Thank you Matthew, I always try and keep everything clean. Many aspects of this engine rebuild will be similar to other engine rebuilds and if you have any questions let me know. Cheers
I have a Yanmar 1601 D tractor and according to my research my tractor has the same engine the 3T75U. I just had the head gasket replaced on my tractor and in the future this video will really help when I rebuild the engine. At the moment, my tractor only has 630 hours. Thank you so much for your detailed video!
I'm so happy to hear that you choose this video to assist with your Yanmar repairs once you rebuild it. Usually these engines are bulletproof (when taken care of), and they will last for a very long time. A nice thing about these engines is that they are in various types of equipment, so most Yanmar engines are very similar in performance and compatibility. This makes it just as easy to find parts if needed. Thanks for your wonderful comment. Regards Andreas
holy cow! The detail and explanation of the process is well delivered! Great idea using the yellow marker on the wrist pin bushing oil port!! Unbelievable the level of detail, I can't say that enough! Great job
Thank you very much! That's the first time I used the yellow marker to line it up like that and it worked really well. I always try new ways to make things easier on myself and try to share that with everyone. Thanks again, your support and feedback means a lot!! Regards -Andreas
I hope this helps you out Omer! Here is my newest Yanmar diesel engine rebuild video, if you want more information: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eEIzlKw-aRg.html&lc=UgzQWsKJjyaMmcHc2zJ4AaABAg
Thank you very much! I brought this to a local machine shop to me in Edmonton, Canada. I hope this video will help you and if you need more information, you can always check out the Service Manual in the description of this video. Regards -Andreas
I installed my timing marks with the #3 (closest to the timing gears) piston at TDC. If all of the marks are properly aligned, would this matter? Bob in VT
Hello! Thanks for this terrific video series on the JD 855. I'm refurbishing one right now starting with the tired 3TN75RJ. Two questions: I'm not familiar with FridayParts. Have you found them to be a good retailer in terms of accuracy, shipping time, etc.? Did the injection pump need anything other than a cleanup, fresh oil and setting of the timing? Did it have any leaks or other issues? Thank you.
Learning more and more from your play lists I am reviewing. Have a Gator with the smaller Yanmar 3TN66 so your JD 855 engine's rebuild is a God sent. Have notice important differences in small diesels. My 1986 Kubota B7200 compact tractor uses a Kubota D950 engine. Kubota installs dry sleeve in factor before installing engines. If cylinder wall gets damaged bore out old sleeve and install a new one. Yanmar uses engine block for first cylinder wall and dry sleeves later if engine is rebult. Seems Kubota can use milder cast iron for block than Yanmar? Any insight as to any advantage either way? My kubota has a 20 second glow plug heatup before engine start. The Yanmar 3TN66 has only a 5 second preheat. Hope you can explain that to me. Is it just different glow plugs? Good topic to cover. Tom
I'm glad you can find value within the videos I share! It really makes me happy to hear this. The Service Manual shares details on your engine as well (Link in the description). You got that right! If Kubota uses milder steel during the casting process, they might be able to cut costs. Now when it comes to machining, their machining process is probably dialed in that they can "Sleeve" these engines within a couple seconds. This is achieved by a well-structured machining plant. Kubota probably produces "New Sleeves" and "Rebuild Sleeves" to the same size, which will same them a bunch of machining-time and material cost. Yanmar must have had a larger cost upfront for the engine block, but they do not have to deal with the dry-sleeve method. This really depends how they set up their factories for not just one engine model, but for hundreds of models! Small changes to a mass production runs can cost millions!! I had a look at the glow plug models and they seem to be exactly the same for both engines. On the Yanmar engine I have here, they have the extra air intake heater. Maybe if your Kubota ONLY has glow plugs they recommend 20 seconds and if your Yanmar has glow plugs and an air heater you can get away with only 5 seconds of glow plugs. These are my thoughts so far, but maybe you have figured it out by now. I hope this helps and thanks for another engaging comment! -Andreas
Perfect video, so well explained! Unfortunately I see link to service manual does not work in you description, any way of sending it to me? I'm repairing a Yanmar F17 with similar engine but can not find any further info online... thx a lot!
