silverbean, If you are needing to replace the front and rear bearings and cups, you will need to unbolt and remove wobble box from header to be disassembled. Then remove top cover halves and unbolt lH and RH flanges and loosen bottom flange bolts, then remove trunnion carrier and crankshaft from support. Remove three bolts that hold front and rear bearing covers with shims and then we remove the outer cage and rollers by cutting cage with side cutters. We then cut inner bearing race with torch.(Make certain that stubshafts are tight in trunnion housing,if they are loose you will need trunnion housing.Bearings should also be tight on stubshafts,if not you will need new stubshaft.) You will need to order new bearings,cups,and dust shields to rebuild. Also check to make sure that trunnion crankshaft bearings do not have any play. When reassembling front and rear bearings we usually drill the bearing caps so they are greaseable like the Series III wobble box.(This makes sure that these bearing get grease since you are only supposed to give these wobble boxes 6 pumps of grease per season.)This also helps in shimming the bearings to obtain .003-.005 preload on front and rear bearings by using a dial indicator to check end play through grease holes. Not that difficult of job,just takes time. If you are in midst of harvest I would suggest taking to dealer or somebody that has worked on this style wobble box as we have seen wobble box fail due to misadjustment of bearings.
