If you look at the exploded view in the manual of the Richmond that I posted earlier you''ll find a service parts list. I think item number 6 is your idler thrust washer and the table below it identifies their part number as T1088A, which Summit (and I'm sure other places) has in stock for $2.99. https://www.summitracing.com/parts/rmg-t1088a
