Case 580b CK Hoe quit swinging

[MasterSplinter]

Oh ok, pictures right from the cow's udder. I like that. I'm not sure exactly what hoe it is either, I took it off something that looked like a 530 or so... and I had to "make" it fit the tractor itself where the bushings and large pins hold the unit on.

If anyone's interested in the 3 pt hitch that I took off the unit, let me know.

I have an OTC 1266 spanner wrench that I use on these type of glands. The last set I did was on a Super M I believe. Some of the case glands have a small screw in the gland locking it into the barrel of the cylinder. I left the barrels in the cylinder and just got the rods out. JJ

I hope you like my home made spanner wrench. It worked just fine!

As for the bolt/rod I will be taking to an engine/machine shop tomorrow and seeing if they can fix the threads on the inside of the rod. I think what happened was the bolt backed out slowly over time, and finally when it only had a few threads left and had a lot of force on it, it pulled itself out and that's when I heard the loud noise.

Still not sure how to measure the 1000 to 1200lb torque to get the bolt into the rod. I'm guessing the last guy didn't either and that's why I have it apart. My father says I can put that much force on it with about a 3 foot bar on a wrench, but that is still no way of measuring. He also suggested using an impact wrench.

Every time I ask him how tight to turn a bolt he always says "Oh about a half a turn before it breaks"

Wow, I'm surprized there's no more damage than what you have, you came out pretty good on this breakdown. I see you managed to hold on to that little disk that goes in the bottom of the bolt hole that the spring sets on.

 

[MasterSplinter]

Atco, That little disc actually stayed in the rod. When the rod went flying out into the snow I tilted it up to drain the fluid and it fell right out in the snow. I thought it was a nickle... so I spent a half hour of digging to find it.

Still trying to figure out how to measure 1000lb force on that bolt. I spose I'll crank it on tight as I can, I know I can't break it! (eat my words later?)

Just ordered a new seal kit for $38 with shipping.

I've never worried much about exact torque on those type cylinders. Just clean the threads of oil with starting fluid and air nozzle, apply some red Locktite to bolt threads, set bolt, and torque it down good with a cheater pipe, you'll be Ok.

 

[capnkel]

To torque that to exactly 1000ftlbs you need either a 3/4"torque wrench and a torque multiplier,or a Hytorq setup.If you weigh about 200lbs,and use 5' of pipe,you should come pretty close by standing on it.

 

[Hardline]

LOL Your spanner wrench looks like it did a fine job. Hey whatever it takes to get the job done. Down here in Texas I am not familiar what all the white stuff is on the ground. That in itself would be enough to make me quit. I hate cold weather. As far as the bolt torque. I just B12 it off really good. Let it completely dry then Red loctite it. Then put it on as tight as I can get it with my 1/2 impact. JJ

I used a 4:1 multiplier with my 600ft/lb torque wrench, big thing is finding a strong anchor point, luckily I had a few handy on the tractor, Vice & workbench won't usually take 1200ft/lbs of torque. should be able to rent a torque multiplier if you can't find a loaner.

how did you end up making out with this? i believe i have the same problem.
