Re: Deck Pulley & Bearings Easy Removal
For bigger idlers which are in two halves, riveted together with a bearing in the middle, you can drill out the rivets, replace the bearing and bolt the two halves back together. Way cheaper than replacing the whole idler, and you can do it indefinitely (as the two idler halves don't wear out).
You can do the same thing if they are spot welded together, by drilling the spot welds and then bolting the halves together after replacing the bearing.
