The Fabrikam FGT-3200 is a three-stage gearbox used on Litware LT-32 turbines, with one planetary stage followed by two parallel helical stages.12 Its rated input torque is 2,410 kNm and its dry mass is 21.6 t.2 Only the lubricant listed in Table 4-2 is approved for the FGT-3200 gearbox, and lubricants of different brands or viscosity grades must not be mixed.3

Facts

  • The bulletin applies to LT-32 turbines delivered in CCV configuration with Fabrikam FGT-3200 gearboxes and to LT-32 standard turbines at sites where ambient temperature regularly falls below -20 °C.4
  • The document applies to LT-32 turbines of all variants with the Fabrikam FGT-3200 gearbox.1
  • The LT-32 uses a Fabrikam FGT-3200 three-stage gearbox with one planetary stage followed by two parallel helical stages.2
  • The FGT-3200 gearbox rated input torque is 2,410 kNm and its dry mass is 21.6 t.2
  • Only the lubricant listed in Table 4-2 is approved for the FGT-3200 gearbox, and lubricants of different brands or viscosity grades must not be mixed.3
  • The asset is the WTG-07 main gearbox, a Fabrikam FGT-3200 with serial FGT-3200-18-07752.5
  • The procedure applies to WTG-01 to WTG-12 with Litware LT-32 CCV turbines and Fabrikam FGT-3200 gearboxes.6
  • The incident concerns WTG-07, serial LT32-19-0421, with gearbox FGT-3200-18-07752.7
  • All turbine entries are Litware LT-32 CCV turbines with Fabrikam FGT-3200 gearboxes, Hub height (m) 92, and Rotor diameter (m) 118.8910111213141516171819
  • FGT-P-22328, the HSS bearing on the generator side for FGT-3200, is a critical item below minimum stock: 0 pc on hand, minimum 1 pc, reorder quantity 2 pc, and 2 pc on order under PO-76994 for expected delivery on 2026-09-25.2021
  • The deck is about the Fabrikam FGT-3200 in the Litware LT-32 and is dated October 2025.22
  • The configuration records checked for Quellmoor Ridge Wind Farm showed that all 12 turbines, WTG-01 through WTG-12, were delivered as LT-32 in CCV configuration with Fabrikam FGT-3200 gearboxes, so SB-LWS-2025-07 applies to all 12 turbines.23
  • Superseded: The procedure applies to WTG-01 to WTG-12, specified as Litware LT-32 CCV turbines with Fabrikam FGT-3200 gearboxes.24
