"right click, save as"

 

Im thinking Bar table for the kitchen. Now if I could just talk my wife into the hemi Coffie table to go with it.

 

Looks like the one out of my lawn mower..... NOT.

 

Could be from a large old Fairbanks Morse Engine...the local antique club has a 4 Cylinder, 200hp model with a 13" bore x 18" stroke, IIRC. There were probably larger models available back then too!

In Calgary, FB engines are scarce.. My guess is from either a Clark TRA or a Ingersoll Rand KVS.. 15", Might also be a Cooper Bessemer GMV...If its flycut on the top for valves it could be from a LSV.. Two cycle pistons usually have a set of lower rings on the skirt.. I think the Ingersoll Rand bet is best, they are 4 cycle..

Whites that I work with only have 10" bores.

 

3616 is not the biggest engine Caterpillar makes... The make a CM-32... This thing makes the 3600's look like pony motors.
That piston looks like an old Cooper Bessemer or on old Worthington Intergral... Big old slow speed!!!.. Gotta love to old school designs, they make great conversation pieces.. hahaha..
I saw a bare piston out of a CM-32 while in Peoria of training, when I first walked by it, I thought it was an outdoor trash can. Then on second glance, I realized that it had ring-lands and a dish design in the top of it. Talked to one of the Cat instructors that happened by, and sure enuf... it was a piston for the CM....

 

good gawd, thats large. I didn't think kitty cat was in the large prime mover game.......but anyhow.


I've seen that ship engine link a hundred times before................and its still pretty cool.

 

I'm saving that picture. I'll awe some friends. I thought the locomotive piston I saw in person was huge, now that's even bigger!

My favorite quote from that page, 3rd line down: "...all are inline engines."

 

That piston is a lot bigger than the ones we had on my last ship. I was stationed on the USCGC Chase. Our engine plant had 2 main gas turbines (for high speed ops) and 2 main diesel engines. The diesels were Fairbanks Morse 38TD8-1/8-12. Each engine had 12 cylinders and 24 pistons, in a vertically opposed setup. There were two crankshafts per engine, an upper and a lower, connected to a common output by a gear system. Each cylinder had an 8" bore and each piston had a 12" stroke (24" combined stroke, upper and lower piston). Each engine produced around 3600 SHP and over 21,000 ft lbs of torque. Pretty powerful, but I can only imagine how much power the engine that DEMON's piston came out of made.

Here is a shot of a FM 12 cylinder engine. Even though this one is driving a generator, its the same as the ones on our ship. The dimensions on them are 11' wide, 30' long, and 13' tall.

 

jr, i had to change the lower crank on an 8 1/8th out of a tug boat. that wasnt fun.
but no where near the size of the monster on the 1st post

 

Being that you are in Clagary my guess is Clark, Cooper, IR. gas compressor. I run those babys and have seen the pistons a few times, but have not payed close attention to detail.


I have back fired those units a time or 2, they make a loud bang.

I was almost killed by a Clark a few years ago when it had a dead cyilinder and pushed fuel gas back into the starting air line, witch ignited. Blew up a 3inch line that was 90yards long. The line was only 6 feet directly above my head. Turns out a check valve as well as an air start valve failed. Sent shrapnell through the building and 100 yards beond. Me, another operator and a mechanic lived to tell about it.

 

Amazes me how many "close call" stories I hear.. I have a picture of a Clark intergral engine on our website front page... Little one though...

 

Man... after hearing some of ya'll stories... Is this what I have to look forward to working on Cats???.. Worst I've done so far is throw a 50 ft. flame out the muffler. It REALLY lit up the night and was kinda romantic glow....hahahahaha.. Unit went down... Was on the phone with operator as I was driving down location road... he didnt see anything wrong so he started it up and started loading. Turbo shaft was broken in half and exhaust was full of hot, dirty engine oil...
But im really not interested in seeing tubing exploding like a 40 ft. pipe bomb.

 

Working on Cats? BYOHeads. The Natural gas G3400 versions have had recent head life of less than 6000 Hours. All my clients in the province have had the same problem. Backfires blowing off the carb are quite common.
