Title: just distroyed a PK...
Post by: meticulous on February 22, 2009, 07:44 PM: well nearly..... trying to get a suntour stem on, it would not go on, it seems the fork tube is to narrow by about a millimeter, which is a fookin mile out in engineering terms, started tw.ting it with the lump hammer in a frenzy,dont like being beaten, but would not go past the wedge angle, there is now deep gouging in the stem shaft, which ok, is hidden.... but it fookin pis.ed me off..... :2gunsfiring_v1:

just thought i would share my anger....

Post by: ron burgundy on February 22, 2009, 08:43 PM: easy tiger... the fork tube may require a good clean out. I had the same issue, gave it a good scrubbing with a wire bottle cleaning brush, job sorted :daumenhoch:

yep! its not needing a clean out, it is the wrong size, was whakking it with the lump hammer, will have to put the tuff neck back on.... :'( i just fancied a colour code change..... thanks

Post by: JT71 on February 23, 2009, 02:42 PM: is it a powerstem?

I've had the SR stems in two different sizes, one had a fatter shaft by .2mm and wouldn't even go through the headset locking nut.

Check the internal diameter of the forks, it should be 22.2mm or slightly larger and then check the diameter of the stem shaft, that should be 22.2mm. I'm guessing you'll have a pair of verier calipers?

Post by: meticulous on February 23, 2009, 06:45 PM: lol, no i havent, but here the evidence....

couldnt even get the lock nut on....

thats as far as it will naturally go in the forks, without force....

even scored the inside of the landing gears....

Post by: snav69 on February 23, 2009, 06:50 PM: The shaft must be too thick as i had no problem at all with my powerstem and lock nut ;)

Try a different stem ???

Post by: Bigplinky on February 23, 2009, 07:13 PM: I've had one that taper internally from about 2/3 of the way down so you can't get long shafted stems in but never ones that the stem won't start in, sounds like a duff stem to me.

Post by: meticulous on February 23, 2009, 07:18 PM: its not duff!!! went on my gt ok....
