i have a problem with schwinn suburban headset

so im trying to get the headset on this schwinn suburban. the problem is every time i turn this nut it is to tight to turn the whole fork.



so i loosen it just till it is just snug then i install the shifters and then top nut. and when i tighten the top nut it it still binding, i know i greased up the bearings enough and i know they are sitting correctly. as the are the only way that they will fit. also when i go to pull off the top nut it is super loose after turning the fork some, when i pull the shifter off the nut below is loose... it doesnt seem to be holding for whatever reason.





here is the orientation of the bearings. i know the pics dont look like there is alot of grease i wiped some off to show you how they sit. what am i doing wrong...

Try to keep the top bearing race just a bit looser, that way when you tighten it down it won't bind up. Those headsets are a bit of a pain since the bearing race does not have wrench flats.

+1 Sure looks like you are missing a washer/spacer on that set up. My Suburban already moved onto another home, or I would take a look.

But there was not a cable holder on my Suburban, I just checked some of the pics I kept. As I recall, there was a spacer/washer below the shifter bracket.

There is supposed to be a washer with a small protrusion to fit into the fork tube. Then put the nut on and see if that doesn't solve the problem

The knurled "nut" is upside down! I believe the concave section should be facing down and into the bearing. It's actually a bearing race. Tighten till snug put on the shifter bracket then top nut and tighten. I think?

thanx for the help guys... also i don't think there is another spacer. i was thinking the same thing. and i looked through the parts bag i separated it into and saw nothing.
i also was able to dig up a pic i thought i trashed of the headset... doesn't look like any spacer is there. i know the shifter has the groove that the spacer would have... i figured it took the place of the spacer.


are the bearings in the right way, i always forget the way they sit...

I second that. Top bearing looks upside down.

Outside bearings go into cup; Inside bearings go into race. Looks like there's a race where the cup normally is.

+1 The top bearing would be upside down if you had a traditional/original headset. But this replacement headset is quite a bit different. I haven't seen one like that before.

I have run across headsets like that on 2 Schwinn Suburbans, my Lotus and a 80's World Sport. It's a little bit goofy.

mainly, think about where the bearings come into contact with metal. if u put the cup on top of the bearings the way you had it, it would be metal on metal, instead of bearings on metal.
