Tedious and time consuming, but almost done. I'm just waiting on a replacement steering column tube that I will have to cut to length and weld the throttle lever mount to. The steering box sector shaft seal should be here any day now, also. I had to replace the steering box ball bearings and reshim the steering shaft assembly. I replaced the steering wheel, acorn nut, upper steering tube bearing, spring, spring washer,tube cap, and the lower tube clamp. Unfortunately the cast steering box cover was cracked in three places around the sector shaft adjusting screw. I didn't notice this until I sand blasted it. Luckily I had the exact cover in nice shape on another Ross steering box. The ball bearings had some pits in some of them as you can see in the one picture, but the races were fine. I'm going to continue cleaning the rear end and brake parts while I wait on replacement parts to arrive.

   Nice job!!!!  That looks exactly like the steering setup on my bf avery V.  Probably is--  they are from the same era.

Thanks Pete. It's the same exact set up as in my '56 Power King, also. The Mighty Mites have the same set up, but the box cover is steel and not cast and prone to cracks, from either water freezing in them or over tightening the sector shaft adjustment screw.

Well, the replacement steering column tube came in and I already knew that I had to shorten it. The paint job was terrible on the tube, but I planned on removing it since I had to modify the tube anyway.The other problem was that the inside diameter of the tube was .030 too small at both ends. After some time with sophisticated machine shop tools, yea right...I made the tube the same as the original.I had to make a new slot at the bottom of the tube since I had to cut a few inches off of the tube. I have to weld the throttle bracket on, and weld up an extra hole that was drilled in the bracket. I just have to clean everything one more time before assembling everything, then the assembly will be ready for primer and paint. In the one picture of the parts, I laid out all of the parts that are junk and had to be replaced.

Dang Jim ! that looks like new !

 

Tools of the trade man, I prefer that over the high tech, more rewarding for sure.

Thanks Jess, those old files still cut like the day they were made. I like hitting yard sales for old tools, and I find some good stuff for cheap. The steering column restore was fun, but it took some hours to do. I got the throttle bracket welded on and it's just about ready for paint. I have to make a new U-boat to mount it when the tractor frame is ready

Actually my buddy welded the bracket on with a stick welder. I've only used a wire feed welder and probably would have put the welding rod through the column, HA! I need to spend some time with a stick welder on some junk steel.
The tractor has a looooong way to go before it's finished. I'm waiting on parts for the transmission, but I have everything needed for the rear end. I'm going to continue working on the rear and transmission until they are done. The engine is completely shot. The crank rod journal is .005 beyond reject specs, the wrist pin is loose in the piston and rod, the cam lobes are rounded on the edges, and the tappets are badly dished. So far, I picked up an NOS crank, a gasket set, valves, and I already had an NOS rod and an NOS .020 piston. I'll pick up the rest of the parts and start a new thread with the engine overhaul. It's a gear reduction Briggs 23 R6d from 1956 and original to the tractor. I'm planning on picking up a Lisle cylinder hone so I can hone the block .020 over. The block will get new valve guide bushings and the valve seats cut. I'm looking forward to the rebuild!
