Putting the flat washers in the wrong place when reattaching the ramp chains after maintenance could end up damaging the pulley housing.
There are two flat washers, NSN 5310-01-510-5385. Don’t assume that both washers go on each side of the connector. If you put a washer on each side of the connector, the connector hits and damages the pulley housing as the ramp is closed.
There’s an easy fix. The ramp will raise and lower smoothly, without anything getting crunched, if you put both washers on the inside of the connector just like it says in TM 9-2353-311-13&P in IETM EM 0269 (Sep 16).
Place both washers on the inside of the connector
