Overview – General Parts LOCK;DOOR A055X778 Series
If you run Cummins cab and enclosure positions as the door lock, the Cummins LOCK;DOOR A055X778 and its series variants give you flexible sourcing without compromising fit.
Parts Characteristics
A door lock that secures the cab or enclosure, holding the panel closed against vibration and access. It carries the latch and the catch, so a true, positive lock keeps the door shut and the contents safe.
Applicable Models & Applications
Used at Cummins cab positions specifying this door lock (series). Match the actuator, the strike and the mounting against your old lock – door locks differ in how they latch and release.
Maintenance & Replacement
Inspect the lock for a slack latch and a worn strike at every service. A lock that has begun to rattle opens on the move, and the open is what loses the panel.
Replace the lock rather than force a bent one. A lock that no longer catches leaves the door ajar, and the gap is what shakes the cab.
Confirm the strike aligns with the latch on fit. A lock mounted off the mark either will not catch or will not release, and both stop the operator.
Keep the correct door locks for your model on the shelf. They are cheap, they protect the cab, and they are exactly the part missing when a door needs securing today.
