Introduction
This parts catalog applies to the Cummins Power Generation standard generator model GGMA, GGMB, and GGMC
as listed in the Generator Set Data Table. Parts are arranged in groups of related items and each illustrated part is
identified by a reference number corresponding with the same reference number in the parts list. Parts illustrations
are typical. Throughout this catalog left and right sides are determined by facing the engine end (front) of the set.
Engine parts that have been modified or added by Cummins Power Generation are identified in this catalog. All other
engine replacement parts must be ordered from the engine manufacturer by referring to the engine manufacturers
nameplate and supplying all available information. Contact your nearest engine parts distributor for assistance in or-
dering replacement parts.
