Harry: I went digging through all of L. William Rehm's posts for the benefit of Matthew Pramas who recently raised the question in the Sandbox. Mr. Rehm posed the problem elegantly in response to a suggestion from Art Aytay by posting the following photo:
Kraig suggested the following fix:
with the accompanying text:
Bill R., please excuse the poor quality sketch, but this is what I was suggesting in my post below. A simple plate, actually two of them, one for each side, each with two holes and a welded on stud. This setup would allow use of the QA42A on a non-QA equipped narrow frame with no mods to either the tractor or to the implement. Well the implement might need subtle "tweaking" of the subframe . . ..
[Continuing] Gerry [Ide], on my QA42 there's enough wriggle room for a thin plate perhaps 3/16" on each side but a thicker plate might need some "tweaking" on the subframe to allow room for the adapter bracket plates. But then, my QA42 might be "tweaked" slightly already. OR One could make the plate so that is is spaced out from the frame and the stud faces inward toward the frame so that the snowthrower sub frame slips behind it.
A few days later, L. William posted that he was going to make a trip to see Scott Madson, and Jeff Derstine immediately posted the solution he came up with:
with text accompanying:
All you need is this simple adapter which will bolt to the back two holes in your 122. Make the outside plate out of 1/4" thick material, a 3/8" thick center plate (to replicate the spacing of the frankenstein bolts) and a .100 thick inside plate to duplicate the washer thickness of the frankenstein bolt. The red holes are 17/32" (.531) and the blue pin is 5/8" diameter (frankenstein bolt). Center distance is 2" between the 17/32" holes and an additional 2" to the 5/8" pin. This should work perfectly. In fact, I'll be making a set for myself for my own 122.
I think Mr. Rehm basically implemented Jeff's suggestion. He eventually posted the solution you have shown below with accompanying pictures showing the parts.
Mr. Rehm wrote:
The pieces, before I removed the "inner" 1/8" piece of bar stock. The inner bar was giving me fits trying to get the bracket installed without pulling the engine. May not be too pretty but once I get a longer lift rod, I'm cookin' with gas!
I think I have all this straight. Most of the valuable discussions occurred July 8-10, 2010 with Mr. Rehm posting his solution October 20, 2010 after your urging on September 22, 2010. (Note: L. William Rehm's first post on the topic was on December 21, 2009.)
Since the consensus seems to be that the mythical IH "Adapter" either never existed or at least did not contain the necessary part, I thought it would be worthwhile to pull everything together on one page.
