JAFE, that is what i am thinking. the whole idler is only 13 bucks. but still a neat site, and I may come up with other applications where the 6 dollar bearing might save me 50 bucks.
Oldnslo, the suffix of the bearing tells you what you need. the one on my Ranger was a 6203LLU which turns out to be a 40mm OD (the 62 in the bearing number), 17mm ID (the 03), 12mm wide sealed on both sides bearing (the LL, single L is for sealed on one side, I forget what the U was for...). there definitely are several variants of the 6203 bearing.
more than likely to make the job of pressing hte bearing out, I would need a press of some sort to do so, but currently my press would be a 3.5 inch Babco vise utilizing a socket as a pressing ram...
