The Only Burke #2 On The Interwebs

[Cooter Brown]

I bought this machine on eBay in Ohio early 2017 for $350. It has the biggest 2HP 3PH motor I have ever seen, the motor runs great but I can't get it to run slower than 1400 RPM, the pin spanner nuts on the spindle and the clutch won't turn. So I can't get the machine to run slowly enough to run high speed steel tooling.

Does anyone have any ideas for removing those pin spanner nuts?

Thank you

Soak the pin spanner nuts a week in PG Blaster. insert pin wrench, rap quickly with a dead blow hammer until they turn.

I'll have to give it a try

A bit of heat from a propane torch might help also- and tapping around the nuts with a brass drift or hammer-cautiously

None of that works. I'm thinking of making a spanner wrench that goes on an impact gun.

Assuming the problem is corrosion, I have run into situations where PB Blaster (my preferred loose juice) won't get it done. In all of these cases (so far...) a homebrew of 50/50 Automatic Transmission Fluid and Acetone has worked wonders. Soak it good, let it sit, repeat two or three times over 24 hours and then some vibration/impact may do the trick.

If you have a wrench that fits them you could try this tip from AvE.
He cuts off an impact hammer chisel and grooves it to use on the side of a wrench.

Please keep us updated of how it's going!

I have all the penetrating oils, but after a lot of frozen stuff, my go to choices for tough jobs are 50/50 atf/acetone, and Kroil.

I'm almost just thinking about giving up on the pulley swap and just getting a VFD it's only a 2HP motor, about $250 VFD.

I have tried all of that but I cant get anything other than motor nut to turn...
