If you post up the K or R number on the face of the speedo, we can tell you what they are for.
Here are two I dug out!
K9800
K10042

What does that k number represent? I've always wondered this..
Or, a broken tooth from the original gear jamming the gear assembly. I had one do this until I finally found the stray tooth and removed it
CN: Failed solder joints can be very hard to see, reflowing them is easy.
I have a question about 240 (244 in this case) odometers. Just replaced the gears on my 1989 244 and the odometer is working (i.e., moving and adding "miles"). I thought I was lucky as I've heard of repaired odometers not working, taking a while to wake up, etc, and had a "late awakening" issue myself when I repleced the odometer's gears on my other volvo (1989, 245). But this time, on the 244, I've found that the counters for the total mileage and for the trip mileage are going at different rythms!!! I thought they both moved driven by the back 15 tooth gear wheel and therefore they were supposed to show the same increments !!....well, as an example, for each 5 "miles" increment on the trip counter, I get about 7-8 "miles" increment on the total mileage counter. It's as if one was counting miles and the other km!! Any ideas about how this could be happening?
Thanks!!!

The K-number represents the Kounts per mile. The number of pulses from the sensor at the differential's tone ring per mile traveled. The K9800 just indicates the gauge is for a wagon, and the K10042 from a sedan. It says nothing about the year of the cluster that it fits except that it is 86-91. Those clusters are not all "interchangeable."
First question answered by your second. Third question is no. Just the tire sizes are (or were I should say) less than 3% different.Why are they different? Do wagons use a different sized wheel and tire? Is this to say that the differential from a wagon wouldn't (with accurate mileage) swap over to a sedan?
Boom 3 questions ready go!

<strike>So the tone rings will cause a 3% inaccuracy when interchanged with sedans and wagons? Both my sedan and wagon came to me with 185/70/r14's.</strike>
Just re read that..the tire sizes used to be different? Maybe from factory?
Yes. Do you have an owner's manual?

Yes. The axles are the same, wagon and sedan. The difference in gearing is standard transmission vs automatic transmission. Also, the difference in gearing makes no difference to the speedo because the speedo is reading axle rotation. You can put whatever ratio you want in the rear axle and the speedo will still read correctly.
For the sedan I forsure do. I'll have to look more closely in the wagon. I'm assuming that will tell me the different tire sizes that each car is supposed to use.
