I lost my attempt at an earlier reply, timed out by interruption.
Some of you seem to be over-looking (miss-typing) the difference between the rivet pin being SEALED by the o-rings with-in the Interior diameter of the BUSHING and the ROLLER needing lubricant on both its Interior & Exterior surfaces.
When the Interior of the Roller wears on the Exterior of the Bushing, the roller just rattles around bushing a little more.
When the Outside Diameter of the Rivet Pin wears along with the Inside Diameter of the Bushing, the resulting clearance increases the effective rivet pin center to rivet pin center, commonly referred to as chain 'stretch'.
When a drive chain has TOO little Slack or the 'sealed in' grease is worn-out or the o-rings begin to fail ( and let dirt in) the wear rate of the Rivet Pin and the Interior diameter of the Bushing accelerates dramatically.
This is not how I tried to explain it earlier, when it was still simple. Now its "SNAFU"ed, imo.
Modify at "YOUR OWN RISK"!
