Engine nose gearbox oil jet filter(s) removed
Oil jets on engine nose gearbox are not interchangeable with each other. To prevent damage to engine
nose gearbox, do not intermix or swap oil jets.
This task is applicable to outboard, top aft, and top forward oil jet on left engine nose gearbox and

Removal and installation procedures for outboard and top forward oil jet are typical for either No. 1
or No. 2 engine nose gearbox.
The top aft oil jet on right engine nose gearbox has been replaced with a gear mesh plug due to
addition of an inboard oil jet. Do not remove gear mesh plug.
