PREFACE This parts catalog comprehensively lists all the structural parts for all pieces of equipment and thus may be regarded as a master catalog. Included are a description of parts that have been altered to adapt to improvements in equipment, and their suitabillty for designated pieces of equipment and interchangeability, The information is provided for both parts sales and servicing use. your opinions and comments on errors in this catalog will be greatefully received. They will be included in subsequent revised versions. Composition of the master catalog The master catalog consists of the front cover(binder), inside title page, notice of revisions, preface, index, table of contents, main text, index of parts numbers in sequential order, and colophon.

A change has been made from the part shown at the top Old part- to the part shown below. The new part is New part interchangeable with the old. old A change has been made from the part shown at the top x to the part shown below. The new part is not New interchangeable with the old. Interchangeability of parts under certain conditions (interchangeability of multiple parts) is not described here, but is given in the notes section beneath the parts sections. (6) Suitability for Different Machinery The applicable equipment numbers for whith the part is used are given. (Example) 1151 -. ............... May be used for all equipment number 1151 and equipment subsequently numbered. 1152 - 115262 ......... Parts used in equipment numbered 1152 through 115262. NOTE: The equipment numbers for whith parts are stated as being suitable are based on plant shipments. Thus, information on modifications that have been made at destination sites based on local service updates is not covered. Please refer to related informational updates to ensure the appropriate parts are ordered.
