- VOLVO PENTA TURBO PROBLEMS.
Placed in a boat called North West 900 (Swedish) , 1995 model.
In the summer of 2020, the boat was gusting at 12 knots and 2000 r/min. Maximum speed 16 knots at 3200 r/min. When the boat was put back on the water in the spring of 2021, the boat had a maximum speed of 8 knots and 2000 r/min with full throttle. Something was wrong!
I am a member of a Norwegian facebook group "Vi med Volvo Penta". Posted video and pictures of the problem and got lots of tips/suggestions :-)
I'm not a mechanic, but I did what I could and listened to advice. The result was a turbo that worked again. There's probably a need for service, but I can take that for the winter. Now I know the problem if it should occur again.
Hope this video can help others with similar problem

I must say it amazes me to learn that this turbo was not dismantled and cleaned completely.
You have to decarbonize the exhaust side of the turbo.
And probably even change the bearings.
My uncles boat running twin TAMD41A. Starboard engine started bellowing black smoke when he went above 1500 rpm. He shut it down right away and ran back to the mooring on the port side engine. I took the air filter off to find the turbo was stuck. Had to use a socket to free it up by gently moving it back and forth. The exhaust side was badly caked with soot that was restricting the exhaust flow. It does not take much to stop a turbo from spinning at startup. I cleaned the exhaust side with a pick, an old flat blade screwdriver and a vacume cleaner to catch all the caked on soot. It works fine now.
If you start bellowing black smoke like this. You have to shut down as soon as possible to have any chance of saving the turbo. The longer you go, the hotter the oil in the bearing will get and it will just gum up and stuff the bearing.
Thank you.. My TaMD61 does the exact same thing….. Now i know where to start thanks to your post…
You extract some good information. Thanks 👍
Thanx for the video! Now I know what I have to turn my attention to in my engine👍🏻👍🏻
Thx for feedback :-) How I Built Outdoor Sitting Area
Oven cleaner work a treat on the exhaust part of the turbo……but you have to remove it to do it properly.If you remove the air filter housing you can us a cordless drill and a socket to move the turbo….
Great vid Steffen, glad to see you getting the turbo working again. I can only recommend you to get a new turbo from Greg before next season, I changed mine this summer and it makes the engine stronger in the mid-range. Shouldn't you get about 3.800-3.900 rpm at full speed on that engine, or is that just for the KAD42?
GREAT VIDEO! THE BEST! THANK YOU. I HAVE THE EXACT SAME ISSUE.
I had a similar issue w/ a TAMD74 turbo. I was told by an old diesel mechanic to use diesel fuel. Let it sit then I used a little wire wheel on a a drill to clean it out. Used a vacuum to suck it all out. Then used some liquid wrench to let it dissolve some as well. No more problamo!!
Very informative, thanks
Thanks mate, you saved me a lots of money. Hats off for ya. Cheers 😘
Thx ♥️ If you want to fix it 100 %, you might send it to turbo repair. Nice to get positive feedback 😍
@@steffenr.halvorsen287 Hej - tænker jeg kan skrive på dansk😁 hvordan kan det være at den det ene år går 12 kn ved 2000 omdr og det næste år kun 8 ved 2000 omdr? Jeg troede at omdrejningerne var konstant med omdrejningerne gennem gearet til propellen?
Jeg har nemlig en viksund 900 med en TMD40C, hvor jeg døjer lidt med det samme. Den går 6-6,5 kn ved 2000 omdr hvor jeg tænker den burde gå omkring 8-9 kn. Den ryger dig ikke sort på noget tidspunkt. Men altså jeg troede at 2000 omdr er 2000 omdr - men det hænger måske ikke sådan sammen?
