THE MECHANICAL PROCEDURE MANUAL FOR HUDSON AND TERRAPLANE SERVICE MEN The Hudson Motor Car Company has throughout its existence endeav- ored to build into its products the highest quality of material and work- manship to insure the purchaser economical, trouble free transportation. THE success in this endeavor is attested to by the unusually high percent- age of total cars built since the organization of the company in 1909, which still continue to be operated as motor vehicles. There are recorded, in addition, many cases wherein the age of the vehicle obsoleted it for its original purpose and the engine and other mechanical units have been removed and are being utilized as power units for farm machinery, saw mills, pumps, boats, etc. The Hudson Motor Car Company realizes that even with maximum diligence in design and manufacture, the reputation of its products depends to a large extent upon intelligent and regular servicing and has prepared this manual as a guide and a help to the thousands of men, many of whom for more than 25 years have diligently striven to maintain the performance and reputation, in their respective localities, of Hudson built cars through careful and efficient service. To these men belong much credit for the reputation of Hudson built products and this manual is therefore dedicated to them, The Hudson Terraplane Service Men.
