440icd bull gear

[jobradovich]

So upon rebuilding the right side final drive on a 440icd. I found the splines on the bull gear are worn and chipped. I’m trying to find a replacement gear. The axle has already been replaced at some point. The part number on the gear is m2364t. It’s a 55 tooth gear. The part number in the parts manual is at15156. I’ve also seen at15155 as a sub for the original number and I’m wondering what the difference is between the at15155 and at15156. The only difference I see is the clearance cuts on the hub of the at15156. The gear from the other final had those cuts but this one does not. I just need to know what gear I need to find to replace this one.

I have gears on hand, not a problem.
