Remove the bearing retainer mounting bolts (25) if the unit has the bearing retainer ring. Note: The bearing retainer is a one piece ring for early models. Note: The bearing retainer ring is a one piece ring. The bearing retainer can only be removed after the removal of the exciter rotor. The bearing retainer is located on the inboard side of the end bracket.Note: Two bearing retainer bars are used for later models.
Use the following steps for the units that are equipped with bearing retainer bars.
Remove the top two bearing retainer mounting bolts (25) and loosen the bottom two bearing retainer bolts. Move the retainers enough to allow removal the bearing from the end bracket bore. The retainer bolts also hold the bearing sleeve in place. Do not remove the bearing sleeve.
