DESCRIPTION AND OPERATION
Chassis frame alignment
With the vehicle assembled a check for chassis
squareness can be made as follows:
1. Place the vehicle on a level floor.
2. Mark measuring points at approximately the
locations shown, ensure that the marks are
exactly opposite on each side of the chassis
frame.
3. Hold a plumb line against each of the measuring
points in turn and mark the floor directly beneath
the plumb-bob.
4. Move the vehicle and measure diagonally
between the marks made on the floor, if the
chassis is square the diagonals between the
related measuring points should agree within
9,50 mm.
5. Chassis frame dimensional checks can be
made, with the vehicle upper structure removed,
referring to the applicable illustration and
associated key.
