2-56 pan heads
Locked
 
|
During the assembly of K3 #3212 Front panel on page #29 requires 2ea
2-56 black 1/4 6.4mm pan head screws and #2 split lock washers to mount the stand-offs under the LCD. These screws were missing from the Hardware bag. There were 2ea 4-40 black flat head screws in the bag. I found 2ea 2-56 black pan head screws in my Junk Box, however they were shorter than 5.6mm. In order to install the stand-offs the #2 split lock washer had to be left off. Is this action going to cause an issue later?

They're typically not in the hardware bag with other screws but a separate small envelope. Carefully check everything supplied. 73, Bill |

If I recall correctly the "missing" 2-56 pan head screws (used in the front panel board assembly - pg 24) are packed with 2-56 screws that are used for the VFO A trim panel (page 31). Unfortunately, if the user sets aside the separate envelope with trim panel hardware until it is time to install the trip panel (to prevent loss of the 2-56 hardware), he will not find the "missing" 2-56 hardware when needed to attach the spacers to the front panel circuit board. I had that problem with my K3 .... and this is the fourth or fifth report of the same problem here. The assembly manual needs an explicit statement on page 24 indicating where to find those screws. 73, ...

Ditto here. I built a K3 for my club a couple of months ago and had the
same problem. I found some screws in my "can o' screws" that were the right size and used them. Then I found the screws I should have used. Definitely needs a comment in the manual. 73, Alan N5NA Joe Subich, W4TV wrote: > If I recall correctly the "missing" 2-56 pan head screws > (used in the front panel board assembly - pg 24) are packed > with 2-56 screws that are used for the VFO A trim panel > (page 31). > > Unfortunately, if the user sets aside the separate envelope > with trim panel hardware until it is time to install the > trip panel (to prevent loss of the 2-56 hardware), he will > not find the "missing" 2-56 hardware when needed to attach > the spacers to the front panel circuit board. > > I had that problem with my K3 .... and this is the fourth > or fifth report of the same problem here.
