Allis B and C differential

Can some one tell me for sure that the differential( ring gear) for the B and C are the same. thanks for your help .

Go to AGCO parts and you can look it up.

the B and C share exactly the same motor, radiator, clutch, transmission, differential, pto and hydraulics... the DIFFERENCE is the final drive cases that bolt to the differential or trans case. The C has each housing about 6 inches wider with different gears and shaft inside.

The B & C do use different ring & pinion sets. The C is geared slightly lower. I would think that you could install a complete ring & pinnion gear set from one into the other though.

Naw, the transmissions are the same the different gearing is in the final drive bull gear and pinion gear. The only difference in the transmissions will be the hand stamped serial numbers. I have two C transmissions and a B transmission in pieces on my shop floor. Be glad to snap pictures of any parts you might want to compare.

thanks guys, I bought a differential on Ebay that came from a B so I guess I will know if it will fit my C when I get it.
according to my parts book they are the same.
