................. just maybe.
Jabsco Heads. I don't think I'm telling any tales out of school when I say what a load of crap they are.
Only thing that's kept me from replacing mine with a respectable head is that the step where it's mounted appears to be made for a Jabsco with 1/2" clearance on either side of the base. Looks like I'm doomed to be stuck with this thing until the end of time.
In all fairness to Jabsco, I must say that when the head (specifically the pump) works, it works well. Problem is that the piston lubrication only lasts about a year. It then becomes a grueling bicep and tricep workout each time you pump out the head. Peggy had recommended Super Lube a number of years ago and although it is highly water resistant, one year is still the limit.
Lubricating the pump piston is always an exercise in frustration. Water coming off the top of the piston and WORSE hanging off the bottom. Always down the front of my shorts to. Not my idea of fun even when drunk.
This pump is not made for disassembly and assembly. Actually, it's just not made to be maintained. After a few disassemble/assemble cycles, the screw holes weaken and the required force to seal the gasket disappears. That along with the limited patience I had when I started the job. Reverse turning the screws until that starting "click" sounds does help but only for a few times.
Now, having collected an extensive assortment of Jabsco pump parts over the years, I thought I would see if I could cobble something together which might improve this monument to over-consumption. Essentially, if I could keep this thing lubricated, it might just last a little longer...... maybe. As it's thrown together in the factory, the pump has a shaft with a single piston on it. Unfortunately, this is the one thing I don't have a picture of here. The grease is all too soon wiped off the piston ring and the pump becomes a bear to pump.
In order to store grease near the piston ring, I installed two piston rings to hold grease. Room for the extra piston was made by adding an additional 1/2" of thread on the rod.
This formed a 1/16" deep cavity to store the grease.
Three years ago, the above assembly was heavily greased and slipped into the pump cylinder. It was only at the beginning of this summer that it needed another lube job.
I'm hoping for another three years until the next lube job.
