Dirt_Floor_Poor Posted February 5, 2022 Share Posted February 5, 2022 This has to be the first new undercarriage parts for a T-6 that have been manufactured in a long time. 2 Quote Link to comment Share on other sites More sharing options...

We could, but they are simple enough and will come out quickly on the old manual lathe and mill the museum has…only time is needed to do this there, no other expenses. 2 Quote Link to comment Share on other sites More sharing options...

What alloy will you use. Do you have your own heat treat capability. Those deep lube holes in the end will be the pain in an engine lathe. We deep drilled many tons of pins in Warner Swasey turret lathes. You can't beat them for heavy stock removal also. They are cheap to pick up in this era of CNC . You know one would make a nice museum piece ......truly a landmark of industrial history. I hate to think how many have died an undignified death. 1 Quote Link to comment Share on other sites More sharing options...

We discussed this for a while. The metal will be a high grade steel. We could harden them, but we debated how much will it be used. It will never work every day again. It will maybe pull a small plow once a year. More likely less than that even. It will get driven 2-3 hours a year at most. None of us alive today will never need to replace them. The machining does not worry the machinist at all and he will have no trouble making these. He has made considerably tougher items in the past. He was originally planning on just grinding them...but when we started looking we realized how far he would have to go and the amount they would need to be ground (some of them we debated may even go smaller that the bushings we just put in), on top of having bad seal surfaces, it would be more efficient to make new ones. I am sure he will debate himself about the hardening in the process as he mentioned some of his options including nitrogen hardening them if he decides it is necessary. That is the next step...we will see where it goes. 1 1 Quote Link to comment Share on other sites More sharing options...
Rawleigh99 Posted February 7, 2022 Share Posted February 7, 2022 Get surface hardened ground stock of the right major diameter and machine with carbide tooling. Once you get the rind off they should machine easily. 1 Quote Link to comment Share on other sites More sharing options...
just Dave Posted February 7, 2022 Share Posted February 7, 2022 I have marveled at the quality of material and heat treat involved in my old IH tractors.... You as restorers have done amazing work on this machine with the prep and restoration of worn metal. You owe it to your selves to put a hard shaft in the rollers. Even a case hardening or a carburizing would be well worth while. On 2/5/2022 at 4:44 PM, Mogulman said: The machining does not worry the machinist at all and he will have no trouble making these.

Rawleigh99 Posted February 7, 2022 Share Posted February 7, 2022 You would need someone that did spray welding to save the originals. 2 Quote Link to comment Share on other sites More sharing options...
rusty iron Posted February 8, 2022 Share Posted February 8, 2022 Dont the original shafts have an oil cavity in the centre? Quote Link to comment Share on other sites More sharing options...
just Dave Posted February 9, 2022 Share Posted February 9, 2022 They are deep drilled from one end and cross drilled in two places . Spray weld /metalizing is big cost , it would require removing about a 1//4 off the diameter for prep. If they are the typical IH quality heat treated alloy that would be slow and hard on expensive lathe tooling. On a stubby shaft like that you could get by with 1045 and case hardening. If it was my tractor it would not look nearly as fabulous these men have done but it would not have soft feet.....I would take the existing shafts down to smooth via OD Grinder and make my bushings fit. I would accept some small pitting to remain of stock removal exceeded .100" per side. You could remove the stock with ceramic inserts but they are pricey. We will see how you do it I'm sure, Hat's of to your project. Dave 1 Quote Link to comment Share on other sites More sharing options...

All the other parts rebuilt in house. Parts are checked carefully and only rebuilt as necessary. Some NOS parts, always the best we can find. So far so good! 1 Quote Link to comment Share on other sites More sharing options...

Mogulman Posted July 16, 2022 Author Share Posted July 16, 2022 Checking over the dash and electrical components to make sure there are no extra holes where they shouldn’t be. Waiting for the pistons and rods to come back from the engine shop since we needed new bushings. 5 Quote Link to comment Share on other sites More sharing options...
