Sparky-(Admin) 26,194 #2 Posted 3 hours ago It’s the standard drive belt that all the 300 & 400 series 8 speeds use…WH Part#7473. I don’t know the actual size though. Share this post Link to post Share on other sites

Ed Kennell 46,815 #4 Posted 28 minutes ago This belt works great on my 310-8. I don't know if the 520 requires the 83 1/2 ", but the belts from TSC are returnable for a 100% refund. Share this post Link to post Share on other sites
