Product Details

McFarlane engineering pays off!

The already improved McFarlane MC0851559-1 motor mount lock washer is now even better. One side is embossed with a surface texture for improved locking strength and to make sure the washer does not slip while tightening. This helps prevent the lock tab from deforming or shearing during installation. It also helps keep the lock tab centered in the lock hole to minimize slack instead of allowing it to rotate to one side during installation.

  • Up to four times the locking power! 
  • Stronger material allows FAA approval to eliminate the standard washer
  • Designed with six tabs instead of two, giving extra locking power 
  • Easier to use!
  • Four each required per engine
