What's Inside A Massive 2-Stroke EMD Diesel Engine?

[@bnkwupt]

Love these EMDs and Detroit Diesels. Robust and glorious.

[@FixAndForget]

I agree! Given these have over 100k hours now, they are certainly ones for longevity. Thanks for watching!

[@geoallen437]

Cool

[@darrenwebb5334]

EMD engines certainly seem well built. Detroit Diesel 92 series on down on the other hand are garbage. Low powered noisey leaking pails.

[@ironken1796]

I have many hours on 710's, 645's and 567's in the rail industry. Very good job explaining and showing the guts! I really enjoyed this.

[@FixAndForget]

@@ironken1796 Thank you! I appreciate it

[@PowerTrain611]

These old EMDs will last FOREVER if you take care of them. They can take a real beating, too.

[@FixAndForget]

@@PowerTrain611 both 12 cyl have over 100k hours and run like new. Thanks for watching

[@samschaeffer8236]

Fascinating. I am a railfan, but it's nice to see these engines doing other work. It would be nice if you could show the ship these are in, and tell us a little bit about them. Thanks.

[@FixAndForget]

Thanks for watching! I have a few videos on my channel of the engines from this ship and a sister running. Can't say or show much of them since they're government but thanks for watching! The other 2 engines from this video are being overhauled now so I'll probably make another video soon.

[@Terryk-s7q]

That is not a clutch that your looking at for the Turbocharger. It is a spring drive gear to turn the turbo. The overruning clutch is part of the turbo assembly. 2:00.

[@FixAndForget]

@@Terryk-s7q Thanks for pointing that out. I corrected that in another video but forgot to make the edit on this one. I appreciate it, thanks for watching.

[@Terryk-s7q]

@@FixAndForget very good video with a lot of great information and shots of parts most people never see.

[@FixAndForget]

@@Terryk-s7q Thank you sir

[@ivoryjohnson4662]

That’s looks like a few coins got dropped . Glad to see that shop puts the maintenance in

[@FixAndForget]

Overhaul every 5 years or so. Thanks for watching!

[@barryosullivan7957]

I work for Irish Rail and right now we have a 201 class locomotive in for a 1 million km exam...the 710 engine has been removed and is totally stripped down as far as the crankshaft.

[@FixAndForget]

That's awesome. Our EMD technicians are also from Ireland. Thanks for watching!

[@BruceBoschek]

We don't often get to see new, shiny liners, pistons, connecting rods and heads! Usually they are black and oily. 🙂 Thanks for the views.

[@FixAndForget]

Thanks for watching Bruce! I have a few more videos of these engines check out my channel when you have some time.

[@BruceBoschek]

Wow! You have a lot of wonderful videos. I subscribed and will be going back through them. Thanks!

[@FixAndForget]

@@BruceBoschek Thank you sir!

[@davenamanda]

Very interesting video! Thank you for posting.

[@FixAndForget]

@@davenamanda Thanks for watching and the kind words!

[@getbent876]

2550 rated horsepower at 900 rpm. FYI thats about 15000ft/lbs

[@FixAndForget]

@@getbent876 thanks a ton for the info, I've been curious. Thanks for watching

[@blackflagqwerty]

Do they have 8 throttle notches like their locomotive counterparts, Or are they infinitely variable from idle to full throttle?

[@FixAndForget]

@@blackflagqwerty They are 600v generators so just controlled by the electronic Governor and loadsharing system. Direct/reduction gear marine EMDs are variable between 400-900 RPM with air or electronic throttles. Thanks for watching!

[@rearspeaker6364]

some company wants to keep their engines and generators reliable!

[@FixAndForget]

US Government (: thanks for watching

[@dfb1111]

Can the mains be replaced in place through the lower access windows? Thanks for posting this video!

[@FixAndForget]

@@dfb1111 yes they can. Thanks for watching!

[@jnic2003]

How many hrs do they go between full overhaul?

[@FixAndForget]

Usually 32,000 but in this case we went to 45,000 with no issues. These engines still retain many original 33 year old main and lower con rod bearings. Thanks for watching!

[@deefa_damo]

Thanks for sharing. What is the expected remaining life for these very old-tech (but awesome) two stroke diesels? Until the last ships they were installed in are scrapped?

[@FixAndForget]

EMD still makes new 2 stroke diesels for marine applications. They will be around long long into the future. Thanks for watching!

[@ct1600a]

are there any rocker arm adjustments needed like on some car engines?

[@FixAndForget]

@@ct1600a exhaust valve lash and injector timing are set by adjusting the rocker arms. Exhaust valve bridges are Hydraulic lash on 645 series but still need adjustment.

[@ct1600a]

@@FixAndForget Thank you for the info!

[@FixAndForget]

@@ct1600a thanks for watching!

[@geoallen437]

That was awsome

[@FixAndForget]

Thanks for watching

[@skylerlaw24]

4:46 7k hrs before a turbo needs replaced? we get 25k hrs and thats a minimum iv seen engines go 60k hrs on the same turbo

[@FixAndForget]

We went through a bad set, poorly rebuilt. Last few have gone 32-45k hours. Thanks for watching.

[@skylerlaw24]

@FixAndForget who was the remans from we get ours from quality turbo out of houston

[@FixAndForget]

@@skylerlaw24 OEM from Progress Rail

[@robertguzzardo8291]

What are these in?

[@FixAndForget]

Diesel-Electric azimuth drive ship. I have more info in the video of all 4 running on my channel. Thanks for watching!

[@TedRitchie-cz5pu]

anyone want to buy one? out of a big tug boat.

[@FixAndForget]

I wish I had the space for a toy EMD. If you ever find some Cleveland 268a parts let me know. Thanks for watching

[@Osamailyas]

GM/EMD engines are superior to GE

[@FixAndForget]

@@Osamailyas I've never worked on a GE but EMDs are superior to everything else I've ever seen. Thanks for watching!

[@ironken1796]

EMD vs the 7FDL....I agree. EMD vs the Gevo's.....I like them both. The EMD's do seem to load a bit faster.

[@FixAndForget]

@@ironken1796 That's their claim to fame I believe. If Commanded to emergency start ours are online in no more than 30 seconds, rather unheard of for our world. Ours are kept under constant heat and lube oil prelube also. Thanks for watching.
