Doctorbill recently brought up a subject which I swore I would not get into as I'm still in therapy trying to heal the mental scars.
Recently had my Jabsco macerator develop a leak at the gasket. Damned thing was replaced four years ago. This brings to mind a post dealing with EXACTLY the same thing which I had always meant to check .......... but didn't. Lucky number 13 stud.
While removing the macerator, I found one of the long studs (surprise - part #13 in the drawing) laying in the compartment below it. My first thought was that it'd failed from corrosion. Now, I've suffered through enough painful memories in a career I'd rather forget to know this failure was mechanical in nature and not corrosive. Bloody crap .
Off to WM, put my hands over my head, and a guy with a mask takes my wallet. He then gives me a replacement Jabsco pump ($224.99) and my empty wallet. I leave penniless but unhurt.
Get to the boat and had to rotate the new pump oulet 180 degrees to fit the application. Undid the studs (part #13) one, two, and three. The fourth stud starts to come out and then suddenly releases. Interesting. The stud snapped as a result of simply removing it. New Jabsco pump, same assembler, four years later, still over torquing the lucky #13 studs . Still can't afford to buy a torque wrench.
Notice that the Jabsco drawing lists only two studs (part #13)when there are actually four.
Back to WM, put my hands up, same guy with the mask takes my wallet and we talk. I say "#*$&*$^+@!" he says Jabsco macerators are crap. He recommends a Johnson pump at $184.99 or a West Marine pump at $174.99. The WM pump is made by Johnson. I take the WM pump and leave, lucky to get away with the clothes on my back..
Had to rotate the outlet 180 deg. on the Johnson macerator so took off the cutter and rotated the discharge. Nice looking components on this one, SS studs, nice bronze cutter. Looks good except for maybe one thing .............. which way does the shaft rotate ? ? ? The cutter has a clockwise thread and no lock nut on the shaft. Better check the rotation. Touched the leads to the battery and the motor leaps into the air and tries to smack me. Starting torque up the wazoo ............ and it's clockwise rotation. Not good .
Great, with the crazy torque, the inertia of the cutter, and the resistance of the sewage, bound to lose the cutter in very short order. And, it'll drop down through the suction head, never to be found in the suction sewage pipe. No mention in the assembly instructions about losing the cutter so slap on the blue Loctite and hope for the best.
The pump goes in and I check myself into a treatment centre from where this was written.
