Thread: Here we go again 86 RRC

Wow, 42k its barely run in!

Nice honest vehicle and having a complete intact interior is 3/4 of any restoration job solved in my opinion.

Panels can be resprayed, but its sitting in a nice original interior that makes for an even more enjoyable classic ride.

Great find ....as jsp says good ones are getting rare now even in 4dr classics .... we'll watch her progress with interest

Cheers

Baggy

A few minor tasks on the list now.

Right hand rear door wont open so im going to have to pull the door card off to reattach the rod or whatever fell off.

Left front shock absorber top rubber is in need of replacement to stop a clunk.

Fuel injection has to work, fortunately it has a Bosch external pump and filter cradle and my replacement Pump arrived today so I'll power syphon the tanks, give em a quick rinse and add some fresh 98 Pulp with the new pump and filter.

Finally I have the drivers window working slowly, so Bailey channel needs cleaning but none of the other windows even twitch.

So id hope to find relays or fuses? Maybe check the earth connections with a jumper lead off the negative terminal straight to the doors.

Any clues with the windows on common culprits?

Cheers,

Tony


Oh and anyone know if you can get a hose kit for the Aux Air valve and vac plumbing? The hoses are brittle.

The switches seem to be the main culprit for the windows. Pull the connectors off and clean them out, they get a lot of fluff and grime in there over the years.

Tony,
I had the same issue with the RH rear window, and it turned out to be the switch itself. Cleaning made no difference.
Hopefully yours fares better.

I find I am spending more time in the RRC than any of the MB's - and the to-do list is growing..

exponentially!

Of the 4 switches the only one I got going was the drivers front which has been replaced in the past as its different to the other 3 so I've ordered a full set online.

The Uro brand switches are not very hardy I have found in the past with Benz's and the feed poles on the switch I pulled apart were very badly pitted and corroded which means they wont feed the rear door switches either which matches my findings when checking the rear door switches for operation as well, left rear would twitch and open slightly off the door switch and its partner in the front bank is a genuine LR switch still part servicable after 30 years but the right rear gets zero volts through the Uro replacement switch in the front bank so we all know where the (+) ive feed comes from lol.

I found it hard to fathom that the entire window circuit relied on feed from the front and that there were no bi metal breakers etc although the way the isolate switch is configured I can see why.
Agricultural but simple.

So the issue lies in the quality of the switch which has a heck of a current draw through it, Pulling the original switch apart and comparing it to the cheaper replacements the build quality is clearly evident so Id say the old practise of cleaning the OE switches was a superior option to replacing them with lesser items.

However I think that after 30 odd years the original items (That remain) are now unservicable although I will do a more indepth investigation/Necropsy on the old switches when I am done getting this old girl roadworthy.

As for the German side of things?
Im down to 4 W116's and a C107 with a W126 SEL on the horizon.
Sent the 124 to the scrappies and when im done stripping 2 of the 116's I'll be down 2 more and of the remaining 2 im keeping one and giving one to a mate to look after (LOL the giving is to work around a minor technicality where he is banned from enjoying life so he is looking after it for me as a favour)

Oh and the bailey channel/rubbers need de filthing/replacing on the Rangie too which wih a bit of light lube should make them quicker along with some love to the motor and arms in the doors.

I do like my glass to be fast.
