You may need a puller...............or a friend that has one...........Good to see you back at it
Its best to CLEAN, SOAK, CLEAN, SOAK, and CLEAN again. Soda blasting after a good degreasing is quick. Bead-blast for a nice finish..........or paint any color you want. Whatever you do...........DO NOT USE SAND OR GLASS-BEAD. Be sure to clean every corner or pocket, including the crank, before reassembly.
