YM2210D Floppy 4wd shift (part 2)

Postby MRMNTS » Fri Apr 27, 2018 5:46 pm

Hi All,
There is a preceding post where I talk about my 4wd shift lever not doing anything (floppy).
I am starting to remove the 4wd shaft so I can remove the drop box. So far, so good. I'd upload more pictures, but 2 seems to be the limit.
In the first picture, I have removed the screw clamps from the rubber boot and slid the boot forward (A). It also shows where I have removed a bolt tying the shaft to the frame (B). The bolt on the other side would turn but would not unscrew. I cut it off. Ultimately, I believe I need to remove C if I want to get into the "dropbox", to repair the 4wd disconnect. My hope is that when I disconnect the forward end of this shaft, the rear end will just slide out (yeah right).

My next and final picture (2 out of 7), shows where I wriggled the front cover of the 4wd back (A). Tomorrow I will compress that spring (B), remove the pin, and try to catch all the ball bearings that are expected to fall out.

From a fellow 2210d owner:

*It looks like you are running automotive tires and rims? What tires/rims are you using?

*I had to replace my driveshaft. Once the bolts are removed from the rear shaft cover and the rubber cover is loosened, the rear shaft cover will slide forward to expose the rubber bootie with bearings inside.

*Next, you can remove the pin holding the spring assy. in front and release the spring tension. I would place a large tray/tub underneath when pulling the shaft, as the bb's may get lost.

*Now, you have access to the drop box.

*Clean your driveshaft (female) splines and look for damage. Hoye has the shaft for 199.00. If you do replace the shaft, be aware that you may need to grind down the outer diameter of the new shaft to properly fit inside the rear cover (as I had to).

Actually the tires are from the turf kit I got from Hoye. I don't have access to a loading dock so I had the tires and the rims shipped separately via UPS. That worked fine.

I was able to remove the drop box. Getting the shaft out was tricky because of the front loader armature. It took some wiggling but it came out.
Looks like at some point in the past some welding was done to repair this. The shaft holding the main gear was welded into place. I had to break the weld in order to get the main gear out and reach the newly broken piece.

As Aaron had predicted in my initial post, part # 31 was broken. At first I tried to get it out without touching the weld. Not possible.

With the big gear and part #31 out of the way, I see another gear on a longer shaft (I'll add a picture in a later post). This is what part #31 pulls back to engage the big gear to enable 4wd. Shouldn't I be able to slide it back with my fingers? I can't budge it. Perhaps that is why #31 broke in the first place.
Is it worth trying to repair this drop box?
Is it OK to run the tractor in 2wd using my current drop box to plug the hole?
Maybe commission a flat plate to cover the hole while I seek a repair/replacement?

Shouldn't the smooth slotted thing behind the gear move smoothly back and forth?

Yes, the smooth slotted thing is attached to the gear and they slide together on the spline to engage or disengage the 4 wheel drive. I expect you are right and this is what broke #31.

If you cover up the opening it is not going to hurt you to run in 2 wheel drive.

Thanks Winston!
I have a contact that may be able to repair the previous weld. I need to figure out if I can fix the parts inside so that the smaller gear slides back and forth again

Have you contacted the parts department here possibly having a used drop box?

Thanks Winston,
I did and they did. I have ordered a complete used drop box. With that in place, I won't mind tearing into the old one to see why it failed.

Excellent, glad Hoye had the box!

I got the part from Hoye. A little rusty, but intact. It has one of the guide pins, but in a different position. If you look at the picture, the part that I removed from my tractor had the guide pin in position A (you can see it there). The one that came from Hoye had it in position B. Can anybody suggest a good way to remove these pins without damaging them?
Thanks in advance

What difference does it make? Isn't there a pin hole in either side of the case?

I guess there is no difference.

I felt very foolish when I read the last two posts. Dang it, I should have looked. After thinking about it all day at work, I got home and did. There was already a pin in that hole! If I did not remove one of the pins, the new part would not have fit.

To answer my own question, I was able to wrap a rag around the pin in the new part, and wriggle it out with a pair of pliers. I will put it in the other hole.
There was some gunk inside the replacement part, so I'm soaking it in diesel to clean it out.
So far, so good.
