Renko gets new fuel injectors
ฝัง
- เผยแพร่เมื่อ 26 ก.ค. 2022
- In this video we replace the N60 fuel injectors in Renko's Detroit Diesel 471 with N50. We then give this engine as well as the 453 in Mammoot a tune up. This involves setting the valve clearances, the injectors heights and running the rack.

Stu, I’m not sure if you are planning your content but it’s really interesting stuff and loving it. Wish I had a mate like Adrian, he’s a great mechanic, encyclopaedia of diesel info, mentor and decent bloke….you two are the ultimate dynamic duo. I think you need to get a bigger boat. Reckon is sounding sweet.
Thanks Gordon. Most of it doesn't get planned, it's just a case of doing what needs to be done but I am trying to plan more of the outboard repair videos to support the new website. (outboard.dangarmarine.com/guide)
@@DangarMarine I have a 25 evo that needs a new leg and a 70 Johno that needs the rams done. Both should run. I have all the parts. Hit me up if you want to borrow them for some content. They would then be for sale too. cheers.
Gidday Stu, love the technical videos on the Detroits, keep them coming. What is the name of Adrian’s business and where is he located. Have a couple of 6 - 71 that need the injectors overhauling.
cheers
Jeff
what treasure Adrian is. So much knowledge that man has.
He sure does know a thing or two!
9:30 The engine room on Renko, particularly the engine itself, is all looking quite spiffy!
Thanks Mark!
Finally getting that engine dialled in and I can see the attraction. Without a diesel mechanic with the knowledge on these motors you would be stuffed getting anyone else to conquer them. Amazes me these engines may not have the best by modern standards emissions but the ability to rebuild virtually everything and recondition the motor many times saves the planet a lot of CO2 in production of a new one. Proof the American's had there metallurgy dialled in many years ago and something the Chinese will never work out.
Chinese metallurgy is fine if you buy their stuff that isn't for the foreign market. Cheap gets you cheap.
Diesel engines really are a different world. So glad you have Adrian on board. He is a diesel encylopedia.
The fuel side is definitely very different from a petol engine.
Great seeing Renko's engine compartment looking so tidy , You really did a good job of bringing the boat back to top shape . watching you pull up to Adrians boat made think your boat handling skills have are top notch . Best to ya mate from San Diego , Calif.
Thanks mate. :)
the slow and easy method with the crane worked well. lol thanks for the chuckle.
Glad we didn't put it through a solar cell!
I always appreciate the National Geographic update at the end of your videos Stu.
Thanks John!
I don't care what anyone says you can't beat the 71 series Detroits
Agreed!
Stu and Adrian do boats. I love it. Some awkward shadows around 3:00 but y'all will get the hang of it
Thanks mate.
Stu, you could install a low pressure spring check valve in the return line. You would not be using the check valve function of the valve only the low pressure spring function to keep the return line primed. Available from stauff in a number of pop off pressures. Figure it’s best to fix it as you may be likely to run the tanks low again at some point. Reach out if you want more information.
Cheers, Dan.
Yes, definitely sounds like the way to go.
At 4:10 when I saw Renko I thought WOW. All that effort and look at her now. What a great thing to do.
It is nice having all the work done now and being able to enjoy the boat.
23:17pm here in Scotland, just seen the upload so now have to watch before sleep prevails….
I hope you enjoyed.
@@DangarMarine didn’t make it, But caught up this morning. 👍🏻
I'm always so impressed how much and how detailed Adrians knowledge of the engines is. Quite busy myself, finally catching up with the videos.
He sure knows his Detroit's that's for sure.
Hey Stu! Good morning from the US. :) Been watching your channel for about a year, started when I bought my first boat and outboard motor. Your videos gave me the foundational knowledge to rebuild that motor, I’ve now done two more and am out on the water all the time thanks to you. If you don’t already have one, you should consider promoting a patrion or similar crowd funding site for your viewers to donate. It’d help solve your fuel issues and help some of us pay you back for the Knowledge you give so freely.
Thanks Glenn, glad to hear the vids have been helping you get out on the water. Yes, have a Patreon site running for the channel. :)
Excellent! Another Dangar Marine video. Always looking forward to the next one getting posted, thank you Stu.
Thanks mate, glad you enjoyed it. :)
Nice docking maneuver, like a pro.
🤘😎
Thanks ✌
Very pretty approach in Renko!
Fab. Love the studio switch-a-roo and a great vid. Thank you!
Thanks mate. I'm experimenting with some permantently mounted lights and cameras in that workshop and facing that way is the only way that works.
You can tell it is the dead of winter there, Stu is looking like a homeless hippie and he's even wearing shoes! Must be down in the 60's (F) 😁
we were in sydney in july a few years back, when we arrived at the motel she said it had electric blankets, l thought why would you need electric blankets this is australia not nz, but l soon found out it can get quit chilly in winter when that sun does not come out
Hahahahah
It's about -10 Stu at the moment.
