I have a newly acquired 1972 301 industrial tractor with what appears to be a 401 loader. The six bolts that hold the front sub-frame to the engine block have stripped. I am in the process of adding thread inserts to repair the stripped threads, but have noticed that I may be missing the additional support braces that go between the flywheel housing and front sub-frame. They appear to have been on the tractor at some point, but not now. JD part numbers for the braces are T21653 & T21654.
I plan to make these up from 1/2" x 6" steel plate. My question is concerning the mounting of the plates. There are two 5/8" threaded holes on the flywheel housing for the rear mounting points and I am guessing that the front mounting points are supposed to be behind the two tabs that serve as the front loader frame mounts which are bolted to the sub-frame in front of the engine. The issue I see is that there is a step cast in the tabs that corresponds to a step in the sub frame. If I slide the steel plate behind the tab, it will make the tab stick out further. This in turn would widen the loader frame and possibly make it impossible to mount the loader arms back on to the loader frame. Any thoughts to how the braces were mounted?
I've enclosed a picture of the right side loader frame mount. The darker unpainted area to the left of the mount (below oil cap) is where I assume the front of the brace attaches.
Thanks in advance.
