The main steps to adjusting the transmission is taking the vacuum apart to be able to get to the transmision. The following steps are how to take it apart.

Remove the Powerhead To do this you will select your carpet height adjuster to its highest settings. Then spin the belt lifter so the two red arrows are pointed at each other. Then disconnect the head and take it off. Side note - when you are done and put your head back on dont forget to realign the arrows to green on green.
Kirby Vacuum Remove the bag and handle Right where the handle goes into the actual vacuum it snaps out. To unsnap the handle their is a button on the back of the handle right at the base where it goes into the vacuum. To take off the bag put your hand under the boot mini emptor (plastic part at bottom of bag) and pull away from the vacuum and it snaps off. That is how you take off the handle and bag.
Kirby Power Switch Remove the trim around the Pivot handle The next step is to remove the trim around the pivot handle (where the handle snaps in). The first thing you want to do is to undo the screw at the bottom of the trim. The screw is located right above the transmission switch. Then you want to remove the screw that holds the cord under the trim. When that is off you want to unsnap the trim buy grabbing the bottom of it and lift up and at the same time push toward the front of the vacuum. The trim then comes off.
Kirby Vacuum Kirby Repair Remove the Metal Body With the powerhead and rear trim removed the 4 screws that remove the Metal body are now visible. First we remove the 2 on the rear of the metal that were covered up by the trim. Once those are removed we move to the front of the vacuum and remove the two remaining screws that are holding on the front of the trim. With the 4 screws removed now you simply lift the Metal body off of the vacuum.

With the completion of this step the vacuum is taken apart as far as we need it to be. Now the motor, transmission. and other main parts of the kirby vacuum are exposed.

Remove the pivot assembly and casing OK here we are going to remove the 4 screws and remove the entire casing and pivot assembly. This will open up the machine so we can work on it. REMEMBER when you are putting everything back together to make sure your linkage to the transmission is properly engaging. Also when pulling off the case their are 2 wires you will have to remove to have it fully off. REMEMBER wire order so when it goes back together it is done right.

Remove kirby Switch fasteners We start with removing the foot pedal (where your foot turns the vacuum on and off. Then we remove the linkage between the foot pedal and the power switch. It removes from the powerswitch by swinging it all the way up towards the vacuum and then pushing down. Then we remove the screw that holds the kirby power switch to the vacuum
Kirby Vacuum schematic Wiring

Now we work on the wiring their is 3 wires that we want to remove. For this procedure I usually use a needle nose plier. You can go ahead and pull the 3 wires out of the switch. VERY IMPORTANT - Remember where they go and in what order. One of my first times in exchanging a switch I wired it incorrectly and sent it to a customer. When the customer recieved it the vacuum ran backwards! Lets just say they were not to amused :) With the wires out we are now ready to remove the switch.

 

Kirby Vacuum Power HEPA Removing the Kirby SwitchThis next step is going to take some common sense and instinct. I cant describe everything but you can figure it out. So all the fasteners and wires are removed now it is time to take it out. First we pull the whole switch back about an inch and a half. Then we pull it up in the direction of step 2 shown in the pictures. If their needs to be some more clearance push the two saftey switches down for more clearance.


Now the switch is out. We simply reverse the process. Sometimes to get the switch in and out their has to be some wiggling and manuvering to get it in and out. So now you put the new switch in and put the wires back (not so easy sometimes) and the screw. Then you reconnect the linkage to the foot pedal. When you put the pivot assembly back on dont forget to align up the linkage to the transmission so the transmission works correctly. Then put the rest of the vacuum back together and you are done. This is a good time to congratulate yourself, this is one of the hardest repairs to do on a kirby :)