In BC, we’re in the mid-high 30’s. Smoke-free!
I grew up in Canberra which is easily 10deg c cooler than Sydney but Sydney homes are less prepared for the cold and aren't as insulated and often have no central heating so it can seem colder here than in CBR
Your getting there Adrian is a good teacher
Well done with the new injectors. Sounds great.
Thanks Robert, it's nice to be running around with injectors that I put together and tested myself. Very satisfying!
She does purr.
You parked Renko like captain Ron. Scared me but proved you knew what you were doing haha.
Thanks mate. Fortunately Renko is a pretty easy boat to drive!
Glad you are using the tune up tools I sent you.
Thank you Dan. They have been super helpful!
great details - I'll probably never own a detroit, but if I did, I'd be much more confident now!
I'm glad to be learning more and more about them with Renko having one. It always gives you confidence to head out to sea knowing your engine well.
Definitely like seeing you and Stu , keep it up 👍
Thanks, will do!
Thanks for the film guys. You two are the best diesel mechs on you tube.
Thanks Stephen, glad you enjoyed it!
Love love love your vids. Please dont stop. Cant wait for the next one.
Glad you like them!
didnt know you were giving away.
fascinating! learnt so much today.
looking forward to future episodes
thank you
Glad you enjoyed it!
Got to say that im enjoying the way the channel is at the moment. You and adrian work well together and make for good viewing.
Thanks mate, great to hear.
I could watch n listen to you guys all day everyday. Glad you're able to keep producing content.
I've got an SR2 and an SR3 here, one day I'll get them sorted out in my spare time......
Keep on keeping on. 👍👍
Thanks Michael, we'll definitely do some vids on the Lister as we get it a health check and fix it up as neccessary.
Adrian is a really super good mate.
My dad used to say it's just as easy to keep the top of the tank full as it is the bottom of the tank.
always great when you and adrian are together
Thanks Mike!
20:38 Boy does that motor sound sweet.
Thanks!
That’s a cool oscilloscope / multimeter. Now I want one.
It is pretty handy.
brilliant stuff as always, could watch way longer vids too!
Thanks mate, glad you enjoyed the vid.
cool looking forward to watching this later. doing testing for videos today on my 60hp merc but taking a break. too hot out right now even in the shade. needed to charge up the battery first anyway.
Charging a battery is always a great excuse to take a break!
Nice job, sounds good. I still like my old Gardener diesels, like so many great engines destroyed by the 'greenies'. Take care - regards.
G’day Stu , I started watching your channel because I enjoy technical work on old gear , mainly restoration to working and this has been a great platform to enjoy , which in turn led me to Brupeg with Jess and Damian and now with you and Adrian it’s been bloody great and thanks to all of you 👍😎🍻🍻🍻🍻 , Kim . p.s I’m a 4x4 nut but this works for me just as much mate !
Thanks Kim! A little bit of 4x4ing in this weekend's video that will be uploaded soon. :)
@@DangarMarine Look forward to it mate 👍🍻
Great job love your videos
Thanks Bill.
Great video thanks for sharing
Thanks for the visit
Looks like winter is being temperate for you and Adrian. Interesting to see diesel stuff I know nothing about.
It's not too bad, but there have been some cold days. It is more the rain that has been a problem lately.
You know it's winter because Stu was wearing shoes.
Thanks
Thanks for your donation Ben, much appreciated!
One way valve in the return line ? Look forward to more of the Detroit fleet.
Best wishes from NZ
The hard starting is obviously something not shown on the vids. One of the things I've always enjoyed about this motor is the way it BURSTS into life at the first touch of the button. Eager to go do some work. A gas motor can be this way with the right recurve in the distributor.
It was a change. It's a amazing how quickly this engine starts when its got fuel. You just look at the button and it is off!
Thanks!
Thank you for your donation Tom, very much appreciated! Going straight in the fuel tank. :)
The idea that comes straight to my mind is a baffle in the fuel tanks and a baffle bypass (level balance) valve. Close the valve and only fill the smaller section of the tank to get more level for fewer bucks. No idea how practical that is in your layout and cleaning out fuel to make it safe for welding etc…
I've never seen a Marine Detroit diesel, but I now consider myself the 'Go to Guy' if anyone has problems with afore mentioned engine. Especially fuel injectors. (Thanks Adrian and the apprentice Stu) Great video as usual.
side bar: I wouldn't go near the frikkin' things all things mechanical hate me. I'd contact someone who knows what the hell they're doing.
LOL. Love your work! :)
Adrian , I’m not sure if you are planning your content but it’s really interesting stuff and loving it. Wish I had a mate like Stu, he’s a great mechanic, encyclopaedia of diesel info, mentor and decent bloke….you two are the ultimate dynamic duo. I think you need to get a bigger boat. Reckon is sounding sweet.
