6.1 Vehicle Structure, Body Security and Condition



Information
Method of Inspection
Reason for rejection
Various typical vehicle structures are shown at figures 1 to 4 in Appendix C, where the shaded portions indicate the important load-bearing parts.

Note: The prescribed areas are those specifically detailed in Sections 2, 3 and 5 of the Manual.

Individual body security defects are not a Reason for Rejection unless their cumulative effect is likely to significantly reduce the overall body security.

The inspection of body condition applies to all vehicles and includes body components such as bumpers, spoilers and mirror housings.























The inspection of engine mountings on front wheel drive vehicles also includes mountings bolted to the gearbox that provide essential support for the engine.
A. Vehicle Structure

1.
With the vehicle over a pit or on a raised hoist, check the vehicle structure for any fracture, damage or corrosion, not within the prescribed areas, which is likely to affect prejudicially the correct functioning of the braking system or the steering gear.

B. Body Security (applies to vehicles with separate bodies only)

1.
Examine the following items for presence, security, fracture, distortion, excessive wear or damage:

a.
all fixings (e.g. brackets) securing the body and its supporting members to the chassis

b.
all fixings (e.g. brackets) securing the body to a sub-frame or supporting members, and all securing bolts, rivets or welds for all the above fixings.



2.
Check the condition of the body and chassis in the vicinity of the mounting points.







C. Body Condition

1.
Examine the body work for excessive corrosion or damage resulting in sharp edges which are likely to cause injury.


D. Engine Mountings

1.
Check the engine mountings for presence, security and condition.











E. Steps and Stairs (Class 5 only)

1.
Check the passenger entrance and exit step(s) for security and condition.
2.
Check that any retractable steps operate correctly.
3.
On double deck or split level vehicles, check the presence, security and condition of the stairs.
1.
Any deliberate modification, excessive corrosion, damage, fracture or inadequate repair not within a prescribed area which adversely affects braking or steering by severely reducing the strength or continuity of a main load bearing structural member.

1.
a.
Excessive displacement of the body relative to the chassis which might lead to loss of control of the vehicle when driven

b.
insecurity of the body or its supporting members to the chassis so that it is clear that there would be a danger to other road users.

2.
Any deliberate modification, excessive corrosion, damage, cracks or inadequate repair of a load bearing body or chassis member which seriously affects its strength within 30cm of the body mountings.

1.
A sharp edge or projection, caused by corrosion or damage, which renders the vehicle dangerous to other road users, including pedestrians.

1.
a.
An engine mounting missing or seriously deteriorated resulting in excessive movement
b.
an engine mounting bracket:

. missing

. insecure, fractured or damaged to the extent that it is likely to fail.


1.
An entrance or exit step or its anti-slip provision:

. insecure

. damaged or deteriorated to the extent that it is likely to be a trip hazard or cause injury.

2.
Retractable step not operating correctly.

3.
a.
A stair missing
b.
a stair or its anti-slip provision:

. insecure

. damaged or deteriorated to the extent that it is likely to be a trip hazard or cause injury.
