    Default D special Jaeger clock

    Inexplicably started working today, for the first time (apart from a previous 20 minute burst at year ago or more) in my three years ownership. Go figure.

    Shhhh...... it might hear you.

    Besides, previously it was always correct. Twice per day.

    Malcolm did it. It is part of his "performing miracles for Australians" program.
    I'm not sure if it was a "job" or a "growth."
    Once upon a time:


    Many R4s (incl. fourgonnette), R5LS, R16TS.


    GS 1015, 1220, sedans and wagons.
    CX 2200, 2400.
    ID 1966, 1969, DS21H, DSpecial, DS23 Pallas.
    C5 2002, 2004 petrol and diesel.
    D Special 1974
    Xantia Activa 1998 (look out Gulargambone)
    GS 5 speed sedan (what a tale)
    1986 2CV6
    CX25GTi 1985 auto
    CX2500 IE Pallas 1985 auto
    DS23EFI 1975 Pallas

    And now:

    C5 2.2 HDI 2005 wagon
    DS23 1973 Pallas

    Just wait Alistair. It will revert to its old habits before long. Mine is at the watchmaker now having the guts removed a replaced with a modern movement. It will look exactly the same but no more second guessing. I can here the purists gasp but from what I read even the repairs don't last long. This will and they won't be able to tell the difference. Why put up with poor execution on the simplest thing

    Take it out.
    Take it apart.
    Put a drop of oil on the jewel and shafts.
    Reinstall upside down.
    Let it run for a week or two.
    Remove and turn right side up.

    It's the least of my concerns. Getting ready to pull the front end apart and send the steering rack off for reconditioning. Plus attend to all the other bits and pieces that will present themselves "while I'm there"... Anybody know of some garage space available over the winter?

    Without access to the Paul Smith Memorial Bottle of whale oil, I used a drop of INOX - an Aussie product. I used the plain variety not the one with lanolin. I did this repair over five years ago and as of last Sunday the clock is still keeping good time.

    The thing that seems to stop them is the two electrolytic capacitors dying. 1.6 pF from memory & polarity is marked on the circuit board.

    Thanks Bruce,

    That could be a handy hint. I am having a battle with my SM Jaeger Clock too. Very happy to work upside down. Seemed OK right way up after clock oil on bottom bearing but stopped when replaced in dash. I can hear it trying to restart after I reconnect the battery some times.

    Maybe they are 1.6 uF microfarad capacitors - bit of an odd size though maybe 1.5 uF would do.

    Cheers, Ken

    I might want to go next size up. They are after all a storage device, intended to smooth power flow through the unit. 1.5 uF should work. Case size is also something to consider. Have you thought about going with a quartz movement?
    The measure of your character isn't what you do when people are watching- it's what you do when they aren't watching.

    1.6 xx is a standard value in the 5% electronic component "preferred value" system. So the component should be available from specialist suppliers.

    Otherwise use a 1.5 or even a 2.2 which in the 10% range and commonly available.

    Just went and had a look at a CX clock that looks to be a dead ringer for the SM internally. It has a BC172B drive transistor, a couple of resistors and two caps that don't look electrolytic in nature besides the driver coil.

    Just went googleing and found this PDF file but there seems to be a picture missing. The circuit diagram looks very similar to the components I have seen in my CX clock but both CX and SM clocks have second hands.

    Cheers, Ken
