4690 BH Install/Remove

[ronjhall]

My new 4690 backhoe was delivered last week. /w3tcompact/icons/grin.gif Dealer had it installed on a 2710. Removed it from the 2710 inside of my barn. When I tried to install it on my 2910 the first time I spent over 2 hours and never did get it installed using the instruction that <font color=orange>Kubota</font color=orange> includes with their manual. /w3tcompact/icons/frown.gif See attached file.

Mechanic from dealer came out yesterday and installed it on my 2910. /w3tcompact/icons/smile.gif He sure made it look easy after I had spent all the time Saturday and did not get it installed. /w3tcompact/icons/blush.gif
He made some suggestion that may make it easier to install backhoe in the future.

1. With backhoe pump attached and running use stabilizer arms and boom to raise backhoe high enough to remove 2 5/8 bolts that hold 3PH limiter bar in up position. This allows bar to drop down out of the way of lower 3PH arms.
2. Lower 3PH all the way down.
3. Use stabilizer arms and boom to raise mast bar high enough to set on top link lower pin.
4. Roll tractor back to align mast bar with lower pin.
5. Lower stabilizer arms to set mast on lower top link pin.
6. Insert upper top link pin. Install both linch pins in top link pins.
7. Raise lower 3PH arms and insert handle pins and spacers into the proper holes. May have to move backhoe around a little to align holes.
8. Install locking rings.
9. Raise 3PH limiter bar up to lower 3PH arms and reinstall the two 5/8” bolts.
10. Install the sway pins in lower arms to limit side movement.
Backhoe is now installed on Tractor.

I installed backhoe on my tractor today in about 30 minutes. I should be able to do it faster with some practice. /w3tcompact/icons/eyes.gif
Removal requires a lot less time. But I’m still slow at that until I get more familiar with it.

Mechanic suggested that the chain for holding the top link pins be thrown away. If the pins with chain ever dropped down and got caught on the turning PTO shaft, it may cause an injury.

Does anyone have some other hints on how to install the 4690 backhoe on a tractor with less effort?

I used it on a small project yesterday. What a great tool. /w3tcompact/icons/grin.gif

Ron,

If you've got a drill that works, stick with it. I've found my dolly makes installation (and storage) much easier and I highlly recommend building one if you have a good floor surface to roll around on.

With the BH on the dolly, I roll the BH up to the rear of the tractor adn attach the pump so the BH is powered. I then position the BH and attach the lower 3PH draw bars. The dolly makes this part real easy. I also leave the sway pins out of the draw bar stabilizers so they can swing freely from side to side.

Once the draw bars are on, I move to the top link, First I put the lower pin through and snap-clip it in place. Now using the hydraulics on the BH I position the BH to raise the mast up and drop the hook part down on the lower pin. It then only takes some minor nudging to get the top pin installed and snap-clipped in. The last step is to pit the sway lock pins back in place and it's off to the races. The process takes between 5 and 10 minutes.

I can think of two things you might want to look at. The 3PH limit bar (the round bar than's below the draw bars on the BH) may need to be adjusted. I have mine set so it's in the lowest possible position to minimize interference when installing/removing.

Second, I found the rigging in the manual to be incorrect for the B2910. The rigging I ended up with can be seen in the attached photo. I can't remember hwo I originally rigged it and what the problem was, but the photo shows what I've been successfully using. I seem to recall someone else posted a photo with their rigging and I think that's where I got it from.

Thanks for the information and picture. I plan on making a dolly. Your picture will give me a head start on how to make it. /w3tcompact/icons/smile.gif

Ron,

Your post takes me back to intalling my 600BH on the L185DT - 20 minutes if all went well, thats why I got the B21 instead of the 3010 with 4690.. mince takes 5-10 min tops to install, and 3-4 min toi remove. We have yet to hear from Boondox on the R&R on his 3010/7500 combo.

Also, Hayden - a nice rig you have to move around the BH, makes for storage and moving around easy. I just drop mine in the corner and block up the base for easier install.

I was looking at the picture of your Backhoe Dolly. Noticed that my Backhoe is assembled different than yours. I scanned the pages from my manual. It was revised last year in October. I don’t know why the difference. But thought you might want to know. Drawing on right is the 2910 setup.

 

[hayden]

Yes, that's the same as my manual shows. I wish I remembered better how mine was originally rigged but I ended up with it the way you see it in my pictures because it didn't fit right the other way. I just don't know if the "other way" was like in the manual or something else.

Are you finding your's easier to get on and off, and is it rigged like the manual says?

Peter

Mine is rigged like the manual for the 2910. I’ve tried it one time since mechanic came by. It wasn’t too bad. /w3tcompact/icons/smile.gif Will get a lot better when I get a dolly built. /w3tcompact/icons/grin.gif
