BMW E9 Instrument Cluster
Pulled from US-spec 4-speed 2800CS
Speedometer in mph
Very good original condition
Bench tested, everything appears to work
$700 plus actual shipping in the continental US.
[ADDENDUM: I fixed the clock. It just needed a bit of lubrication.]
I pulled this instrument cluster out of a US-spec 2800CS I parted out over 35 years ago. It's been sitting in clean dry storage in my basement ever since. It's in very good original condition but could use a cleaning. The wood veneer is in remarkable shape, with just one barely visible hairline crack in the upper right corner. The lenses have no obvious scratches. The chrome rings in front of the lenses have the smallest hint of corrosion. The gauge faces themselves are in excellent shape. It comes with the harness and the trip odometer cable and knob. I bench-tested the cluster with a drill spinning a speedometer cable, 12V and ground supplied to the individual gauges, an RPM signal supplied by my own E9, and the gas and temperature gauges tested by making sure they read zero when the sensor connection is lifted and peg when the sensor terminal is grounded. Everything appears to work, including the clock.
My price is $750 including shipping in the continental US. For comparison, there's one of these clusters on eBay in upstate NY for a Euro car (speedo in km), with the gauges "cleaned up and verified for proper working order" and a gouge in the wood, for $1300 returns not accepted, and two in Germany, also in km, each for $750. This one's in mph, and if it's not what you think it should be, I'll take it back provided you pay return shipping.
TEXT ME IF YOU WANT IT at 617-three-six-five-eight-three-oh-three. I'm much more likely to see it than if you respond in this post. It's also for sale on two E9 Facebook forums.
Payment via Venmo, no-fee PayPal, Zelle, or paper check if necessary.
[Photos follow. After the photos is a detailed discussion of which differential this speedo is calibrated for.]
----------------------------------------------
-----------------
Below is information about what differential the speedo is most likely calibrated for.
My memory is that I pulled the cluster from a US-spec 2800 with a 4-speed ZF gearbox. I remember the ZF box sitting under my mother's front porch for over 35 years, so I don't think I'm wrong about it being a 2800CS and not a 3.0CS.
The numbers on the back of the speedo are "6.69 w1.1 20/134/2." There are two threads on e9coupe about these numbers. In the first (https://e9coupe.com/forum/threads/speedometer-and-differential-ratios.35162/), HB Chris says:
"3.25 Open - CSi
3.25 LSD 25% locking - CSi and CSil
3.45 Open - Euro 3.0CS/CSA
3.45 LSD 25% locking - CSL, Euro 2800CS/CSA and 3.0CS/CSA and US 2800CS/CSA
3.45 LSD 40% locking - Euro 2800CS/CSA and US 2800CS/CSA
3.64 Open - Euro 2.5CS/CSA and US 3.0CS/CSA
3.64 LSD 25% locking - 2.5 CS/CSA
The LSD could be ordered as an option as well.
Speedometers
The speedometer ratios are as follows (numbers stamped on the speedometer are rounded and include a mm/yy build date):
3.25 KPH W= 0.679
3.25 MPH W= 1.078
3.45 KPH W= 0.7125
3.45 MPH W= 1.14
3.64 MPH W = 1.2164"
In the second (https://e9coupe.com/forum/threads/c...ph-to-km-whats-wrong.23254/page-2#post-173860), HB Chris says:
"I'm going to make an educated guess from looking at the parts books:
W=0.679 kmh on CSi and CSL is for the 3.25 differential
W=0.7125 kmh euro CS and CSA is the 3.45
W=1.078 mph euro CS and CSA is the 3.25
W=1.14 mph US/NA CS and CSA is the 3.45
W=1.2164 mph US/NA CS and CSA is the 3.64"
With all that, I believe that "6.69" is a June 1969 manufacture date for the speedo, and that the "W1.1" means it came from a North American-spec 2800CS with a 3.45 differential.
Note that a speedometer shop like North Hollywood can recalibrate it for another differential ratio if necessary.