Thanks mate. Fortunately Mammoot is quite a bit bigger than Renko (will do some drone shots soon) so should be quite a good work boat.
I woud swear with the old N60 injectors I could always hear sort of an assymmetric throb in the engine sound.. now it sounds ultra smooth.
....nice one, a good tune up save a few dollars on fuel expenses...keep safe..
Great point!
Yay Dingo Stu FTW!!!
i keep everything full. treat the 3/4 mark as half and 1/2 mark as empty once you get used to doing this you will never run out of fuel, and will have less issues stemming from condensation in the fuel
Yes, as you say, once it is full you don't spend that much keeping it that way.
Lookin like Grizzly Adams lately.
LOL
Mate, you guys crack me up. And you’re wearing boots Stu… What… Great video as always mate. Looking forward to the next one. 👍🏻🙏🏼⛴😎
Thanks 👍
I have no idea what is going on, but still enjoyed watching
Glad you enjoyed!
Nice video 👍
Thanks you.
Slow measured approach??? We call that Hold My Beer and Watch This!!! LOL Great Vid Stu!!!
Thanks mate!
No more Mohawk, it's good to see skills being passed on. Awesome.
I think the mohawk is more of a summer thing. :)
Yep winter things got it.
The auto translator calls you Dan Gastro !!!
It does. I feel the need to make "Vote 1 Dan Gastro" t-shirts just to confuse people. :D
Hi Stu, IV only worked on one Detroit engine, it was a six pot (don't ask what Model) but it was on a 450kva Genny.
I found it like a cat engine but with out needing special tool kit,
I did do a cam shaft change and was able to set everything using a set of digital calipers and the correct measurements.
I know yours is two stroke and mine was four, but Adrian words were so right and took me back 12yrs.
Don't we all just love old school engines.
No computers........and low voltage sender error codes.....limp modes ect.
Nice job chap...... running sweet again.
I know what you mean about no computers. Adrian and I went to a diesel truck breakdown during the week. It would crank but not start and turned out to be a single wire that affected the computer opening the injectors.
@@DangarMarine tell me about it, I work on heavy plant, and doosan are worse for wiring....
Miss fire on a 22t excavator turned out tobe cracked injector wires inside rocker cover
Check valve in the fuel return line will fix the drain/air issue.
Yes, I didn't realise you could get them with a pressure rating so they will allow fuel to flow in the one direction but only under pressure.
Damn I've missed your sense of mechanics humor! Good one Stu!
Thanks mate, glad you enjoyed it. :)
I like the keg of beer in the speedboat. Was that to show scale? LOL!
That beer keg is actually the fuel tank for the outboard. Nice and robust!
Hey Stu. That’s actually a great idea. And what’s up with the reply after yours? Somebody hijacking your channel?
I just rebuilt a Edelbrock 750 carburetor for my Chevy 454. Nothing like these crazy metric motor's fueling. 😁😁
Nice work!
I love DD 2 cycles
Me too!
About to tear into a car engine in order to prep for a motor swap. Good to know I can use a MarkAll (grease pencil) to mark my bolts etc etc. Handy stuff!
use your wifes lippy, its worth it just to see the look on her face the next time she uses it
They are great markers, perfect for that job.
Damn, Skipper. I twisted my ankle last night, thought it would be ok this morning (hah!) had to call the boss up to cancel 1st day back after a 6 week summer break just now...... Shyyyyyyyytttttt.!!!!....Thanks for taking my mind off my woes!!!😅😅😅😅...Love these movies, next best thing to being there and great to see the Detroit get a little tlc. Sounded great too, nice work!
Hey mate, sorry to hear about your injury but glad you enjoyed the vid!
Renko's engine area is clean, which I would imagine makes working on it a bit nicer.
She sounds mint!
Does sound nice with the dry exhaust. :)
Hey Stu, have you been hacked?
Bery good
You're looking healthy mate, so are the chickens
Thanks Jacob.
Maybe fit a balance tube between the fuel tank outflow and the fuel return? I can’t see that affecting anything else, so long as you keep the original fuel return to the tank open it should just find it’s own level….(edit) or maybe just a one way flow valve(non return valve😁) on the return line?
Don't forget the govna luv.
you can put a check valve on the return will give a tiny bit of resistance and stop the drain.. it's fairly common most good diesel shops have them it's just a ball with a small spring should be enough to stop syphon but not disrupt return fuel
Yes. At first I was thinking a check valve wouldn't work on the return side as the flow is in the same direction but one with a very slight bit of resistance that opens when running but stays shut while off might do the trick.
Who's that guy with hair 😄
No realy he knows his mechanics. Detroit seems to have made a really nice engine. As you say he had a few choice words for the guy making waves when trying to use a crane.
