Trouble removing bolts to rebuild pump- motors

[valley ranch]

My hot tub is down ~ the motor I have (Hayward) has one long bolt that so far acts like it will break rather than come out ```

Your opinion ~ can the motor be held together well ~ with only the three bolts ~ after replacing bearings?

I have another Max Flo ~ with the same problem on an other bolt```

Thanks Richard

I gut says no Have you tried PB-Blaster? Heat and tapping? Those are out go to for stuff like this.

The bolts holding the pump to the motor are probably a low grade , plus my guess is they aren’t a large diameter - translation: they could shear off easily. If you haven’t stripped the head and broken one off, I would start with penetrating fluid like Kim suggested. Kroil is another brand that works well. Can you safely put heat on the bolt with a propane torch? I am not sure what the housing is like. Be careful not to damage seals, etc from heat. I would soak it a few times over a few days to see if that would help break the corrosion

Hi ~ Excuse my ~ delay in coming back ~ been in a mass of things to do ```

Kim ~ todd ```` I tapped ~ I even drilled down to just in front of the nut and applied ~WD40 ~~~ not the nut spins in the plastic ```

I'll see if I can separate the pump from the motor & grip the nut ~ and come back with the good news ```

Can you post a pic or two? When Kim said tap , I was thinking drill the screw and use an upsized tap to cut new threads.

I think she may have meant tappy tap tap with a hammer.

You lost me at drilling in front and applying WD-40. That stuff is better suited to cologne than a rust penetrant but if it’s better than nada.

oh man, I don't envy that.

I've read threads like this before.

When I needed to replace a leaking pump seal 2 years ago, I put a little dab of anti-seize compound on
the motor bolt threads and hope that will never happen.

I did mean tap with a hammer as the heat and PB Blaster would work together to get things moving. The hammer taps helps get the things loose as well.

13lb pursuasion generator will make quick work of everything around the bolt

I’m all too familiar with the Fabulous Blaster. That’s good stuff

If the female thread in the housing is spinning with the bolt- your housing is shot.
