I had to replace a brush shear bolt yesterday but I wasn't able to get the brush shaft bearing off. I'm not sure if there is a trick to getting it to come off or should it just slide off of the shaft? The attached picture shows the bearing I'm referring to. The bearing would slide about an inch towards the end of the shaft but it wouldn't come all of the way off. Any suggestions or tips for me to be able to remove the bearing? Thanks
