Super A Lift Arms -- Something else

David Bentley · Mar 29, 2009

I have tried the Big Hammer technique.. It will not budge. I am working on the left side of the Tractor. I got the outer one off & I can see that it was a taper fit with a key. The inner lift arm is the one giving me trouble in removing.. Is it a taper fit as well ? I can see something between the shaft and lift arm that looks like a bushing. Should I just keep on beating it with the hammer ?

Dave, I'm working from a memory that ain't 100%, but I have a couple of pics that may help.

The right fork is cast as one piece with the transverse shaft...

That way, that fork will operate the two keyed-arms on either end of the shaft.
But in this next pic, (and here's where I'm testing my memory), I think the left fork and the left actuating arm are cast one and the same, and work unkeyed and independently of the shaft, (which is how that left fork moves the left actuating arm) and I have arrows labeled #1 to what I'm talking about...

...and I think that's why the pillow block is in two pieces on the left, and one piece on the right, (if you go by the arrows labeled #2), and that's why the actuating arm you are trying to remove won't come off. Take off the outer piece of the pillow block, and I'll bet you'll see your answer. You won't be able to take that left actuating arm off until the inner fork is separated from the piston rod coming from within the block.
Maybe somebody else will chime in and set us both straight!

The left arm rides on the shaft and is held in place by a split bearing (sorta like a connecting rod). Right side bearing is split also I think (been over 20 years) and carries only the shaft. To get the left side inner arm off it will have to be disconnected from the cylinder rod up under the front of the touch control unit. Unless you have midget hands, the whole touch control housing has to come off to get to this I THINK. (like I said, its been a while). You have the hard part done getting those taper fits loose. Just take the whole thing off the tractor and remove the four 5/8 bolts that hold the split bearings on and it will fall apart. HTH.
