- Change the hydraulic fluid and 2 filters to service your John Deere hydrostatic transmission. Models include 345, 335, and 355D. Procedure is the same for other models as well. Be sure to check for the correct filters for your tractor. I hope this video helps give you the confidence to Do-it-Yourself!
1 Gallon JD trans fluid - amzn.to/2PCakgC
1 Quart JD trans fluid - amzn.to/2ofeKOg
Filter AM120916 - amzn.to/2oecfM7
Filter M806848 - amzn.to/2MvYTJz
Thanks for watching.

Where was the oil leak that put oil all over the transaxle? You power washed it but never spoke about the source of the oil leak.

I just serviced my 345 and the transaxle was just as dirty and oily as the one he serviced. I believe the source of oil is from a vent cap right above the yellow oil fill plug. Trans gets hot during use, vents hot air with some oil particles and over time coats everything with an oily dirty mess. I didn't get anywhere near 5qts of oil out.
@@mitchy880 Sounds logical - I think that explains the oil leak - actually was vented oil only.

Currently negotiating a deal on a x 738 and this video helped a lot. As a result I "liked" the channel and have subscribed as well. Wish you the best and look forward to more of your vids.
Thank you so much, Andy!
I always pull the rear cover/seat off and clean everything like you did. I put the belt over teh transmission fan first. I pull the two idlers after I take the drive belt tension spring off by hand. Removing the idlers helps to determine that they are in good shape and gives you lots of freedom to route teh belt. Putting the tensioner spring back on, I hook the end on the moving pivot lever and use a very large screw driver to pop/lever the spring onto the crossbar anchor point. It is pretty easy to do. The ratchet strap works too, just slower.
Thank you for the recommendations!
My John deer is doing the same thing . looks easy enough don't have a husband to do it so I might try I can watch your video as I go. Thanks for the video
Sounds good, Linda. Good luck!
At 11:00 in the video you can see that the belt is worn and almost broken in half in some spots. It would be a good idea and pretty easy to replace the belt while you've got the tractor disassembled and the belt exposed.
Yes, agreed. Thank you
One of the best how to videos on the net... thanks so much !
Thanks for watching and commenting. I appreciate the kind words.
Great video and explanation! Thanks!
Perfect video.....showed me everything I needed to know....how to-what wrenches....part numbers...Chose to subscribe to your channel....thanks so much...too poor to hire a mechanic
Feel better taking on this job now. Thank you.
it is not a hard one and the most expensive parts are the filters. I forget how much they want for them but the green one is expensive. It is recommended that you use John Deere Hygard or at least a GOOD hydraulic fluid if you don't use that one. Don't get that twenty dollar a bucket junk. As for that internal filter, I am not sure who makes those for John Deere but a lot of things like that are often supplied from someone else. If you don't plan to do that green inline filter it gets easier because all you have to do is take a wheel off to get to the drain easier. You might be able to do it without taking a wheel off but I don't know what that oil would do to the tire, it would probably ruin the tire. I like watching other people do these kind of things myself. It just gives me a better idea what I should expect when I get started on it.
This video helped me out quite a bit. Thanks for making it!
Great video, I was going to take my mower the John deere until I saw how simple it was to pull the rear cover off. I have a gas leak I can't see because it is under the cover. Thank, Now I can work on it my self . Excellent video.
Thank you, and good job doing the DIY thing!
Thanks for the great video. This will make it easier on my 325.
Hey, that's great. I love learning new stuff on youtube, and I'm glad my video was helpful to you! Thanks.
Thanks for the video. I will be tackling this job later today.
Thanks, Sherry. Hope it works out well for you. The cost of the filters and hydraulic fluid was a surprise to me. Out of curiosity, does your tractor still have the engine hood? Plastic engine hoods was not a good idea, in my opinion.
Yes, everything went well. I do still have my hood and its in good condition. I am missing a piece of molded plastic on the left side at the front of the tractor where the snowblower attachement connects. I have priced it out and have decided I can do without it. Too costly.
It would help to provide the year & make of transmission serviced. I have a JDx350 with Tuff Torq K46.
Thanks for the vid. The owner's manual says there are two drain plugs, one on the differential side and one on the hydrostatic side... but it also shows the fill port somewhere that doesn't exist on the machine. Was there another drain port?
Wow, I really can't remember if there were two drain plugs or one....been quite a long while since I did that job....
Great instructional video! Hookem Horns!
I’m thinking it’s just not that hard to do this: my thinking over the years was it requires special tools because the manual only speaks of the dealer doing this task. You would think they would prefer customers do this, get in over their head with this project and they could ultimately charge more. Thanks. I’ve got an x324. Is it similar enough to somewhat use yours as a Chinese blueprint. Besides the part numbers of course? One more question. If the mower is having a problem going up hill that’s probably related to the transmission? I can audibly hear it and really slows down and sometimes just seems to run out of energy...
how did you get the bolts off to take the fender off?
Very well done sir.
I find that removing that filter on the bottom seems to let most of the fluid out. I took it out first once and that is how I found out. I did have a catch pan ready. It looks like a rather odd size filter being long and narrow. I am not sure who makes that filter for John Deere but I had a Cub Cadet and its transmission had a Donaldson filter. I hear that is a good brand. It would not surprise me if John Deere's filters were also Donaldson. My Cub Cadet didn't last long, it had one of those infamous Kohler engines and was not that great in the first place.
