I finally got the pivot pin out of the pedestal. The bushings were paper thin. The axle extensions had been (badly) welded in to the axle tube, and the wedges were bearing against some 1/4" round bar welded to the axle tube. The tangs that the u-bolts clamp down had broken off and were welded back to the axle tube. However, these welds are badly cracked. The rear pivot bushing retainer weld looks like it had been "reinforced" too, so I'll grind it out and reweld. The left hand spindle has been welded in the lower bushing area and ground down with an angle grinder -I gues that explains the quarter-inch play. Also, the idiot that did that welded up the lube holes. It went into the machine shop yesterday for restoration. I have a couple of questions on the pivot brace. First, what is the size of the flat bar that the brace arms are made of? Mine was cobbled together from some old plow parts (with the same terrible welding); the last foot or so towards the axle might be original & it is 5/8" x 1 1/2". I intend to fab up some new ones and would like to use the original size. Second, the rear support for the front axle brace doesn't look like anything I've seen on a 44. It is a fairly elaborate casting and has a ball & socket joint for the brace. That end of the brace has a 2" x 2" x 4" solid block of steel that the ball stud goes through and is retained by a large locknut on the front of the block. The brace arms are welded to this block. The bolt holes on the casting exactly match the holes on the 44 frame. When I pressure-washed the decades of crud off it, it had yellow paint. Any ideas what it might be from?

Your MH bracket under the engine pan, that bolts
up perfect,might be from a MH 404 Work Bull. This
is the Industrial version of the '56-'57 444. The
ball socket arrangement surfaced there. Trying to
figure your other parts: Do your spindle shafts
have only clamp tops for the arms that the tie rods attach to, or do you have large hex nuts on
top of the spindle steer arms? The support brace
from a 404 would be too short, thus, yours is pieced together. Any casting #'s on spindle arms,
heavy cast steering support? The center tube is
either 36", or 44", correct? Pivot pin rusted?
Tube clamps vary, depending on the WFE, answers to
these questions will help in giving you advice.
Kindly post back. Good luck.

I think you may be right about the 404 Work Bull. Numbers on the rear brace are 768047 M1, and MHF; Massey Harris Ferguson I expect. It is also stamped "Canada" and "K90-5". The spindle shafts have large hex nuts on top of the steering arms, and the arms have casting # MH 764136 M1. The axle tube is 44". The pivot pin was not rusted at all, just very tight. I suspect it was tight because it jammed against the destroyed bushings. The zerk fitting was missing and I don't think it had any grease for many years. The tube clamps are in good shape. The saddles of the clamps had a MH number on them but I didn't write it down.

Your bushings have probably been under severe stress, due to lack of proper brace support. The
"pivot stud bracket" is the 404 style: ball,
retainer dust seal,shim plates,1 1/8" Hex nut &
washer. Your # matched it. The steering arm # is the correct 44 set up, vintage'49-'55. Correct
U-clamps are 5/8"x 14 1/4". Improving the brace support, will have to happen, after you get the axle bushings, repairs complete. Then, you can measure distance: lifted, next under load. Since you have mixed parts, no exact measurements exist.
The 444 used a different front axle(no help). I
see 3 'possible' shim plates, .015;.030;.060; Your
new brace length will determine required shims.
Post back on grey areas, before we forget the
present problems and the planned solutions. Good
luck.

I still am repairing the axle tube. A careful inspection found a few cracks that all have to be ground out and filled. The saddles on the U-bolt clamps are marked 761805 M1, which I believe is correct for my tractor. I will dive into the pivot stud bracket after its back on its wheels. I am unsure what to do about the tie rod ends, especially the long ones. Mine are marginal. I think I could fabricate a sliding sleeve that would use conventional threaded automotive type tie rod ends on both ends, but I'd have to find a tie rod end with the same ball stud diameter and taper. Thoughts?

Saddle clamp number is correct. Assuming you have the correct tie rods, the ends can be after market
Tisco. For inner, MF 35, outer(w/ample shaft)
Ferguson 40. Your MH steering arms have plenty of
material, but the tapered hole is too small for
the F40 bolt. Without compromise, you can open these tapered holes, upsizing for the F40 parts.
A machine shop can do this, in ten minutes, more
detail for you to enlarge a tapered hole, w/out
their shop equipment. These must remain tapered.
Concerns also, on the 1/2" hex bolts, securing
the tube adjust wedges. Wedges wear, without the
2"x1/4" flat stock steel welded over user hole,
old wedges fail to perform. Adding 4,(top & bottom), will stabilize the tube extensions. The
lower wedges seem to show noticable wear. Good
luck.

Outstanding advice on the tie rods. Thanks! For the outer rods, are the Furguson F40 rods for an adjustable front axle machine like mine - will they slide into the sleeve? My rods are 1004924 M91 and 1004925 M91 for inner & outer respectively. The 925 rods slide into an intermediate sleeve 1004928 M91 and are retained by a pointed set screw & lock nut. The shaft on the 925 rods is 3/4" OD. I will take the steering arms to the machine shop for the tapered bore. My plan is to reinforce the wedge holes with some donuts cut from a piece of 4" sch. 40 pipe (4.5" OD, ~4" ID) to help secure the axle extensions.

You've get it under control. Only variation is on
the 3/8" set screw, of the intermediate assembly;
the assembly requires a quarter turn, to permit the set screw to match the F40 rod grooves. This
should be tolerable, to most, or you can machine
your custom grooves. You may have to polish the
rods up, even freeze them, if tight, but unless
new is now of China origin, they 'were' a 'fit'.
My use of 'were', meaning as recent as last year.
Good luck.
