Well, I have the new .8 screws. Let's see if I can find a M5x0.9 die. Thanks for the tip.48lesco wrote:Another thought, most tap and die sets have both the M5x.8 and M5x.9 die for some reason, and I have successfully "converted" new .8 pitch screws to .9. As OldStan said, not much stress on that part either way. This way though, you don't modify an original part and I'm not sure if that's important.

You have probably already figured this out, but it's going to be hard to turn the phillips head screw into the die. I used a phillips bit chucked in a drill press with the die clamped in a vice. Steady pressure on the bit and turn it by hand. You might be able to do it without the drill press, I didn't try.
Put the die in a bench vise, turn the screw in with a magnetic driver.48lesco wrote:You have probably already figured this out, but it's going to be hard to turn the phillips head screw into the die.

As I know it it is much easier to turn a tap in the part on the stator than to turn a screw in the die.
I do this with every engine I restore now. .................lm

Not ruining anything. I am rethreading a new M5x0.8 screw to 0.9 pitch, to fit the alternator cover.48lesco wrote:Well, the cat's out of the bag now... Why would you ruin an expensive, perfectly good 50-year-old vintage part instead of a 29-cent screw??????? You young fellas are always looking for an easier, quicker, cheaper way.
