Seat Recliner Mechanism Disassembly

[nthomas1]

Has anybody dismantled a front seat recliner assembly?  I need to disassemble at least one of mine as the chrome is in very poor condition - flaking away in places -  and I want to have the outer plate re-chromed.  I've removed the small screw that holds the two main plates together and am now faced, as expected, with what is probably a quite strong spring.  I'm interested in any tips on next steps - in addition to wearing safety glasses!  I know I'll have to unhook the spring from the retaining lip at right in the photo below.

Im in agreement with Tim, the ones on my 2c Berlina are painted, yes I could get them repainted but as I use my 2c I see no need for the paint to be pristine, up to Autoglym Show Standard, rather than reflect her age and usage.
Besides anything else I wouldn't want to be messing around with a spring that size

Patina I can live with.  This is the one I'm worried about.

I'm with you Norman. I will watch with interest as I will need to do similar ones on the Flaminia.

Might be easier to replace that repair/replate?

Definitely easier Guy, but not really affordable.  If I'm not careful I could easily spend more on the rebuild of my S2 than the cost of a good HF!   Having blown my budget on welding and anticipating blowing my budget on paint, I want to restore as much of the componentry as I can with out replacing.  I'm hoping someone can advise me of the secret to removing these springs.

Hi Norm
Assuming you have or access to, a vice, clamp it TIGHTLY and wrap some locking wire around the outer end of the spring and the other end of the wire around the stem of a strong screwdriver, and pull it away from the anchor point and release it by prising it upwards at the same time. Count the number of turns beforehand. Make sure the wire is strong enough and BE CAREFUL! That`s the method I used to dismantle a similar mechanism on a Mercedes. Be aware it is tricky!

I had a look at doing this work when restoring both my 1600HF and Sport. From memory undoing the spring is the easy bit (in inverted commas). I think the whole assembly is riveted together and I concluded it would be easier to find a better pair, which I did. You may find a chromer who can rechrome the outer face as a complete assembly??

Is it possible to remove whatever stops it unwinding?   Then "just" unwind it, and reassembly "just" the reverse.

Against that idea (as well as loosing the stop...) is that I expect the spring would expand and bind...

From the replies so far these seem difficult to take to pieces ...  but because plating involves immersing the whole piece in solution then taking everything to pieces would seem inevitable so the spring etc. aren't affected.
However have you considered a paint option? Whilst you could do a DIY option with an aerosol you may find a local paint shop that uses something like HydroChrome (see https://www.youtube.com/watch?v=4TDtUHo5cSE for an example). This would give you a good finish but as a more controllable painting process you can mask off things you want untouched and leave the pieces assembled. As quite small pieces I can't believe you'd be quoted a lot which is useful when you're trying to keep costs under control. [Painting may also give you more options around how to tackle those hidden rusty areas as no plating company is going to touch the parts until they're back to pristine bare metal].
Just an idea...

From my experience plating shops cannot cope with painted items but rust is dealt by them with in one of the initial processes followed by polishing the bare metal before the actual tri metal plating process and final polishing.

Some great input from you all.  Much food for thought.

As you know, from the start I’ve been concerned about the difficulty of removing the spring, and then whether it would be possible to refit it afterwards.  I was thinking along the lines of something like John described for removing the spring, but not sure how to then replace it.  However, Tim makes a good point about parts being riveted together.  It would be frustrating to get the spring off only to then find that the disassembly process is stalled because of the use of rivets.  I’ll take a closer look at the assemblies when I get back to the UK at the end of the week.

The alternative is paint.  The process that Scott provided the link to looks impressive.  I has heard of places that provide this service in the USA but when I looked around in the UK a while back I couldn’t find anybody.  It would be interesting to know how hard wearing the finish is.

When I had one of my wheels blasted and powder coated, the company I used had a very high-shine silver finish which, whilst not chrome, would probably look pretty good.  However, i think it was a powder coating, which probably needs the part to be disassembled to allow the prep stages to be performed.

Another option would be to just use a diy high-shine silver paint and accept that the assemblies will not have a chrome appearance.  The big issue with any paint treatment will be how to prep. The advantage of disassembly is that it would allow the part to be stripped in the appropriate chemical bath.  If I were to pursue a painting approach on the still-assembled part I’d have to figure out how to prep it; maybe grind off as much of the pitted and flaking chrome as possible, then apply some sort of “difficult-surface” primer?

If you go down the paint route have you thought about a different finish? I was thinking something like a crackle black finish which would look quite smart and period. The problem with a lot of silver paints is they tend to be quite soft. I know black crackle wouldn't be original but neither is silver paint so from your point of view I wouldn't be too worried about it.

That's an interesting idea Stanley.  I had wondered about black but hadn't thought about crackle finish.  More grist for the mill.
