quote PM T2:

Wouldn’t be too hard to save the original driveshaft if you spliced a new piece on the end and cut the splines in a mill.

Since Bill Andrulitis taught me how to properly cut splines without specialized tooling, I’ve done it several times… a few of them even fit, actually

Best,

I wish I knew how to do that, it would be a great skill to have. I have extended drive shafts by cutting, center drill, add a length of drill rod and fill with weld. Turn on a lathe and they work great. The shaft needs to be the same diameter to get the pump on, so I like the weld repair method. As for this repair that Mumbles has, this is kind of neat. I have an old TN that Kevin was assembling from parts that the splines in the crank are wiped out. Not a bad idea for something that is really scrap otherwise.
