and some cable for brakes and deraileurs. where in the heck do these cables go into those lever housings? any pics on the net that you know of? i've done Campy before but this Shimano stuff is mind boggling. thanks for any help in putting this bike together.
I can help.. (for once)Wannabe

Okay, having just installed a set of 600 levers just last night, I am familiar with this one! Best to do this in a well-lit area, preferably overhead light.

The brake cables (thicker cables) are thread through the front of the lever. Imagine pulling on the lever as though you were operating your brakes. You will see inside a small horizontal cyclinder with a hole through it. This "cylinder" kinda floats around in there with no cable mounted. The cable is first threaded through that (you will see which is the proper way to accomodate the cable anchor). As you thread the cable through, you will notice behind the cylinder a small hole (this is where the good light is critical). I think the hole has a black plastic lining which makes it difficult to see without good light. Thread the cable from the cylinder through that little hole, pull the cable when it emerges on the other side (near the mounting bracket) and continue to pull until the anchor se[a]ts in the "cyclinder." There, you are done with the brake cable.

Next, mount the brake/shift levers on your handlebar.

With the shift cable, the discription following is for the right (rear) shifter. Click the small lever at least nine times (if the shifter were operational, this would put the derailleur onto the smallest cog). Then, carefully move the big lever as though you were going to shift but do not move it so far to make it "click." If you look where the levers enter the hoods, a little opening will form and you will see inside another little hole sized to accept the cable anchor (not in a floating cyclinder this time). Simply thread the shifter cable into that hole and pull out the other side. Piece of cake. The key is to make sure that you have clicked the small inner lever at least 9 times first.

Also, with both cables, make sure they are lubricated prior to installation.

thank you, thank you - - -liv2padl

no wonder i couldn't find that darn hole, --- not enough light and didn't know about those 9 clicks of the shift lever. your description made it sound easy. now i'm going outside and give it a shot. if i run into trouble, i'll be back.

thanks again. dan

with the regular "long" cables of standard size, are two housing pieces, about a foot long, which have fixed plastic ends, one side with a really tiny nipple. these seem poised to go in a certain spot ... but where?
Well, hmm...Wannabe

Are you building a new bike with older components or are you replacing (upgrading) components on an older bike? Brake cable or the derailleur cables?

You will need cable housings for:

Rear derailleur cable for where it leaves the lever and goes through the housing stop on the downtube (where old downtube shifters would be). There should be no exposed cable between lever and downtube housing stop.

Front derailleur cable: same as for rear.

Front brake: from where cable goes into rear of lever (by clamp) all the way to the barrell adjuster (no exposed cable). The housing should slide right into the lever.

Rear Brake: same deal although some bike might have the cable exposed for part of its "journey."

Did you buy a new cabling kit? The STI cable housing will most likely need to be trimmed to a good length (I had to trim mine but still left 'em a little long). If you are re-using brake cable you should be good to go.

Now, as far as the housings go, they actually will slide a little bit into the levers (derailleur in side, brake in back).

There should be a third piece of housing for the rear derailleur cable from the barrell adjuster on the derailleur to the housing stop towards the back of the chainstay...

More info and I might be able to help you a bit more (what is the housing for?).

truth be told, i'm building up this bike for a friend of mine (i told him i'd help him out, thinking he'd bought Campy stuff). so he brings me his newly painted "old" bike, some old cable and housing and the new parts and cables. the drive train is all Shimano 600 --- what a surprise for me. i've never built up a Shimano bike in my life and it's definitely different from Campy. i can see where the old cable and housing is going to go --- there's also a difference in the cable size. there's some which is pretty thin and other which is "normal" size. i'm at a loss as to which is used for what. thin for shift? normal for brakes?

but it's these two small pieces of housing that now have me puzzled. they're short .. like perhaps a foot long and have a piece of nipple like affair on each end. almost like those silver nipple things i'd have used on the end of a Campy housing. because they're so short they can only work for a few things ... they're either for the brakes .. to run from the lever to the cable adjusters on the down tube ---- or one is for the loop from the chain stay to the rear derailleur. this option leaves one housing left over so, i'm thinking they must be for the brakes.

i think what i'll do is use your instructions and then come back to you with the results.
cable and short housings...Wannabe

Well, first of all, the two grades of cable, as I mentioned before, the thin cable is the shifter cable, the thick cable is the brake cable.

The short housings, well, the shortest one is usually the part that goes from the barrel adjuster on the rear der. to the stop on the chainstay. The other derailleur housings are probably the same length (when new) so you should be able to figure that out. The next shortest piece is most likely the front brake cable housing with the left over piece (and most likely the longest since we're talking about an old bike where probably the enitre brake cable from lever to barrell adjuster was housed) being the rear brake housing.
