one above glove compartment.

Also a couple of screws on the back side close to the windshield and a hidden one under the covering on far right.

You know what……!  i am very happy it's Christmas and i have some nice gifts and the best one  on the photo below:




Thank's everyone who gave me good advices for the Job….

[jeffc280sl]
