Maybe it is the bearing for your belt tensioner? This has a spring loaded tensioner for the serpentine belt, right?

Jan, it isn’t too hard to pull the fan-belt off. Then you can spin, wiggle all the pullys and listen for your noise as they spin. TomC.

On my Dodge Dakota the bearings went bad on my belt tensioner, started grinding making noise the belt came off. New parts needed tensioner, and a belt. No fun that day. When it started to make noises I should investigated it more.

I have removed the belt, and spun all the wheels, and find nothing that sounds, well the generator sounds a bit, it is a spring loaded tensioner, I changed the belt and both wheels a few months ago.
But if it’s the water pump, I’ve never heard a ball bearing in a water pump sound before it leaks water, have you?

That happens sometimes, a cheap or bad bearing, the seal can handle it until the bearing gets to “loose”, wich often happens fast.

It must be the water pump, took it out this morning and the bearing is very loose.

Since you have the pump out, go ahead and change all the coolant with a water rinse. When coolant gets old it loses its lubricants that help the water pump.

That was probably a good idea, thanks Cody

If I get a leak at the cyclone, is it so hot then that the gas will burn?

I would think so, maybe. I’m not sure what the auto ignition temperature is when oxygen is introduced.

Even without reaching auto ignition temp, flying sparks will most likely make the gas burn anyway.

How should incoming pipes get in, or look like, so as not to whirl up soot from the bottom?

Jan, if it’s a wet media filter I don’t think it matters much as long as it’s as far away from the outlet as possible. Gas will always choose the easiest path anyway.
On my pickup gas enters a small upside down bucket with holes in it like a Swizz cheese. On the Volvo gas enters straight from the condensation tank below. The inlet will create its own void if it’s too blocked with soot.

When I have this shutdown, will the after condensation spread to the filter then?

Jan, you run a hot fabric filter now, right?
Listen to one of Niklas’ latest videos. The guy with a gray 142 mentioned something about closing off the woodgas line at shutdown for condensation reasons.

No, no hot filter yet, trying to understand if the moisture can move when I have this shutdown, or if I need to put on another valve.

Hi Jan, i never close-of the filter from the gasifier when shut-down, but i have open primary air inlet, (no shut-off valve) so most of the after-gasses go that way.
And my filter is very big, and double-walled, in the soot-collection at bottom i’ve found only traces of moisture under the double wall.
Anyways i think it should be a good idea to close-of the filter at shut-down, safe and “bulletproof”
Edit: sorry, i thought you had installed a hot filter.

When I stop, I remove the gas supply pipe from the filter and let the engine use the gas from the filter and burn the resulting gas, I think it is good if the steam from the upper part of the gasifier suffocates the glow zone and cools the gasifier fairly quickly.

That will save you fuel/charcoal.

Thank you Göran, you have drive with a hot filter, and have experience of this.
I have made a filter and am working on nr2, but the older I get, the more insecure I become, I am very unsure if I will get my first filter tight
