If you hit the garage door opener and the motor runs but the chain doesn?t turn and the door doesn?t open then this is likely what you?re looking for. Buy these 8 nylon drive gears and install them yourself in 20 minutes. Keep a few spare gears for your other overhead door, your neighbor's garage, etc.

The door opener manufacturers want to sell you a $40 repair kit containing parts to repair one gear. The local overhead door repair shop wants to replace one gear and charge you $120-150 for parts and a service call.

You can do it yourself for less than $10 per gear and 20 minutes of your time by buying this brand new American-made nylon replacement gear.

For directions on replacing the gear yourself, click the link below. You will need gear grease which is required during installation. An inexpensive small tube of all-weather lithium grease from your local hardware store is perfect. White lithium grease is best; it doesn?t solidify in the winter cold or melt in the summer heat. A small tube (1oz or 1.5 oz) is enough to cover the gear. Check our other listings, we have the perfect size tube of Permatex brand White Lithium Grease and it?s a lot cheaper than the big box stores.

If you would like to pay with a company check, let me know by email. I'll ship the gears the day your check arrives; no need to wait for it to clear my bank.
