CHAPTER 1 INTRODUCTION TM 9-2910-226-34 Section I. 1-1. Scope. This manual contains instructions for direct and general support maintenance of the Metering and Distributing Fuel Injection Pump Assembly (fig. 1-1 through 1-12). It contains descriptions of, and procedures for troubleshooting, disassembly, inspection, repair, and assembly. The pumps are used on multifuel engines as listed below. To differentiate between pump models, each pump model has been assigned a code letter. Paragraphs and illustrations which apply to different models will have the defining code letter as part of their title (i. e. Code A pump). LDS-465-1 and LDS-427-2 engines were equipped with two or more different pumps that were installed during product ion of the engines. The LDS-465-1 pumps will be defined as Early Code F and Late Code F pumps. The LDS-427-2 engines were equipped with three different pumps and these pumps will be defined as Early Code G, Late Code G, GENERAL and Rebuild Code G pumps. Where illustrations apply to all pumps no differentiation will be made in the title or the word “typical” will be inserted. Although some engines used the same pump, the pumps have been assigned different code letters to retain engine identity.
