Engines / Re: Electromotive Series of Metals and your Engine
« on: May 31, 2020, 01:19:25 AM »
Engines laid up for many years, connecting rod bearings are made from an alloy which contains tin, on our list Ti is more reactive than iron so over time connecting rod bearings will react to galvanic corrosion.

Roller and ball bearings and their races contain chromium which reacts with iron, aluminum pistons are way above in the list and the most reactive metal in your engine.

If you have a bit of scrap aluminum kicking about take some sandpaper and make a small area shiny clean. Within hours the cleaned spot will have acquired a thin layer called a passive layer.

The passive layer is kind of self healing, drill a hole or scratch aluminum the passive layer soon appears.

We've all seen how aluminum corrodes as it ages when a steel fastener has been used to bolt two pieces of aluminum together, looks like rot.

Engines / Electromotive Series of Metals and your Engine
« on: May 31, 2020, 12:48:55 AM »
A boat used in salt water will use a sacrificial zinc anode to protect the metal parts from premature corrosion.

Boats berthing at a marina should use a "shore power isolation transformer" while connected to shore power otherwise any boat in the marina with poor or non existent anodes connected to shore power will suck the life from your boat via electrolysis.

Boats used in fresh water use either a sacrificial aluminum or magnesium anode, the domestic hot water tank in your home will also have either type of anode factory installed.

Sacrificial anodes should be checked periodically and replaced as required. And this goes for those of you using heat from your engine to heat water for domestic or other use.

Install the appropriate anode it will add years of life to your engine. Liquid cooled engines often suffer from cylinder liner porosity caused from electrolysis, inhibitor's added to coolant can slow the process.

The list below, the electromotive series of metals, as a precious metals refiner the list is of importance to me.

For instance if I had a multi species liquor and only wanted the precious metals recovered from it then I would use scrap copper. All the metals above copper would be unaffected and remain in solution. Bla Bla Bla.

Each metal on the list above another reacts with all those below it and none above it, having basic knowledge of the series will help you understand galvanic corrosion and how to prevent it.

What do you use the chemicals for?

There's enough $$$ in that vision ware pot to buy me a couple of Lister's

Ms. Hoke explains in great detail.

Stripping the aqua regia solution of values. In the spent aqua regia solution from your parting operation, there are several values in ionic form, including some platinum and perhaps a bit of iridium.

The solution will be a brownish colour unless there is considerable copper and nickel as base metals in the batch, in which case it will be green or blue-green.

I know I asked what was a silly question about the chemicals and got the replies expected. It is interesting what people do with different chemicals and is why I asked. I go through a bit of liquid pool chlorine in the cleaning work I do.

The chemicals are used to refine precious metals most of what I know about metallurgy came from Hokes Refining Precious Metals Wastes.

The digital copy of the book is  free download from https://www.scribd.com

Yesterday I reacted Hydrochloric acid with a household ammonia cleaner to make ammonium chloride a totally new chemical with many uses.

Ammonium chloride is what makes the unique flavor in Black Licorice, it's used in certain baked goods to add crispness, also used to add patina to copper, used as a soldering flux.

The ammonium chloride is inexpensive to purchase however quality is questionable. And I need a chemically pure product.

To make it chemically pure the ammonia chloride crystals will be re-hydrated then once again the liquid evaporated then cooled to allow the crystals to reform any liquids left over discarded. The procedure is carried out twice more.

Ammonium chloride is then used to precipitate platinum from a multi species liquor containing nickle, platinum, palladium, rhodium with perhaps a bit of gold ions in solution.

There's more than one way to skin a cat, ammonium chloride is one of many reagents selective to platinum.

Apparently no serious harm came to the SR2 Lister, below a snippet from an email received this morning from Taylor.

My invertor is happy with the power it produces and charges my batteries too. Probably ran it for 8 hours so far and it hasn't burnt a half tank of fuel.

Today Taylor told me he got 13 hours run time from the two imperial gallon fuel tank, and that his propane generator uses 2.5 litres an hour.

He also mentioned many of his friends ask WTF is that when they first see the odd looking English diesel.

Even though the generator is the Start-O- Matic, Taylor loves starting the engine using the hand crank to keep his friends buzzed.

Now that Taylor has had a taste of Lister he's totally hooked, that old generator went to the right home.

Remove the cotter pins from each clevis, then move each rack, if one or both fuel pumps are seized it will show up immediately. It's my guess the problem is circled in red.

Remove cotter and clevis nearest the red circle, I think the rack is going to move once disconnected.

The sliding bar that co-joins the fuel injector pumps operates the fuel rack, are you able to move it back and forth and what position is it at while trying to start the engine.

With the fuel rack all the way to the left, no fuel will make it to the injectors.

Compressed air is not high enough pressure to left the injector needle, google pop tester then watch one of the many youtube videos available.

You have a Lister LD2, often used in marine application. From the flywheel end your engine is clockwise rotation.

Crank handle operates from camshaft extension - counterclockwise.

Looking at the state of that bolt/follower - I'd say something let go in that gearbox under full power/rpms. I suspect there's a lot more damage in there to find...

Roller for the shift detente that holds the transmission in either forward, neutral or reverse.

What I needed to know was in the Basler AVR doc.

This is the generator that i picked up in Ontario, first time use the voltage meter on the control panel shows 250 volts.

I'm stumped why there's no power beyond the voltage meter, the breaker checked out.

I'm considering picking it up and building it into a prime mover.

Make sure before you buy it they have the other missing flywheel.     ;D ;D ;D

The shaft your looking at is the accessory drive on the camshaft, turns in the opposite rotation at hakf the engine rpm's

Aloha glort,

Very troubling video.  I guess China had the only realistic solution so far and they've moved back from that.

It's just a tad prejudicial.  Like the last part about earth day.  25 panels putting out 1200 watts?  really?  I'm not throwing my panels away.  They still save me thousands of dollars every year and I'm burdened with the 250 watt cutting edge units of ten years ago.  Stiil; Five would put out as much energy as their array would according to the film. 

I did learn that biomass just isn't what I thought it was.  Burning wood only works well where there's a couple of people every few miles.

Perhaps dying in bed in the next couple of decades isn't so bad after all or not as bad as an orangutan death somewhere.

I would like all videos to have a visual date stamp in the lower right corner.

Snowman18:  I realize selective and willful ignorance are an important part of the foundation for fundamentalist thinking but I think this film just might fit your profile.  Al Gore is not a hero in this film.  Corporate Capitalism is not the light to sustainable life on Earth. 

Maybe Soylent Green isn't as crazy as it looks.  I see mass sterilizations in the human race future.

What's your take glort?  (Play nice and more people will try to read your encyclopedic contribution.)

LowGear your a lucky man because you can do something I can't do, you can kiss my ass and I can't.
