    Can someone tell me which bearings go on top & bottom in the head tube? Large or small? How many bearings should there be? I may be missing some?



    Thanx Much!

    Just went out and looked at my stock forks hanging from the rafter of the shop. My bike is an 06 and the bearing are in a cage. The larger balls appear to be set on the bottom race. Gerry



    Take care my Friend.........

    AllBalls is the answer to your question.

    If you go to order new parts, what you're looking at are actually called "steering stem" bearings.



    I looked at the parts diagram and it confirms what Gerry reported that the small ones are on top and the big ones are on the bottom. Unfortunately, Yamaha doesn't sell the individual balls, just the bearing retainer assy. that already has the balls loaded up into the cage.



    New ones are about $22 for the top & bottom set, but as qwerty mentioned the AllBalls tapered roller bearing replacement parts are the way to go and can be found for about $15 more. The tapered roller set is a far more robust configuration than the OE ball bearing setup.



    I've used the AllBalls steering stem bearings on several old KZ's in the past and it totally eliminated any notchiness felt in the bars and made the front end less twitchy; felt noticably more solid. When the time comes that my triple tree gets removed, I'm swapping the TW over to AllBalls whether it "needs" it or not.



    Best of luck,

    Mine is an '87. Has loose balls. I hate when I lose my balls! Maybe I should put my balls in a cage? Or just take my balls and go home?

    Well now, that's a horse of a different color!



    22 balls on top & 19 balls on bottom.









    You know, the only difference losing your balls & loosing your balls...is that extra "O"!

    I guess that would be big balls on bottom and little balls on top? I may be missing a couple of balls?

    When you go to reinstall your missing balls, slather grease in the bearing cup and it will keep your balls from getting away as you put it back together. The sticky lube is the key to keeping those balls where they belong.

    If you have an 'old world' bicycle shop in town, you maybe able to get some new balls (set) that are close enough to work for you. I am as well using a roller bearing set on my TW/Tri-Z forks. If cash is tight, you can Pay Pal me $7.00 and I will send you my stock 06 set first class mail on Monday. Gerry
    Take care my Friend.........

    Loose balls are listed products from the major bearing manufacturers. Here (Cape Town) I can get them from FAG & SKF at least (not tried the others ever).
