So, A while back I picked up a Cub 5234D with ~450 hours on it. The seller was one of those guys that wasn't very mechanically knowledgeable, and didn't know the issue/what needed to be fixed. He had the tractor at a dealer after the transmission went BANG and it stopped moving, this is after he had the tractor in for transmission repairs a few months earlier. The dealer told him they'd call him with an estimate. A few months later, they called him and told him if he wants his tractor back, he better come get it, since they are going out of business.

The tractor was partially disassembled by the dealer. The hydro pump/motor and linkage were missing. The driveshaft was bent and snapped one of the u-joint crosses. The rear fenders are pretty banged up, cracked and pieces missing. I got it for what I think is relatively cheap, got the package of loader, 60" mower deck, snowblower, and tractor for about what the loader attachment would cost.

After an eight hour drive each way, I got it home.



First task was to jockey it into an area to remove the loader. I tied pieces of steel angle on the arm cylinders to hold them up, and chained the bucket. I did have the fenders and seat placed on the tractor just so it didn't look like such a pile sitting in the yard.



Next was the adventure of removing the loader without hydraulics. Compounding the aggravation was that the front loader bracket was mounted UPSIDE DOWN, requiring careful jacking and blocking to support the loader as I removed the front loader mount, and the cross bar from the loader frame. After some time, separation was successful.



Getting ready for teardown



Rear hitch removed



ROPS bracket removed



Transmission removed



The frame and transmission are covered in dirt, oil, and diesel fuel. Before any more teardown occurs, things are going to get a thorough cleaning.



Once things were clean enough, I opened up one side of the case for inspection, and started pulling gears and shafts out of the case. The interior of the case is very clean, no filings or debris.



The bearings behind the hydro were very dirty since they were exposed to the elements for who knows how long. I didn't want to chance just cleaning them and hope for the best. I purchased new bearings and installed them.



Since everything looked decent in the main case area, I flipped the transmission over and opened up the 4WD gear area. I had a concern with the front output shaft since it seemed to be very wobbly and the seal was leaking.



4WD shaft removed. I was wondering why it only had a single roller bearing at the front end, and no support at the rear, then I realized the shaft end was broken off. New replacement shaft on the left.



Now here is the doozie: shouldn't the broken off piece of the shaft be inside the 4WD pinion? I guess somebody who had it apart before pulled it out, shrugged and tossed it in the trash without bothering the replace the busted shaft it was part of.



Put everything back together and sealed up the right side of the case.



Installed all the gears and shafts back into the left side of the case. You can still see paint marks from the last guy that had this apart.



Left side all sealed up.



Ready to reinstall in the frame. There is a rag where the 4WD shaft goes, I didn't have the new shaft yet.



New hydrostatic pump mounted. This was another adventure since the two bottom bolt holes were stripped. Holes were repaired with Heli-coils.



Commencing re-entry procedures





Since the rear axle was back in, I took a break from it and tackled the leaking front knuckle. There was water in the bottom of the hub. The knuckle bearing was thrashed.











Back to the rear end again. Hydraulic lines reconnected. I also straightened the frame rail flanges where they were damaged by the flailing driveshaft.



Things were incorrectly installed for the mower deck lift, causing the lift link to rub on the 4WD linkage. Half of the diameter was wore away, so I restored it with some welding/grinding.



There were 2 different styles of couplers on the tractor. I replaced two so they are all the same style. Now that the tractor is running, the remaining old two couplers weep, so they will be getting replaced as well.



Repaired the damaged wiring harness and fuel lines. I also added wiring for tail lights and reverse/work lights. Fuel tank attached. The carnage bent the front seat bracket, so that took monkeying around to straighten and get aligned so the tank and fenders would fit properly.



New driveshaft and fan installed. Before installing the driveshaft, I primed the pumps by using a hand drill and socket.



Foot board back in place.



After some careful measuring, I drilled holes for the tail lights. Didn't want to mess this up after buying new fenders.





After that, I finished installing levers and other trim pieces.





Reinstalled the loader.





I still have a few things to do like change the engine oil/filter, and fix a few small leaks. Working on getting some steel for suitcase weights so I can actually use the loader safely.

Nice job of getting everything right again on that. Great write-up as well.

What about re-installing the ROPS?