Hello Frederik, thank you for your valuable feedback! I checked with three different devices I have at home and all seem to open the link just fine! Here is the direct link and you can let me know if this works for you: golftechs.us/Manuals/JD220dieselengine.pdf I tried to find information on a Yanmar F17, but I did not find much. What machine is the F17 in? Maybe that will help with my search. I hope this helps you out. Regards Andreas
Very informative and excellent quality video that is greatly appreciated as I am currently assembling a 4TNE88. Do you have a procedure for fine timing of the injector pump inward or outward and alignment with the flywheel timing marks if required? Thank you!
Thank you for your positive feedback and I'm happy to hear that you're taking on your own Yanmar rebuild project! I do not have a video discussing the injector to engine details. All engines usually have a different degree of fuel injection and some even have a different pumps. On Yanmar engines you inject fuel anywhere between 12-18degrees BTC. You should also verify this with cylinder #1, closest to your flywheel. After that all cylinders should be timed. I hope this helps. Regards Andreas
Sehr gutes Video! Wie von dir gewohnt tolle und lehrreiche Präsentation👍 Da wir den selben Beruf gelernt haben wundere ich mich, woher du all das Wissen hast 🤔 Es muss daran liegen, dass ihr in Rüti deutlich bessere Ausbildung hattet als die welche wir in Rapperswil erhielten😂 Gruss und weiter so…
Vielen Dank, Ivan! Ich versuche immer, meinen Zuschauern so viele Kameraperspektiven wie möglich zu geben und genügend Informationen für jede Baugruppe zu teilen. Das ist richtig, wir hatten die gleiche Ausbildung! Ich versuche einfach immer, so viele Informationen wie möglich aufzunehmen und wenn ich etwas repariere, sollte es funktionieren (Daumen drücken)!! Die Schulen auf beiden Seiten beschränkten sich auf das, was sie uns wissen lassen wollten. Gut oder schlecht, ich weiß es wirklich nicht HAHA! Gruss -Andreas
Am I able to replace my crank bearings from just the bottom end without needing to remove crank and pistons. I have the yanmar 3tna72uj. Thanks again for all the great info
Hi Scott, in order to access or remove the main bearing caps, you would have to remove the oil pan extension (plate between oil pan and engine block). I believe it should be possible, but you will need to support the crankshaft in a way so it does NOT drop down on you. Maybe you can loosen off all main bearing caps and replace each bearing at a time. Before you losen off any of the bolts holding the main bearing caps, be sure to make a mark with a pen across the crankshaft gear and idler gear. This way you will know the timing (VERY IMPORTANT). I hope this video gave you a little insight on how it can be done and hopefully you will manage to get the repair done! Regards Andreas
Hi there! Thank you for your kind comment!! In the description of this video you will see a link right next to "Yanmar Engine Service Manual". This service manual covers basically every Yanmar 3TN and 4TN engine. I hope this helps. Regards Andreas
Hi Richard, thanks for tuning in and it‘s nice to hear that you have a similar John Deere Tractor! If you‘re not receiving fuel to your injectors I would suggest you check and see if your 12V inline fuel pump is working, check your fuel filter and bleed your system. In this video I went through my startup process and maybe you can find some tips that will help you: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rvqs3cMLSik.html Adjusting the timing of the pump will not supply you with fuel. Adjusting the injection pump will allow you to fine-tune WHEN the fuel is injected into the combustion chamber. This has nothing to do with a constant fuel supply. If you have any other questions let me know. Regards Andreas
Hello Mark, you are more than welcome and thanks for tuning in. The diesel injector part number according to John Deere is MIA880416. On this website you can view the parts drawings if you wish: bit.ly/39aUhVI I hope you get your JD855 running properly again! Regards -Andreas
If you don't mind me asking how much did this rebuild roughly cost? I have a 3tna72uj2 engine in a john deere 430 that I will most likely rebuild soon. I am curious on the kit cost for an idea on mine, along with the machine shop total for all that work also
Hi Jordan, thanks for asking this question! The engine rebuild cost came in at around $1700 CAD ($1250 USD). You can find the total rebuild cost at tractor cost breakdown in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wRjN7DoHhvw.html The prices can vary heavily, depending on how much work you do yourself, how much the machine shop charges and how much your parts will cost. I hope this will help you out to get a rough estimate for your own engine rebuild! Regards Andreas
Hi, Your video is super. The part I want you didn't cover. The injector heat shield and seal is NOT listed in John Deere's 855 catalog. My engine does have these. Does John Deere figure these are not needed? If you can find these seals please let me know where you got them. Happy Trails, Daniel Lindberg
Hello Daniel! Thank you very much!! In Part 7 of the John Deere 855, I mentioned that I a missing one injector bracket and all three heat shields, as well as the spacer/washers for the injectors. I should have these in the upcoming days and I will let you know where I ordered them in an upcoming video, or you can E-Mail me if you would like. Regards Andreas
@@WorkshopRebuild Hi again, Dan Lindberg here. GUESS WHAT!!! I found the heat shied and seal in the John Deere Parts catalog PC2054 under 20 engine, 26 cylinder head and gasket, idem 7 guard M810460 and idem 8 seat M801017. They weren't listed with the fuel injector where I thought they should have been. I sure enjoy your video. Happy Trails, Daniel Lindberg PS By the way if you're wonderin' .I live in Wilcox, Pa.
