Head tube is a little chewed/tight
« on: April 29, 2008, 02:50 PM »
Just had an Ammaco team pro frame arrive and it was unfortunately showing itself out of the box  :( so a few prangs in delivery has squeezed in the headtube a bit. Does anyone have any tips to pull it out a bit to get a headset in there?

Cheers,

Matt  :daumenhoch:

Rob, bought off here mate but by a good fella Chris (strikey). Told him already but I didn't want to trouble him really with it. Was delivered by DHL so hopefully Chris is covered but it may not come to that if I can find a way to just open up the headtube a bit.

Cheers,

Matt  :daumenhoch:

Bearing cups should push it back into shape if you use a bearing cup press to ease them in provided it's not totally fooked.  How far out of shape is it and any pics to see how much damage there is?

a headset press hass different sized presses on it, like a pyramid, but round layers instead of square. perhaps the pres without the headset would push it out a little.

Its not totally fooked but enough to prevent me from wacking in the headset and trust me i've tried. Its perhaps squished in only a few mm or so...   :(

Whereabouts are you, I have a headset race press like the one the Fruitster describes with staggered presses to fit different sized races, might help  ;).  I'm in Iver Heath, Bucks.

try your local bike shop swivel, they'll have one and shouldn't really charge you to do it

but for fooks sake not Halfrauds as they'll just take a chissel to it!   :shocked:

had the same before mate , if its not too bad get a pair of pump pliers , put a rag in the tube,  push the pump pliers in and open them up against your frame tube (gently ) in a levering action basically pulling the pliers apart and bobs your uncle.. job done, dont over do it or you,ll need a oval headset :D

Have used a round bar before, levering from approx the middle of the head tube and rolling/pushing the dent out, again not too hard, this works best if the dent is at the front of the head tube. Bit of a bodge but worked in the past. The fatter the bar the better.
