Lycoming Engine Cylinder Application Guide

Air Power's Cylinder Application Guide - Please always consult the manufacturers most current Illustrated Parts Catalog or reference Lycoming Service Instruction 1037 for detailed information


Engine models that have serial number suffix “A” or “E” are built with crankcase configurations for wide
cylinder base mounting flanges, and consequently must be assembled with “wide deck” cylinders.

Engines with no serial number suffix require “narrow deck” cylinders. Refer to the latest revision of
Lycoming Service Letter 220 for additional information on differences between Narrow Deck and Wide
Deck Engines.
