Stand Mixer Pinion Gear

Bought a KitchenAid Pro Series stand mixer from Sam's Club about five years ago. The transmission gears stripped. It is failry easy to replace but you need to replace the worm gear and the pinion at the same time. Make sure all the old grease is removed completely to ensure no old shavings reaming in the transmission housing. Also, if you have a fiberglass transmission housing, inspect the housing closely to indetify any hairline fractures and do not fill the transmission assembly with too much grease becasue you need room for the housing to breathe when the unit is in operation. If you fill the housing too much and tighten it, it "WILL" crack the housing. You want enough gree to keep the asssemnly lubricated but not too much that when you run the mixer that it expands and cracks the housing.
