This gear set includes every gear and shaft (not shown in picture) required to "rebuild" the 645 and 5645 servos. I have rebuilt this servo twice in two weeks using this kit. There are no instructions, but it's easy enough to figure out how to mesh the gears together and put the servo back together. Don't forget to add a little grease to the gears before sealing up your servo.The three stars are for the completeness and ease of installing this gear set. I have stripped the middle brass gear twice in two weeks, and I don't have confidence that the newest one will last any longer, yet. This set is a bit pricey, and it's not an upgrade from stock. If I strip it again, I will definitely upgrade.If you have a 5645 or 645 servo in a low impact application, I recommend using this gear set to rebuild it when it strips. More likely though, if you've stripped your gears once, you'd be better off upgrading to the karbonite or titanium geared servo options from hitec.

The package was undamaged but missing a gear. The product photo shows 4 gears but I only received 3.

Item got here quickly. But less than one day after installing the gears into my servo, the gears broke. I had to buy another servo from my lhs. I think I might stay away from Hitec.

Fast shipping and perfect factory replacement gears. Took 5 minutes to swap the gears. Now have a great servo again without the cost of a whole new servo!!
