I have the MX5800 with the BH92 backhoe. I really love this thing but wish I had a ripper tooth for it. Some of those stumps take a lot of work with the 24" bucket.

My problem is in removing and installing the backhoe. Everything works as advertised until I attempt to remove the left side pin. It was really difficult to get out when I first go it, so it went back to the dealership to clean out/ align the holes. That made it "better." Still, when it is time to remove or install it again, that same pin can be a real pain.

Is there a secret to this? Am I supposed to have to pry in out or tap it in?

I'm all ears (eyes).

Have the same problem with mine, except the right side is tight. I notice on a hot day it is more difficult than in the cooler weather. It should wear in over time. What I ended up doing was grinding more of a taper on the pin. Not past where it seats mind you, that would make thing sloppy. I also took a die grinder and flapper wheel and removed the paint in the hole. You have to be careful because is you go too far you just made a sloppy hole. Mine is still tight enough that I can just barely turn the pin to work it in and out. I my work on it a little more sometime but tighter is better than looser.

I don't have the same tractor or backhoe but my top pins are really easy to remove. I just pull them out or reinsert them with my hands, no force necessary. If only one side is difficult it would lead me to believe something is tweeked, either on the subframe or backhoe. Wonder if it would line up if you had the backhoe in place and loosened the bolts on the subframe a little then retighten. Ormaybe if you knew which way it needs to move, loosen the subframe bolts slightly and us a hydraulic jack to move the subframe slightly.

I have a L3560 HSTC with a BH-92 that I bought this spring. The dealer didn't put a long enough hose on the tractor to the backhoe so that I could pull away a little and remove the hoses. I was taught to use the bucket down pressure to relieve pressure on the pins, I stand and work the joy stick until the pins are free. Then the stabilizer arms to lift the lower pins off the sub-frame. That is another dealer problem, the right side sub-frame had two loose bolts that were never tightened. The good thing is the nuts didn't fall off and I was able to tighten everything up. You have to check on everything the dealer does otherwise if something happens, they will say well, you didn't do your routine checks before operation, and only you will be responsible for any damage or accidents, not the dealer.

My bx bh does not disconnect/reconnect that easy either.

I have to find the sweet spot with bucket pressure and maneuver the stabilizer arm on that side.

Are you on level ground?

Is the tire pressure the same on both sides, if not the back will tilt and this may lock the pins.

Do the pins move free in the hole with the bh off?
If so you may not want to grind them.

I found that a dolly makes a big difference, have the BXpanded dolly and on mostly level ground it is very easy. That and a little grease on the pin too!

I've thought about putting more of a taper on the pins, but I wanted to see if anyone had a problem after doing something like that. Thanks.

That sounds like a good idea. I'd guess with my calibrated finger tips that my misalignment is in the neighborhood of .001". It is just irritating enough that I hate the YouTube videos claiming that they simply slide in and out!

Good thing to check. When I use the previous suggestion of loosening and then tightening the assembly bolts, I should find out if there are any loose ones already. Thank you.

Interestingly, I just checked my tires yesterday, and I was surprised when I used the Helen Keller method of removing the valve cap just to find that the sealed plug came out instead. I had the valves at 12 o'clock and got a serious bath with water. There appeared to be more water in the left than in the right, but because of that, I didn't get to compare air pressures.
I equalized the water levels and then serviced both sides. I should check and see if there is a difference in the ease of the job now.

Good idea.....

Yep, I keep grease around for any slip-fit pins that I removed and install. I have considered a dolly but have yet to get around to making one.

Thanks

I had the same problem one time and, since yours is relatively new it's not as likely, but I had some material build up in the bottom 'hook' on the subframe. This is where the lower pins on the backhoe set into the subframe. There was enough material down there (from brush hogging) that it was causing enough misalignment to really give me fits. Once I cleared that up, I'm back to 'tool free' mount and dismount. As noted, level ground is a must as well.

Good luck...I know how infuriating things like this can be!

Mine is the same way. When I first got it the mechanic had to come out to remove the backhoe. When I went to put it back on it appeared that the bracket on the backhoe is not welded on quite straight. I was able to get the pin in and back out but with way too much effort. Since I won't be needing the tractor now until I start my planned backhoe work this winter it will be going back to the dealer soon.

Also, my boom lock won't go into place.

The thing that gets me is my dealer used to be great. Always right there with an answer to fix my problem, right on top of things when I needed them and the quality of workmanship was great. Now I question if I can trust them any more. As I said earlier, loose bolts, I greased the BH yesterday and one of the grease fittings came off stuck in the grease gun hose. Turns out two others were not tightened into place, I thought I stripped the thread, but they were just loose. Also after I purchased the BH, they installed it and when they changed the too short hose, I got it back and the HYD. fluid was down 2 QUARTS! They never checked or filled the fluid. Good thing I check things.

Ya know, I didn't really look at that. I guess I need to spend an extra moment preparing for installation. Thanks.

They get kids in that really have no clue or havent been trained to do the job, or just plain dont care just as long as they get it done and they can go goof off some place. I see that time and time again

On my BX25 my right side pin gave me some problems. I align the left side and the pin slips right in, but the right only goes in 3/4 of the way. I then put down the outrigger leg, and lift the BH ever so slightly and the pin goes right in. I think I could benefit from a bit of a buildup on the subframe on the right side as well.

Got the tractor back from the dealer last Thursday. Boom lock works now and a quick test showed that both pins will come out easily. I don't know what they did but at least it works now.
