9. Using a 10-inch adjustable wrench, retighten the locking nut on the upper retainer; do not over tighten the
If the ½-inch diameter pins in the latch side plates, that secure the
retainer and catch are separate pins or are an integral fixed pin one-
piece construction, then staking is not necessary.
10. Determine if the pins are loose and can fall out through the side plates as follows:
Using a flat surface, a 3/8-inch diameter or less pin or bolt, tap gently with a hammer on each end of
the ½-inch diameter latch pins through the side plate holes.
If the pins are loose and can fall through the side plates, stake as follows:
Use of proper eye protection should be used for protection against any
metal chips that may be dislodged when staking pins. Flying debris may
cause injury to personnel.
Place the assembled latch assembly on a solid level surface.
Place the tip of the center punch approximately 1/16-inch from the edge of the ½-inch diameter
hole in the side plate.
Strike the punch with a hammer to cause a 3/32-inch dimple and a slight flow of metal towards
the inside edge of the hole which will then retain the latch pin as required.
Repeat the stacking at four places, 90 degrees apart from each other.
Recheck for loose pins as described in step a. above.
