We now have access to the two shaft nuts that have to be removed to allow for removal of the primary chain, clutch and front rotor/sprocket assembly. You will need an impact wrench and a couple large sockets to get these off. The impact/ air wrench takes advantage of the inertia of the motor and basically bangs the nuts off rapidly without you having to hold or jam the assembly while you muscle it off with a torque wrench. There is one thing to note - the transmission main shaft nut is a counter clockwise thread, so don't beat on it all day in the wrong direction trying to get it off.

For this project, the rotor was placed back on the front shaft just to keep it somewhere clean, but you can take it off for working in this area. It's magnetic and wanted to stay on the stator, so we gave it a good tug and it came right off.

What you are looking at in the photo above is the stock shifter prawl, detent plate, detent and detent spring. The stock plate is held on with a spring clip. As you will see later, the Baker model is held on with a screw.

Remove the detent plate, shifter prawl and detent spring (loose in the photo above) and get ready to unbolt the four bolts on the trap door.

Once you unbolt the four bolts holding on the trap door, the entire cartridge assembly is removed by pulling it toward you. The stock unit is above. Note the door thickness and webbing on the cast piece.
