Model 289700 Series Engines Replaced with Standard Service Engines
This manual provides guidance for replacing Model 289700 series engines with standard service engines. In most instances, the original type numbers can be directly replaced by a service type number without modifications. However, necessary changes to specific engine parts, such as crankshafts, reduction parts, or blower housings, are noted. It is crucial to ensure that any replacement engine's exhaust system duplicates the original system selected by the equipment manufacturer for safety and performance. Parts suitable for continued use should be transferred. Before undertaking any conversion, consult the data provided in the "REMOVE, ADD and NOTE" columns to verify the necessity of any listed changes for your specific application. Often, a standard service engine can serve as a workable replacement without requiring alterations like a special fuel tank or starter position.
If a crankshaft number is not listed in the "Original Engine" column, refer to the Illustrated Parts List for the correct service replacement crankshaft number.
