Removing BH92 Backhoe

[NordTrac]

Tried to remove the backhoe for the first time today following OM's instructions. There was no position/geometry that would loosen the 2 large pins enough to pull them out.

On some YT videos, they make it look so easy, just pulling the pins with their fingers.

Am I missing a trick?

Make sure you’re on a completely flat surface and use the backhoe, pushing down on the ground and your outriggers, need to play with it to find out what takes the tension off of the pins. I always use a 3 pound sledge to assist me in hitting them, but it’s obvious when they’re looser or tighter

Yes ! Very small, gentle movements to find the exact point where the tension is released. Always did this at idle rpm.

+1 on the outriggers.

If it's anything like my 77, you can visibly "see" the pins relax when you hit that "sweet spot".

Then you can push them out with 1 finger.

I have never needed any sort of hammer or anything.

I would agree that being on level ground will help and being at idle will help too, however, I had one of pins "fall out" (get knocked out by a stick?) when I was using it one time.

Thats how loose they get when they are in the right position.

Agree with the above. No sledge should be needed. the pins on my BH92 slide out by hand.

I have the same problem with my BH77. And have since I’ve had it One pin slides in very easy. But the other I have to use a rubber mallet to put it in and a screwdriver to remove it No adjustment with the stabilizer helps

Like other have said, you have to make really slow movements to get the pins out. I stand to the side of the backhoe and pull on one of the pins while moving the controls till the pin moves. Once you get the hang of it, it is a lot easier.

Thank you all!

Can't try it right now. It's snowing pretty hard here. It'll probably be next weekend before I report back.

I agree with the others. I struggled quite a bit a number of times. One of those things you get a feel for by doing.

I can relate to hitting the "sweet spot" with one finger but that's not for me to say...

You have a larger BH than the 65 on my B2620, but I'd recommend a dolly for the BH if you are taking it off on a hard surface. I DIY'd one based on some forum and Google searches. It allows you to move the BH to optimize connection rather than moving the tractor. Subtle shifts of the dolly can really ease pin alignment for insertion along with moving the arm/bucket against the ground (or dolly) rather than using the stabilizers.

Here is what I came up with.

With the boom pointing straight back, dipper and bucket curled, lower the boom until the bucket contacts the ground/floor. Lower both stabilizers until they're about 8" from the floor.
Now gently press the boom control lever forward to further press the boom down until you see the backhoe frame pins loosen, as the boom action will push the backhoe frame top towards the tractor, pivoting on the lower pins where the BH weight is set. Pull the pins.
Now lower the stabilizers to just lift the BH weight off the lower pins.
Then pull back gently on the boom control lever which should rotate the top link pin bosses back an inch or so from the tractor subframe.
Now lower the stabilizers further until the lower BH pins each just clear the frame pocket.
Now ease the tractor forward about a foot, then slowly and evenly raise the stabilizers to lower the backhoe belly to the floor. I keep my BH77 stabs just braced to the ground to prevent any backhoe tippy motion while off tractor.
Shut off the tractor and operate the backhoe hydraulics control levers through all positions to relieve any cylinder pressure. Disconnect the BH hydraulic line and reconnect feed back to the tractor.
Done.

Use Corrosion X on those large pins and PTO splines for easy R&R. Fingers always to remove sometimes a gentle tap to install. Have improved with practice.

I don't have a hard level surface yet. I missed the window to get a 40' HC container in before it started to taw. I'll have to wait probably until mid-May before I can make that move.

The dolly is definitely on the to do list.

I wanted to remove the BH for 2 reasons:
1- for fun
2- to get the 3PH geometry measured in order to build a DIY ballast (I can't seem to find the info for the MX5200 with R4s).

Thanks for the step-by-step procedure. Pretty close to what I tried. Need to spend more time on it this weekend.

You are on track... spending more time with the on/off procedures for your BH breeds competence and confidence. I have done it so many times now that it is smooth and quick.

Nothing wrong with a ballast box. Built one 45 years ago for 2wd tractors to pull logs out better and old trip bucket loader. Sat unused for decades after 4wd tractors and better, heavy 3pt attachments. Mowers from finish to tree cutter have plenty of weight. Land plane also heavy. Tis the season for tiller. Hillside farm so all the tractors have rear wheel ballast. One has wheel extensions. Operate 85% in 3pt mode. When backhoe is attached always having to swing up hill for balance and dance the outriggers.
