Well I think I did it again. I was looking for a tractor to swap parts out to fix Dads old 850. The last time I bought a 640 thinking the rear end parts would fit. The 640 was easier to fix and I believe the rear end is different from the 850 so I fixed it instead. Its now my main tractor I never fixed a tractor I didn"t love. Anyway the new parts tractor I just got home that I thought was a 800 series, after sanding off all the primer winds up to be a 641-D, with a gas engine, so if anyone knows what the block number B9NN 6015B is, I sure would appreciate if you would let me know. Also If the rear end parts will fit in a 850. Thanks Al

Read the thread below. The "B" has been somewhat of a mystery. It has been used on the diesel engines.

I bought a non-running 841D last week and the block is coded B9NN6015B. It was cast on March 10, 1960.
The rear axle from the 641D will attach to your 850's transmission but everything in that rear axle is smaller including the housing itself. You will probably have a spline problem also- the pinion gear on the 641 axle has a fine spline and the 850 pinion has a coarse spline. You will need to take both couplers, cut them in half and weld two halves together with the correct splines.

Thanks thats what I need to know, Looks like I am going to fix up the 641 and keep looking for a 850. I think I can make a few dollars on it so it will all work out. Bet I check serial numbers the next time.

Thanks Jim but my problem is on the other end. Awhtx Thanks for that advice saved me a bunch, I opened up the hydraulic cover today and found the coupling, looks to be a easy fix to a costly situation.
