Is your last name McGyver?

Just following up on this. What sleeve do you have? The Yellow 28-tooth driven gear will require the GM 25512340 sleeve. As previously stated, I have one of these sleeves in my spare parts bin which you are welcome to if needed. It is new in the GM box. Let me know.

Holy Mackrel. Using 3.08 gears in the equation, you would need a Yellow 28 tooth driven gear without the reducer adapter that you removed. Is that what you said you had? If so, try using the Yellow driven gear without the reducer adapter and see how the speedometer reads. If you do not have...

Dang. Good catch. I stand corrected. Let me re-work the calculations. For some reason I was thinking the M1009's were running 3.73 gears.

I just looked and I have a new 25512340 sleeve in my spare parts bin which you are welcome to if you want it. All you will need will be the driven gear. If you plan to keep running your same tires & wheels I would get the light green 9774413 driven gear. If you change to larger tires in the...

OK, using the time-tested formula of "# of Drive Gear teeth X axle ratio X (20168 divided by tire diameter) divided by 1001 = # of Driven Gear teeth to use", I determined this: 15 (drive gear teeth) X 3.73 (M1009 rear axle ratio) x 616.99 (20168 divided by your tire diameter of 32.6875) divided...

Gimme a few minutes to run the equation with 33" tire. Are you sure your center of tire circumference is 33", or is that what you think it is? Nothing beats jacking up one front wheel and measuring the COT circumference with a tape measure.

Wow what a coincidence. You were born in Lexington KY and moved to Atlanta? I was born in Atlanta and moved to Paris, KY, just N.E. of Lexington. Actually I was born at Emory University Hospital in Decatur and was raised in Powder Springs in Cobb County. Went to McEachern High School, Class...

OK, here goes - This first photograph shows what the installed assembly should look like when it is clean and without the reducer. You will see that the sleeve has the raised numbers 40, 41, 42, & 43, which indicates that this particular sleeve is for driven gears with those tooth-counts...

It’s not rubbish, it’s science. First, clean the dang area so you can see what the heck you are doing. Then take the blasted reducer off and throw the thing in the trash. Then get a new speedometer cable and a new driven gear and put it all back together. I have both parts here so if you can’t...

Opps, sorry. Here is the TM page for the transmission cooler lines -

Not meaning any disrespect, but sometimes it is helpful to simply refer to the 34P Technical Manual. They are free to download from this site - https://www.steelsoldiers.com/threads/cucv-technical-manuals.220280/

Ditto what Barrman said. The OEM driven gear GM installed in the CUCV NP208 transfer cases was the 41-tooth yellow gear, GM part #1362195. To speed-up the speedometer reading when driving, the tooth count of the driven gear should be reduced; similarly, to slow the speedometer reading when...

I am confident that a new AC Delco speedometer cable can be easily sourced on Ebay - simply type in the GM part number: 25033627. Regarding the driven gear and sleeve at the transfer case, you may find this post helpful: https://www.steelsoldiers.com/threads/calibrating-speedometer.223246/

Did you get this figured out? I'm interested to know what tooth-count drive gear GV installs in their overdrive units.
