Case 770 Broken front axel joint...HELP

Midalake · Sep 24, 2015

I was trail mowing when the front tire broke through a small rusted culvert. Put the bucket down lifted the tractor and inched out. Thought everything was ok then in about a half mile I put the bucket down and the whole front end started to move.

So the large cast front mount is cracked up and destroyed. I have only a few pieces of it. The good news is I had down pressure on the bucket and it looks as if the rear mount and the tie rod arms and controller look good.

Questions?

Has this happened to anyone else and how did you fix it?

It looks as if this piece bolts off the tractor? Can someone steer me where i might find one?

Is this a weak spot on the tractor and is there a way to fab a stronger fix with the broken piece I have?

Thanks for all your replies in advance....PS I am just sick...

No not a "weak" point 90% of people grease them very little and they wear thin,, the pivot castings are available aftermarket from a couple places,, this site may even have them,,, this part carries all front weight and with a loader that triples at least the carry weight, after 40 years these need replaced

Long before it can wear thin, there is a bushing that can be replaced. Cheap compared to the casting.

That said, loaders are hard on front ends.

I agree completely,,,, sadly I have never seen one in my shop that could be fixed with a bushing as they are long wore through

Thanks for all the replies. Yes there is a loader on my tractor. The new parts are on the way.

Thanks Dave

I beg to differ a bit with other posters. I as a dealer have seen many of those bolsters broken. The bolster allows for very little osilation, and crossing ditches diagonally or droping into a hole with one wheel, plus the lateral pressure would pry the bottom rite out of them. We and my neighboring dealer R.Imps. had a machine shop build 3 of the bolsters at a time out of STEEL. When our joint inventory dropped to 1, we had them make 3 more. I don't remember how many we had made total, guessing 3 dozen.
Both of our 770s have the steel ones on them, and neither had loaders mounted.
You are lucky the front axle didn't pop out of the bolster and fold under the belly of the tractor and twist the wishbone. BTDT

"beg" and differ all you want Bro,,, LOL,,, I have changed Many of them here to but like I said grease worms get them too,, I have yet to see one break that was not worn through,,, my 770 has over 10,000 hours and still the factory one is in place,,, she is worn and needs replaced though

I'm on the side of both Tom and Loren here. We didn't have many 770's, but 8,9,1070's were very popular in my area. Tom kinda misses out on the dairy farmer phenomenon, but after running a welding shop for 20 years in a dairy area, I know it very well. Dairy farmers are well known for their ability to destroy an anvil (altho I used different words). Lol I've been called more than a few times to a farm to fix that broken casting, but just brought a replacement since both the case dealers and the local salvage yard stock those castings. They are also commonly worn beyond repair from lack of grease and not replacing those bushings soon enough. So both of you are correct as far as I'm concerned.

jon,, sounds like the way the "Ruffnecks" here (oil field hands) could tear a backhoe into pieces,,, my Dad always said they could tear up a anvil with a rubber hammer",,, I was just giving Bro some static,,, called him while I was posting lol

A little background - Milk cows were the motivation I needed to go to college.

I have always said my brother could wreck an anvil with nothing more than a feather.

You know I think you have it right Adirondack Case Guy. The angle of the whole assembly was too much stress.

Do you happen to have one of those steel one's laying around?
