Backhoe BX22 backhoe hookup problems

[bandit67]

I've noticed that my neighbor's BX22 backhoe doesn't seem to want to attach to the subframe very easily at the upper links. It seems that we silicone or teflon spray the upper links every time we hook it up, but the links still don't seem to want to move on their own. We always end up tapping the spring loaded pin in with a hammer to force it between the 2 clamp pieces. After we had the backhoe off the machine again this weekend, we tried moving the clamp linkages by hand, but no luck. I know the little spring isn't strong enough to hold the clamps from moving. One of the clamps usually takes less effort to hook up than the other, but they both seem to be way too difficult to engage.

I'm wondering if maybe the previous owner socked down the bolts at the clamp pivots too hard, thus holding the pivot clamps too tight, and that's why they don't move easily. I'm thinking about loosening the bolts and re-tightening them with my torque wrench, per whatever torque setting is hopefully listed in the owner's manual.

Has anyone else had this problem, or have any suggestions? We both hate having to attach the backhoe, as it becomes such an ordeal. I just don't think it should be this much trouble, or I'd have seen more posts complaining about it.

I've had my backhoe off about 4 times and did't have too much hassle. Takes me a little longer than 5 minutes, like the dealer said., maybe ten. I haven't had any problems with the pins.
Maybe you have some dirt build up between the body of the tractor and on the faces of the clamps??? I would try a good cleaning with a spray solvent. (Some of those spray lubes hold dirt and dust after a while.) Then lube them up with good anti sieze spray. I have a can of silver anti-sieze spray i use on the backhoe, cylinders, and any moving parts when I put the bh up for a while.

It might be an alignment issue or like you said maybe the bolts are too tight. Sometimes when I put my backhoe back on it goes right on with no problems and other times I have to readjust the whole unit ( a good kick sometimes does it) before the upper links will lock on.

I have had my BX22 a couple of years now, and the loader on and off countless times. Every once and a while one side will not be sitting quite right when I go to attach the BH. All I have to do it tap it with a rubber mallet and it snaps into the correct open position and all is well.

I don't think you can overtighten the bolts. Perhaps you should remove the clamp bolt and make sure everything moves smoothly.

Bandit,

I've had my BH on-off numerous times in the 2 years I've had the BX22. I nearly always have to use a hammer to persuade the right one to open & grab. It is more difficult to make it release too. No problems on the left side. I've tried a variety of lubricants, from wd-40 to Liquid Wrench, & that will make it work a little better, but I cannot count on any carry-over to the next time it is installed/removed.

I've put on my list of things that happen due to the 'cussedness of nature', & go on from there.

I've seen this mentioned on TBN before, & someone replied that the unit was defective. Well, I agree it should work better than it does, but a few light taps with a hammer does not seem excessive. I would not go so far as to say it is defective.

Hope someone posts the solution.

I had the same problem with one of mine on my BX23 and it was under warrenty the dealer had to replace it and all works great now

My BX22 starting acting up on the mounting about 2 months ago and I thought it was just me.

It seemes that the top clamp (or what they are) goes out or disengages but not 100%. So far only once...thank god.

Well, it sounds like the problem is a little more common than I thought. This coming weekend, I'm going to try loosening everything up, and then re-tightening the bolts, clean and lube the linkages, and see if that helps. Looks like the previous owner used a hammer all over the linkages, so this problem has probably existed on this machine for a while.

Can anyone tell me what the Torque specifications are for the large bolt that holds the center of the linkage together? I may not get the opportunity to review the owner's manual, as my neighbor is taking off for a long weekend tomorrow, and I'm sure he's running around dealing with packing everything up. Or better yet, is there a link to a website that has downloads of the the BX owner's manual?

I have the manual on my website to view.

That might help ya. It is for the 23 but for what we need it for, 99% is the same.

Thanks Mike,

I was in the process of sending you a PM, when I saw your post, so I went back in to your web page, and found the manual (I missed it the first time /forums/images/graemlins/crazy.gif) Just found what I think are the torque specs for those bolts. /forums/images/graemlins/cool.gif
