Rear chain (108 links)
Rear drive chain, 108 links, listed for 1971 in the rear wheel section of the catalog.
This is the rear drive chain listed under 60-3490, also found in older paperwork as D3490. The parts book calls out 108 links, and it sits in the rear wheel section of the catalog, so it's the chain that runs from the gearbox sprocket back to the rear wheel sprocket, carrying the drive to the ground.

Our catalog record for this one only shows a single appearance, tied to a 1971 listing, so we don't have a broader spread of model years to point to. If you're matching this up to a bike outside that record, give us a call and we'll confirm before you order.
Chain wear shows up as slack that won't tighten up with normal chain adjuster travel, or as uneven links that make the chain hop on the sprockets. Worth checking sprocket wear at the same time you're replacing the chain, since a worn sprocket will chew up a new chain fast.
