Renko gets new fuel injectors

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)

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.

[@danielneilson867]

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.

[@DangarMarine]

Yes, definitely sounds like the way to go.

[@glenncurtis3277]

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.

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.

[@DangarMarine]

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.

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

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.

[@DangarMarine]

Thanks mate!

[@JamesDriver40]

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…

Hey Stu, have you been hacked?

[@philpritchard3442]

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

[@DangarMarine]

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.

[@claudiaoctavia6340]

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.

[@DangarMarine]

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.

[@claudiaoctavia6340]

@@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.

[@newjerseybill3521]

@@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.

[@joemaser9122]

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

[@huntm7592]

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.

[@albertomoniz9051]

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

[@DangarMarine]

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.

[@todaywefly4370]

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?

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.
