Yanmar 3TNV82A Engine Rebuild - 3 Cylinder Diesel

[@R.E.HILL_]

So what was that weight difference between the assembled pistons and rods...?

[@Matthew-sc1]

It always amazes me to see how clean you keep your workplace!! I bet you could eat off that table after the engine rebuild🤣🤣 Thanks for sharing another great video Andreas! Keep them coming man

[@WorkshopRebuild]

The work table stays very clean and yes, I probably could eat from it😁 Thank you for your feedback, I appreciate it👍🏽👍🏽

[@92Foxbody5.0]

Could you show how to install the fuel injectors? I question the seals on the bottom of the spray nozel. I have a top hat looking seal idk if goes on injector or not

[@WorkshopRebuild]

Hi there, Unfortunately I do not have a Yanmar engine that I'm currently working on. The injector nozzle features a heat shield which is made of plastic and an aluminum crush washer. The plastic heat shield protects the injector nozzle and it's slid on first, then the crush washer. Once the injector clamp bolts are torqued, the washer should spread and hold the heat shield in place. You should install the heat shield as it protects the injector. I hope this helps, Regards Andreas

[@normanboyes4983]

That was a very comprehensive and competent rebuild and very well explained. I am intrigued though with a couple of things, (1) Your use of grease rather than engine oil on reassembly. (2) Torque figures are normally quoted for dry threads, yet you greased/oiled some torqued fastenings - would you care to comment? Nice work.👍

[@user-jg6bd7se8u]

Another banger! Andreas you make some really nice videos! I really like how you show the info specs too. So glad I found this channel, thank you for sharing!

[@WorkshopRebuild]

Thank you so much!! I try to make the assembly videos as easy as possible to follow and torque-specs are usually a pain to find online...unless you have the manual in front of yourself. You're always one of the first to comment and your support means a lot! Thank YOU!!

[@al4407]

Hello a very perfect work here you can see a lot, I have another question I have a 3TNE 74 with dismantled (not dismantled by me) defective cylinder head, have now got a good used one but how do I put it on, that the timing fit because I do not see the position camshaft greetings Andy

[@WorkshopRebuild]

Hi Andy, thank for your comment. The cylinder head can only go on one way due to the pushrod holes. The timing does not happen on the top end of the engine. This is done between the crankshaft, idler and camshaft gears. On the top end of the engine, you only need to focus on the rocker arm assembly and set the correct valve lash. Cheers

[@TheEcoClimber]

Very useful, as this is similar to the B50 Yanmar digger 1989- 1998 engine 4TN88L on the excavator- cheers

[@WorkshopRebuild]

That’s great to know! I hope this video will provide you assistance. Regards Andreas

[@lesnicholas2433]

Brilliant video,I have a 4TNV88-D in my boat it’s currently on 4456hrs still starts first time every time never took a spanner to just service religiously.Great to see what they look like inside 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧Cheers 👍

[@WorkshopRebuild]

Thanks for watching and leaving a comment! Your Yanmar engine is treating you well and that is a fair amount of hours, but then again if serviced regularly they should last a long time. Regards Andreas

[@bobbyjmcguire6448]

I have a broken 3tnv82a, I came across a 3tnv88f. Stupid question, is it possible to bolt this into my jd 3005? I mean, could these engine be made interchangeable?

[@WorkshopRebuild]

It's very unfortunate to hear that your 3TNV82A gave up! I am not familiar with the JD and have never worked on one before, but I just did some research on it. The biggest different between the 3TNV82 (A) and a 3TNV88 (F) is the displacement. You'll be going from a 1.3L to a 1.6L, but I believe your manual transmission should be able to handle that. On the other hand, the 3TNV88 (F) is a shade larger size. Here I found a pdf file that shows the dimensions on the last page: www.yanmar.com/media/news/2019/12/10074714/tnv_series_201912.pdf Not only should you take this into consideration, but the bolt pattern of the bell housing. This could be off by just a bit and you won't be able to merge it to your tractor... With that said, I would highly recommend you reach out to Yanmar and ask them this question. They are usually very helpful and they can steer you in the right direction. Even if this is for your own personal project. I hope this helps. Regards Andreas

[@scgoralski]

Awesome video, thank you! So helpful as I have my Yanmar engine to rebuild and this fills in so many gaps. Cheers

[@WorkshopRebuild]

I'm glad I could share this video with you. I hope your engine rebuild will be a success! Regards Andreas

[@yurikgrusko]

Hello, can you please tell me what is the tolerance for the piston offset in relation to the block, the cylinder head after repair, the block was lined and removed 0.18 mm, when installing the valve gaskets they meet the cylinder, on the first and 4th cylinders, I measured the piston offset from the block to be approximately 0.20 -0.25 mm

[@conebone669]

Would you be willing to restore my John Deere 430? I’ve lost interest in the project, but would love it fully restored.

[@WorkshopRebuild]

Hello Curt, thank you for leaving a comment and inquiring about a restoration project. At this current moment I do not have enough time to accept work outside of what I share here on KZbin. This is very unfortunate, as I receive this question on a daily basis in my emails, on social media platforms and here in the comment sections. Maybe there is a mechanic or JD enthusiast near you, that would love to take on the rest of your John Deere 430 project! There are multiple Facebook groups you can join that talk about John Deere garden tractors on a daily basis. I have a good feeling someone would take on your project for you. Regards Andreas

[@brianquade1460]

Hello, thank you for posting this video!! I have a 3TNA72UJ that I am in the process of having to rebuild. Do you know where I may get a rebuild manual? Have you any videos on one of them?

