When we replaced the bearings on the crushers in the salt mine, the journals looked like that. The procedure was to slowly tighten the new shell while the lube man pumped gallons of grease into it, to "bed it in". Talk about smoke!
A 132,000 lb. crank shaft sitting there. The way it's sitting there, it looks like it just wants to roll right off its pedestal. Yikes, that's a chunk of iron! Be interested to get some filming of them re-machining the journals with the portable equipment they have today.
Talo used lub 48 in mill? Talo rendered beef fat, takes super high steam temps. Hydrocarbon oils at high steam temps form "crystals" in lubrication lines.
Rick (I thought this text was sent this morning, apologies if it’s a duplicate……) Very interesting video, thank you for posting. Will be interesting to see the in-place journal machining. Curious how they would align the axis of the two primary journals without spinning the whole thing on a lathe. What a massive hunk of machinery! You don’t get a sense of how large the fillet radii are on the shaft steps until you zoom in….the reversing torque cycles this crankshaft experienced must have been torturous! Your video series on this will be great to follow. Regards, Randy Musselman Wyoming, DE
Cool! I graduated with him from Beaver Falls Highschool and I attended his graduation party at Youngstown Southern and rode the train. That was all so long ago. I remember on the return leg of the ride, there was a radio playing and Ozzy Osborn's CRAZY TRAIN came on! It was perfect! Have you guys ever considered some sort of collaboration between your organizations?@@YoungstownSteelHeritage
