Sounds like my Belt tensioner pulley bearings are starting to go, has anyone replaced the bearings instead of the entire pulley ? | ||

Just did it last week lol.... The only comparable bearing that I could find was at NAPA..... Part # P62032RSJ.... Gonna keep an eye on em to see how they do and check on em at 1000 mi, then every 500 after that and if they stay solid after 5000 i will feel fairly comfortable. | ||

Just replaced mine 2 days ago. Local bearing supply house is where I found mine. (TIMKEN P203PP Z3 FD50000) I leave the pulley bracket on the bike and just put a wrench in behind the pulley to hold the nut & then use a Torx bit to remove the center bolt and the pulley will drop out. (I've always done this during a tire change and so the belt was loose.) Of course you could remove the pulley & bracket as one if that seems easier. And you could always back the rear axle shaft most of the way to remove the tension from the belt, instead of pulling the wheel completely, which I think would be a lot easier than fighting the pulley under belt tension. There's a little circular retaining clip. (Kind of like a cross between a key-ring and a Slinky) You'll need a couple of smaller flat-blade screwdrivers to work it out, but it's pretty easy. (But can be tricky the first time.) Make note of the locations of the aluminum center buttons as they're different. You can use a pair of pliers to grab & wiggle them out or tap them out once the bearings have been removed. Put the pulley in a vise and pick the clip out. You can then use a couple appropriately sized sockets and the vise to press the bearing out or just use a socket on an extension and drive them out from the back side. I make sure to clean the pulley center bore before reassembly and put a nice coat of anti-seize in there. Use the vise to easily press the first bearing in; then the 2nd until it's flush with the pulley surface. Then use one of the old bearings as a driver and stack it on top for the last squeeze of the vise and then reinstall the circular clip. MAKE SURE YOU NEVER PRESS FROM THE INSIDE OF THE BEARING. Make sure to only press on the outside (OD) diameter of the new bearing, unless you want it to lead an extremely short & unhappy life. Once the bearings are fully installed and the clip is back in place, put a little anti-seize on the aluminum buttons and stick them back into the appropriate side of the pulley bearings and then use the vise again to squeeze them back into place. Re-install the pulley and ride another 40k or so miles. | ||