[@leroyterrell7367]

Question what would I have to do for a 3tnv82a bottom in to work with a 3tne82a head?

[@WorkshopRebuild]

I wouldn‘t be able to tell you that! Maybe you can contact Yanmar directly and they can give you a heads up on what to look out for. They answer technical emails very well! Regards Andreas

[@asareedmund7566]

hello please wanted to ask if I could change my 3cyl engine to 4cly engine without encountering any problem.

[@WorkshopRebuild]

I‘m not sure how you will add another piston to this engine, because this is strictly a 3 cylinder engine. This engine was produced in 4 cylinder version.

[@efrainhuerta1585]

I understand timing gears A B and C how did you time injection pump shaft with key to gear.

[@WorkshopRebuild]

The injection pump shaft has a key and when you remove the gear it can only go back on one way. This means when you put your gear back on, the timing is already set between you injection pump to the timing gear and the timing gear to idler gear. According to the factory specs. you should never remove or adjust the 4 bolts that are holding the gear to the flange. This adjustment should only be made in the factory to set the correct position of the gear to the injection pump. I hope this helps. Regards Andreas

[@bud1141]

I have a Yanmar YB10 mini-excavator with the 3T72L-TBS engine in it. Can you tell me where to a service manual for the engine? I’ve looked everywhere that I can think of. Thank you.

[@WorkshopRebuild]

Hi there! I've been searching the web for your exact engine series and I haven't come across any service manual that corresponds with your engine. The TBS part is not really necessary, but the base engine manual would be sufficient, as your engine comes in different variations. I hope you find a service manual sometime soon. Regards Andreas

[@bud1141]

@@WorkshopRebuild Thank you very much for your concern and effort.

[@mannyencarta1961]

Why not buy a short block?

[@tomasmurza4914]

What is the best way to remove the thiny cylinder sleeves from such a Yanmar 3 cylinder engine block?

[@WorkshopRebuild]

Hi Thomas, these cylinder sleeves are not factory original! They have been installed by the machine shop, in order to repair the (used) engine block.

[@tomasmurza4914]

Thank you

[@stewatparkpark2933]

The rocker shaft mounting bolts can be one time only use stretch bolts on those small Yanmar engines .

Good comment! 👍👍

[@roymorgan5498]

Thanks for a great video.👍 Makes me wanna go out and find a motor to rebuild. Lol! We had a problem with our John Deere at work with motor bogging down on inclines. Coworker put new fuel filter and a electric fuel pump and it still bogged down. Next day I came in and figured it out.....was the suction line screen in fuel tank had sludge covering it. Now we can cut grass on the hill. If motor was need of repairing your video would of helped me. Thanks again. ✌️

[@jefflburton1960]

What position do the pistons need to be in when aligning the gears?

[@WorkshopRebuild]

The pistons are already positioned once the crankshaft timing gear is placed on the crankshaft. There is no way you can mix this up.

[@bobjack9905]

@@WorkshopRebuild I have the 3tn72 and had the #3 piston at TDC when I aligned and installed the timing gears. Am i to assume the position of the crank doesn't matter as long as all of the marks line up/ Bob in VT

[@theman63devil6492]

Is there a difference in the valve springs i took 2 of them off not sure if there the same or different i may or may not have them mixed up

[@theman63devil6492]

Also wad wondering why you only installed one Camshaft bearing mine looks to have 3 spots for bearings and it only has one cam bearing on the front

[@WorkshopRebuild]

On this engine they are equal, so it shouldn't matter where you place them.

[@WorkshopRebuild]

Correct, the camshaft is held by three plain bearings within the engine block. The only reason why I replaced the front one was due to wear. The other two were perfectly within spec and had no imperfections.

[@theman63devil6492]

@WorkshopRebuild ok thanks reason why I was asking is mine is missing the back 2 I was like that's not right and the kit I ordered has 3 I watched your video and saw you replace just the front I was like maybe he knows something I don't . thanks for the reply I appreciate it.

[@bos2525]

Hi, whats the name of the washers you are adding at 37:16?

[@WorkshopRebuild]

The washers you're referring to are called VALVE LASH CAPS. When properly matched, valve lash caps provide an increased path for your race engine's roller rocker arm nose roller to glide back and forth over. This prevents the rocker arm from getting too close to the edge of the top of the valve tip, which will result in damage to both the rocker arm and the valve. I hope this helps. Regards Andreas

Is it possible if you can try to get a engine 3012 yanmour engine to rebuild. Diesel

[@WorkshopRebuild]

Hi there, thank your for your inquiry! Most of the time I repair engines that are out of a vehicle or a piece of equipment and unfortunately I do not have the ability to just find a specific engine for a rebuild. Up until this day I have rebuilt two different Yanmar diesel engines (3TN75RJ & 3TNV82A) and both videos are on my channel. Since most Yanmar engines are the same, you can definitely take away something from both videos to assist you with your repairs. If I ever work on any other Yanmar diesel engines, you'll see that on my channel in the future. Thanks again for your comment. Regards Andreas

Great video, thanks for making it. I love this engine so much. No plastic! Even a 100k new truck has a plastic oil pan, plastic intake etc. NO timing chains either! Reliable as hell

[@WorkshopRebuild]

Thank you very much for your overly positive comment! I really like this engine too and all the features you listed make an engine last that much longer. Nowadays some engine components are only meant to last a certain period of time. I guess we have to live with that...or just buy an older piece of equipment haha. Thanks for watching.
