Installed the Front and Rear Derailleurs to the Schwinn Paramount





Because this frame doesn't have a brazed-on front derailleur hanger, an adapter needs to be used.  I happened to have this adapter already and it's the right size for the seat tube.


Just a single Allen head screw is used to clamp it to the tube.

The rear derailleur is just a simple one bolt installation.

Cleaned the front derailleur some more using steel wool.

Cleaned up pretty good with the steel wool.

Pretty much ready to be installed.

Installed but not fully clamped in position.  The position needs to be adjusted once the chain rings are installed, so the mounting screws are just snugged for now...



I cut a piece of cable housing to about the right length (to allow for the derailleur rotation) and added end caps.  It's ready for the cable to be installed.

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.

At the top of this picture, it shows how the plastic portion of the freewheels are pretty damaged/frayed...

"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...

This cap is crimped to the cable housing and the housing is damaged...

Removed the Shimano 600 Front Derailleur (FD-6207) from the Miele Bike & Cleaned

Loosen the bolt for the cable (the cable was missing the cap at the end and was pretty bent). 

Remove the front derailleur by removing this one bolt.  It's pretty corroded but it came off OK.  This type of front derailleur is mounted to a hanger that's a part of the seat-tube. (some don't have this hanger incorporated into the frame & use a front derailleur mounting clamp that goes around the seat tube and clamps to it).

The cable guide on the right side of this picture is where the front derailleur cable goes through.  The LH cable is for the rear derailleur.
