ACfan Posted July 2, 2008 Posted July 2, 2008 The spindle bearings on the 48" deep mower deck of my Allis B-112 need to be replaced. I have the spindle shafts removed from each 4 1/2" arbor, but am not sure how the bearings come out from the arbor. There is an internal spacer between the bearings. Should both bearings be pressed out in the same direction? Or, is each bearing resting on a shoulder within the arbor housing, meaning they will have to be pressed out in opposite directions. The internal spacer prevents me from pressing each bearing from its backside. Thanks for the advice!
RayS Posted July 2, 2008 Posted July 2, 2008 Their resting on a shoulder. Try moving the spacer off to the side with a punch or something like that. Then you can drive them out.
ACfan Posted July 2, 2008 Author Posted July 2, 2008 Thanks Ray. Exactly what I needed to know. The spacer must be seized in place. That's why I assumed it was the same diameter as the bearings. Will use some more force to dislodge the spacers to get at the back side of the bearings to push them out. Your help is appreciated!
PhanDad Posted July 2, 2008 Posted July 2, 2008 You may want to check out this post to see what the inside of the arbors look like: http://www.simpletractors.com/club2/topic.asp?ARCHIVE=true&TOPIC_ID=33982&SearchTerms=arbor It's been my experience that the bottom bearing does not always seat against the bottom ridge or single indent. (The arbor assembly instructions say to fully seat the upper bearing and then with the upper bearing held in place, the lower bearing is pressed in until the inner races are in contact with the spacer). I've usually been able to drive the entire bearing/spacer assembly toward the top a little to free up the spacer and get it to move to one side.
