I have a couple of tillers that use tensioner pulleys for engaging the tiller drive. The pulleys have oilite bearings that are a bit dry, especially since I've cleaned them up with some varsol. To relubricate the bearings, I've been soaking one pulley in some SAE 30 compressor oil. It's been completely immersed for a few days now and I'm wondering how it takes to be fully saturated. Is there a better way to maintain these bearings?
