Backhoe Removing a BH90 backhoe

[BarKay]

After digging out about 50 stumps I decided it was time to remove the backhoe and hook up the brush hog. The instructions look easy enough but when it says "raise the rear wheels slightly with the boom and remove the mounting pins" does this mean just take some weight off the wheels, or lift the tires off the ground?
And the big question is--how do you remove the pins? Looks to me like they're stuck pretty tight. And I assume that lowering the boom should remove tension on the pins but I don't get it.
Can someone help me out here?
Many thanks

Push into the ground with the bucket untill you begin to take weight off of the rear tires. This will release tension on the pins. You will know when you have it as you will be able to jiggle them around. Remove the pins, make sure you have the stabilizers down..... lower the backhoe with the stabilizers, then pull forward a few inches. Shut down the tractor, disconnect the hydraulic lines, then couple the ends together (backhoe to backhoe, tractor to tractor), then you can restart the tractor. It takes a little practice, but you will be doing it in a couple minutes with some practice.

Thanks Ductape,

I tried it pretty much that way but the pins never seemed loose. But now that I know I'm on the right track, I'll try it again in the morning. Thanks again, and thanks to everyone for all the tips--this forum has been real helpful to a first-time tractor owner.

Assuming it is similar to my BH80X, loosen and remove the nuts first. Then as you start to take weight off of the rear tires with the hoe, you will feel the pins are completely loose and almost fall out by blowing on them. OK, i'm exaggerating a little bit....... but it will take nearly no effort to push then out. As you start to raise the hoe and put weight back nto the rear tires, you'll want your stabilizers about touching the ground. If not, the whole hoe will fall to the ground once the tension is off of it. Hard to explain in a few sentences, but its easy to get the hang of once you've done it a couple times.

Back on 5-16-2004 "TXDON" posted an excellent message on the removal of a BH90. You can find it on page 20, message # 4911.

I have an L3830 with a BH90, and it gets easier every time you remove and reinstall the backhoe. I think the manual says to remove with the bucket curled, but my best results are always with the back of the bucket flat on my shop floor. Probably the most important thing you can do is find the levelest spot available -- a concrete floor works great.

It's actually a very easy procedure.

A friend and I wrestled with the pins for a while but we got them out. For the first few months I owned the tractor it was stored outside, which may have been part of the problem. The pins had a fair amount of corrosion on them, which we took off with #400 emery cloth. Now I've built a garage for it so it should be OK. And I wiped the pins with a little grease even though I don't usually do that for non-moving parts.

Thanks for the help.

I have always used the stabilizers to raise the rear wheels rather then the bucket arm. This is after the bucket is already on the ground. Once the pins are out I lower the stabilizers just enough to pull the tractor forward, shut it down, disconnect the hydraulics and finish the process.
Be careful how low you go with the backhoe when removing it. I cut the hydraulic line on the pto shield one time by lowering the backhoe too far . Just go low enough to clear the sub frame when you pull forward.

I figure the BH90 should be very simular to my BH75. I use the stabalizers just to get the height and then use the bucket to curl it out of the mount.

I also clean and re-grease the pins/holes everytime I pull the hoe off to keep corrosion at bay.

Great idea! I'll have to try this method

Hi Wushaw,
Haven't removed my BH90 yet, but probably will give it a go this coming weekend. Your method sounds like a good alternative.

Can you just explain a couple points?

I'm sure once I give it a try I'll figure it out, but right now I'm trying to visualize

The link posted above covers things nicely. You may find that raising the rear tires a little USING THE HOE is essential. I'm not sure that using the stabilizers will release the pins completely. If you only use the stabilizers with the backhoe bucket raised, there's still all that weight trying to pull rearward on the attachment pins.

When I picked up my L39, we wasted about two hours trying to get the backhoe back on it. Later, after I had read the instructions, I could do the same task in just a few minutes. The secret was to extend the hoe out a bit and use it to lift the rear wheels. Once I did that, the pins would slip in/out with the pressure of one hand.

No you don't raise the wheels, ya just take the weight of the hoe off the pins, one hand on pin and the other on the controls which would be the dipper ( I belive ) and just push the bucket into the ground ( the back side of bucket) till ya can wiggle the pin and after ya pull both pins pull back on the dipper handle and she will roll out of the cradle.

After ya do it a few times it gets real easy.

Dons explination is a real good one.

Took my BH90 off the tractor for the 1st time today, took about 30 minutes.
Not using the stabilizers, just the boom. Right pin came out 1st with some resistance, then I couldn't get the left pin to budge. Playing with the boom downward pressure very slowly up & down fine adjustments I finally found the sweet spot and the Left pin came out easily. I probably won't be putting the BH back on for a couple months, but hopefully I get the knack of this
eventually

When you buy your new one, make sure the dealer tech pulls the pins and dismounts the back hoe, before delivery.

In my case, one pin was jammed. An hour on site trying to get it out. We discovered orange Kubota paint in the pin's sleeve. Dremel w/wire brush and lots of solvent to clean it all up. If they're right, when tension relieved they should slide in and out easily.

 

[botayota]

My dealer showed me at his shop, and removed and installed the BH90 there, but there's nothing like doing this yourself at home without the dealer present who could probably remove the BH in his sleep since he's done it so many times.
Yes there was some crap & paint in the pin sleeves, so I cleaned and sprayed the pins & the sleeves down with Fluid film, should help the next time I install the BH.

Try this link for a video on removing/reinstalling a hoe on a BX24 -- very similar to the procedure on the bigger tractors.

Drat! I hate it when I forget to post the URL. Here you go.

I had a BH90 w/a L3830 and can attest to the challenges of mounting/dismounting the BH. (It is an EXCELLENT BH by the way...smooth, precise, easy to control.) Several previous posts are right on...namely keep BH on level surface and download TXDON's post...it helps when you aren't doing it everyday. (You don't lift the tires off the ground because that will not releive the pressure/tension on the pins.) I once dismounted mine in an out of the way area on the ground and the following day tried to remount it, but it settled unlevel. It took about 90 minutes to get the holes lined up perfectly to place the pins back in...the tolerance is zero, so perfect alignment is crucial. I did everything possible...using the bucket, dipperstick, stabilizers, etc. to get the darn thing lined up. Anyway, dismount on a slab if possible or use 2xs to keep it level so you can remount without hassle.

I now own a JD 448 BH and rally like the way it mounts as it is lifted into place and the pins are slid in from the seat without a fuss...level ground or not...no matter. On the flip side, the 448 is FAST and takes a while to get used to it. It also has a little more slop in the side-to-side play, so working in tight spots near the house requires extra care. I'm not sure if the extra speed of the 448 is worth it.

Anyway, with time and practice you will find it gets easier. ENJOY!
