Water Tank Cap Remover
I have a bit of a problem at times, undoing the water tank filling caps.
Sometimes it’s ok but when the caps, or my hands are wet, I have trouble turning them on or off. So this is for those with a touch of arthritis in their hands, to make your life easier. Or if you are just plain weak like I must be.
When independently camped, these things have to be opened more than one would think, so I have made a pair of pliers up just for the job.
I cut down an old pair of pliers, as the opening has to be about 15 mm to get a firm grip on the cap. Then just welded the tong parts, and we are ready for action. It doesn’t look pretty but it sure makes getting the caps off easy.
The pliers have a single tong on one side and a double on the other.They get a good grip, and make it easy. Also it is required to push in and turn simultaneously .

Re: Water Tank Cap Remover
This shows the pliers, and that the tip of the pliers was cut off prior to welding on the tongs. Stainless steel is easy to ark weld and very strong.

Into the inner sanctum; and there are all the top secret inventions.
To hang a pair of pliers just cut a couple of ally tubes ( an old roller handle) at it at an angle and then pop rivet it on. Try it out for position before drilling.
The list on the wall is my departure check list.
The jockey wheel holder has a tapered plate with a fold each side and just slides up to remove the whole thing. Not seen but the actual wheel is trapped in a small frame to stop movement.

Re: Water Tank Cap Remover
I did an update due to photobucket stopping pics. These tank caps get a bit slippery when wet. This makes for easy removal.
Just weld a couple of tabs onto an old pair of pliers and shape to suite your tank cap.

Well done.

Re: Water Tank Cap Remover
Great ideas Paul, and Kudos. By the way “Happy Birthday” for today!
For those without unlimited spare pliers and welding skills, a more simple idea is to use a short length of flat aluminium bar and drill some suitable holes in it to put some small (say M6 x 50) bolts though and lock nut them to the bar. The bolt ends will go into the indentations on the filler cap and just use the bar to undo. You would put a small bend in the flat bar so your knuckles don’t get scraped on the van wall.
If anyone has seen a 44 gallon drum cap unscrewed you will get the idea.

Re: Water Tank Cap Remover
Perfect analogy

I used my drum tool yesterday. I get sick of filling 20 Lt drums with petrol so I took my 44 (200 Lt) drum laid down and chained in my old Hilux to the nearest servo hoping to fill it without being turfed out.
Many servos don’t like one filling their 20 Lt drums unless placed on the ground to minimise static electricity sparks. They can switch off the pump if they spot you doing the wrong thing.
With my 200 Lt drums I have always carried and used an earth cable to connect the nozzle to the drum before starting. Gone are those days that I would take 3 x 44s standing up in the back of the Hilux. That was pretty obvious at the servo. OH&S has killed that for me despite my earthing procedure. Perhaps it is just not a good look to other customers
