- After dismantling the John Deere 1445 engine it was clear to me that this little 3-cylinder engine needed some love and a few parts! Luckily I found a supplier that had exactly what I needed.

With this engine rebuild kit, I will be able to send the cylinder head and engine block off to the machine shop. They will go through the head and make sure it receives brand new valve guides, valve seats and it will be decked.
The engine block head gasket surface will be machined and then the machine shop will install sleeves into each bore. Once three sleeves have been installed, they will bore them out once more to accomodate the original size pistons.
Once this procedure is done, I can pick up all the parts and look forward to an engine assembly!

Sorry for not being able to help you find a brand new oil pan extension, but so glad the used one met your expectations! Thanks for such a detailed and professional video. Merry Christmas!🎄
No worries, like I mentioned in this video the quality of your used part is amazing! I cannot wait to assemble this engine once it comes back from the machine shop! Merry Christmas to you and your team! Regards Andreas
Thats a really nice looking rebuild kit you put together for him
Friday parts is GREAT , They sent me parts for my Landcruiser , Kinda Sucks i did not make Many videos of it..
But will be doing that soon!
I fully agree! That's right they also supply car parts too which is a huge deal and I'm glad you were able to find parts for your Landcruiser. I'll check your videos out tonight. Thanks for your insight -Andreas
Thank you. Looking forward to your videos☺
Small tractors with limited 12 pto hp would be great if you could speed the the pto rpms up to 3600 from 540. Then smaller accessories with worn out gas engines could be run by the diesel. Figure two speed increasers in series would jump the
540 to X to 3600 (1 to 7 ratio overall). Also remove rotation reversal at final.
Just the $1000 of hardware to overcome now.
Hi Tom! I‘m not exactly sure what rpm you‘re trying to achieve with your 12HP engine.
Usually tractor PTO speeds are regulated at 540RPM or 1000RPM. For small garden tractors this isn‘t the case, but to let you know there are probably no attachments that run at 3600 RPM.
At the end of the day, you‘ll need to reduce your gearbox, because most work is done at mid- to high RPM‘s or the tractor engine.
Please let me know what you‘re intending to use this high rpm speed for. I‘m really curious!
Hello! Please tell me the thickness of the cylinder head gasket.
The overall thickness measures in at 0.65mm. This headgasket is two-ply.
I hope this helps!
Why do you need to bore down? What 0.025 inch? Or can you order undersized pistons to solve that issue? I was thinking standard size rebuild would fit the OEM machine
The bore of a used engine block is always larger in size due to wear inside the cylinder bores. With this in mind you cannot install original sized pistons, as they would be too lose within the bore.
In this case you can either bore out your cylinder to the next size "OVER", or choose to install dry sleeves.
When you choose oversize pistons, you purchase pistons that are larger in diameter, to fill freshly machined cylinder bores.
For example if your OEM bore is 82mm (3.228"), the pistons you can choose are usually +0.635mm (0.025") and +1.27mm (0.050"). This gives you a choice of pistons at 82.625mm (3.253") or 83.27mm (3.278").
If you decide to go back to the original size, your must machine your block, install sleeves and re-bore the sleeves to the OEM diameter. Then you can install your OEM diameter pistons.
Either way, you must always install new pistons and rings in machined bores. Now if you want larger pistons it's cheaper, because less machining is involved. If you choose to go back to the OEM spec, you're paying for double work.
***Keep in mind, these numbers are just an example for this engine and all manufacturers have other specs/tolerances for their engines.***

