Glad you sorted it. I hope it lasts for years. If I correctly understand the arrangement of shaft and bearing, I offer the following to you to consider for future repairs. You would have been far better using a bearing and outer bush. Reason, you have a radial load on this shaft and bearing from the belt. Every single rotation applies the load on the shaft at every different degree of that circle, continually changing. Shim material in this situation can compress or wear and migrate. Had you used a bearing with the correct diameter inner, the shaft would have been solidly located in the inner bearing. The outer of the bearing in the bush has load in one constant direction, and a bush is a formed tube that can not dislodge or migrate. YMMV.
