ADJUSTMENTS
Door Assembly in Cab Opening
Door up and down adjustment in cab opening is provided
by means of floating hinge cap screw tapping plates within
door framing. Horizontal slotted cap screw holes in cab
half of hinge assembly provide the in or out adjustment of
door.
Only the upper portion of door can be adjusted "fo re”
and "aft" with the adjustment being at the upper hinge.
NOTE:
Before making door adjustments al­
ways remove striker plate assembly (View F,
fig. 121) from the cab lock pillar.
In addition to the door lock striker, rear of door is sup­
ported in cab opening on two other strikers, one at top of
door and the other at bottom of door. Lower striker,
which is spring-loaded and self-adjusting is mounted to
bottom of door frame as shown in View D, Figure 121.
The adjacent striker support is mounted on door ledge of
cab as shown in View F, Figure 121.
Upper striker and striker support is employed at top of
door to restrict the up and down movement of door in cab
opening. See Views A and C, Figure 121. A fiber shim
(approx. 0.094" thick) is installed between cab and striker
support (View A, Figure 121) to provide adequate clear­
ance between top of door and cab.
The position and purpose of door upper and lower
strikers must be considered when making door adjust­
ments.
To Reposition Door Up or Down
NOTE:
Door raised adjustment is limited by a
striker at top rear of door (View A, fig. 102).
The striker support at cab is mounted over a
shim which will usually provide the proper
clearance at top of door; however, shim can be
removed or another added as desired.
a. Loosen hinge-to-door cap screws slightly. Re­
position door on hinges to provide equal clearance
around perimeter of door in cab opening.
NOTE:
Access to one cap screw at door upper
hinge is gained after removing plug from door
inner panel. Use pointed tool to remove plug.
b. After satisfactory adjustment has been obtained,
tighten hinge cap screws firmly. Open and close
door to check operation. If necessary, repeat ad­
justment. Install hinge cap screw access plug in
door inner panel after making final adjustment.
c. Install striker plate assembly on cab lock pillar
as directed under "Striker Plate Adjustment."
To Reposition Door Fore or Aft
NOTE:
Only the upper portion of door can be
adjusted fore or aft. This adjustment is made
at the upper hinge. No means for this adjust­
ment exists at the lower hinge.
a. Loosen upper hinge-to-door cap screws slightly.
NOTE:
Access to one cap screw at door upper
hinge is gained after removing plug from door
inner panel. Use pointed tool to remove plug.
Lift upward or pull downward at rear of door to
tilt upper portion of door fore or aft as desired.
b. Tighten hinge cap screws firmly after making ad­
justment. Open and close door to check opera­
tion. Repeat adjustment if necessary. Install cap
screw access plug in door inner paneling.
c. Install striker plate assembly to cab lock pillar
as directed under "Striker Plate Adjustment."
To Reposition Door In or Out
NOTE:
Horizontal cap screw slots exist in cab
half of hinge assembly to permit this adjustment.
See Views B and E, Figure 121.
The outer surface of door when properly installed
should be flush with adjacent panel surfaces of cab (fig.
122). If necessary, reposition door as follows:
a. Loosen slightly, all cap screws which attach hinge
half to cab pillar.
b. If door is to be brought outward from cab opening,
apply pressure at door hinge area from inside
cab. If door is to be moved inward, apply pres­
sure on door outer panel at hinge area.
IMPORTANT:
Excessive pressure will damage
door paneling.
