  • Adjusting Arm Work
  • My adjusting arm is frozen. Attempts to free it on the tractor isn't working. Therefore, I need to remove it. Should be an easy enough job, right? Well, not for me it isn't. It took forever to get the nut off the bolt where the adjuster is connected to the lifting arms; even using a wire brush on an open toe grinder. I got the nut off with some effort without messing up the threads but I can not get that "bolt"; I don't know the correct term, to come out. I sprayed with penetrating oil, tapped, use a punch on the end of the bolt, reversed the bolt and tapped, heated with a propane torch and tapped, more oil and tapped and it isn't bulging. So, before I get a larger hammer; is there a method to removing it? I use caution because I don't like breaking things out of ignorance.

  • Both of mine had grooves worn into them from the lift arms wearing on the underside of the bolt shoulder. It felt like they were frozen when it was actually hanging up on the edge of the groove. Try lifting up on the arm while you drive out the bolt.

  • I gave up on removing the pin; I had a two jaw puller on it and I was afraid I was going to break the fork. I can plough with the leveling not working and return to it after I turn the gardens.

  • Is that pressed in? If so then I am wasting my time trying to remove it without a press and all I am accomplishing is wasting propane and buggering up the nut.

  • You might need to heat it hotter than a propane torch can heat.

  • You are on the right track but may need more heat and a bigger hammer. time is your friend, it takes a while for the penetrating oil to soak in. If you are in hurry use a BIG hammer with support on back of arm. the bolts are available, just replaced one on one of my 8ns.

  • As said, more heat. Paint still there means it has not been hot enough, by far.

  • Re: Adjusting Arm Work
  • OK. I may not have the heat source needed then. All I have is a propane torch. I will continue to try. I would really like to be able to adjust the lift; especially when I am on the slope. Thanks everyone.

  • Unless the internal threads in that lower piece that is pictured are gone, then you probably don't even need to remove that part. Just screw the upper part out of it.

  • The adjusting arm is frozen; won't turn. The gear box at the top is free. I tried freeing it on the tractor but no go. I figured if I can get the adjuster off it will be easier and if it needs to be replaced then it needs to be removed. I didn't think it would be that hard to remove the bolt/pin at the bottom. I will continue to work on it and if need be call my BIL to come over and give me a hand.

  • The threads were stripped on the upper shaft on the last one I worked on .Dont pound on the nut.Its a lock nut.Always use a new regular nut to hammer on.Take the top pin out an see if a stilson wrench will turn the shaft.You can replace just the top shaft.The joint is probably rusted tight from lack of grease.Regular greasing will push the dirt out.You can see water squirt out of ball joints when greasing equipment.Extra grease can be wiped off with a rag, rust cant.

  • Re: Adjusting Arm Work
  • I may have to remove the lower lift arm (is that what it is called) and take everything over to my BIL; he has proper tools, a press, etc. I may have to replace the leveling unit but I am hoping I can get it free with a little help from BIL. Noted on the nut; thanks.

  • Re: Adjusting Arm Work
  • Have you tried spraying a lubricant like PB BLASTER down the thread shaft? Is the top half bottomed out on the bottom half? There is a grease Zerk on the adjusting arm/leveling crank to keep the threads lubed. The problem with grease is it is a magnet for dirt. Once dirt gets onto threads, it makes it hard to crank. If the crank hasn't been greased in along time, the grease has hardened and turned to wax. A tell-tale sign of that is when you try and pump grease in with a grease gun, you get resistance and it won't pump. Try spraying a penetrant oil onto the thread shaft several times a day and then maybe use a good pair of Vise Grips and/or a large set of Channel Locks to try and separate the two halves. I'd try this before attempting to remove the entire lift arm. I do not like whacking things with a hammer -a good way to crack or break things. Propane is not hot enough to heat steel castings. You'd need a good welders torch.

  • Re: Adjusting Arm Work
  • Yes, I took the grease fitting out and have sprayed a penetrating lubricate in that hole. I see it dripping out the bottom at the fork. I didn't know that rust could weld something that tight. I went through a bad time after Mum died where I didn't take care of things; now I am paying the price so to speak. If I can't free it, I am going to remove the lower lift arm and take everything over to my brother-in-law that has a full shop (he restores muscle cars; mainly Cameros) and has a wide range of tools and equipment to work with. He may even have a propane torch. Yes, I only lightly tapped to help the penetration oil to get in the nooks and crannies. I know how easy it is to crack cast iron. Thanks for the info.

  • Would MAP gas be hot enough?
