I ran across this youtube vid and saw something I've never seen before.  At around 3m 40s in the video the videographer walks around to the far side of the engine and . . . well, as the virgin bride said to her new husband on the wedding night, "Well . . . it's DIFFERENT!"

Anybody know this particular configuration?

Wife and I sold the house under the big drippy trees in Gig Harbor, Washington and found one we liked better on Fox Island on a bluff overlooking Puget Sound.  The groj is about 1200 sq. ft with lots of room for a shop, which I'm slowly working on completing.  Being on the island, lots of houses have emergency generators.  This one was no exception.  It came with a Lister genset.  Twin cylinder engine coupled to a 7.5 kW generator bolted to a heavy steel plate frame with integral fuel tank. 

As you can see from the pic, it's been slathered with blue paint even the rating plate, so I can't tell what model the engine might be.  I'm considering gently stripping the paint on the plate but I thought someone might recognize the engine. 



Here's a closeup of the rating plate on the generator:



The engine sounds to be running fairly slowly; perhaps 1200 or 1800 rpm.  But it makes enough noise to wake the dead even under light load.  I have both of my 6/1s stored  in the groj/shop.  Might end up selling one since we're well covered for the usual and run and heat the shop with the other one just because.

Any help identifying the engine would keep me from possibly ruining the engine rating plate with chemical paint stripper.

A friend of a friend who's not on this forum sent me the following photos of a broken flywheel.  It's from a  6/1  he says, that suddenly began knocking, so he shut it down.  Next morning, he found the gib key lying on the ground and the flywheel rim cracked almost clear through.  Reaching across a cracked flywheel to hit the stop lever like he did, he's lucky to be alive.



You can see there is shiny metal, indicating a new break, as well as dirty rusted metal which indicates the crack existed for some time before becoming critical.

In the pic below you can see how the flywheel broke.  Cleavage plane was 90 degrees to the plane intersecting the center of the crankshaft and the gib key keyway.  So it looks like the hub failed in tension, most likely because of casting flaws, which are visible in the pics, and perhaps an overenthusiastic Indian assembler on the end of a sledge hammer. 




Properly fitting gib keys would have made that kind of force unnecessary.

Anybody have any unusual success stripping the paint down to bare metal on a 'roid?  On my last engine I spent several days using chemical stripper and a sharp putty knife stripping the paint and primer.  Then I removed the plaster (yes, plaster) filler with a flap sanding wheel on a 4.5" angle grinder.  But I recall a few folks were talking about having their parts hot-tanked.  Never heard whether that woked or not. 

Wonder if there's an easier way.  I'm thinking of renting a sand blasting outfit, or maybe having somebody do it for me.

Comments solicited.
