HIGH WATER -- (HIGH WATER-2)
My Amphib index
I had plans to put the vehicle on fire.
But I decided that this event would be incomplete
without the presence of the professional mechanic that has build this vehicle.
Chained on top of it I mean!
In the light of things below on this page.
I think those feelings will NEVER fade away.
|On High water part one I have mentioned
the reverse cooling system.
and the fact that the first test drive went to hell and back again.
|While working on the fuel and the oil
cooling system I found that the hoses used where water hoses
NOT to be used for diesel and motor oil.
|If you use them for motor oil or diesel they will get HARD, very
On the right is a photo of a diesel fuel hose, NO trick shot, it is a 2 kg hammer on a 12 mm "soft" rubber hose.
So the fuel leak was the vibration of the tanks (pressure variations in the fuel)
and two hoses that would not bent, fastened with a very cheap plastic hose clamp.
I was removing the old hard hoses and trying to find a way to
the hoses rubbing again to clamps, walls, engine or to other
I suddenly saw it, but not the light.
The oil temperature was measured AFTER the oil cooling system, so when I thought the oil temperature was a 140 degrees the temperature was in reality 160 to 180 degrees.
An image of a person with an axe in his head came to my mind.
This brought back memories of the engine bay temperature meter
measured the temperature of the fire wall.
I used it now to measure the cool water temperature, before and also after the cooling system. By the flick of a switch I can see what there is left on cooling capacity.
That gives me a fair idea when the overheating starts.
I'm going use the same system for the oil temperature.
|One of "those" other things:
The builder used old cracked rubber O-rings
and old copper rings.
The O-rings came out almost broken.
Not much of a leak but still a leak.
I have to look into cooper rings and/or O rings of the right size and quality.
The old hose reads hydro 16 bar that is a water hose, a hydraulic
hose has 200 bar written on it side.
If I try to bend them sharp they will crack
The new one reads Petrol - Oil 25 bar
and it is nice soft rubber that will easy bend.
I DO NOT HAVE
40 years experience in building cars.
but this I know:
Oil and cheap hoses do not go together.
|In the mean time I have to rethink the cooling system, I know now the real oil temperature is 40 degrees higher than the meter showed.|
|Work was stopped on Nemesis
between February 2008 and July 2010
I was not in shape to do anything.
