Re: [Elecraft] K2 main encoder wanted

I would suggest Break-Free CLP, It works great and has a lot of uses.

It works quite well and last a long time.

WD40 is a preservative, not a lubricant.  It will act as a penetrating 
oil, to free seized parts, but for a longer term solution you want to 
look at sewing machine or hair clipper oil.

WD-40 is a penetrating and moisture displacing oil, but over time gets
gummy so is not a reliable long-term lubricant.

Re: [Elecraft] K2 main encoder wanted

[Bob G3PJT]

Hi everyone

I have managed to get the encoder turning reasonable freely. I put a 
very small amout of WD40 on the shaft where it enters the housing bush.


And then did as Don suggested repeatedly and firmly pushed the knob up 
at the low point. After quite a lot of pushing it began to loosen up a lot.


So I feel I have a working encoder again and am going to use it for a 
while and hopefully  I won't need to replace it.


I was pretty concerned that pushing it back would damage it further but 
it works OK


73 and many thanks for all the suggestions

Re: [Elecraft] K2 main encoder wanted

[Harry Yingst via Elecraft]

I really haven't looked at the encoder format they are using but if you can 
figure it out than you may find an alternate encoder.
The Elecraft one may be pricey because it's a 100 (25 I believe in reality) 
pulse per rev  but there are a number of them that are 34,64, etc that can 
typically be had for much less.

It contains the new encoder, a new knob and several other components

If this is your only option, be aware that the spacing between the new 
encoder board and the back of the Control Board is critical.
You must flush trim the leads on the Control Board where it can 
contact the encoder board and also flush trim the encoder board after 
it is assembled.  Flush trimming means really flush - diagonal cutters 
are not sufficient.


You will also have to enlarge the hole for the encoder in the Front 
Panel metalwork a bit.  A knife run around the hole a couple times 
will allow the encoder shaft adequate clearance.


You might want to put a piece of "fish paper" between the encoder

Re: [Elecraft] K2 main encoder wanted

Bob,

You can get the new encoder from Elecraft - it is p/n K2ENCASY.
It contains the new encoder, a new knob and several other components as 
well as the encoder board.


If this is your only option, be aware that the spacing between the new 
encoder board and the back of the Control Board is critical.
You must flush trim the leads on the Control Board where it can contact 
the encoder board and also flush trim the encoder board after it is 
assembled.  Flush trimming means really flush - diagonal cutters are not 
sufficient.


You will also have to enlarge the hole for the encoder in the Front 
Panel metalwork a bit.  A knife run around the hole a couple times will 
allow the encoder shaft adequate clearance.


You might want to put a piece of "fish paper" between the encoder board 
and the Control Board.
