Sloppy joints

[BuddyBear]

Hey folks,
I'm new to the world of backhoes and such, so please help me out if you will.
I've just aquired a Case D100 hoe and it is about as loose as my ex-wife's morals. The pin at the base of the boom that hinges the up and down motion is the worst. This means that hitting the intended ditch takes a while. I haven't disassembled it yet, but I have a feeling the hole is going to be wallared out. Do these joints normally have bushings, or can I machine the hole larger and install a bushing?

Thanks in advance

"wallared out", yep it happens. You can go to a CASE site like falconpower.com and look at the CASE parts link. You type in your model and it displays a 'blow apart' diagram. you can also select the part #'s etc and even print out a list! pretty cool. And, falconpower in Phenoix, Az. carries CASE and aftermarket parts....sl

They usually have bushings but if the bushings are left too long, the whole bushing retainer has to be cut off and a new set carefully welded back on. It can get pricey if all pivots need to be done. Hopefully all you need is new internal bushings. Dave

As another post suggested if it"s sloppy lose then it had a bushing at one time that"s now worn out. If the holes are still OK then replacing the bushings with factory ones isn"t a big deal. If the holes are worn out and egg shaped then your best bet is gonna be to have the holes line bored back round. Depending on the amount of material around the holes as to the best way to go about this. Sometimes you can bore the holes oversize and either make custom bushings to fit the hole or if you can get a thick enough wall simply sleeve the oversize hole back down to the factory size. Often boring oversize and sleeving like this is quicker and easier than having to set up and weld the holes up til their "round" again and then boring them back out to size. Like I said it depends on several factors as to what"s the cheapest and easiest route to go so if you have to do this make sure you find someone reputible and then follow their advice. Good luck.

Thanks to all ya'all for the help. The falconpower web site is a life saver. More people should know about it.

There is a part available called an Expander that eliminates line boring, rebushs the joint and can be done on site.

Thanks for the info. From what I could tell, the expander will only take care of the slop in the boom lugs. The bushings in the swing tower (I didn't know it was called that when I started this) are also worn. I didn't see an application for that in the ExpanderSystem. Is there one?

I have learned it will cost about $150 for four bushings and a pin. As a man of meager means, I've decided to make them. I have slightly more time than money. I've scrounged and begged the material so the only cost will be time. From past experence, I will probably end up buying them.
