CAB DOOR

The cab door assemblies are similar except for the
hinge side. Each is hinged on the rear edge with a
heavy duty hinge. For repairs on the door latches or
window controls it is usually better, but not neces-
sary, to remove the door from the cab and lower it to
the floor for service.

Removal

1. If overhead space is available, raise body to
allow access to door with overhead hoist.
Secure body in raised position with safety
cables.
2. Lower door glass far enough to allow insertion
of lifting sling when door is removed.
3. Remove door panel for access to power win-
dow motor harness connector. Disconnect
motor and remove cab harness from door.
4. Remove the retainer clip and bolt clip from the
travel limiting strap.

5. Insert lifting sling through door and attach to
hoist. Remove cap screws (a swivel socket
works best) securing door hinge to cab and lift
door from cab.
6. Place door on blocks or on a work bench to pro-
tect the window glass and allow access to inter-
nal components for repair.

Installation

1. Attach sling and hoist to door assembly, lift door
up to the deck and position door hinges to cab.
2. Align door hinges with cab and install cap
screws securing door to cab.
3. Attach the travel limiting strap with the bolt and
clip removed previously.
4. Reconnect door harness to receptacle mounted
in the cab floor.
5. Verify proper operation of power window and
door latch adjustment.
6. Install door panel.

Door Adjustment

If adjustment is necessary to insure tight closure of
door, loosen striker bolt in the door jamb, adjust, and
retighten.
A rubber sealer strip is mounted with adhesive
around the perimeter of the door assembly to
exclude dirt and drafts. This sealer strip should be
kept in good condition and replaced if it becomes
torn or otherwise damaged.
