    Runn and Start Capacitors for Doerr 5HP 1740 RPM motor... Nidec bought Emerson which had bought Grainger which had bought Doerr everyone says buy new

    Put a 30 uf in and check the draw you'll probably be done. 30 is very common in 5hp 230v 20ish amp compressor motors replaced lots of em. eKretz do you remember what you ended up with? ALso don't worry about the lowest current just get it to the rated fla.

    Is Monel suitable as a thrust wear surface?

    Good point about the copper I don't know why that didn't occur to me. maybe it doesn't matter but that's enough of a reason not to use it. I will just make a small order for something.

    Is Monel suitable as a thrust wear surface?

    Actually I haven't decided that is why I asked if anyone knows if it would be a good surface for the 954 bronze. I'd like to use in stock material if I can if not I'd much rather order something than experiment. That said it's a bit of an experiment in areas as in 1911 the engineers were still...

    Is Monel suitable as a thrust wear surface?

    I am working on repairing a damaged thrust surface on the back of an engine block this surface takes the thrust pressure when the clutch is depressed. The rest of the time loads are minimal as the trans has straight-cut gears and the crankshaft has its own thrust control. The original system...

    Can I substitute different DP gear cutters?

    So I put the gear on a rod spun it slow in the lathe heated it to nonmagnetic quenched it in 120-degree canola oil and it got harder than a 50 file would cut so I drew it back in the furnace just to where the 50 file would just cut and pulled it. checked distortion with blueing and it's good to...

    Can I substitute different DP gear cutters?

    Thanks, Ken this gear is only in mesh for reverse so pretty low use and rpm. I will look into induction I may have a coil that will fit over this gear I just need to read up on induction treating 4140.

    OT - Is there any place to have a radiator made?

    I doubt you would want or need to ship it out here but Radiator Supply House in sweet home Oregon does this all the time for me on luxury motor coach radiators that are NLA. They can work from prints if needed but surly someone closer can do it for you. At any rate this is still done often...

    Can I substitute different DP gear cutters?

    Just wanted to update the thread and thank all that replied for the help. I was able to find a new cutter for less than the $300.00 I had originally found. Cut the gear as Dan suggested and it came out perfect. The next question is should I heat treat it? Keep in mind it is in use only in...

    Can I substitute different DP gear cutters?

    Yes, the depth is very near.225" so I assume that an 8dp cutter is still used and depth adjusted to a stub profile? I also assume this was done to prevent tooth interference with the much higher tooth count mating gear. This is all starting to make sense the gear doesn't measure to be as worn in...

    Can I substitute different DP gear cutters?

    Thanks Guys, Dan your pm box is full. A 20degree gear gage seems to fit well compared to a 14.5 but maybe other factors influence that? I have a copy of an original document that seems to suggest 20 but I may not be deciphering that correctly I will post it here. I can't seem to get the pic to...

    Can I substitute different DP gear cutters?

    This could be an option as the blank is 4140. I may be overthinking this and worried about nothing I just need to cut the thing and see what I can make happen it's a small blank so if it goes south it's not a big cost. We have more 4140. Gears are just one of those things that I'm never sure of...

    Can I substitute different DP gear cutters?

    Hello A question for those who know gear cutting. I rarely cut gears. I need to make one gear that is 12 tooth 8DP 20degree PA. That cutter is a little hard to come by and expensive when I do find it. Even then two places emailed back to inform me they don't actually have it. This gear is for...
