Agree, we went to Olathe Kansas once to work on a v-16 , I wouldnt get inside it , didnt trust anyone that had controls of the air powered engine roller .

It took two of us in the crankshaft hole with a slugging wrench and a sledge hammer to remove the connecting rod nut if we were pulling a piston. I ran the building and we had lock out tag out procedures. I had to climb in the cylinder with a hand grinder to scuff the liner where the skirt had marred it. This was in NJ and we were trying to run the engine to meet the air quality requirements. The cylinder lubricators were timed wrong and they burnt up quite a few cylinders. If the liner would crack, the cooling water would flood the system. Quite an experience.
 
Mother nature getting mad. :eek:

Wow, pretty incredible George, those are cool pics!

Annnnd here comes "One up Bob" with his contribution. Have you ever been INSIDE an engine cylinder?

Well I found this, over 100K HP and 38" bore over 8 FOOT stroke sposed to be largest recip engine in the world. Pistons are 20ft tall, (I think they meant cylinders?) engine is over 44 ft

yep, and it has crosshead bearings. Largest one is 14 cylinders, ours was 10 (3,000+ hp per cyl) and the bore was 36''. The pistons with the skirt and rod are probably that tall. The piston crown can be removed from the skirt. The piston is placed on it's crown upside down after initial removal. It takes two overhead horizontal hoists to remove the piston from the hole. The first is attached to what looks like a chandelier and it is secured to the top of the piston. After removal of the nut which secures the rod to the crank the piston assembly is raised so an eyelet is attached to the bottom of the single rod. When the piston is clear of the hole the other hoist is connected to the eyelet. By lowering the top of the piston with one hoist the other end is raised until the piston is upside down. The Chandelier is removed and the piston is lowered onto it's crown. I've done this many times and your 3 foot hand held control box is what controls both hoists. The trick is when the piston is horizontal during the inversion because one person controls everything and you have to move each hoist outward and then back. The rings are removed with a tool that looks like a car scissor jack. Each end goes into the ring gap and you spread the rings to clear the crown.

What are the odds?
 
You know what they say about a ring around the moon.
Count the stars inside the ring and you will have rain within that many days.
Happy Halloween!

---strike wrench where I`m from --lol
The guy that got in the v-16 used an air powered impact wrench , it was about as big as he was , w/ long handles that stuck out the access doors.
Not my cup of tea !

Never had to go to the gym. lol
We had Swiss engineers with us for a whole year testing this beast because using one of these engines to generate electricity and steam (the exhaust could also be directed into a steam boiler) had never been done. This engine was built in Switzerland then disassembled, brought to the US and reassembled at the chemical division of Hoffmann La-Roche in Belvidere, NJ.
