Kearney & Trecker question

dana gear · Nov 11, 2016

I currently own a Kearney & Trecker model K-2. The over arms are 4.125 diameter and the width of the back dove is 12 inches wide, 50 taper.
There is a K&T vertical head for sale that came off a K&T model CK3 in another state, my question is will a CK3 vertical head attachment work on my K&T model K2

No,

The head itself MAY work but, the bracket and drive are quite different in size and location.

Find out what head is on the 3ck, get a serial #. Post a pic.

Your over arms are NOT 4.125 - they are 4.250

3 CK over arms are 5.000

This book categorizes drive brackets for various machines....See if the two machines you are considering fall in the same column...

The heads can vary usually by drive bracket configuration...

Thanks for the link Ramsay.

Did I miss it or is there no 310ch in that manual? What am I missing?

We have a head from a 3CH and it fit our 2XX mills, I will check the #s and get back.

Thanks Ramsay, you're the greatest.

I see that a 3csm (20) is in the same column as my 310. Do you happen to know if a 3csm(20) and 3csm(30) have the same width of ways that the knee travels on?

No sorry ... Check with Vintage Machinery in the K&T section.. Maybe someone else posted it..Ramsay 1

A slightly later example (1957 - when CSM was no longer offered) shows the TF 320 and TF 330 differing by 2000 lbs - suggesting a somewhat larger machine.

What number K? A 2k?

A 2K/2CK shares 4.25" over arms with 3H/3CH

jdavi581 · Nov 17, 2016

I assumed it was a 2K, just because of the size, smaller than the 3CH but a # 50 NMTB
