    Build sheet

    Build sheet or rather a strip of paper from under the Jack rubber pad. survived from build date November 1980 .. a 1981 year model 107. A search of the internet and I'm none the wiser on how to read it. ??????????????????????????????????????

    heater decides not to switch off

    Ah the mysteries of Mercedes vacuum system ! Drivers side heat slide control does not apply vacuum to the heat valve. Passenger side works ok, switching off the heat. Heater switched on yesterday , but then would not switch off. All the vacuum connectors behind the panel are good. I can't see...

    K Jetronic idle 107 280 S.L.

    Not quite so simple as it is made out to be. At times the idle speed changed both cold and hot. Not a lot, but it should not be so. The Air flap opened and closed ok .. but the was a build up of krud around it, and looking down inside at the Butterfly , it had a build up of carbon like krud...

    Smoke

    Wot ...no Posts today ! So a modern one.. 2010 C Class 1.8 Turbo. Now and then , on cold start up, there is a cloud of Blue smoke. Then it clears in a couple of seconds. 99.9% of the time the exhaust is clear ,never needs oil top up between changes . Could it have anything to do with the...

    mufflers

    Called Silencers in the UK. Are just that, designed to cut down noise. How much performance is lost by this ? A lot of after market Mufflers make a lot of noise and not much else. I wonder how much comprise is a Mercedes system, i.e., before Catalytic Converters. ???????????? I remember a...

    Trans Oil

    Pads you recomended and supplied work very well in our 2010 C Class Helmet. No Black Dust etc. What oil should I use in the 5 speed Auto ? Now 40000 Ks It has been quirky all it's life, and has had Soft Ware re loaded a couple of time by the Dealer. Now at times only, it is starting to...

    Brake Pads

    Our 2010 C Class will need new Pads now 40K (mostly Suburban driving.) Dust Free Pads seem to have some minuses. On the net. Wet freeway performance Repco Pads ? Stoping power from Higher speeds deteriorates ? Maybe Helmet has the answer ? Thanks Sean

    Tesla

    I talked to a very satisfied Tesla Owner on Saturday...... close to 500ks on a Charge driving gently around the Suburbs. Has anyone driven, say interstate via the New England Highway or up through Broke to Singleton to see how it handles rather challenging Roads. I always found that hustling...

    Fuel consumption

    An interesting experiment from here to Newcastle and back, fiddling with the ignition Timing. The Air Con system has a retard device fitted to the Distributor which operates at all times with the Air off and is disabled when the Air is operating. That is , the timing is advanced about 5 degrees...

    Garage clean out

    Been getting rid of the last remnants of my Vintage Motor cycling Days and I had another bright idea ( I hope ). Most of us have bits and pieces surplus to requirements for our Mercs sitting round gathering dust. Perhaps we could set up a table at the Christmas in July Gathering to dispose of...

    water on Brakes

    A few weeks ago in a very very heavy downpour with the Road flooding my 107 S L lost a lot of braking power and the Pedal became very soft. As the brakes dried out everything was back to normal i.e., excellent stopping Power. I never experienced this on any other car ever ??? Drum brakes, yes...

    Ign Timing

    I cannot find the correct Ign. timing for an early or late 6.9 anywhere on the net. What should it be ? anyone ? With Ant's Cars, I now believe that the early Car is to far advanced at 30% max. Mechanical , no vacuum. It pings badly. And " 20" draw on a Vacuum gauge at idle The...

    Over heating

    I wonder Styria if your expertise on Rovers includes the 75's with the V6 engine ( also used by Kia ) ? A friend has about 6 old cars including the Rover . ( None of them are without major issues ) He has a veneer of mechanical knowledge which isn't very thick. Having said that , I try to...

    speedo slow

    An interesting old post from Styria on inaccurate speedos. My 280 SL is 11% slow on the odometer. I have fitted a higher ratio Diff but the speedo was also too slow with the original diff. Now I know that diff Ratios and speedo heads are matched. The speed reading was easy to alter , just move...

    security

    Not quite a Topklasse topic but perhaps useful none the less. Bank online security from the horses mouth. Our online CBA Banking was corrupted today , thankfully no harm done. Bank security ran me through a procedure to sort it. They advised that I must always log on via "Netbank.com.au " in...

    For budding Automatic Trans mechanics

    Goggle Sonnax Zip Kits . Repair Kits for worn Valve Bodies.... Valve bodies are wearing out as a result of the modern solenoid control of the Duty Cycle of the sliding valves. In and out like a fiddlers elbow as we drive along. Plus there is a range of internal parts for Mercedes...

    dash covering 107 SL

    If the seats are leather ....is the door trim and dash cover also Leather. ?? Or a clever synthetic , which Mercedes are very good at. Either way I guess Leather treatment can't do any harm ????????

    A dog with a Bone

    I should learn to leave well enough alone......... But.... I have established that it is possible to vary the Heat valve by modulating the vacuum, I used a vacuum pump. I know that the Flap is working mechanically . I can hear it open and close . But is it modulating the air flow...

    heater water temp.

    The vacuum water temp valve is either open or closed.... Lots of enquiries ( no result ) to see if anyone has come up with a modification to allow a modulation of the hot water flow to the Heater . i.e., to reduce the flow and control the temperature of the Cabin. .. Been in the to hard...