@@WorkshopRebuild ok thank you for the response. I was thinking the original engine came with a removable sleeve. So if you replace the sleeves and run new standard pistons in new sleeves... doesn't fit? doesn't work that way? My application is for a very similar engine to yours. From an excavator B37 Yanmar 3TN84L. I think it's also in the 870 John Deere tractor. Correct me if I'm wrong, the updated version of this engine would be, 3TNV84L? Besides adjusting some stuff for emissions compliance, is the new TNV engine any different from my older TN engine? Would they fit exactly the same? Same dimensions? Thanks for helping!
No Yanmar 3TNV engine comes with removable sleeves!
Wet sleeves or some call them wet liners, are inserted into the engine block. They are machined from a different type of alloy than the engine block, which makes manufacturing the engine a little bit more expensive, but very easy to repair. These types of sleeves are sealed with o-rings on the bottom of the sleeve and towards the top, holding water within the coolant passageway.
The other type of sleeve is a dry-sleeve. This sleeve is a machined part that is inserted into an existing engine block (only for repair purposes)! This sleeve will never come in contact with the coolant, hence the name dry-sleeve.
The Yanmar 3TNV84L has more displacement than some of the Yanmar engines I've previously worked on, but it's VERY similar! I cannot tell you exactly what Yanmar changed when they went from the 3TN to the 3TNV engines. I found a great article that might help you understand more about the 3TNV engine family and it will assist you with your engine dimensions: www.yanmar.com/media/news/2019/12/10074714/tnv_series_201912.pdf
I hope this will help you out. If not, you can always contact Yanmar directly and I'm sure they'd be willing to help you answer some questions. Cheers
I have this code on engline block 3D82AE and on plate from valve cover i have 3D82A-3FAE ( this engine is on komatsu excavator) can someone tell me witch is the corect cod from yanmar ?
Valve cover number👍🏽
@@WorkshopRebuild Thank you, can you tell me by that code if my engine is an tnv or tne ?
In the scheme of things how does the wear on this engine compare to the small amount of wear on the old BMW R60/5? I've checked back on the mileage/kilometerage and the BMW had done 90 000 km. Roughly how many kilometers has the Yanmar done?
This engine has far more wear within a shorter time period compared to the BMW R60/5! This engine came out of the John Deere 1445 and the digital hour meter shows just over 1000 hours. On industrial equipment you'll usually find hour meters instead of odometers, because a lot of times engines are idling or doing work with attachments while being stationary.
Nowadays with digital hour meters, it starts ticking when you turn your key over and that means it actually doesn't correspond with the engine hours...or at least on the John Deere 1445 I have here!
Back in the day hour meters were mechanical. They were driven by a cable and all engines had a rated speed for 1 hour of time. For example: Rated speed 1500RPM = 1 hour time. This means if your engine was under load at 3000RPM, you would have seen 2 hours of elapsed time on your hour meter.
With all of that said, there are so many factors to take in consideration, especially with a digital hour meters. 1000hours to me is a VERY LOW HOUR MACHINE and it's hard to tamper with a digital hour meter. I would say this tractor has done maximum 30'000km (1000 hours/ 11 years = 90 hours a year or 30'000km/ 11 years = 2700km a year).
I think this is a very honest evaluation, but you can really tell that something went wrong with this engine in a short period of time! The BMW on the other hand has stood the test of time, but the cylinder bores will be machined to accomodate brand new oversize pistons. More on that in an upcoming video.
Thanks for another great question Simon! -Andreas
@@WorkshopRebuild Thanx for a thorough and comprehensive response Andreas.
what made you want to get a used john deere 1445 not that it's bad I'm just curious because I think the 1445 is better then the newer 1585.
Hi there! I've never been in a JD 1445 before nor in a JD 1585...so I can't say I purchased this because I always wanted one! You probably have much more experience with these machines than me. Honestly, I found this one at an auction and the price was just too good to be true, so I decided to get it. It'll be interested to see how this machine performs once it's back together and running.
Do you own a JD 1445 too?
Regards Andreas
@@WorkshopRebuild no I don't sadly I'm trying to get a 1445 for my lawn service hopefully soon but yes despite that I do have a lot of experience with these things I mean I could never do something like this but I do have a lot of experience operating these things and keep in mind I'm only 17 so the only experience I have that even comes close to what you're doing is with smaller lawn mower engines and fixing filter queen vacuum cleaners. in the future I would like to try to do something like this.
Hey man, I‘m glad to hear that you‘re already trying to level up your equipment!! I can‘t tell you right now how good the JD 1445is, because it‘s not running yet, but I‘ll have a review about it in the new year!
Your first fixes are important, especially on small equipment. Once you know all the ins-and-outs, you can upgrade or even take on a new project.
Enjoy the process! Cheers😃👍🏽
@@WorkshopRebuild thank you btw you will not be disappointed with your 1445 these are great mowing machines