Not sure of the manufacturer, but the JD filters (and parts in general) aren't cheap. Thanks for the note.
does the power steering and lift actuators share the same oil or are there different pumps and fluid tanks for them?
K71C, the trans seen here, has outputs to the lift cylinders and power steering box. All self-contained system. Output and return are located on the right side of the lower trans.
Great video! I know it’s been a year since you posted this but I am troubleshooting a possible oil leak in my JD345. What would be the best way to go about finding that leak before I invest in changing out the filters and adding new oil?
Do you mean engine oil or transaxle fluid? If you have a kawasaki engine, the valve covers leak engine oil, but it's an easy fix. If its leaking trans fluid, I guess the best thing to do is clean it up good, then drive it a bit and hope the source of the leak becomes obvious.
I’m referring to the transaxle fluid. Thanks for the advice, I’ll clean it up good, drop a little more fluid in there and then drive it around to see where it’s coming from. Thanks for responding so quickly!
@@brentcoates3278 there only three seals
One under the pulley (which usually runs down the transmission) the other two are on each axle. There all the same seal
The hydraulic fluid running down the transmission, is a indicator it's the top seal. Is what I meant.
I watch your video why did you not change the drive belt while you had the fender off just thought i would ask.
Good question. I agree with you that I probably should have done that.....
After changing the transmission fluid & the inline filter in my 345 John Deere garden tractor my deck constantly drifts down when it's up
Did you change the drive belt while you had the fender off? It looks pretty aged.
You make an excellent point. I did not change the belt, but I advised the owner that it might be a good idea to do so in the near future. Thanks for watching and commenting.
Did you prime the lines? I added 4.7 qts to my 325 today. It reads high as the fluid has not circulated to the filters. If I turn the key to start without starting (spark plug removed), will that prime the fluid through the lines?
That will probably work, but I don't know if "priming the lines" is required. I did not do that, as the manual made no mention of that.
Buckwsr it was only high because the pump hadn’t run yet of course which would circulate the hydro fluid to its respective places. All is well! Just wanted to make sure I wasn’t going to destroy the pump or seals by having too much fluid at first. Thanks
Thank you for the video. I am having a problem with the deck on my 325 John Deere L&G mower. The lever that makes the deck rise and lower will not move. Do you have any suggestions as to what the problem is? I guess while I have it apart I will change the fluid.
Can't really help you with that....I know the deck features a hydraulic lift....but I no longer have that tractor on site, so I can't really recall how that was all set-up....I hope you can figure it out!
My reverse on my 345 is going slow ..does this mean I need to change out the hydro oil and filters?
Possibly. But I would start by checking all linkages from the pedal on back. Verify full travel of all components, and keep an eye out for sloppiness or worn out areas.
A good informative video.
If it is leaking Hydraulic fluid will it cause the power steering to be tight hard to turn mower and it also made a noise . . I still haven't got any one to fix the leaking under neath . but I still mowed my back yard last week.and found it hard to turn the power steering was tight. Linda Meyers
Hi Linda. This is not my tractor, and I did this job a few years ago. I really don't think the transaxle fluid and the power steering are connected. Your steering issue would be a separate issue. Sorry I can't be of more help.
Got a question what is the thing called that the filter and the two hydro line go in to I know it come off just mine is broke
I'm not entirely sure what component you're referring to.... Go ahead and look up the service manual which is available online through John Deere....
Bonjour je me fais plaisir en achetant un tracteur tondeuse john deere 355gx diesel d occasion. Mais gros problème moteur et au bout de 20 minutes de tonde, perte de puissance, pourriez vous m aider à résoudre ce problème. cordialement merci
How many quarts did you uses? FYI I think you missed a drain plug or didn't show it. The trans is divided into two internally connected cavities. Rear drain plug (A) will drain differential gear side and front plug (B) will drain hydrostatic side.
Thanks for the note. The online JD service manual speaks of one drain plug (manuals.deere.com/cceomview/OMM143471_E0/Output/OMM143471_E011.html). The stated capacity is 4.7 quarts. I added the full 5 quarts, so I feel confident that we had adequately drained out all of the old fluid.
Yes you are correct. I assumed the gx345 I have and the 345 used the same trans setup. That’s what happens when you assume lol
well, now I will be prepared when it comes time to service a gx345!! Thank you.
Looks like the belt is in bad shape . why not change it while you have it apart ?
Having the fenders and gas tank off isn't going to be much help in swapping that belt. Removing the deck is a better time for that, which you just about need the deck removed to do so anyway.
Much easier to run it with the seat pan off. Then fill as necessary.
The transmission belt looks bad also. I’d change it while you have it apart.
Yes, that would have been a good idea....
Hope u changed that belt lol
Looks like the drive belt needs replacement to
That fluid looks very thin. It reminds me of the CHF 202 that my Volkswagen takes as power steering fluid.
But is your name really John Doe?
Thats basically over priced mineral oil! It feels and smells like it!
Good video, know I know don’t by a John Deere cause they are absolute junk!
A serviceable transmission makes it junk? The 345 is the best belt driven garden tractor ever made.
