I got to work on a Chicago Pneumatic stationary diesel overhaul . After shutdown it took 4 days just to be able to touch the block . Each cylinder had its own individual head that weighed 85 lbs .. The pistons were the size of a 55 gallon drum that had a threaded hole in it for an eyebolt so a chainfall could be used to remove it . Connecting rod nuts were 1 1/4" thread . Everything was just big .
I used overhaul the GE electrics on our K class iron ore haulers we used to load them to 2500 HP at around 1200 RPM from an isolated control room for a couple of hours they had huge chains holding the loco down & a funnel about 15 feet across the whole area used to shake it was like an earthquake man it used to belch out the smoke
Not sure if they still do but engine designations were the cubic inch capacity of ONE cylinder, for example an early GM/EMD was the 567- 567 CID per cylinder and were available up to 20 cylinders, IIRC!
Back in the good old days before the coal trucks took over I liked watching the coal drags come through, L&N had a lot of Alcos I always got a kick out of their turbo lag and smoke.
I'll raise you two, Del...steel toes optional! I simply cannot imagine working under that crank doing the main cap install. What must go through a persons head.
