The 653143 plate is an OEM Continental aircraft engine hardware component used as a small retaining or spacing plate within engine assemblies. The “1/8 in dia” designation refers to its small-diameter interface feature, typically used in light-duty retention, spacing, or load distribution roles depending on engine model configuration.

In Continental piston engines, components of this type are commonly used in accessory housings, internal covers, or small fastener retention points where precise alignment and vibration resistance are required.

Key features include:

Genuine Continental OEM small retaining/spacing plate
Precision-machined steel or alloy construction (application dependent)
1/8 inch diameter interface feature for precise fitment
Used for load distribution or component retention in engine assemblies
Designed for high-vibration aircraft engine environments
Corrosion-resistant surface treatment depending on application spec
Maintains alignment of small engine subcomponents
Compatible with Continental piston engine assemblies (IPC-specific usage)
FAA-approved aircraft engine hardware component
Used in certified Continental engine assembly and overhaul procedures
