That's the "official" story, however the timing and the frank admission on his website that he had a load of sandy engines were too coincidental for some skeptics.

Ok, so let's take a gulp of air in the same cylinder, compress it 17 times, then inject some organic substance, say, #2 diesel and measure the pressure that results, then calculate the force on the cylinder, head and piston.

I admit it's rather draconian, but the way it was explained on the Smokstak forum, it was for use when all else fails, as in when pounding on the piston doesn't work.  Clearly there's a difference between cranking on a grease gun for all it's worth and just enough to budge a rusty piston loose.  You have to use common sense and "feel" while you're doing it.

But if water works, then by all means.

Good yarn about the SSN.  Funny how such a simple problem can disable all that technology.

I was just looking for the spec to make sure, and of course I can't find it now, but I remember when I rebuilt my 6/1 that the crankshaft was supposed to have 0.003" end play with the main bearing caps fully torqued.  And, yes, the gaskets are used to adjust that.  Fortunately my engine was about right, as close as I could measure so I left it alone.  The TRBs shouldn't be preloaded.

Funny, I did an Alaska cruise a couple of years ago with my kids.  It seemed EVERYWHERE we went they had named schools and libraries and shopping centers for my favorite poet.  Very sensible folk, those Alaskans!

Till I came to the marge of Lake Lebarge,
and a derelict there lay;
It was jammed in the ice, but I saw in a trice
it was called the "Alice May."

And I looked at it, and I thought a bit,
and I looked at my frozen chum;
Then "Here," said I, with a sudden cry,
"is my cre-ma-tor-eum."

Some planks I tore from the cabin floor,
and I lit the boiler fire;
Some coal I found that was lying around,
and I heaped the fuel higher;

The flames just soared, and the furnace roared
— such a blaze you seldom see;
And I burrowed a hole in the glowing coal,
and I stuffed in Sam McGee.   ;)

I GOT MINE!  Sorry for shouting.

A quick visual scan and I'm not disappointed.  Looks like it has a lot of good information, diagrams, and pictures that will make me want a genuine Lister even more.

As far as driving the piston out, they guys on the forums at Smokstak.com recommend filling the cylinder with grease, then place the head back on and make an adaptor to fit into the injector hole with a grease zerk on the top, then get out your grease gun and start cranking it full.  It'll make a mess but everyone says the hydraulic pressure you can build up works well to pop the piston loose.

Like the virgin bride said to her new husband on their wedding night, "Well . . . it's DIFFERENT!" 

Mine's an Ashwamegh.  Perhaps that's significant.  The intake valve guide must be pressed in and out and the exhaust valve guide is threaded and screws in and out.

The drawings clearly show that the intake and exhaust valve guides have a different appearance. 

[edit] Just checked a parts diagram for a PowerSolutions 6/1 a friend sent me and it also shows different intake and exhaust guides with different part numbers

Ok, you piqued my interest.  I just tried and yes I CAN start my 6/1 your way.  It's just not the way I've been doing it.

Check the intake and exhaust valve guides one side is press-fit and the other is threaded.  Other than that, they appear to be symmetric, so it's more a question of the external manifold plumbing and camshaft.  However the valve guides are different for a reason, so if you're looking at long run times, it's probably worthwhile to make sure the head is set up correctly.

And John, just go with 1" diameter hose adapters and plumb the water using radiator hose or steam rated hose and you'll be fine.

Hi John, and welcome to our world.

I'd start by e-mailing George at Utterpower.com.  His e-mail address is on his website.  If you really want to convert it, you probably just need one new head and a camshaft, and if you think you're mechanically up to it, you could just drill out the pins and swap the position of the cam lobes one one side and you're good to go.  While it's not "right" in the purist's sense, and while the practice of using two identical heads indicates the assembler took shortcuts which might have other more serious manifestations, there's no reason that engine won't run just as well in that configuration as one with a right and left head.  The water inlets and outlets can remain separate.  They don't need to be configured with a common manifold.  And the intakes and exhausts will work fine separate.

Good luck and let us know how you're getting along.

Papua New Guinea, huh?  Read a great book about a missionary who lived with the Sawi people there.  Peace Child by Don Richardson.  Pretty amazing.

Guy, I think you're talking about an SOM, not a 'roid.  The flywheels don't have enough mass to sustain engine rotation while you slip the crank off the shaft.  Crank the engine over three times, then flip off the decompressor while approaching 6:00 position, then pull up HARD and when the engine pops the first time, slide the crank off and you're running.  The flywheels on a 'roid weigh only 125 lbs each.  I think the SOM flywheels total about 600 lbs.

Hi Firefly.  Welcome to the world of heavy metal (mostly poor quality cast iron).

Was that one of the engines that OSL had on hand when they closed their sales out of the Southeast? 

That engine has some problems.  You've got some work to do if you intend to run that engine.   :o :o :o

First, a complete teardown is necessary to get rid of the casting sand in the sump and wherever else it has gotten to.  The oil pump will have already picked up some of it and squirted it into the bearings, so consider them history.  The tapered roller bearings (TRBs) are available from India, but you never know.  Get a set from a recognized company.  The Timken part number is 32211M90KM1.  There are others.  Any equivalent purchased in the US should be OK.

The rust looks pretty superficial but it's not a good thing and indicates the engine was left partially assembled out in the rain.  Your rings are probably shot.  I don't think condensation from your subtropical climate could do that.  And the way the cam lobes are contacting your tappet heads indicates it wasn't set up right in the beginning.  Your tappets will never rotate unless the lobes are off-center approximately the width of the cam lobe.  You need a new camshaft unless you can find someone who can do some brazing for you. 

If I were you, I'd order all the wear parts, i.e. rings, wrist pin, rod bearings, bushings, a gasket set, a spare head gasket and a camshaft.  And it wouldn't hurt to have a piston and cylinder sleeve in case you find they are badly rusted.  They shouldn't be very expensive, and a piston that size makes an impressive pencil cup for your desk until you need to use it.   ;)

Think of it as a project.  Take your time and get a copy of the Utterpower CD http://www.utterpower.com/utterpower_cd.htm to study before you start and you can't lose.

Speaking of running engines backwards, an exchange student from Switzerland once told me it was a common prank there for a kid to start his moped in reverse, then sit there idling until a friend walks by and asks to ride it.  When he gives it the gas, he gets a surprise.
