B7100 Centering arm bushing.

[torch]

Part number 070, below.

I'm getting a lot of slop in the arm (060). Enough that it shifted sideways enough the centering notch on the bottom of 010 ended up riding on the circlip (130) instead of the bearing (110).

Is this as simple as removing the spring (030), bolt (100), slide the arm off and swap in a new bushing? Or is there a "gotcha" when you remove bolt 100?

Yes I think you have it, it's been a while since I dove into one of these.

Thanks.

It just seems too easy.

Replacing item 70 should fix your problem. If there is excessive wear on 10 or 60, you can replace 120 with a washer that has a larger diameter that the bearing(110).
hopefully that makes sense. You may find 70 is gone and it is just metal on metal. If I remember right, 70 is a snug fit on 80. And there is a access panel on the side of the tractor, for just such a repair.

No access panel on mine. There is a small hole in the side of the frame adjacent to the bolt, but everything else has to be done from underneath.

Yeah, the panel covers the hole… not an easy area to work in. I think I ended up unthreading the tension bolt item 170 to be able to reattach the spring to item 60.

Oh, yes, there is a cover on the top that hides the tensioning bolt. I thought you were referring to the side of the frame, where the mounting bolt hides. Mine just has a small hole in the frame in line with the bolt. No cover, just partially obstructed by the brake rod:

Thinking back...removing 100 is easy, no surprises, but 80 is eccentric, it is used to adjust the pedal for forward and reverse movement. while it is on jack stands you can adjust pedal travel/tire spin by turning 80 with a standard screwdriver and locking it in position with bolt 100.
