    5" i believe

    so i have some pulleys like this on my everride.

    what type of bearings are these? are they sealed?

    i have a couple that i think are going bad? it looks like the bearings are punch pressed into the pulley. i have to replace the whole assembly?

    i kind of a cheapO can i just machine off the one side and replace bearing and spot weld it back in place?

    I looked at Stens and Rotary and didn't find one with those specs, That's not a bad price since it has a larger heavy duty bearing.....

    Yep. Works great. Just grind off the rivets , pop the two halves apart, put in a new bearing, and weld or bolt it back together.
    I've done it a couple of times, no big deal.
    If the pulley is welded together, you just grind off one of the flanges holding the bearing in, drill three holes next to the bearing and put in bolts/machine screws, and washers to catch the rim/edge of the bearing. What I did was bed a small lip in the edge of the washer to grip the bearing at the seal area.

    I'm going to mill off the rivets and see what's involved. Ill just bolt it together and spot weld the bolts.

    I used JB Weld to hold the bearing in place. Still working fine as of 9/26/12! (Homeowner use for about 1.5 acres of mowing.) See this link where I got told I'm not wise but it worked for me. And yes, part of the reason is the satisfaction of saving a few dollars! http://www.lawnsite.com/showthread.php?t=308029
