FGT-P-11872 is an oil filter element used in LT-32 gearbox maintenance.¹²³⁴⁵ It is replaced during gearbox oil change and during conversion, and the filter housing cover screws are tightened to 85 Nm when it is replaced.⁶²⁷⁸ The part is scheduled for replacement every 12 months, or at alarm A2140.²⁹⁵

Facts

• The oil filter element FGT-P-11872 must be replaced during the conversion.⁶
• Per turbine, parts and labour include 470 L of Proseware PWG 220, one FGT-P-11872 oil filter element, one PWG 220 label kit, and labour by 2 technicians for about 6 hours.¹
• The filter element FGT-P-11872 must be replaced every 12 months or at alarm A2140, and breather FGT-P-11880 must be replaced every 12 months.²
• During oil change, the filter element FGT-P-11872 is replaced, the magnetic plug is inspected, and filling is only through a filter cart with a 10 micron element.²
• Alarm A2140, Gearbox oil filter differential pressure high at 2.5 bar, can be caused by a clogged filter element or cold oil; the action is to replace filter element FGT-P-11872.⁹
• One oil filter element FGT-P-11872 is required.³⁴
• The filter element FGT-P-11872 is replaced and the filter housing cover screws are tightened to 85 Nm.⁷
• Gearbox oil filter element replacement task MP-GBX-02 uses part FGT-P-11872, is scheduled every 12 months, and references SOP-GBX-010.⁵
• The oil filter element FGT-P-11872 is to be replaced during the conversion.⁸
• After switching from PWG 320 to PWG 220, oil filter element FGT-P-11872 is to be changed a second time after 500 operating hours because loosened deposits collect in the filter.¹⁰