Båd hilsner fra Danmark😁
This has happened to my 2002 AD41-P twice over the past 20 years. I have successfully cleared it out without damage by removing the turbo by unbolting from the intake side. the turbo with the blades will slide out as a unit from the exhaust elbow. Once the turbo is removed, you can get in the elbow and carefully grind away the corrosion with a Dremel tool using a stone grinder end. Once the circle of the exhaust race is smooth and clean again, try popping the turbo back in and check for free spin. Sometimes there is still a spot or two to grind away. Now I have my turbo working better than ever. This must be a common problem, since there is salt water on the exhaust side that corrodes the iron. If you let the boat sit too long without using the turbo, the corrosion invades the blades, and they lock up. Also, replace the 5 or 6 bolts holding your turbo to the elbow using stainless steel.
yes I had exactly the same problem with my TAMD 41 2 or 3 times .... before starting I check if the air turbine is running well, and if not a little WD40.
Yes, I’m interested in a video of the disassembly.
Ik had hetzelfde probleem en heb de volledige turbo vervangen (2500 €). Is regelmatig volgas geven voldoende om dit probleem te vermijden ? Volvo Penta 75D2
Have a similar problem with my Volvo D4 engine. Just found your video. Do you have a disassemble video
What is your boost pressure ? That is the critical piece. That turbo should most likely be replaced. I am replacing both my Turbos on my TAMD74P-A motors due to delayed spin up from defective wastegate.
Hola cómo solucionaste el problema
Kanskje du kjører med for tung propell....da vil motoren alltid gå for tungt og sote..... Men.... Det er ikke unormalt med litt sot da huset er vannkjølt og vil ikke brenne seg rent....
Takk for videoen. Eg har en Volvo penta tmd31a med samme problemet som du viste her. det blir bort i båten i løpet av uka og se om ikke dette hjelper.. samme problem som du har med bare 2000 rpm.
Problemet er vel at saltvann på eksossiden setter turbinene fast pga eksospartikler og rust. Jeg tenker demontere motor i vinter og sende den på overhaling
what happened when you serviced the turbo ?
Do not idle a modern diesel for more than 10 minutes. Start it, let it warm for 10 min then operate under light throttle until fully warmed up on the temp gauge. After that operate as normal.
This turbo is coaked from idling too long.
Just spray MR Muscle owen and grill foam into the exhaust side. Wait an hour and start , drive hot open again spray again and wait. Start again , driving hot. Spary again and wait, start and drive
Have you tested this solution your self? Seems like a possible solution to remove burned stuff on the exhaust side 👍
You can remove the Turbo and have it machined out and a stainless steel sleeve fitted to take care of corrosion .
I would not wait but take it apart and clean it. I think the liquids for "cleaning in place" do work but since you have so much thick deposits, I would not trust those cleaning agents. It wouldn't be good if a large flake of crap hit a turbine blade at high speed. Mechanical cleaning isn't that hard to do.
Looks to me like an over-fueling issue, most likely a bad injector.
Its a worldwide problem with pretty much any turbo regardless of engine make or model esp ones used in saltwater.
The salt air causes the cast-iron exhaust housing to "bloom" esp after the engine has been run then let sit for a while. Make no difference if its a watercooled housing or non watercooled exhaust housing.
As somebody already commented a properly machined and radiused stainless sleeve can be inserted into the housing.
hi@all... modern diesel is full of vegetable bio oil shit. use the best stuff you can buy and drive it empty every 8 weeks. put 1:500 outboard 2stroke oil to the diesel for better selfcleaning. this is pretty good for the injektionpump ! regards....
Let me apologize in advance for this comment, but some people shouldn’t own a boat, clearly the boat lacks a comprehensive service schedule. These crazy methods are all wack…but as I said…I’m sorry in advance for saying this
Totally useless.first of all need to open , and clean, second - to check exhaust valve seal, because it is abnormal carbon.may also check Pmax
Worst diagnostic skills I've ever seen here. Your turbo is coked up badly on the exhaust side; forcing it to run at speed is probably wearing down the vanes on both inlet and outlet sides. You can and should carefully--carefully!--chip away at the coking with fine tools and picks, with a vacuum hose positioned right there to suck up the debris and keep it from falling into the works. But that turbo needs some professional attention STAT.
Thanks for nice reply on my skills 🥰 The turbo has been working fine after I got it running, but I know it needs some professional attention. As long it works great now, I can wait until off-season.
