[Hallicrafters] Fluted wrenches

[Jim Liles]

Service note:

If you are going to remove the small knobs on the Hallicrafters radios, or are going to re-time the VFO on the SR-2000, 400, or 400A you will be using a small 4 flute wrench.

There are two sizes that will fit into the set screws.  A .069” and a .076” 4 flute wrench.  The .069 will remove these screws if they are not tight.  If tight, you will think that you stripped the set screw.  Not so, the .076” wrench is the right size and will work.  Do not use the .069” wrench!  

If you are working on the SR series VFO back lash or other gears, buy the Xcelite four flute .076” wrench.  It is in a screwdriver handle and is 4” long --- a life saver.

They also have all of the other flute sizes for the handle. 

Kindest regards  Jim K9AXN
