Body, interior, paint, chrome, and cosmetic items / Original padding/insulation under floor mats?
« Last post by sl113newguy on Today at 16:21:58 »Somewhat recently purchased a 68 280SL, and still learning about the car.
Recently I found that moths (!) were starting to appear, and lo and behold found them enjoy the padding/insulation that is under the floor mats.
I hadn't looked at this before, and am curious:
1. If under-floor-mat padding was original to these cars, or an owner would have added it later?
2. Regardless, I have removed the padding - it is partially disintegrated - but figure I should hang on to them after killing off the offending months (don't ask how my wife feels about the padding being in the freezer this week) as I want to keep everything that was original to the car with the car. Anyway, I was wondering if it was original, if there is "new" padding that owners use as replacement?
Thanks everyone!

Electrical and Instruments / Re: Horn Frequency Tuning
« Last post by Pawel66 on Today at 16:14:21 »Having fixed some issues that I have come across with the two horns from my Ponton:
1. Broken off insulator plate covering the points lever - cut one from a teflon sheet I had at hand
2. Seized threaded bushing in the collar - the one that is use to tune frequency - a famous mixture of 50/50 ATF and acetone and heating made it move
I progressed with attempt to tune the frequency, where I failed.
Too little adjustment range - when adjustments started going the right direction, I was coming to the point when horns went dead. Could not compensate with the other screw. I landed ca 30Hz below targets on both horns.
I may come back to it, I lost patience for now.
Many thanks to Michael for his help.

Pagoda Spotting / Re: Palm Royale show on Apple TV streaming.
« Last post by Rothko on Today at 15:14:17 »The show hasn't been a big success here (Palm Beach). Other than showing the Bath & Tennis Club and Mar-a-Lago, there wasn't much of actual Palm Beach in the show. I fell asleep watching the first episode and kinda gave up.

Drive train, fuel, suspension, steering & brakes / Re: burnt head gasket
« Last post by elode on Today at 14:23:12 »good technique. I purchased a co2 kit to test the coolant. Well, my test tells me that I don't have a cylinder head gasket to do!!!!
So I think that if it smokes white especially when starting it is humidity in the exhaust and that the mayonnaise seems to be just that too. (I'm in France and the humidity is high, especially at the moment). We're going to drive a bit and check the rocker arm adjustment. For the kit we keep our fingers crossed that it is reliable. I did it 3 times and did the test by blowing into the tube.a big thank you because I almost dismantled everything probably for nothing.

Drive train, fuel, suspension, steering & brakes / Re: Gas (petrol) cap gasket woes...
« Last post by VikDasor on Today at 12:05:19 »I have other issues going on with my original gas cap at the moment as all of sudden it does not want to thread on to the fuel tank so I am currently using my (spare) R107 gas cap at present which infact fits really well but does not look the part.
So not sure what's going on there.

Research & Development / Re: Manual to automatic using W123 automatic gear box
« Last post by lpeterssen on Today at 11:03:15 »Dear Chuen
I think that the mechanic that told you that, did not consider one electrical control issue which is important on the pagodas. That is the fact that automatic transmissions for mechanical fuel injected cars, provided some signals to the fuel injection system to increase iddle speed if the engine was about to quit. (stahl).
There is a connection strip terminal with 4 wires on the automatic transmissions, designed to work with Mercedes mechanical fuel injected cars control logic. That connection block has the following signals, which for sure were not present on a w123 since the control approach was absolutely different:
1. Iddle switch positive signal. Active whenever throttle butterfly at intake manifold is clossed
2. Low transmission oil pressure, trigger signal for the iddle increase selenoid (negative signal)
3. Kickdown signal (for sure this one should be present on a w123)
4. Ground
I work a lot on wiring harnesses, and love also to produce practical solutions for classical Mercedes Benz owners.
I have been asked once by a customer to fabricate a wiring harness to convert his Manual transmission w113 to automatic as per original design.
Since that request, I have made that product standard on my listing on www.wiredoktor.com web page.
See here the link to that:

Electrical and Instruments / Re: I have two electrical wires that looks like goes to the fuse box.
« Last post by lpeterssen on Today at 10:24:53 »Dear Mr. henderson
BobH is right. Those wires go to your transmission 3 port connector. You are connecting for sure the emissions control harness I built for you…..
Your main harness already has a branch going to the automatic transmission. Just route this emissions harness branch in parallel to that one and connect the cable ends on the screwed terminals at the transmission junction/ terminal strip box matching the colours of your existing cables.

Drive train, fuel, suspension, steering & brakes / Re: Rocker Pin Replacement
« Last post by stickandrudderman on Today at 07:46:47 »Do not try to remove the complete assembly; chances that you'll ruin the head are 99%.
Just replace the ball pin.
