FIGURE 59: PANTOGRAPH DOOR ADJUSTMENT
FIGURE 60: PANTOGRAPH DOOR ADJUSTMENT
Doors can be adjusted by bending the arms as
follows:
1. Open the door halfway up.
2. Install a piece of wood (a 2x4 will do) along
the bottom of the baggage compartment.
Arrange so it rests against the striker pins
and is prevented from sliding further in the
compartment.
3. Install another piece of 2x4 between the first
piece and the bottom of the pivot of the
lowest (or shortest) pantograph arm, (Figure
58).
4. Pull down on the opposite side of the door to
bend the door around the pantograph arm
pivot (prevented from moving by the 2x4).
5. When the door is straight, remove the 2x4's
and check door operation and fit. A
difference of 3/32" (2mm) between both
sides is accepted (Figure 60).
6. Repeat as necessary.

23. DOOR HANDLES

Compartment door handles are non-serviceable.
When a door handle has to be removed,
proceed as follows:
1. Unscrew the four (4) retaining screws;
2. Remove the two (2) wires connecting the
handle
mechanisms.
3. To install a new handle, reverse the
procedure.

24. ENGINE COMPARTMENT DOOR

The engine compartment rear door (Figure 61)
rises in the same way as the baggage
compartment doors and is held open by three
18062
gas-charged cylinders (Prevost # 980024). The
engine compartment opens by lifting a handle
accessed from the R.H. side of the engine
compartment.

When pushed up, the handle pulls on two steel
wires, each steel wire connected to its respective
door latch locking the rear door. Both steel wires
are looped at the release handle and can be
adjusted to proper length to ensure positive
release of both catches when the handle is
raised.

24.1 ENGINE DOOR ADJUSTMENT

As indicated above, the engine door mechanism
is similar to the baggage door mechanism using
a pantograph and 3 gas cylinders to move the
door up and down.
