Hudson 480-490 Series Service Manual page 4

II
The series 480 and 490 Hudson is built of a completely new principal and design, and is not just another
motor car. The "Monobilt" body and frame construction differs greatly from the conventional motor car
employing separate body and frame units. Naturally being so totally different, a new approach to the repair of
body damage is necessary. These differences, however, do not make the repair job more difficult or more
costly to complete. In many instances the time required on a specific operation is less than that required on
previous models.
Once you are completely familiar with the Monobilt body and frame construction of the 480 and 490
series Hudson, when you have learned the placement of all of the various parts and assemblies and how they
fit together to make the rugged and sturdy Monobuilt all steel unit, then you will go about each job with
complete confidence.
The information contained in this body manual is to be used as a guide for servicing the 480-490 series
Hudson.
The manual has been divided into four parts:
Part one - includes technical information, model designations, body paint color code, estimating and
