AlpinA Gr.2 - Instrument Restoration


Recommended Posts

After a couple of months, finally have all the parts and pieces back from various vendors - Palo Alto Speedometer completely restored (both cosmetically and mechanical) all of the instruments including the Smiths 10k chronometric tacho, I bead blasted the sheet metal surround/housing and re-coated with wrinkle black (as it was before) and then had other bits re-plated.  AlpinA put quite a bit of work into the housing - quite a bit more to it than sheet metal slapped together - no surprise really.  Three thumbs up for Hartmut at Palo Alto Speedo, again so lucky to have a high quality vendor like this within 20 minutes of my house.  All of these gauges are ultra rare and unobtainable now.  The chronometric tacho is essentially like a watch with gears and what not inside and the movement of the tacho is like that of a watch moving in precise increments and has a "tell tale" needle that follows it up.  I took 20 or pics of the wiring dis-assembly - thank god I did - no doubt it would have gone back together wrong.

Are the green dials purposefully the same color - to be able to find specifically at quick glance during a race?

Jason, the green (chartreuse) are from left to right - coolant temp, oil temp, oil pressure - the most important instruments in a race car.  Because of the rear mounted radiator early on, this car had constant problems with overheating / coolant temp.  Makes it real easy for the driver to "see" or pay attention to those instruments.  The other gauges (black bezels) are for fuel pressure and differential oil temp. At one point their was an Ammeter in there but at some point that one was lost - now there is a blank off plate with BmW Roundel.  One thing that I learned during re-assembly, lots of really (really) small screws and washers and nuts - drop one and its a goner.  I put everything back together at a desk inside (my house) working over some bubble wrap (with the small bubbles).  The twenty or so times I dropped a washer or screw and had to shake it out of the back - the bubble wrap catches the item and doesn't let it roll-off (into the nowhere land of the garage floor, wood floor, carpet etc.,).  Glad to be done with this sub-project.

Why doncha replace that missing ammeter with a voltmeter?  Find an old Rabbit GTI or Sirocco; they have the same gauges that are shown in your pictures so will match nicely...

Mike, GREAT call as usual.  I had to check out the net, there are a couple on Ebay.  Close, not exactly the same but the body/guts are all there.  Get rid of the little oil can on the face and the red line in front of the 150 mark and they look identical.  I have a friend restoring a CSL for Monterey this summer and has been dying to find any of these.  This could help solve a couple of problems with the gauges he is looking for.  Great call.  Palo Alto Speedo can re-finish the faces to whatever

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
