Agreed. When you remove the bearing/pulley assy , you simply hold the block with your finger and thread a second 7/16 bolt into the block to hold it in place while you replace the bearing/pulley. I have personally never had to replace a bearing (They use high quality modern sealed bearings instead of the 45 yr old original design) but have had to remove them to make the belt change easier. Takes seconds for one person rather than minutes with two for the stock arrangement.
