From what I've seen on here, in this application or in locomotives, EMD's are probably the the kings in the diesel world!

What's noisier, the engine itself or the turbocharger?

And they ain't looking at any alternator bearing! That's not what was replaced! They're keeping an eye on the main rear bearing. Big job to replace. I'd rather do the alternator!

[Sneighke]

That's a honkin alternator! That's gotta be loud as hell. Sounds like it was online but I didn't hear the switch-over. If it wasn't online, simply add 20DB to the whine. heheh.

@Cap10Aerobatics he does!

@whorayful The rectangular hatches were older emd engines in the FT F-2 F-3 units...and some of the Early BL-2 and GP-7 locomotives...when the 567 was introduced and upgraded the circular air box and crankcase hatches were intoduced where they remain so today..Worked on some as a RH machinist before I went into engine service with the Santa Fe 40 years ago...nothing like having to fish tools out of the crankcase or fasteners you accidentally dropped ...pass that rag...Thanks :)

@srats02 For the uninitiated, the upper row are air box inspection ports, the lower row are for accessing main bearings and big ends for power pack removal. I worked with GM Australia for around 20 years as an electrician, so I mostly stayed behind the flywheel on the alternators, but from memory as you said in the early engines I'm fairly certain the crankcase covers were rectangular, can't remember the airbox covers, nothing like being in a room with 3 of those things at full noise, peace man

@whorayful

The round holes are airbox inspection hatches..since this is a 2 cycle this is where the scavange air from either a turbo or roots blown goes for combustion ...the older units or engines (ie f's) had square hatches as info...

@Badchoicesmade These engines are the grid for a lot of pacific islands, the Americans left a lot of them there after the war, Guam, Phillipines etc. They keep maintaining them and they keep on running. The one in the video has at some time been repowered, the engine casting (round hand holes) doesn't look as old as the control panel, which has a very 1950's appearance with the GM POWER sign. EMD a division of GM used their own name for decades and usually would have EMD Electromotive Power sign
