Could not find a picture of this installed, I have replaced this spring and it is hard to do. You have to put the straight prong of the spring unto the valve arm, you will see a spot for it to be at, then wind the other end of the spring around until it goes into a slot, then get it all together on the agi housing before it comes apart. Hope this makes sense.

Put on your work gloves. Check the frame size for your mower. It will
either be a 56-inch frame mower or a 76-inch frame mower. When you have
determined the frame size, adjust the tractor's rear wheels to the mower's
frame size. For 56-inch frames, adjust the rear tractor wheels to 56-inch
centers or less. The same rule applies for 76-inch frames.
Back the tractor into a position where you can align its left lower link
to the mower's lift link pin. Attach these two parts together and secure the
connection with the tractor linchpin.
Roll the tractor and adjust the leveling crank until the tractor's right
lower link can be attached to the right link pin on the mower. Use the tractor
linch pin to secure the connection.
Attach the upper link from the mower to the lower hole in the tractor
rocker arm by using the link pin.
Start the tractor. Using the hydraulic control lever, lift the mower
frame assembly slightly and move the mower to the left to allow attachment of
the left stabilizer. Place the stabilizer guide under the tractor's left lift
link. Position the clamp over the link and tighten the nut firmly
Depending on the tractor type, install the clamp plate or push rod
anchor assembly onto the left lower link. Install the push rod on either the
clamp plate or anchor assembly.
Shift the mower assembly to the right to attach the right stabilizer.
Place the stabilizer guide under the tractor's right lift link. Position the
clamp over the link and tighten the nut firmly.
Raise the mower using the hydraulic control, then attach the mower lift
spring to the spring links with the pins that have been provided. Lower the
mower assembly and turn off the engine.
Remove the tractor power takeoff (PTO) cap and connect the splined end
of the mower's drive shaft to the PTO shaft. Secure the connection with the
snap coupler found on the yoke.
Rotate the leveling crank to lower the frame, ensuring that it is
parallel to the ground. Use the leveling crank lock to secure the crank lever.

I have never touched a Kirby vacuum
before and my wife had the same issue. The neutral/drive pedal just fell
out so I figured I would give it a shot to see if I could fix it and
quickly figured out the 3 screws in the bottom plate for the drive
unit wasn't the answer.
I was able to figure things out out after I found
a parts list with diagrams at the follow web site and address:
Vac Parts Warehouse.com
The two parts involved are:
13. Bracket Cam Assembly Neutral Drive
16. Kirby Pedal Cam For Neutral Drive
Here's how to get to a point that you
can get these two parts in/out of the machine.
- Remove bag and fill tube from handle
and main unit
- Remove floor nozzle assembly
- Remove the handle via the two screws
at the handle fork plate (these have loctite on them so needed a
socket wrench with torex bits to get them out).
- Remove the plastic rear scuff plate
vie the screw with the power cord anchor and screw by the Pedal Cam
For Neutral Drive. Note release plastic tab in slot in the center and
lift from the back and then over the base where the handle attaches.
I did not do this as I removed the the
power drive assembly so I could figure out how to put the dive
assembly back together. The pressed on arm that drives the cam
assembly had pulled of the pedal shaft so this also made it easier to
fish out the parts and experiment on positioning the arm in the right spot . I found the arm and a spring washer inside.
I assume at this point you could
loosen the screw (don't remove it, it's the only one with a star
lock washer on it) on the bottom plate that attaches the Bracket Cam
Assembly and slide the Pedal Cam out and a new one in if you can
get the part and replace it. The part was 16. Kirby Pedal Cam For
Neutral Drive G6 558499A at Vac Parts Warehouse.com. The one listed
on the website said it was for a G6 even though the parts listing is
for a G5 so I don't know....
To continue to disassemble and take
the power drive assembly out:
- Remove the 4 screws from the Cover
Shell assembly - the metal top part. You do not need to remove the
hinged Headlight Cap that is attached to it.
- Remove the 4 screw from the bracket
assembly that has the handle attachment and forward/reverse switch.
It attached by two wires. I only disconnect one and swung it to the
- Snap off the the on/off switch and
disconnect from the Actuating Rod Foot Pedal to Power Switch.
- Remove the 3 screw from the bottom
plate of the power drive assembly.
- Remove the drive belt.
- The power drive assembly will now
drop out the bottom.
I just put the spring washer and arm
back on the shaft and reassembled. I'll see how long that lasts
before before buying the new part.
