Arbor assembly

[MadMike 11]

Is there a trick to getting an Arbor assembly apart? I just picked up a 42" mower deck (Model 575 I believe) and I want to replace all of the bearings in it. It looks like the arbor should just slide apart once the pulley is taken off, needless to say it doesn't seem to want to. Any tips would be appreciated. Thanks, Mike

You may have to file the arbor shaft just below the threads and around the key slot to make it round again. I had to do that to get mine off. You will also have to use a large punch (or press) to tap out the bearing. Mine had to be persuaded a little. There will be a sleeve in between the 2 bearings and you should be able to push it over some to get the punch on the inside of the bearing. Hope this helps, I just rebuilt 3 spindles Randy

Mike, They usually require pressing or driving with a hammer to get them apart. Last summer I rebuilt a 48 inch deck. I took the arbors to a friend who pressed them apart and installed the new bearings. When I got them back, I had to do some shimming with washers to make both the blades and the pulleys line up right. Don't know if he mixed up the parts or not. Anyway, I would caution you to check alignment of blades on bottom and pulleys on top, after new bearings are installed. An uneven mowing job, or a mower that eats belts is not desirable, when it is so easy to check at installation.