Bill,
Really great job!:thThumbsU You now have a machine that should give you years of trouble free service. How long did all of that take? Also do you figure previous owner did all that to it? And what in the heck was he doing to break it so badly? Or was a out of biz dealer to blame for many of the miscues? I'm betting the missing parts are lost somewhere in his former show.
All in all that trip sure was worth it. Thanks for all the pix.:fing32:

PS: Guess I'll have to use the ginormous yellow tractor for this post.:yellow:

About the ROPS, I don't have the bolts yet, but luckily it's just grade 5 hardware. It is a one piece non-folding bar. I don't know if the tractor will fit through the shop door with it on, I'll have to measure. Also would make mowing around trees a hassle.

It probably took around three months to get it going. the biggest waste of time was waiting for parts. An order of parts at the local dealer took 4-5 weeks to arrive.

I think one of the contributing factors was a lack of maintenance, things weren't greased, cleaned, or repaired/replaced as needed. I think the contributing factor of the hydrostatic's demise was incorrect fluid. When I drained the transmission, a thin red/pink fluid came out (TDH or some sort of mix of TDH/ATF/hydraulic fluid??) Who was the responsible party for the fluid is anybodies guess. You would think the previous owner's dealer would have given back ALL the parts, but I only got some of what was removed.

That 16 hour trip was only the warm up moment
compared to the rest of quality time you've spent with the new baby.

Your eye for the details and skills really paid off getting it all together the way it should be.

Money spent on the detail parts that could have worked made a huge quality factor gain , good for you. :fing32:


Great job Bill ! :fing32:

Yet another to be proud of.

Very cool! Good job on the rebuild!
Thanks :fing32:
Glad to see all you did to it in one spot Bill! Excellent job and can't wait to see what is in store for it :)
Thanks :fing32:
WOW.. You definitely earned that one!! Great write up and pic documenting. Enjoy the loader, now get to work so we can see what it can do ;)
Thanks :fing32: Got to get the 3pt and counter weights set up before I attack anything serious with this machine. I can't believe that the previous owner didn't have rear weight for the loader, the handling is downright scary when you lift anything.

Thanks Don. :fing32:
You know how it is, if you're into something this deep, there is no point to half-fast it in an effort to save a couple dollars when it will cost more time and money to do it over in the future.


I did a few more things to the machine.

Replaced the last 2 couplers, no more hydraulic leaks



Fabricated and installed grab hooks for the bucket







I acquired some metal rounds ~100 lbs each to make some suitcase weights

Im just seeing this, cool! It must be a SCUT, right? Im trying to decide what the green and yellow equivalent is? 2305?

They consider it a SCUT, personally I think it is more in the league of an X7-- series. Also from what I see, the Deere is a much stouter built machine.
Great job bringing this one back from the near dead. Nice pictures of the process too!

Thanks. :fing32:

Bit of an update.

I was getting a thump now and then that felt like a gear jumping teeth climbing hills, so I pulled the hydro and added more shims to the drive pinion.



Found the 3 point arms for sale on ebay. Ordered them and installed.



When I purchased the tractor, the hood side covers were missing. Ordered a set through the dealer.



Next will be to buy a quick hitch and fabricate a weight rack. I also bought the cruise control kit which I still need to install. Cruise is useless this time of year but will be handy come mowing season.

I hope you made the dif healthy .
boy what a thing to have happen with all the work you did to it.
Jumping anything having to do with gears has to be unhealthy.

All purdeed up now to !

The three point is a real nice addition. :fing32:

Very cool! I like the front tires you put on it. I would also like to see V61's up there

I hope the shims helped. Disconcerting when you hear clunking noises from something you just assembled. I haven't had a chance to test if the issue is solved yet.

The 3 point will be great for a weight rack. I don't have any implements yet.

I matched the one tire that was already replaced on the front. I'm still debating final tire choices since it is 4WD

Got the cruise kit installed. Basically it's a switch, an electromagnet, and a bracket. All the wiring is there, just plug the parts in and mount the bracket into existing holes.



Made some brackets for the rear lights. I didn't want to mess with the integrity of the ROPS, so these brackets mount with the same bolts that hold the ROPS.





Did some work around the shop with the tractor. Relocated a Deere carcass and got some engines out of the shop and into storage.
