Baggage Compartment Doors; Pantograph Adjustment - PREVOST H3-41 Maintenance Manual

SECTION 18a: H3 SERIES BODY

22. BAGGAGE COMPARTMENT DOORS

FIGURE 57: BAGGAGE COMPARTMENT DOOR
There are 6 pantograph doors serving as
baggage compartment doors on the H3-41, while
there are 8 on the H3-45 and the V.I.P
(depending on options, VIP model may have
even more pantograph doors). Each of these
doors is of identical design. A centrally mounted,
key-lockable door handle unlatches the door
which can then be pulled out and raised up in a
path parallel to the side of the vehicle. The door
is held in open position by two fully extended
gas-charged cylinders, giving clear access to the
opening of the baggage compartment.
From its fully open position, the door can be
closed by pulling down on the door panel, and
letting go when you sense the door will close on
its own. The door will easily hinge its way back
in the contour of the compartment opening and
will be held closed by two latches. Each door can
be opened by lifting the centrally mounted handle
to unlatch the door and lifting it all the way up. If
the door does not remain in the fully open
position, one or both gas cylinders on that door
is (are) defective. To test the cylinders, first
support the door in the fully open position with
proper equipment. Disconnect the rod end of
one cylinder and try to retract the rod. If strong
resistance is felt, the gas cylinder is in good
condition and can be reinstalled. If the rod
retracts with little effort, the cylinder is defective
and should be replaced at once. Test the other
cylinder on that door the same way.

NOTE
In case of malfunctioning or in specific
situations, use door stoppers to secure the
door in the open position.

22.1 PANTOGRAPH ADJUSTMENT

WARNING
Park vehicle safely, apply parking brake, stop
engine and set batteries master switches to
the "OFF" position prior to working on the
vehicle.
NOTE
Refer, if needed, to Figure 57 for identification
of door components.
If the door bends when opening or if pantograph
does not function properly, it is probably because
the pantograph arms are misadjusted.
Measure distance between a pantograph arm
end and a straight edge resting on structure.
Repeat procedure for the other arm. The
distance on each side should be equal. If not,
bend appropriate arm until desired measure is
obtained (Figure 59 & Figure 60).