@@daniellindberg8256 Thank you for sharing this awesome update! I found a supplier for these parts and got them in the other day. In my most recent video I shared a couple details on these parts and now I'm waiting for an injector shim kit to finalise everything. I appreciate your comments, as this will help others in the near future as well!! Enjoy your weekend in Wilcox, PA. Greetings from Alberta, Canada -Andreas
Great question! I do not have any concerns about the quality of this rebuild kit. Once I received all the parts and before I even made a video I double checked all the sizes of the sleeves, pistons etc. My local machinist that bored out the sleeves for me also told me that the material he machined was very good. Up until now the tractor has been running strong and it'll be tested more in the winter time, when I start to clear snow with my freshly rebuilt snowblower. I hope this helps! Regards Andreas
Thank a lot! When I checked the specs in the manual they seemed far too small. Many times when I gap piston rings, they tend to be larger than this and that's why I had to review them more than one time. With the rule of thumb (~0.004" end gap per inch of cylinder bore), you really can't go wrong. This is a very common size for naturally aspirated engines. If you add more fuel, turbos or even superchargers, you want to open up your end gap a shade to deal with temperature differences at higher rpm's. What values did you find in your manual?
@@WorkshopRebuild It shows: Piston Ring End Gap 3TN75 Compression Rings and Oil Ring Standard . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.20 - 0.40 mm (0.008 - 0.016 in.) Wear Limit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.50 mm (0.0591 in.) Right above that is piston ring groove clearance which matches the numbers in the video but in mm instead of inches. But your rule of thumb falls right in the middle of what is called for so that's good to know. Thanks
Thank you for your response! These values are indeed different than the ones I found in that online service manual! I'm glad I wasn't off with the piston ring gap! If the values are too small I always try to double-check them online, but I did not find any other information...even though these engines are very common in older pieces of equipment. Once again, thanks for your input and hopefully your comments will be seen by others just in case they would like to verify the correct values. -Regards Andreas
Quick question did you use OEM pistons and oil rings? I noticed the Friday parts pistons and oil ring specifically the expander spring are different and what you show in the video appears to be OEM?
Hi there! For this Yanmar diesel engine and the 3TNV82A engine rebuild, I only used parts from Friday Parts. Usually, these parts are stamped with the corresponding engine and if they are not, you might have the wrong parts. Feel free to send me an email with a picture of your pistons & rings. (wprkshoprebuild@gmail.com). This way I can tell you if you got the right stuff or not. It's also worthwhile checking in with Friday Parts just to be sure. Regards Andreas
@@WorkshopRebuild Great thank you so much I think I see the discrepancy but I will definitely keep your email as I am currently in the process of rebuilding a 3TNA72L. Also great video
I am rebuilding a John Deere 955. It has 3TN84-RJ. The motor dropped the #2 cylinder. I found oil mixed with fuel in the fuel filter bulbs. I would like to rebuild the injector pump . Do you have any material on how to do that ?
Hi there, thanks for asking such a great question! Up until today, I have not rebuilt or sealed an injection pump on RU-vid. Unfortunately, both Yanmar engines that I have rebuilt so far have had good injection pumps, and therefore nothing had to be done to them. I'll try and find a service manual for this injection pump that might be able to assist you with your repair. I will get back to you by tonight. Regards Andreas
Hi Scott! If you want the oil to return to the oil pan, you can route this to the timing cover. The gears internally are lubricated and allow oil to drain back into the oil pan, through the oil pan extension. I hope this helps.
