Whirlpool top load, washer, transmission gears
Both belt drive and direct drive transmissions used to machined, steel pinion gear, the other metal gears were cast iron.
Neither design ever had any trouble with gears except the pre-1964 transmissions as pictured and reply number 36 the pinion gear used to tear the teeth off the first reduction cast gear whirlpool, beefed it up in 1964 and we never saw problem after that.
Plastic gears are usually stronger and last longer than cast-iron gears, that’s why Maytag used nylon for the pinion gear in their automatic washer transmissions, which never failed in normal use of the machine.
