I have a case 446 lawn tractor that i just replaced a bearing on...the main drive pulley. After assembling new bearing and keying properly, the parts still move down the shaft. HELP! I'm thinking i did something wrong
with this assembly and have tried several attempts to make it right.

Anyone have an idea to try? Or is there a pulley diagram available?

Thanks in advance for any help.:confused:

Thanks Brad for your encouragement. I am frustrated since i have worked on pulley's, shafts, bearings before...just don't know what i have done wrong to cause this assembly to slip!! I am sure there must be a diagram of how the entirety is assembled. Some of the parts i refer to are: 2 bearings brand new, 1 snap ring, 6 flat washers, the shaft, the sleeve, and the case. Some of these are exact, one-way fits..which adds to my confusion. I wish i had paid closer attention while disassembling in the first place.
