226D Front Drive Always Engaged-pics

Only speculation on my part. If the shift arm will not go in the groove then remove the inside bearing. It should not be that hard to remove. Probably take a rubber mallet and hit on the sliding gear to remove them both. Then put the bearing in the housing, put gear and shift arm in proper places and start sliding the shaft through them. Things should tap in without unusual force until outer snap ring slot is showing enough to install the snap ring.

I can confirm your speculation. A few taps and it started sliding off. Thank you.

Got to the part where I have to hold two steel balls with a spring between them and tap the shaft with my third hand...long day so I gave up until tomorrow. Good news is I cross referenced the shaft seal part number and Napa had it, for about 1/2 what my local Yanmar dealer can have it ordered and shipped in.

Had to heat up the shift arm and bend it out further than I had already in order to get the proper engagement. The detent was tricky but I used some grease to hold the bbs in place while I tapped the shaft end with a rubber mallet. Then tapped it the rest of the way in, put in the snap ring, and persuaded the seal into place. I made sure the shift handle was on the correct way and drove it on the shaft so I could insert the roll pin and call it a night. I will finish the install tomorrow afternoon.

I have to mention that it bent the shift arm and all but wrecked the shift block while it was being forced into front drive that fateful last time when the whole works finally succumbed to the abuse it was being given. But the roll pin adjoining the handle and the shaft, those things must be incredibly effective. The holes through the handle and the shaft were not rounded or disfigured, and the roll pin showed no sign of any trauma.

Thank you for your guidance and encouragement Winston1, very much appreciated. This is one more part restored and on the way to being the true beauty it once was. Amazing to wonder how long it would have continued to serve under the conditions it was in previously. Possibly years before it became unuseable and had to be serviced. It was stored indoors pretty much the entire time since new and that may have been its saving grace but hard to tell.

Here’s a shot from its younger days probably 1985 or 1986. I noticed that is actually the loader that came with it, I do not know the brand of it but along the way someone has fabbed a brace to secure the loader to the back axle which completely blocks the suction filter from being removed and replaced. And of course it is welded to the fel brackets that run perpendicular under the bell housing, which means the entire loader must be removed or at least detached in order to perform maintenance that is otherwise very simple. Ah well, watch for more photos and rambling paragraphs from me on that someday soon.

...and I did the one thing I was absolutely not supposed to do. I took care not to, I thought. I lost a bb. The drive shaft looks like it had somehow come undone in the front and spun freely inside the tube for a bit. It was together and the front drive was working fine when I took it apart. The previous owner had it worked on by a questionable mechanic. Not sure how one would accomplish that unless they were working on it. So who is to say that there were six bbs in one end to begin with.

Here are some pictures, I cannot imagine anything else causing that type of damage in that particular spot. Definitely odd though.
