Headset Wrench

Headset Wrench
Sears bike made in Austria buy Puch?

This bike has a very different "nut" holding the handlebars to the headset. Instead a nut to be loosened with the crescent wrench, this "nut" does not have flattened the sides for a wrench but a special key slots as the that about one crank and bottom bracket. There are 3 slots. 1 11'oclock, 5'oclock and 7'oclock. Does anyone know the name of this type of wrench and the size you need, and where can I buy one, so you can raise the handlebars? Please take a look at these images of 1 of the slots and "nuts. http://www.flickr.com/photos/27544233 @ N03 / Thanks in advance for your help.

What you need is called C-key. (Some people also call it a key Hook.) Unfortunately, I can not know the size you need. In any case, here is a picture of one on the website of tools for repair crankset Park. http://parktool.com/products/detail.asp?cat=25&item=HCW-5 Here's another photo. http://faq.f650.com/FAQs/Photos/SteeringPhotos/SlottedNutTighten.jpg In general, if the bow of the key does not fit the arc of the nut exactly, still work. The important thing is the hook of the key slot fits quite well and not try to pop out of the slot to apply pressure. If the arc of the key is so far from the arc of the nut, who wants out, you need to find another key. Hopefully you get the point. BTW - Linkwray is correct. You should not need adjusting this nut to increase or decrease after the handlebar stem. The nut in question is used to adjust pressure support the receiver. The pen is mother held in place by a screw binder. To loosen the screw folder, do the following. Loosen the screw on the top of the stem of several laps. Place a wooden block on top of the bolt. Gently tap the wood block. Repeat the process twice if necessary. This should help then up and down the stem. To tighten up the pen again on the headset, simply press the top screw. A minimum insertion line is inscribed around the stem. Do not lift the trunk above this line. Doing so will not be enough to stop inside the head tube to make sure everything stays together. There are few worse than having your handlebars are separated from the rest of your bike during a high speed descent! Hope this helps.
