whats the deal with the code?
will it only fit if the code matches?

9800 is fot the wagon & 4200 is for the sadan. I will fit but the speedometer may be of. Look at replacing the gear its easier than you think. Look at the link hear on the board. I found instruction on replacing the gear. I had alwasys look in ebay for one with near the same miles. Call Odometer Gear LTD (757) 593-3478.

yeah i replaced the gear and upon plugging everything back together i plugged the tachometer wire in a place it shouldnt have gone and it fried my speedometer

the gauge im looking at only goes up too 85mph where the one in my car goes to 120mph.
Now are you saying that the speedometer wont read accurate if i dont use the same one?

That speedo your looking at on ebay is from a ealier model TURBO that is cable driven.

As B.C. states you need a speedo from the Kxxxxx series, that is electronic.

Sorry I can't help with that correct number.

Good luck,

I would want a speedometer that is like my original 120 MPH but I drive faster than 85 most of the time. The difference is more than like in the tire size. 91 back to 86 should be okay but check the small numbers 9800 or 4200. I would want that to match. 92 & 93 may also be different. I think Antilock brakes were offered around then.

Must have a number beginning with a "K", not an "R".

Both my 1986 and 1988 244s have a K10042. The wagon has a different number following the "K". This unit will run with the electric speedo and non-ABS.

The earlier cable-driven models have the number R 0.xxx, and models with ABS (with thanks to Sven's Maintainer) have yet another code set.

The wagon had a different stock tire size, making the revolutions per mile different thus the different speedo and number.

Good Luck,

Bob

well im looking for an instrument cluster on ebay for an 87 240 wagon
and they have different codes one in particular is r0980
This cluster is from a turbo and mine is not. It looks the same except it has a tach and not a clock.
will it work?

I think the number you're seeing is the one on the front of the speedo.

Cars before anti-lock brakes have numbers approx
- wagons: 9800x
- sedans:1002xx
There's one # for sedans and one for wagons - I just never remember it precisely.

Cars with anti-lock brakes have a different pulse setup to support the brake system, the speedo # is different accordingly.

Cars with standard tranny might be different also - I'm not sure.

The number is basically pulses per kilometer. The wagon and sedan have matching drivetrains - no difference there. But the sedans have larger tires and so the driveshaft revs per km is different.

Never heard of an '87 turbo. Maybe sold outside the USA? Or more likely the donor car had a tach but no turbo.

The other thing to watch for is the variations that began in '89 (I believe) with the auto-clocking of a reminder to get your oil changed. Every 5000 mi. (I believe) it trips the "Service Engine" light. As the years went on there were various buttons and levers to reset the stupid light. One from the same year as your car should be OK. I'm not sure if other years will be OK or not.