Hi there, I wasn't able to find any information about your 3T75 engine online. Your best option is to send an email to Yanmar to ask for this specific bolt torque. I hope this helps. Regards Andreas
Thank you very much for your feedback! I try my best to find generic music and it's not always easy. I hope to improve on this in my upcoming videos. Thanks again, Regards Andreas.
Hi there, the engine rebuild cost around $1700 ($1250USD). You can find more info on the breakdown in this video: This John Deere 855 Cost Breakdown ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wRjN7DoHhvw.html Regards Andreas
Hi do you maybe know what is the best oil for those engines, i have 3 cylinder engine in 1,6 ton excavator i live in croatia in winter temperatures sre oround 3-15and in summer 22-38•c thank you
Hi there! That's a great question. I usually opt for 15W-40 even though I live in a cold climate country, like Canada. You will find this works even better with your temperature range! I hope this will keep your excavator up and running for many more years. Pozdrav Andreas
Thank you can you please make video of how to check engine oil pressure i think it will help many amd have lot views, amd can you please tell why my engine smoke on iberlauff(the hose taht goes from top gasket) it domt loose oil and oil is new thank you🙏
I am in the process of acquiring a JD855. I'm searching the Web looking for any and all resources I can find to learn more about what to look for when purchasing this tractor as well as what it takes to maintain it. Your videos are awesome. Thanks for all the detail. TOP SHELF STUFF HERE!!!
Hi there! Thank you for your kind comment, it's much appreciated!! There are other videos out there that might offer more help for servicing, but I hope I was able to share enough information around the engine specifically. These tractors are very robust and if your drivetrain is working as well as your PTO, then you already have an awesome machine. If you have any questions feel free to ask and I'll try my best to give you an answer. Regards Andreas
Hi there! Most 3 cylinder Yanmar diesel engines are timed the same. You can see me time the 3TN75RJ in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JYa-o0gZiyA.html around the 34:29 minute mark. I hope this helps! Cheers
Hi, gerat video, thanks! @25:30 you mention the service manual in the description, but i cant find it. can you help me? Where do you find detailed service manuals, with explosions views or installing description online? I have a Yanmar YB351 excavator with a 3T84 HTL -BS engine and the cylinder sleeves are done... So i am looking for replacement parts online, but they don't provide much information on their products. Thanks
Hi there, I already got this question asked before and the service manual is in the description of this video. I have since changed it to the second link in the video description, but here is the link for easier access: bit.ly/38rImT3 . Let me know if you were able to open the link, because it is an online pdf (which can take long to load). This service manual will share everything from the disassembly to the assembly process and share vital information of most components. There is a chapter about the 3TN84 engine and that should be very similar to your engine. Maybe the pictures and measurements in this manual will help you confirm this. As for parts, you can find them here: www.fridayparts.com/catalogsearch/result/?q=3t84 This company has been my best source of parts lately and I can rely on their staff when technical questions are involved. Check them out! If you have any further questions feel free to ask. Best Regards Andreas
Hi there, I am not familiar with the Kubota BX series, but I have rebuilt Kubota V engines before. They have thrust bearings and are realatively easy to replace if that needs to done. Regards Andreas
@@WorkshopRebuild im having to replace all main bearings crankshaft gear oil pump and there's no video out there on this particular tractor engine I didn't see any thrust bearings on it unless they are made into the main bearing But there was no sign of them I was hoping I could find whether they either disintegrated or they weren't on in the first place
I fully understand! It's not always easy to find the right video or info on a specific make or model. Most Kubota V engines are very similar, just different size pistons and shorter/longer stroke. The bearing kit here: www.fridayparts.com/metal-kit-for-kubota-d902-engine-main-bearing-con-rod-bearing-thrust-washer?gclid=Cj0KCQjwoK2mBhDzARIsADGbjeqXFt-y65eUJkOJiN9NMDN3pZQLGdstMbpNqxFOKyUH1yeGyBky4rUaAsCyEALw_wcB shows you what the thrust bearings should look like. If they are shaped like this, they should be seated on either side of a main bearing cap and the engine block. If you can't see any, then they were not installed...which is not a good thing! If they completely wore down, then you have maybe a bigger issue. Since your tractor is hydrostatic, there shouldn't be much load on the thrust bearings. If there is, then your engine alignment is way off. Let me know if you find a solution. Regards Andreas
