TO FIND

THE CORRECT NUMBER OF THE PART YOU NEED:

FOLLOW THE INSTRUCTIONS BELOW

A. Refer to Engine Model, Type and Code Number that is stamped on the blower housing of engine.

Engine type numbers such as 0123 01 are listed only as 0123 in most instances. The two digits (01

or 02, etc.) to the right of the space may be required for more accurate parts identification in some

instances. Select the Illustrated Parts List covering the correct Model Series and Type Number.

B. Refer to the Illustrations and compare the original part with Illustration. The number next to the

illustration is the Reference Number. Assemblies include all parts shown in frames. All parts shown

in assembly frames having individual reference numbers can be purchased separately.

C. After the Reference Number has been identified, refer to the Numerical text, where Reference and

Primary Part Number are listed. THE PRIMARY PART IS USED ON ALL TYPE NUMBERS

EXCEPT THOSE TYPE NUMBERS UNDER “NOTE.”

D. If a “Note” appears below the Primary Part Number, it means that this part differs from the Primary

Part for certain types. If your Type number is listed under “Note,” order the part referred to at the

“Note.”

E. If your Engine Type Number does not appear after any part number listed under “Note,” use the

Primary Part Number.

F. For Engine Type Numbers not covered by this book, check other Parts Lists having the same

engine model or contact your source of supply.
