I just obtained a Shimano 600 NOS front derailleur that is a bottom pull unit. It will run with a same vintage Shimano 53/42 crankset on my 1984 Austro Daimler. I am replacing the Huret derailleur that came with the bike when new.
How do I proceed to set up the Shimano 600 front derailleur for proper operation? I know the outer derailleur side clearance to the larger chainring should be max 2 mm. But, how do I set the shifter, cable and the two adjustment screws?
Does anyone have a Shimano 600 (or similar) instruction set?
Thanks.

www.parktool.com repair section and Sheldon Browns stuff at www.harriscyclery both have derailer adjustment. Basically, with height and alignment correct,put chain on big cog and small chainring.adjust low limit screw so there is about 1mm clearance betweeen chain and inner cage plate.Attach cable with shifter in small ring position and pull tight enough to just remove cable slack. Adjust hi limit screw so chain will shift to big ring but not shift over it.

Thanks, I have checked those. My old Huret has a cable housing stop and the shifter cable is routed on the left side of the frame. The Shimano does not have this detail and it appears the cable needs to now route over to the right side of the frame. Does anyone have a photo of a same/similar front Shimano derailleur that can be posted. Right now I just do not see how to proceed with the install. Thanks.

Every shimano 600 FD I ever saw is bottom pull with the cable routing under the BB on the left side if the frame. Maybe you need to post a picture?

I concur. I have a Shimano 600 on my PKN-10E (sorry, Simplex fans!) and typical 1980s under-bottom bracket cable routing.

I do not have a photo. It is a Shimano FD-6400. There is no provision for a cable casing stop. Am I missing a part? My 1984 AD frame has no fittings for an under bottom bracket cable routing.
On the bike, the stock shifter cables are routed along their respective sides. The right/rear shift cable is routed under a brazed on guide above the bottom bracket. For the Huret front derailleur there is a cable casing stop brazed to the down tube forward of the bottom bracket. The short length of front shift cable casing begins and loops downward then up to the cable casing stop on the Huret unit.

It does not use a cable stop at the dreailer..... Assuming you have downtube shifter mount,or downtube cable stio, the cable with no outer casing runs from the shifter/stop under the BB,where there is usually a cable guide,but sometimes not, and then up th the derailer arm. Total simplicity. On some older bikes there may be a cable guide brazed on above the BB but the routing principle and setup are the same........There is no big mystery, missing parts or voodo here.The 600 FD is what it is,and if your cable routing is incompatible,then you have to make it compatible.

Got a look at some new bikes today.
There is a "missing" part. I bought a Shimano plastic cable guide to place under my bottom bracket. Unlike new bikes the 1984 AD frame with downtube shifters has no provision for this type of under bottom bracket cable routing.
Thanks for all the help.

There were frames that used no cable guide. The missing part referenced the derailer.
