We just completed a full rebuild on the “office” starboard MTU This was a full rebuild as we found damage on the crankshaft which had to be replaced…. Took 3 months to get one from MTU. Made in India :(

Here is the video

 
Very cool to watch Pascal, thanks for sharing!
 
Nice vid. At 2:06 when they are installing a piston, it looks as though the liner is not fully seated but when they were installed it appeared they were?
That is one heck of a big as$ torque wrench LOL.
 
Cool as chit. I could only imagine being able to rebuild an engine while in the engine room. :)
 
Very cool / interesting to watch. Can only imagine what the price tag on that was!
 
Holy smokes! I knew it was big $$ but had no idea that much. Big toys don’t play around!
 
Very cool! A few questions to help me understand what I was seeing

Why was the O/H required and what happened that the crank was toasted?

The crank has counterweights. Did the new one come with those installed?

Was the crank journals lined bored in situ?

What is that stack of square "gaskets" installed and stacked together?

These engines usually require an inframe at 4000 hours which we were at. A typical inframe includes new pistons, liners, heads, injectors and pumps, bearings etc. that’s what we did on the port engine last year after finding oil in coolant.

On this one we were going to do the same as the oil samples showed increased bearing wear as well as traces of fuel in the oil. We had all the parts ready to go in June to be done before hurricane season really heats up in July. When they dropped the oil pan, they found damage to the crankshaft incl heavy wear and some rust. We have very limited maintenance records (the price of the boat reflected that …) so the mechanics believe at some point the raw water pump popped a leak which wasn’t detected on time and some sea water got in. The raw water points are gear driven monsters… over $10k each.

So at that point it made sense to do a full rebuild incl polishing the camshaft, new camshaft and main bearings, new damper, etc.

Yes the crank came fully assembled. It took over 3 months to get it, made in India, inspected in Germany.

Water is such a lousy mechanical lubricant! Imagine how much our world would change if it were a good lubricant!

Swimming might not be much fun and Pascal's charters would be, well, different. :ROFLMAO:
 
Fun to watch. Thanks Pascal.
A little larger than the engines I've ever rebuilt. lol
 
Pascal, Thank you for making my day. I thought the rebuild of a 454 in the boat was difficult!
