Anybody out there ever have this problem. I am performing a 48 month inspection and the Main Rotor Head will not come off the mast spline, the machine has hung under a crane for 24 hours a day for 5 days now and no movement what so ever. We have applied penetrating oil also, and heat. I have had this issue with Bell medium in the past but not like this one. The MRH was last installed by Agusta 200 hundred hours ago I a sneaky feeling that the Dry film lubricant on the head and mast splines have bonded together rather well. Corrosion not a issue here.
Anybody know where I can get some primer cord
