Emergency Exit Side Latch Replacement - (For small buses):
It is recommended that a special field replacement kit be used for this work.
Latch Replacement:
Release the latches and open the exit section. Using a suitable Phillips head screwdriver, remove the screws holding the latch to the exit frame. Replace the old latch with a new one form the kit. Using a hex driver, place a new hex nut on the back of each screw and tighten securely. Close the exit window and check for proper operation.
Catch Replacement:
Unlatch and open the emergency exit window. The latches engage with catches n the back frame, which are held in place with two rivets each. Using a .128" power drill, remove these rivet heads. Using a 7/64" diameter punch, carefully remove the rivet body and catch. (IF THE WINDOW HAS NO STIFFENER, GO TO "NO STIFFENER" BELOW). Place the new catch on the stiffener and align the holes. Rivet into place with the long silver color rivets in the kit. Close the emergency exit window, close the latches, and verify proper operation.
No Stiffener:
Discard any spacer that may be present. Place new catch and stiffener on back frame, align holes, and rivet into place with the long silver color rivets provided in kit. Center punch and drill .128" holes 1 1/2" above and below the existing rivets. Secure with the short black rivets provided in kit. Drill two holes through the back frame and the other leg of the stiffener, at the height of the first holes. Secure this leg with the short black rivets provided in kit. Close the emergency exit window, close the latches, and verify proper operation.
