Those bronze pieces look outstanding next to the green paint, cant wait to hear that motor clear its throat for the first time, gonna be epic!!
when making gaskets we used to lay the gasket on the casting and lightly tap around it with a ball peen hammer and it cuts out the gasket to size, can't wait to see the engine in the boat Stu.
That's the way my dad taught me. A roll of gasket material used to be part of my on the road tool kit
@@bigunone And if you forget the gasket material, there was always a Corn Flakes box.
Love the fact the life for Stu does not require a working clock. Time stands still, way to go Stu!
Stu. The O ring plate wasn't quite assembled correctly. It looks like there is a groove in the end plate where an O ring goes. In reality there is a one time use removable U shaped steel spacer there that should have been knocked out, then the bore thoroughly sanded / cleaned. . The correct sequence is gasket, O ring plate, O ring, steel spacer, second O ring then the brass end plate. If you look closely @30:01 you can see small holes at 12 o'clock, and 6 o'clock, one on the outside, and one at the O rings ( two holes, each end in line with each other). These holes along with the steel spacer let any water leaking passed one of the O rings just leak out instead of cross contaminating the cooling system. Make sure all four of these holes are clean. Also, when assembling the heat exchanger , install all the bolts just snug on both ends, then tighten the bolts on the O ring end first, then the flange end. This helps keep everything centered.
Ah, you may have answered a question I had about a part I have that I didn’t know what it was. It is part 5167745 described as a “Gland”
@@DangarMarine Yup, that is the piece.
Got it apart now and can see exactly what you are talking about. Thank you! You are my new hero. :)
Cheers to Bill on this one. As Stu says in the next video, well done on the gracefully and respectfully aspect.
@@peterjensen6844 Thanks Peter.
When I was a manager at a Volvo heavy equipment company, I would always walk back to the shop to watch the technicians work, just to marvel at what they did. It's very soothing
Stu's vids are very soothing, time goes by and it's a trip to the barbers.
Just one tip when using acid based descaler in a soak tank; dissolve some soda crystals (washing soda) in water in a washing up bowl and keep it handy in case you need to quickly neutralise acid splashes.
Good tip!
Quality work means you can sleep tonight and know you won't have trouble tomorrow. Great video Stu, attention to detail is a must!
... and, just as good, I can sleep well tonight (and during your/the future travels).
Thanks Matthew. :)
I was so nervous during the soak. You had the solution filled tub half on and half hanging off of your bench. I though that any second the tub was going to fall off of the bench and crash on the floor. Great job of cleaning the exchangers.
Stu has got to know just how much that can bother people halfway around the world! Sitting in St. Augustine Florida worried about a bucket falling off a bench in OZ is not how I planned my Sunday morning!
There's something too cool bout a clean , well maintained engine in a boat . I use to clean my yanmar with a q-tip it was reassuring the engine ran and looked like new . The Detroit with the bronze parts really floats my boat keep up the good work . Showing some real pride wiping off that grease !
Thanks mate. I really like the bronze too.
It always melts my brain that your shop is open to the elements. I could do that for about 2 months a year.
Never gets close to freezing here fortunately!
heya Stu, yes please on the fishing video.......I'm guessing there is more beer drinking than fish catching :-) can't be anything but fun to watch.
The attention to detail is commendable. Reminds me of rebuilding the small block to my old Chevy Nova in my driveway. The end results of years of dependable use is the Payoff.
Heck ya things are getting exciting again. This really gets the old blood flowing. By all means please include the fishing trip. Thats some more icing on the cake. Can't wait to see more assembly of the engine. I think you can tell im more of a wrench man. Hey Stu including the parts of your life in the videos makes things more friendly and interesting. Keep up the good work.
Thanks mate, glad you liked it. :)
Top Tip for making gaskets. Use a print pad on the part then put it on the gasket paper. Perfect impression every time! Ant.
