Does anyone have instructions for these? Here's a picture of what I have. It looks to have sealed bearings, but it has 2 inner rings with 2 set screws. There's also a bag with 3 long screws & 3 nuts.

Any help would be appriciated!

I believe you need to measure the BB shell width first.
Then set the inner collars and bearing shells up using these measurements.
Take one bearing cup off and slide the whole lot in the BB shell.
Then put the bearing cup back on.
Slide the 3 bolts through both sides and tighten using nuts supplied.
Make sure theres sufficient clearance for the crank arms against the chainstays.
I'm sure someone might have the written instructions but that might help in the meantime.
#Note, I have never used this style BB and I'm just going by the pic you supplied.

that's not the correct spindle/BB. the 400s took a proprietary spindle (along with a few other sugino-made cranks). what you have won't work.

Hmmm, I need more help. Here are a few more pictures. I guess my first question is are these Redline Flight 400 cranks?
Is the spindle the only part that won't work or are you talking about the bearings/inner collars, bolts, etc...

Please help!!!
Thanks, Steve

Dude, cool bullseye bottom braket. I still have mine from back in the day. What it won't work? Thats a bunch of BS. Simple to use. The big cups fit into the frame (American Standard BB) and you use the inside small circlular cones to space out the cups in the frame. Slide them into place so that the cups are flush with the frame. Put them into the frame with the long bolts hold it all together. With the bullseye BB set in place you just slide the cranks on and tighten them with the larger bolts. Nice set of cranks by the way. If you want to sell them let me know. I was going to use a set of 400's with my bullseye bottom braket. The BB is compatible with any of the old style three piece cranks like sugino, tourney, maxy cross, shimano, etc that they made back in the day. That is going to be one nice setup. Look at the pieces again, you will figure it out, there is only one way to put all that stuff together.

Thanks getset, I follow what your saying. I bought these off ebay about 2 weeks ago and sent the arm out to get re-chromed. The only thing that is confusing me is the inner collars. They have 2 set screws in each one which looks to hold the spindle from sliding side to side but the spindle is smooth so there's really nothing to bite on. I can't imagine these hold the spindle in place, but they must.
Getting the crank arms on is obvious and I have new dust caps, but it looks like there is going to be a little difficult to line up the spindle so that the chain ring (sprocket) lines up with the freewheel... right?? or am I still missing something.
The seller has mailed me a set of instructions but I haven't reveived them yet.
Thanks again!!!
I'll put it together the way your saying and post another pic in a few minutes.

What Mr. Coasterbrake is trying to tell you is that Redline 400 series cranks have their own specific bottom bracket set. The spindle taper is the main difference. If I remember right, the Redline square taper is larger than most others. It looks like you have a sweet bottom bracket there that will work with a number of crank arms-just not those.
Check to see how the arms fit into the spindle. If my memory serves me correctly, the Redline arms will be a loose fit on the spindle you have.

The way you have it in the second picture is correct. If you were taking it apart it would be, big bolts that hold the cranks, next crank arms, long bolts, cup with bearings, then you could pull the spindle with the small circles with allen bolts. These inner small circle shafts with allen screws hold the bearing cups in place. adjust the spindle left and right so you can adjust it for the type of frame you have. I imagine if you put them in as is (centered) the spindle side crank would be too close to the frame or the chain might be off center and rub the frame. They are the same type of bolts used on the outside of bullseye cranks. No there is not anything on the spindle to hold them in place other than the bolts themselves. It is very basic. That bolt fastens to the spindle and keeps it and the bearing or outer cups in position. If you need the cranks to have more room left or right to clear the frame you would adjust the inner circle bolts on the spindle to move the spindle more toward that direction. Thus if you need more room on the crank side you would move the spindle (pull it to that side) and adjust the inner circle deal to hold it in place. Just put the spindle and cups in the frame with sproket side on and adjust the clearance. I think you are over thinking this man. I wish I could show you, you'd go, oh yea, dude I see how it goes, that makes sense. Anyway, I tried doing some engine work following an example once and could not figure it out until a friend showed me. It's a cool bottom bracket to be sure. I found the spindle was a little short for my PK ripper and retired them when I bought 401 cranks for my GT. The 401's use a different spindle.

Smoken Steve might be right. I never tried the 400's on this bottom bracket. I was just looking at the similar taper and figured they used the same standard size. Have you tried putting the cranks on the spindle. If it is not snug go no further. You would ruin these cranks if you put them on the wrong size spindles. It should be a real snug fit. Sorry about that. I was assuming you had tried that already?

Thanks guys. Here's a mock up of how I think they go. Let me know if you see anything wrong. The spindle seems to fit the crank arms snug. I'll go double check and post another pic.

Looks and feels snug to me. Take a look at the pics. There is no play. With the bolt tightened up, they are rock solid.
Do you still think this is the wrong spindle?

That looks totally cool to me. I couldn't see it getting any closer than that. What do others think? Are the crank arm to close to the frame when mounted? That looks ready to go to me, maybe just some adjusting of the spindle with those inside circular spacer things.

I get what Mr CB said but it looks like you have a BB to suit the special Sugino spindle. Lucky you.
I am pretty sure the nuts go on the non-drive side too.

COASTY, thanks for letting me know the screws were in backwards. I'll make sure the nuts are on the opposite side when I install them.

If you look close at the spindle, it does show some wear, where the small collars would go (silverish stripes) and the crank arms were slightly worn before I had them re-chromed. Whether or not this whole set was installed as is or not, I don't know. I did e-mail the seller from ebay to see if I could get more info about the history. He also mailed me the instructions, so when I get them, I'll post them.

At this point, I think it will work. If anyone still has doubts, PLEASE let me know!!! I really appriciate the help!!!

That I don't know, I haven't got that far yet. Is this what Mr Coasterbrake is talking about... the length of the spindle is too short?

the spindle for 400s is bigger across at the square ends. the arms should not slide on as far as they do with your current spindle. if you are just building a show bike that will not be ridden, what you have now will be fine.

if you ride it, it will work loose and damage either/or the spindle/arms. under load the current setup is not a snug enough fit. you have to trust me on this, if you don't want to ruin some nice parts.

Thanks for clearing this up.

Anyone know where I can get the correct spindle?

Ok, I believe I found Flight 400 repro spindle with bearings, etc... & spindle alone. Do these look like the correct parts?

Thanks for your patience with this thread!

Yes, thats from Biagio. I've ordered one and its a perfect match to the original BB setup....

that looks like it. sugino made the oversized one (like you need) and a standard sized one for use with most other square-taper cranks. i can't tell from the picture which version that is, but it's listed as what you need.

Yes that one from Vert-ego is what you are looking for. Like was mentioned if you dont plan to ride on them ( or very limited riding ) the Bullseye will be ok. Keep in mind that the bb from vert-ego is a repo and a very expensive one at that ( almost $ 250.00 usd ). I would just use the Bullseye until you find a original.

Yea, not cheap, but already ordered.
Thanks
