Removed the Shimano 600 Rear Derailleur (RD-6208) from the Miele Bike & Cleaned

First release the cable (first, cut off the end of the cable with the cap on it) , then just loosen the one large Allen head screw to remove the rear derailleur from the rear dropout/derailleur hanger.

There's a short section of cable housing between the derailleur and the chainstays. 

This little metal adapter allows the cable housing to seat properly in the brazed in cable housing stop on the chainstay. 

 

This is the "back side" of the drop out showing the little derailleur stop that sits against a small protrusion in the drop out. 

The drop out on the Miele bike is marked with the Miele brand and is chrome plated.

"SIS" is Shimano's acronym for "Shimano Index Shifting".  Even though the shift levers are on the down tube, this setup allows for indexed shifting (meaning that it has positive locations for engaging each gear, instead of the rider having to adjust and feel for the correct position...

The freewheels have a lot of damage on the teeth and loose plastic.  I could replace them but for this bike, for now, I'll just clean them up.

Used a sharp knife to trim all the loose plastic from the freewheels.

After trimming all the loose plastic.

Sprayed silicone lubricant all over the derailleurs to allow it to creep into areas where there are moving parts.  I'll let it sit for a day...

Cleaned the small section of cable housing and adapters also...

This end cap is not crimped to the cable housing and comes off.  I'll use it on the Schwinn Paramount, with a new section of cable housing, when I transfer the derailleurs over...