It's great to see you teaching about engine repair/rebuilding. As a 12v electronics guy, I'm fascinated with the mechanical side of engines. And you sir are a great teacher. And I wouldn't mind watching an episode on what it's like to fish Down Under. :)
Cheers young fella....I find these videos totally relaxing. My wife often comments negatively on my DIY skills, but I enjoy watching someone who can,,,, in typically mystifying Japanese fashion she does tell me that my talents lay elsewhere.... where, I do not know!! 😜 But thank you for the videos,,,from a Welshman,lost,,,and living in Japan!
To make a gasket, place the paper over the part and with a small ball and peen hammer gently tap around the edges including the holes..presto perfect gasket. Had that taught to me by an old mechanic. Worked for me on numerous occasions when a gasket is not available or to expensive.😁👍🏻🇦🇺
The Detroit seems to have a very simple, easy to get at cooler design. Everything is all in one location. The Cummins on a friends bought has the cooling system all over the place.
I used to make gaskets with a little brass ball peen hammer, just hold the gasket material onto the surface and tap around to cut. But you have to be careful that the gasket material doesn't shift as you tap around or the gasket will be misshapen. It helps to pre-cut the gasket material for ease of handling. And you can use the method with a piece of heavy paper to make a template.
That engine is looking good!
Great tip to use citric acid to clean bronze.
It’s mesmerising watching an engine go back together after a fresh paint job. Great looking donk Stu, I cant wait to hear it purr
Thanks Damien, hoping to try to start it early next week.
She is coming together rather nicely. Can't wait to see her in the boat.
That CFS solution you are using is really doing the job. Those heat exchanger parts really came clean.
you can also clean the heat exchanger with an ultrasonic cleaner. I have done this in the past greetings from the Netherlands
I'd like to get an ultrasonic cleaner one day. Good for carburettors too!
@@DangarMarine One large enough for things like carbs is pretty cheap off fleabay, around $100 US.
A massive amount of time and effort must go into making these videos and most of us viewers just can’t comprehend what it takes to make each segment. it’s a real credit to you Stu, we all really appreciate your efforts....well done 🍻 amazing job to now mate 👍
Thanks Nick!
Great Video Stu. I enjoy your work.
That engine is a thing of beauty, with the bronze parts contrasting against Detroit green. Wow!
WOW ! Stu is working is a clean, well organized shop !
He tricked me !! That was just the intro !!!
Stu, I commend your commitment to "doing things right". Your commitment to detail and being thorough will pay off in the long run. Great job! (and oh yes - please do post a video of your fishing pics!)
Looking good Stu... wish i was there to help ;)
Learned a lot about Heat exchangers on this episode of Dangar Marine Stu, thank you, Jeff in LA USA
Stu, that cleaning solution would do a lot to remove the skid marks from your shorts, throw them in with the parts, we all do that when working on engines,and almost anything else. great job on the engine, say hello to Daffy for me. ( give her one big one for me.)
There is no doubt but what a thorough cleaning and descaling like that will keep the engine running better and longer... so, what do you figure Stu - say once a month or so? After all, it only took you 35 minutes and 44 seconds- and you still had time to feed Daffy Duckchicken. 🤣👍
Really great! Very much enjoying the steps prior to putting the engine in. Many thanks for structuring the presentations of each part this way.
Thanks Randy, glad you liked it.
Nice job Stu, can't wait to hear that engine fired up!
I really enjoyed this one mate. It must be a joy for you assembling the engine. Keep the progress going. 👍🇺🇸
Great video, one of the best so far - that engine is starting to look really nice, keep up the good work !
There seem to be some really great products out there that I could have done with years ago but have never heard of them. You never stop learning!
On HGVs I always used copper grease if I wasn't using Loctite (or other thread lock) on bolts and nuts. Oil in threads gives me the willys as it can 'hydraulic' if the bolt is near the end of the thread and can split cast iron.
I love Hylomar and used it for decades. Rolls Royce invented it so good enough for me ..
