I have been considering filling in the gear on the mainshaft of my 242 (They are the spiral cut gears). I would be filling them with TIG and turning it all down smooth.
All the breaks that I have seen have been on this spiral geared section. The base of the splines is a smaller diameter than the rest of the shaft and this seems to be the weak point in it.
Will the heat from the TIG weaken the hardened shaft, or will the change be negligible due to the filling? Is there much chance of crystallization? Of course the shaft would be pre-heated and post heated to 550 degrees in the oven.
It should go without saying, but this is not my DD and I don't need the speedo. So save the "You won't have a speedo anymore" comments.
