RECENTLY RECEIVED AN E MAIL ABOUT CR #2699 WHICH THREW A CYLINDER ASSY. & PISTON
PISTON WENT THREW THE ROOF & LANDED IN KITCHEN OF A RAIL SIDE HOUSE.(WITH PICTURES) 4400 HP GE ENGINE. WHAT HAPPEND.ANY FEED BACK FROM ANY BODY WORKING ON THESE ENGINES. IM AN EMD FAN BUT I LIKE THIS GE 250 ENGINE HERBYGD@AOL.COM
I first saw this on the Cargo Law website a couple of years ago. Cargo Law usually specializes in ship wrecks. I'm not that familiar with this engine but it looks like the head/liner assembly is held in place and the bolts broke. This type of failure seems to be a classic fatigue failure where somebody forgot to torque the bolts properly. I understand that on the FDL engine that the liner is welded to the head because with the higher firing pressures to make 4400 hp they couldn't keep the gaskets in it.

The head is a separate piece - unless GE started doing something new in the past decade.
What I don't get is why the piston left with the jacket/liner/head assembly?

The heads are welded to the liner and pressed into the housing, The latest greatest thing , we are scrapping all of our 2 piece liner heads and putting in new liners with welded heads. I gotta admit , we are having fewer failures from O Ring water leaks.
