(b) If you make a decision to use two square steel plates and a tow-bar, do these steps: - put a square steel plate in position in front of the NLG wheels, - apply a thick layer of COMMON GREASE (Material No. 04-004) or COMMON GREASE (Material No. 04-022) to the upper surface of the square steel plate,
NOTE : Do not mix Material No. 04-004 with Material No. 04-022.____ You can use Material No. 04-022 as an alternative to Material No. 04-004. Clean and degrease the parts before you use Material No. 04-022. - put the other square steel plate in position on the top of the greased steel plate, - move the aircraft and put the NLG wheels in position on the greased steel plates (Ref. TASK 09-10-00-584-002). - connect the tow-bar to the NLG leg, - fully turn the NLG wheels to the right with the tow-bar.
