Well, I got the first batch of new axle's and sprockets from my machinist today. He does such fabulous work! I envy all of you who have machining skills (and carpentry, paint, electric, small engine....etc - the list goes on and on!) Anyway, they were made to the specs that Whipper suggested (thanks Whipper): 4140 pre-heat treated TGP. Spocket tubes are all 1/2 " wall thickness. Flame hardened sprockets. I went with shear pins instead of woodruff keys, but he put in grooves for snap rings just to keep the sprocket in place in case of a catostrophic failure at high RPM's. This should save me from blasting a hole through my floor.
Everything is perfect except for one big detail. The rims that arrived yesterday from Recreatives are 6" inside diameter...my wheel hub flages are 7". Gonna have to have them turned down 1/2"! Otherwise, I would have had a rolling chassis by the end of the weekend. dang
cleaning up the yard today to make the wife happy. Had an opportunity to take this video of the differences between early model and late model Terra Tiger chain guards.
Looks great! I have an old Terra Tiger that I am about to begin on. How did you make a reverse? It seems to be electric by the sound......
Also, I saw the Millington Flood videos/photos....Did you go there to help out? I did as well. We re-did a house that flooded for a couple of widowed ladies. It was through my church and a local Millington church as well.
The bottom end of my Terra Tiger is all new, but the axles are binding in the center bronze bushings. Since everything is new, will the axle's eventually work themselves "true" once I apply power to the wheels and drive it around a bit?
I would put a plate between the two angle iron braces, under the center bearing assy, and weld it in. It would help fill the gap under your bearing and tie your braces together for strength. That center bearing is a bad design because the axles MUST be in alignment. Alot of bearings are rounded on the outside allowing for misallignment.
This is what they should have used. PillowBlock.jpg
Actually, I tried to outsmart the Allis Chalmers engineers and did just what you are describing....but my problem is that the bearing is too high, not too low. I am going to put the wheels on today and see if that doesn't help....I will post a picture of my custom center support later tonight.
And here is some video of the problem I have with the center axle bearing. I need to get it lower, but aside from spacers under the frame supports, I cant think of any other way to accomplish it. Unless someone here tells me that the bow is not significant enough to worry about....I just want to make sure I get it right the first time.
