macerator pumps, Liberty Coach

[dalej]

My masorator pump quit working so I called the company and they said not to run it dry so I replaced the impeller (it was chewed up) and put a on/off switch right by the masorator pump that way when I open the black tank valve I can run the masorator pump and shut if off after the gray in empty.

The way mine was set up the switch was at the dash and when the pump was done pumping, I went to the dash and shut it off.

Geoff, did you get your pump issue resolved. Yours looks to be the same as mine, a Jabsco 18590.
The Mfgr's. brochure states that after a sustained period of disuse the impeller may become stuck in the pump housing.
They provide for the shaft to extend out of the motor with a screw driver slot in the end. Turn it a couple times in a clockwise direction when looking at the slotted end. Yours looks to be pointing out, so it should be easy for you. (good engineering and design Marathon)

My pump is at arms length in a tight space over my tank with the shaft pointing away from any access. (bad design and engineering on Liberty's part)

I have an idea for a tool that should be able to turn my pump, but I need a couple dimensions.

What is the diameter of the slotted shaft and how wide is the slot?

If anyone else can come up with the dimensions I would appreciate it!

Thanks, JIM

Jimmy C,

I thought your pump ran, but like mine, won't pick-up a prime probably due to a bad impeller!

[JIM CHALOUPKA]

Tom, I can not feel any vibrations of it running and I can not hear it run. So I'm assuming it's not running. That's as far as I have gotten with it for now.

I can't turn the shaft with my fingers I can't "rab" it.

If I knew the dimensions I asked for I could cross drill a nut so it would fit the shaft and leaving the drill bit in the nut to engage the slot, I think I could rotate the shaft with my finger tips. As you know it is barely assessable in its location.

I won't comment on your spelling Jim, but will comment on the remark about it not making a noise.

Have you verified you have power to it?

When it gets power, even if it has lost the prime, the macerator on mine makes a very loud noise. Start with the basics before you start considering the more complex stuff, And if it is getting power, just reach in there and remove it so you can work on it at your workbench. When you reinstall it nothing says it has to be returned to that exact location.
