Thanks to everyone for the compliments.
Here is a cheesy video if anyone can't sleep
this should do it.

Great video. That's a tough situation you're in, but looks like you have the know-how and ability to fix it. Anymore I've come to the conclusion I needed a spare parts tractor to keep mine going and went that route. Unfortunately it's pretty hard to just get one of these tractors at any time either working or for parts (and cost is obviously an issue). Good luck and keep us informed.

Here are a few pictures of the 4 wheel drive gear
after I turn it 180 degrees. It now will engage.

Amazing the last guy working on it didn't see that when he assembled it. Great job!

Goes to show that a few pics here and there can really help out when putting things back together. I bet whoever did that was questioning which way it should have went at the time. I guess they had a 50/50 chance if they were in a hurry and didn't want to trace out the mechanics behind it.

I was able to remove the transmission from the rear diff housing.
there are a lot of metal chips inside. After looking at the transmission
I believe that one of main ball bearings failed and that whole shaft
flopped around inside of transmission and caused a lot of
problems. That shaft is the one that also has the 4 wheel drive
gear on the end. I think that gear was replaced because the original
one broke into pieces and I think that one of those pieces jammed into
the 4 wheel drive out put gear which then broke the chunk out of
the front gear set cover. I will be taking the transmission completely
apart now to clean it and check for other damage.

Advise to previous owner: "When you hear metal to metal grinding, stop the tractor and have it repaired"

Nice documentation.

The gear that's welded to the shaft in the fourth picture looks odd to me. I've never tore down an Iseki gearbox but I did take apart a Satoh one and none of the gears I can remember were welded to any of their respective shafts. They all had splines and lock rings. I would think welding a gear would cause distortion of the shaft, especially welded in what appears to be a continuous circumferential path like that. It's a nice looking weld so maybe it is factory but I'd feel better knowing it's suppose to be that way moving forward. I don't have my parts list handy so I can't confirm anything at the moment. I'll take a look when I have access to it unless someone else can in the meantime.

 

[TomSeller]

But why just the one gear if the weld were factory? I think your hunch is right, it looks like a repair job.

I was able to polish all of the burrs and smooth out some of the chipped
teeth. here are a few pictures of the gears after polishing.

I turned/machined the O.D. of the clutch shaft where it was badly worn.
I then got a piece of oil lite bronze bushing material and machined a new
pilot bushing to press into crankshaft. here are a few pictures.

I finally had time to clean the inside of transmission case.
It cleaned up nicely. While I was cleaning I decided to check the reverse
gear because if felt to be to loose on its shaft.
Well more bad news, The needle bearing inside of the reverse
gear failed and wiped out the reverse gear shaft.
So far I've had no luck finding a replacement. Another setback.
here are a few pictures of the trans case and reverse gear and shaft.

Just a thought you might have it spray welded and reground,if you can't find one.

I may have to undercut the shaft where its worn to a smaller and concentric
diameter and then have it hard chromed to an oversized diameter and then I'll
have to set it up in a cylindrical grinder and grind the O.D. back to
the correct size.

I had the differential assembly which still had the tires on it
resting on my floor jack and my jack leaks down over time.
So the jack leaked down and the diff rolled forward and
the center assembly turned up side down. No harm
there was no oil in it and nothing hit the floor. When I
lifted the center assembly up right something in the left
wheel jammed in the reduction gears. I rolled it up side down
again several times and finally I heard something drop
inside the case and now the wheel turned free. I though
hmmmm but OK I'll now work on other parts needing
repair. Today it jammed again so I now have to remove
axle assembly and see what's up. Well here are a few
pictures of what was in there

 

[TomSeller]

Well I guess that proves out your earlier thought that a ball bearing cage failed ! You sure do nice work.

How did the transmission oil look when you first got the tractor? Was the level low? Was there a lot of water contamination?

the oil level was not low and the oil did not appear to have any water in it.

Here are a few pictures after I cleaned the differential housing and the axle bearings. Also a few pictures of my train wreck of a garage
and my home made A frame to hoist the engine when I split
the tractor.

I am a 73 year old woman and I need some help. Could you tell me where the alternator is located on the Bolens G154, so I can take it off and get a rebuilt one. If you can help I would be very thankful
