  "textContent": "A gear reduction (100) includes a sun gear (104) that engages a plurality of planet gears (106A, 106B, 106C) mounted on a carrier (110). The planet gears (106A, 106B, 106C) are engaged with a ring gear (108). The ring gear (108) is fixed against rotation such that rotation of the sun gear (104) causes rotation of the planet gears (106A, 106B, 106C) to cause rotation of the carrier (110). There are spray bars (120) positioned circumferentially between adjacent ones of the planet gears (106A, 106B, 106C). The spray bars (120A, 120B) have jet openings (122), such that lubricant can be passed directly onto teeth on the sun gear (104). One of the side faces (210, 212) has a plurality of windows (140) such that oil can be scavenged. There are side surfaces between the plurality of windows (140) that do not have an opening. A gas turbine engine (20) and a spray bar (120A, 120B) are also disclosed.",