He's in disguise!
5 whole minutes for the rebuild? It's all about time management lads, good on ya
It was a bit of overkill. ;)
Mate intall a check valve on the return line near the tank so it need 15 psi cracking pressure that way it won't do what it does, just friendly suggestion cheers from Canada
I was thinking that might be the only way to do that with a check valve. A normal one-way valve won't help at all but a pressure rated one would.
Pro tip: Drop a couple of house bricks in the fuel tank and the level will be instantly higher.
Good thinking!
Check your manual fuel pump. Had a Detroit in a boat I worked on like yours. Fuel pump seals were going out and it was getting air in lines thur the night.
Adrian rebuild the fuel pump about a year ago but definitely something to check in case a seal has failed.
‘Maybe you could hear him [Stu} in the background.’ Lol, I could hear that Detroit from just north of Detroit! Be well.
Hey Paul. It's my way of telling people in the distance to put more beer in the fridge. ;)
Stu, love your vids. Adrian is fantastic, now if you were only closer to me... My 371 genset needs a little loving! When is Adrian getting his own UT channel.
Thanks mate. Adrian and I will most likely keep posting the boat stuff here but will be starting a car / truck channel together too.
4:20 Nice Parking.
Thanks!
D-squad on tour😀
Roaming far and wide!
23:50 install a check valve in the line to prevent backflow of air into the rail. Detroit SKU#: DDE 23535724. Also make sure fittings are tight on the return side.
It's my understanding that those check valves are only useful in the inlet side as the return line is draining back in the same direction the fuel normally flows therefore the one way valve won't help like the inlet where it drains backwards.
@@DangarMarine nah mate, it goes on the drain side, prevents the inlet side from draining back. Keeping the inlet side full of fuel so the engine will start easily. Look into it if you don't want to take my word for it. Also provides for the proper fuel restriction. Your not pullig air from the inlet side(unless you have loose fittings or are out of fuel), your pulling it from the drain side.
@@DangarMarine I believe that is a spring loaded check valve too, so when the engine isn't running the spring will keep it closed so no air can migrate back into the fuel rail. Frightfully expensive though, I'd look into a generic spring loaded check valve and keep the restricting fitting in the head.
Check valve in the return line is the best way to stop loosing prime check valve in suction line is another set of problems.series 60 or series 50 will loose prime as soon as you turn off the engine two cycle will do the same thing easy fix
You could try putting a loop in the re-turn line up higher than the rack.
Yes, loop would help but the trouble is the rack is pretty much level with the deck (given the coaming and hatch) so I can't really get higher.
Hey, I'm from Australia and I can't look past the yacht in the background. Its a Gwen 12 sailed here in Melbourne in large fleets in the 1960's. How amazed I was to see one on show in your youtube on the other side of the world. My brother sailed in championships all over Australia in one. Whats the story? Cheers!
It's just the sail from an old Gwen 12 I restored about 20 years ago that I now use to keep the rain out. Is Sydney really the other side of the world from Melbourne!?!? ;)
Fascinating! Learn something new each time. Those engines are actually quite complex to get tuned it seems. I never knew. So is that barge ya'll bought to use for diving and what not? Or is there two different barges? Like the one adrian was cutting on an episode ago? Anyways, thank ya'll for sharin. Always a pleasure
Thanks mate. That barge is just one we borrowed from a local oyster farmer, not the one he was cutting though.
@@DangarMarine ah i see😉 makes sense now
“Believe me, my young friend, there is nothing - absolutely nothing - half so much worth doing as simply messing about in boats.”
Maybe a day tank? Pump and polish fuel from main to day tank.
Just a quick note, appears Renton and MV Jesse, (port stephens Ferry) share 2 things in common…same Detroit, (yes i asked whilst on board lol) and now mechanic (Adrian)…. If so, Shane says hi
Yes, Adrian has been giving them a hand with their Jabsco pump.
Could you lengthen the return fuel line to dip below the tank level?
I guess you could put a checkvalve into the return line to stop the bleeding out
no sht. Adrian has got a winter hat on. let it ride gentlemen
Only because it is winter here.
@@DangarMarine yeah. I figured. great vid dude.
Hey Stu if you could run a piece of flexible hose in a loop lower than the bottom of the tank on the return line would that stop the run off of fuel and solve the problem for just a piece of hose and a couple of clamps... hopefully 🤷♂️
A loop higher than the top of the cylinder head would definitely help.
Am so glad you two found each other, A match made in heaven. Maybe we will start seeing videos of two guys in black leather with moustache’s 😂
You can find anything your heart desires with a quick google search. Good luck!
The Snark is strong with this one...
LOL
Hey Stu. Love your work. Whats with the Gwen 12 mainsail hanging from the rafters?
Thanks Mick. It's just keeping the rain and wind out of the workshop!
