Now that the weather has started to cool off down here I've started doing things to the BX22 that was left to me by my neighbor that passed away. Some here may remember my "BX22 Left To Me" thread.

So far I've put a new seat on, changed the front end oil over to 80/90 weight grease, tightened the front end castle nut which bad loose and fixed all the oil leaks on the front end.

Today, I changed the HST oil, filter and cleaned the screen. I'm attaching a pic of the screen prior to washing it out so everyone can see and comment.

I've been around this tractor since it was new and have my suspicions that the HST oil has never been changed or the screen washed out. However, with 1600+ hours on the tractor the HST functions just fine.

My next quest is to replace the HST fan since ALL the blades are gone.

If has not been serviced you will want to adjust the valves. It is scheduled at about 1000 hours. The valve cover seals with a big o-ring so you may get by without a new one if the old is not leaking.

My seat is shot. Which did you get and how do you like it.

3v0, after scouring the internet and looking at numerous seats I ordered a new seat from our Kubota dealership here in town. Every aftermarket seat I looked at did not have the correct bolt pattern so I figured why mail order it and go through the headache of sending it back if it doesnt fit. The seat from Kubota was $90 and had the correct bolt pattern. HOwever, the bottom of the seat pan is stamped differently from the original seat and requires two pieces of predrilled and machined metal bar stock ordered though kubota so the seat mount with bolt up flush.

Good for you--getting a very nice SCUT from someone you knew......

Take care of it--change fluids when needed--keep good oil and fuel in it and will last your lifetime with just a little care..:thThumbsU
You lucky dog! Show some pictures of the ride--I love the Orange...

Glenn, friends like Fred are few and far between. Check link below for pics.

3v0, good point on valve adjustment. I'll add that to the list. Are there any 'gotchas' I need to know about. I a sheet with all the information. It states to remove the glow plugs.

Is removing the glow plugs straight forward? From what I've read, they basically just screw out. If that's the case, has anyone had any issues removing them? Are the bad to ring off?

OK--I just went back and read thru the original thread--times like those try a 'good man'--plus the thought of losing your good friend.....

Kudo's to you for handling it correctly....Some would not have done so--

Now let's see some TLC on that bad boy, and then some work that it does...

You opened up a can of worms here-Mr Ehenry.....:fing32:

I've decided the next several jobs I'm going to tackle are HST fan which will include new CV joints and boots on HST shaft and while the shaft is out, a new fan belt. Valve adjustment will probably happen this weekend.

A few more things.

The older BX's like mine suffer from a few design problems.

#1 Air filter mount breaks off.

#2 Power steering lines start to leak.

#3 Power steering cylinder goes bad.

My tractor is suffering from #3. Kubota sells an improved replacement cylinder for around $250. I understand in some cases it is possible to repair the existing cylinder.

About every 100 hours give the hi lo shift linkage under the seat a shot of WD40. Without it shifting gets harder over time until it is impossible.

All my lights stopped working. Replaced the 3 dead switches with marine grade units. May have read about doing that upgrade here.

My next upgrade will be adding shims to raise the hydraulic pressure to the FEL.

3v0, Of the three things you list, the only thing that hasnt been a problem for the steering cylinder and lines. I replaced the air filter brackets last year.

I also plan on shimming the relief valve to bring up the FEL pressure after I get the couplings for my pressure tester.

Mr. ehenry--there is another member on here that has a slightly newer model of the BX, and he has done quite a bit of work/improvements to his over time.
Look up Volfandts threads. Dave is a really nice, quiet guy. Very mechanical type and pretty obcessive about his equipment.
(I like him 'cuz he has some old Wheelhorses also)

Dave and i have corresponded several times over a couple different issues. He's a very knowledgeable and helpful friend but most everyone I've come across on this site it !!

Today, I continued the quest of the refurb....I adjusted the valves. Only three of them needed adjusting. An intake and two exhaust. I also pulled the propeller shaft to replace the HST fan. The only issue I had getting it out was one of the stove head bolts that holds the floor pan down was seized and rounded off the little square hole and I hugged H E double L with it.

Both CV boots and joints need replacing. Got the parts ordered for that. Should be here middle of the week.

Propeller shaft rebuilt and installed with new HST fan, FEL relief valve shimmed with 3 .02 shims. Brought the pressure up from 1750 to a tic over 2000. The lift is great but bucket rollback still seems a little weak.

Got the BT600 backhoe remounted and greased. Found the return line to the tractor has a pretty good leak so I put the pins in the backhoe and disconnected the lines to it until I replace the leaking return line.

While greasing the the FEL I noticed the bottom pivot pins on the FEL bucket are worn pretty good and I cannot get them to take any grease. I am going to replace the grease zerks and see if that will allow them to take grease. If that doesnt work I may try removing one of them and see what is going on with them

All, Just a short update to my project.......I'm not sure if its the age, 16 years old, or my hydraulic pressure gauge is off. But every time I replace a leaking hose I replace both hoses. Then another hose starts leaking. It wont be long until I have replaced every hose on the backhoe. I've also had repack one cylinder. Just yesterday I was doing a little work with the BX and both FEL lift cylinders started leaking. I've checked the pressure again to see if maybe I'd get a different reading but its still just reading a tick over 2000psi. Any of yall have ideas? Is it just the age of hoses and seals and the fact that the tractor sat for almost a year unused?

Did it sit outside for any more of its life than a year, used or otherwise?

Discussion Starter · #17 · Mar 28, 2016

The backhoe attachment did sit out in the elements for a year or more. The tractor and FEL were generally stored under a shed for most of its life.

Not sure if this applies but I bought my bx22 new and almost immediately it started blowing hoses. Whenever one blew I would go to a local place and have them make me a hose. Never had the small hose that was on it so I would go to the next size hose up. After about four or five of them were replaced I called the dealer and started to complain. He brought me a new loaner and took mine back with him. He put a gauge on it and started experimenting around with it. He soon discovered that if you did a certain combination of things like up and tilt at the same time the pressure would spike beyond the hoses rated limit. The dealer said he put a pressure regulator on it. Said it should have had one from the factory but it didn‘t. Often Ed wandered if that was correct but it stopped blowing hoses after that.

I'm still around lurking mainly. I come and glean the knowledge of other members here when I need help.

Thanks for asking about me Newsman !!

Makes me feel missed !
