Gasket, Cylinder Base Shim 87134109-101

Technical Description

Precision aerospace steel cylinder base spacer shim gasket engineered to establish precise structural alignment and stack tolerances on aviation piston engines. Manufactured from premium, high-strength spring steel to withstand continuous mechanical compression forces and severe engine temperature cycles. Designed with a custom four-lug annular configuration to match engine cylinder base studs perfectly, preventing structural shift. Serves as a vital static spacing barrier that optimizes combustion cylinder deck height while eliminating oil migration pathways along the lower crankcase split-line.
