Hitachi Excavator- Swing motor gearbox leak ... 10000 hrs that I am thinking the seal on the swing motor reduction gearbox went out. ... but a friend that works on construction equipment said to check the swivel manifold.
You'll probably need to replace the motor in the swing. Most of these types of swings work off a motor with a plastic gear attached, and the inside of the gear gets worn down over time. The motor still gets power and still turns the gear, but the gear doesn't have the grip that it used to so the swing doesn't move as much (especially with a baby in it).
In some models, there are swing and sweep motors. Swing will work the vent up and down. Sweep or air flow motor will work for louvers left to right. If sweep motor not works replace the motor. If no sweep motor option, you have to direct by manual only. Be care ful, when you are doing manually, switch of the unit. Thanks.
It's likely the motor gone bad. The contacts inside the motor can get burnt out and prevent the motor from turning. Did you buy the swing brand new, or was it used? If you bought it new you should return it for a refund.
I had the exact same problem the motor worked fine but when we took it apart the gear inside was stripped. i hate saying it but best thing you can do is buy a new swing. i personally recommend http://www.toysrus.com/product/index.jsp?productId=3420749&camp=PPC%3A204318389. its a little bit high but so worth the money. my 8mo old baby girl loves it. it also has a AC adapter so no more batteries and an ipod hook up as well so you can pick what music you want your baby to listen to. best of luck.