Nice job mate. Methodical and accurate work ...
Excellent job stu - it’s all coming together quick! 👍
Engine is looking great!! Love the green and bronze contrast, classic look !!
Thanks mate. I really like the contrasting colours too. :)
One of the best videos yet, Love to see the engine coming back to life.
Straight white vinegar is good for cleaning surface rust off metals.
Good to see the engine back
The grade 8 bolts are a nice touch. The Jimmy's lookin' purdy.
A fine job Stu, your parts look ready to rock & roll once again. Thank you for the hard work filming and editing the videos.
You're welcome mate.
Go on Stu, let us see what you caught. Nice and steady with the re build makes it easy to understand and prevents any mistakes. Could watch it all day.
the engine paint and bronze/brass look awesome. Good job mate - must be exciting for you.
That lil GMC is looking spectacular. On the boats I've wrenched on had different heat exchangers. But all where fresh water only. Can't wait to see you get it installed. 🙂
I could watch theses videos all day, thank you so much for another great episode. Looking spiffy! Cheers mate!
Spiffy a word that should be used more often.
Got a lot of work done - great video!
That engine starting to look awesome he'll be like a factory new motor I like your idea on the videos keeping them organized
Love your videos. You have a good feel for what details the mechanical mind has interest in. That was great. One gets a really good feeling when cleaning and installing those parts. It will be so rewarding hearing this engine roar to life once installed in the boat.
Thanks mate, I can't wait to hear it fire up either.
Stu, engine looking fantastic. Won't it be a lovely day to hear it fire up and have the boat move again under her own power! Really enjoy your channel.
Thanks mate. :)
Engine looks great all cleaned up and going back together. Another week closer to launch!
That engine is a piece of art 👌 looks good with the polished brass
G’day Stu that was very interesting with all the work that you have put in the engine bay the motor is really going to top it off. Good job looking forward to seeing your next video. With the attention that your putting into her it’s going to be one very nice boat regards John
Nothing more exciting then starting a newly rebuilt engine. And it takes right off. Because you have done it all right. Good job Stu. wish I was helping
Its cool to see how far that's come and how awesome that big old detroit looks! I agree with mcphoneix below...can't wait to hear that baby come to life!
Winter here, So definitely would like to see you guys doing some fishing, great video
CITRIC ACID...great for cleaning inside of your DISH WASHER, as well.
Making a LOT of GREAT progress.
The engine is looking great Stu!
Can't wait for the rest...I really like these videos.
Love Daffy's after-fart reaction of just looking around like saying "What was that?" :)
Fine video, shows the things that you need to do in a complete rebuild. Those coolers came out really nice!!!!!
Thanks mate.
If I can I just make my own gaskets. One trick I do to trace from what I need it for to the gasket material as long it is not cork is, lay the gasket material on what I need it for and take an screwdriver that has an round blunt handle end and carefully do an pressed impression rubbing of all the edges. This has work for me although it's been an easier way for me also. Just a note. Thanks a big time on all that you teach. I've learned a lot from you. Take care.
I’ve been watching your channel since before you started on the current vessel. The content is really good right now, and it’s exciting to follow with you through the completion of this project. Really good personal feel to your filming. Sound is almost always spot on. Really seems refined and natural. Keep up the great work and I think there is a lot of room for your channel to grow further! Cheers mate!
Thanks Paul. :)
That Detroit looks like it's brand new. Nice work and hope it runs like a top.
Love how this is coming along Stu. Just watched another video showing a water sand blaster in a containment cabinet. You just hook it up to air and put your arms in the gloves and spray small parts. Great for a shop for sure
Hey Tim, I have been tempted to grab one of those cabinets.
Check it out
th-cam.com/video/EZ9f6GjazQE/w-d-xo.html
If it runs as good as it looks, you've got it made! Can't wait to hear it fire up in the boat.
