My Yanmar 220D

[globalenigma]

I recently bought a used Yanmar 220D. I believed that I had a good deal, but upon arriving at home and using the tractor more issues have arisen. Some of the issues are as follows:
1. the hour meter does not work. stuck at 416.3
2. 4wd does not engage, easily move shifter forward and backwards (will try the wheel test tomorrow that I read on forum)
3. 3pt does not lift as high as I would like
4. whining noise when in higher gears (possibly ring and pinion gears)

Other than that I am very happy with the tractor. So far I have shredded the yard, dug two 5x5x3 ft holes to push burned debris in, and used blade to push debris on fire. Tractor has operated smoothly so far. I am just worried about the 4x4 issue. Would really like to have this working.

:welcome: to TBN! Looks like you got a sweet tractor. As far as the whining noise, the tranny in my 169D makes a whine too, but after inspection of the transmission it is normal. I'm not saying the noise you are experiencing is normal, but it is a possibility. The hour meter problem is very simple, the cable has a break in it. Hoyetractor.com sells new cables which can be installed in about 20 minutes with little experience. The 4wd issue I have read about but don't remember the diagnostics on how to fix it. There is a thread regarding the restoration of a 336D that may be of assistance. The 3 point lift height can be changed by removing the bolt or pin that connects the lift arms to the lower arms and moving it one hole up. If it is already in the top hole i would look into either longer lower arms or a quick hitch system. Be aware that if you get arms that are too long you risk damaging the seal in the lift cylinder that lifts the 3 point up and down.

Welcome to the forum, and congratulations on your purchase! I don't know how the YM220D is laid out, but I had problems with my YM186D's 4 wheel drive engagement. You can read about it here if you scroll down through a bunch of my review of a new-to-me tractor. Here is a picture of the bent and twisted shifter finger:

Basically, on that machine, the 4 wheel drive is engaged by sliding a 3-toothed coupling along a splined shaft. Moving the lever forward moves the coupler away from engaging the driveshaft, while moving it to the rear moves it toward engaging the driveshaft. Apparently there are two common failure modes: One is simply the breaking of a roll pin that retains the shifter lever to the rotating component. The other (and what I suffered) was/is the bending (for me) of the finger that interfaces with the shifter fork for the 4wd coupler.

My tractor had been bought new by the guy we bought it from, who used it to cultivate strawberries and other crops exclusively in 2wd. After something like 25 or 30 years of staying in 2 wheel drive, an overzealous new owner's zeal pushed too hard ( a boot may have been involved in a kicking fashion, come to think of it) and simply twisted and bent the L-shaped finger (it's only about 3/8" metal rod) so it wouldn't engage at all. I repaired the finger, and have kind of managed to get the shifter operating properly, but I have come to just leave it in 4wd permanently, since about all I use it for is pulling an absurdly overballasted little 4' disk to tend my orchard, so I need all the traction I can get. The shifter is still a little sticky sometimes, but I can shift it if I need to.

If your 220 is more like my YM240D, I've also had that shift lever break, too. :laughing: (Technically it was the high/low shift fork, but they're the same thing for high/low or 4wd/2wd) You can read my explanation of that fix here. You can also see the high/low shifter finger (the 4wd is similar but on the opposite side) circled in red in this picture:

The good news, I think, is that (if I recall correctly) there is more room on the left side housing (where the YM240D 4wd selector is) than there is for the high/low shifter. That means you should be able to easily pop the assembly out and fix or replace it without doing some "make it work" engineering (and possibly ending up in a "There, I fixed it" chain email...).

For what it's worth, and as a word of encouragement, I think I've had more things break because of my tendency to buy basket case compact Japanese tractors much more than any real design flaws or shortcomings in quality. The real lesson is don't let people use their feet to push on shift levers: That's what bent or broke both of mine.

This is the drop box on a YM2002d. I believe identical to the YM220D.

I want to thank both of you; Johndeere3720 and 284 International for not telling me just to search the forums. I did not mention in my post that before posting I did a ton of searching on the forums. I have over 60 tabs open in firefox. I have read your one post on fixing the 4wd 284 International. I was hoping my would be easy to fix but with all that you have written here it has made it make even more sense. I am glad I posted this and that you explained what to do and make it more clear.

Johndeere3720, I read on the forums about the hour meter but none were as clearly stated as yours. Thank you, I will go see if I can trace the wire out and see if I can find where it is messed up or exposed. Thank you for the advice on the 3pt that was greatly appreciated. Also as far as the whining you did make me feel better. I do believe it is normal. My family owns a farm and we have a few tractors up there. One of them is a MF65 and when it is in high gears it also whines. I now feel better that this is halfway normal. It may be some worn gears or it may not. I do not believe it is worth tearing it apart to find out.

winston1, thank you for the exploded diagram I believe it helps.

I hope what has been suggested helps you. You may be lucky and it's just a roll pin, but I don't think it's the end of the world one way or the other. Even in the worst case scenario, you can manually place the machine in 4wd and just leave it if you're not going to be on pavement.

Also, you ought to consider swapping the front tires on your tractor from one side to the other. The rims are on "inside out," presumably to give better stability. All of the Yanmar manuals and suggestions I've read online suggest that having the rims running wide like that can cause damage to front axle components. It will also probably steer easier. It will track better in 4wd, for sure.

284 International, I just switched the tires on the tractor. Thank you for pointing that out. I would have not noticed that for a long time; if ever. I also did the test on the tires while I had the front end jacked up. When I spin one tire the other rotates the opposite direction. To me that is a little relief.

Also I climbed up under the tractor and looked at the 4wd engagement lever. I saw what appeared to be a pin and drove a small nail through the hole. Nothing came out and my nail was all the way through. I was excited at first because I thought that now I could engage my 4x4 because it was missing the pin. Got out from under that tractor in a hurry to test. No dice! It was still just as easy to move. I crawled back under the tractor and got some better lighting and it appears that there is a "roll pin" in there. So I guess I will have to pull off the shifter and see if I can see the 4wd engagement from there.

If you have any other suggestions please let me know.

I believe to make any internal repairs you will have to drain the transmission. Then remove front drive shaft. Then remove six capscrews and then the drop box.

 

[284 International]

Is your 220D the same as in Winston's diagram? Is the linkage the same? It would be nice if there was just a missing pin or something. Otherwise, I think it may be as Winston said, and you'll have to remove the drop box to see what's inside.

Rotating the wheels and confirming the other side spins in the opposite direction verifies that the axle shafts and hub assemblies are intact and connected through the differential. You can test the driveshaft and ring and pinion by spinning both tires in the same direction. You should be able to see the driveshaft spin.

If you do have to tear into it, make sure to take some photographs and post them up here as you go. Good luck!

My 220D is a lot like the 336 in my opinion. I believe I also have to drain the Transmission Fluid and drop the dropbox. I only have the lever, a bolt, and this spacer on the outside. So I am sure I will have to get inside to fix it. Right now that is not on the top of my list.

I am adding a guest room in the garage, and building shelves in there to get more organized. Also just dug some holes in the back of the property to bury some old stuff that never burned in the burn pile. I have finished the hole and pushed the stuff in, now it just needs to be leveled.

One last thing on the list is to finish the driveway and shred the property for the winter.

Thanks for the help so far, I will really get back into this later in the winter and promise to post pics of what I find.

While browsing around I found an image that I think best represents what I see when looking at the tractor.
