It's difficult to tell without seeing the roller removed for a closer look. Something like our 87-147 might work, but window rollers are tricky to replace since dimensions must be exact. You'll need to remove your old roller and compare to confirm. As far as the removal process goes, besides removing any screws in the channel, the channel likely bends in a way to keep the wheels pinned into it and to prevent them from sliding around. We suggest getting a chisel or slot screw driver and tap it with a hammer open up one side of the channel to slide out the wheel assembly. After installing a new wheel, just re-pin the channel. |
