Changing cams / springs in Gunfighter Mk II

Postby Murrdox » Thu Jan 04, 2018 18:35

Hello,

I'm changing the cams and springs in my Gunfighter for the first time. I ran across something odd and wanted to post it to confirm that it's correct, and maybe hopefully inform other new VKB owners.

In the GREEN circle you can see the Y-Axis spring and cam which I have successfully changed out from the 10 cam and 20 spring to the 30 cam and the 30 spring. Note how there is a nut that is holding the bearing in place. Now, in the RED circle, note the X-Axis bearing. Note how this is NOT a normal bolt. It has a spot to be adjusted with an allen wrench, but the two allen wrenches provided by VKB with the Gunfighter do NOT fit this bolt. Like most people I have assembled a large amount of IKEA furniture over my lifetime so I have a pretty good supply of allen wrenches. A 1/8 allen wrench is too big for this nut, and a 3/32 is too small! I don't have a wrench to fit this bolt.

The Gunfighter instructions advise to remove the bearing before replacing the cam/spring to relieve tension on the spring before you remove it. At this point, it doesn't look like I am able to do this with the X-Axis bearing!

Am I missing something?

Most of the world uses metric system. Try finding metric allen keys. The one between 1/8 inch and 3/32 inch could be 2.5 mm or 3 mm.

Only basic adjustment and replacement hex/allen wrenches are included in the retail kit. If you want to go further, you will need to look for metric tools.

When I opened up my Gunfighter base for the first time I rounded off the hex wrench that came with the base because the bolts were driven down so hard in the factory. I had to pull out my moderately better quality set of hex wrenches and then was able to open it up. So I stopped using the little tools provided out of necessity.
