A few things
depending, you might be in/out in a hour or maybe five. 2x4 ,4x4 ,sawzall, files, hammers, ,punches, sand cloth , rust bust , autoball joint forkS, black pipe T - able to slide over the shaft, blk pipe nipples - longer than shaft to bearing, rags , BIG screwdrivers, pully puller's, pipe wrenches, grease gun, oiler ,regular tool box w/ allen wrench's both metric and regular, etc.0 -
bearings
ball bearing and set collar start by checking new parts make sure shaft is straight and there are keyways or flat sots in shaft. Sand and put rust dissolver on shaft by bearings, cut shaft and remove old wheels, install new wheels , slide shaft through wheels dont forget set collars which I like on inside of bearings , you can move shaft back and forth to install bearings, bearings are removed and instlled in bracket by turning 90 degrees, tighten blower wheels on shaft, reinstall blower pulleyThere was an error rendering this rich post.

CV joint
Some of the large carriers I've done have a CV joint between two shafts. Your idea of just replacing the whole thing (shaft, bearings, blower wheels, sheave, is definitley the way to go. You wont need alot of that other stuff seeing your going to toss all but the basket housings. Plan on a day doing it. Some of the carrier shafts go large in the middle but are hollow. Take off the top and take the baskets and all out in one piece, and work on the ground with your Saw-Zall and screw gun. On the new shaft , the cosmoline can be removed with WD-40 and some rags. Have new keys for the shaft also. a good staight edge to align the pulley and sheave. Amp the motor when done to make sure your under the nameplate amp draw on the motor, If not, adjust (open/close) the sheave till you are. Use Never Seize on the shaft, especially if your the one to service this equipment in the future.0
