Evening Peeps
I am struggling to find where this ' extra ' piece goes ?
My headset appears to loosen ( the round bit with grippy edge ) - keeps coming loose.
I am a bit of a novice here, any help appreciated
thanks guys

here is another photo.....
so where does it go ?
everything ' seems' to work ok....
however the ' round piece with cerrated edge' seems to come loose...????
-
I would hazard a guess that that crown race should b on the forks and ur bearings look like they r in upside down :daumenhoch:

That bit in your hand looks like the fork crown race, there may already be one on your forks?
If not it slides over the fork steerer the opposite way up to how you're holding it in the pic, the bearing race faces upwards
The bearings should be fitted with the cages in the cups and the balls (ooh err) facing outwards
If the top nut is tightened all the way down in the first pic you'll need a washer below it to keep the adjuster tight it'll never stay tight if there's a gap
-
As per above :daumenhoch:
Here's an exploded view of one (yours probably won't have the 'seal' bit):

Superb stuff - cheers

I do have the washer pictured above - but if I remember correctly it sits snug within the cerrated adjustable race part of my headset . The diameter is smaller and fits on like a glove.
Surely because its ' inside ' this piece - it's not doing anything ?
Cant take any pics - as I'm at work unfortunately
Cheers addy
-
Beartrap headset then? Yeah the toothed washer slots down on top into a recess on the adjustable race. What it does is stop your headset loosening over time.
-
Not too sure what it is bought at MK13.
But you've described it spot on Dannywhac....
Ok so why is the adjustable race still loose ?
Should I buy an extra washer, larger in diameter to sit on top of this - to stop it moving ?
Tad confused
-
It doesn't look like a bear trap 2. If it is you have 2 washers missing, one with the all important teeth that lock into the upper adjustable race. You're best off taking it all off and take a pic of all the pieces plus the bottom of your fork shaft and we'll talk you through it :daumenhoch:

Cheers thatswanguy
Will take it apart tomorrow morning.
Thanks all

I must of bought this off ebay - and found a picture !
looks like this piece sits on top of adjustable race ?
will give it a go - and check all the balls are up the right way etc....
-
that bit in your hand on the first picture is a fork crown race.
looks nothing like a locking nut to me :-\
-
i know what your saying pickle and tried that - but as you can see from photos - it just didnt ' sit ' at all right and was clunky.
i have since tried it the way as in diagram and all is absolutely fine, ill post some piccies.

this is what it is set up at the moment - and seems to be all snug as a bug.
this piece does look like the crown race - but it seems to be doing the trick as the washer ?
OR AM I JUST A TOTAL FOOL ;D
please let me know your thoughts / feelings - I am off to rom skatepark on this tomorrow >>>!!! ??? !!!
-
Right fella...take it all apart and have a look at your forks to start with. They should look like this....
(http://i39.tinypic.com/23usv1d.jpg)
That spare bit in your hands should be on your forks, as in my photo, is there one on yours?
-
Ignore my reply, i see your crown is in place :daumenhoch:
-
yes its there deffo
-
It shouldn't be on there it is a fork crown. All headsets come with one and your forks may already have one fitted, therefore it is a spare part.
-
I think - there was a piece missing....when it was sent to me ?
but this ' remedy ' seems to be working a treat - with the adjustable race not becoming loose as before....
....and if i dont get out riding this weekend - i will cry.
i know it doesnt look right - but it will get me out on the road / skatepark and enjoying the bike - until i buy a new one.......
waddya reckon ?

+1, stick it in a drawer, you don't need it.

Fair point. If it works put a stem pad over it :LolLolLolLol:
-
thanks for all your invaluable help fellas !
i am still learning all this - BITD - My pops done everything for me.....
ddaaaaadddddd can you fix my biiikkkeeee ! ! ! ! ! ! etc etc......
loving the learning.........but really just wanna ride this weekend.....
-
I think your problem is due to the fact that the lock nut will not tighten up against the lock washer as the nut is hitting the top of the fork thread before it tightens,so using the crown race as you have as an extra washer has given you the clearance you needed,it would look much better though if you use one or two extra lock washers.
-
Someone could have used it as a large spacer if the steer tube length was a little longe
-
Nice one jp rebel will check my local bike store for that