Never been much of a mechanic (I can do the basic stuff) so I learned a lot. I really hope she ends up running a nice as she looking. Nice job!
Wow Stu....thanks for a Masterclass on Heat exchangers and how to wrangle them. I am especially grateful for your discussion of Chemistry and chemical treatments to clean up these intricate parts. You're an Alchemist Dude. I learned so much from this video. I have a raw water cooled Bukh DV20....and I've been contemplating a system that doesn't suck salt water into the engine......your video has given me a starting point in my modification journey......thanks Man
Sounds like it could be a good upgrade for you.
Great progress mate...excellent video .... informative and as you say "gettin there" . A mid week filler on your adventures down at Lake Jindy would be awesome :)
Thanks Mark, slowly but surely. :)
Just about there. Will be a great day to hear the Detroit fired up.
G'day Stu. An easy accurate way to make a gasket is to lay the paper on the job and tap it out with a 4 oz ball peen hammer [ old school gasket making],, the other thing is when you use a wad punch always cut onto the end grain of a block of wood. It doesn't dull your punches.. Good to see you've got some mallee roots on.
Probably a bit late now Stu but when you have lots of threads to clean a battery drill with the clutch set to low torque so it stalls if the thread tightens up is a real time saver. Jenbacher intercoolers I used to change out had around 40 bolts on each side of the matrix. Took hours by hand cleaning the threads.
very nice, great maintenance. also a very low pressure of air in the bucket of solution would make a homemade sonic cleaner.......
Can't wait to hear the Detriot back to life Stu! Old school GM diesel power!
been hanging out for this one
You are doing a fantastic job! Thanks for sharing your knowledge and your videos. I'm building large RC sailboats on my TH-cam channel, but have pretty low quality videos so far.
Expense sucked I'm sure but the restoration is looking great Stu! Super cool you have an engine you should be able to trust, and now you'll know all the ins and outs of it!
That Hylomar works very well. I have used Permatex High Tack for years for the same purpose. It sprays on purple so you can see it.
Great video man, keep up the good work. I love watching the old beast come back to life.
Thanks mate.
I’ve never seen a Detroit this nice great job!!!!
Great Episode!
Learnt at tonne of new techniques.
Unreal DM, Would dig to see Your fishing trip too.
I built a tank that was 24" X 24" x 48" and put 50 lbs of caustic soda in ti to clean engine blocks and heads. It wasn't working very good so I took the burner out of an old furnace and put that under the tank to heat it up. My Dad had a restaurant and some of his pressure cookers were in really bad shape, so he came by the shop after I left and put the pots and there lids in the tank. When I got there the next morning there were no opots in the tank only the stainless pop-off. tha the lids only had a small amount of aluminum left and the handels.
Aluminium sure doesn't like caustic soda!
Looking good Stu!
Yes, please upload the lake fishing trip. I believe many would enjoy it. Thanks mate. :)
Will do!
As always nice work Stu!
Sealing pipe threads a trick I learned is putty tape putty. It will never leak! Put sealant on the threads wrap the tape and use more sealant. It will even seal plastic and metal threads together!
Looking good.
Thanks for the video.
Loving the exposed bronze, motor is looking good! Museum quality.
I look forward to hearing it run!
Motors looking great
Great video Stu
excellent gasket making
Excellent video, Thank you
Amazing stuff, keep it going!
The best way i think is to use Citric Acid in hot water and it eats away at any rust and lime scale and makes it looking new again and its cheap and saves you money. and you don`t loose any metal
Good Job Stu
When you use a garlac type gasket, buy 1/8" thick material it will seal better!
With paper gaskets on cast iron, you can just hold the paper against the item and lightly tap the edges with the round end of a ball peen hammer. The sharp edges of the cast iron will cut their way through the paper gasket material. This is pretty common thing to do if you work on old tractors.
Nice one as always Stu,interesting too. You seemed to get a lot done this week,keep up the good week,take care.
