I removed the cutting head assembly, then the guard. Then removed the screws that hold the gearbox to the spindle housing. And removed it. I then attached the new gearbox to the spindle housing. Making sure that the cable was seated in the gearbox And replaced all of the other parts that I removed earlier.
