FOREWORD
This manual is intended as both a guide and a reference book in the complete servicing of Harley-Davidson Mili- tary Pattern Motorcycles.
The book is divided into two major sections:
1, Operation, Inspection and Preventive Maintenance.
2. Workshop Procedure.
Section One covers correct maintenance of the vehicle to provide best operating efficiency. Section Two covers servicing methods which have been grouped according to major assemblies of the vehicles. Under each major unit the operations have been carefully outlined and nu- merous action illustrations with proper tools in use have been introduced to clarify the text.
The more satisfactory and dependable performance of one motorcycle over another, when both are in the same type of service, is not generally due to any appreciable varia- tion in original quality and construction. Experience has proven that it is usually the direct result of the operator's knowledge of correct operating and maintenance methods and his diligence in applying this knowledge.
