Spring Washer 102144

Spring Washer(Part No.: 102144)

This spring washer is a critical component in certain gas engine models, primarily used in connection with cylinder head bolts or other high-stress fasteners.

Function & Purpose:

Its core function is to maintain a constant and adequate clamping force in the bolted joint. It compensates for slight settling, thermal expansion/contraction, and vibration inherent in engine operation. This prevents the fastener from loosening, ensuring a tight seal (e.g., for the cylinder head gasket) and maintaining proper pressure distribution, which is vital for engine performance, safety, and longevity.

Method of Use & Key Features:

Installation: It is placed under the nut or bolt head, with its bowed (curved) side facing the bearing surface. As the fastener is torqued to the manufacturer's precise specification, the washer flattens.

Action: The flattened washer acts as a spring, continuously applying a counter-force against loosening. It helps maintain the designed preload on the fastener even under dynamic engine conditions.

Key Feature: This part is specifically designed to withstand the high temperatures and dynamic loads within a engine. Using the correct OEM part (102144) is essential for proper material compatibility and performance.

In summary, the Spring Washer 102144 is a vital sealing aid that ensures joint integrity by providing sustained tension, thereby safeguarding the engine against leaks and potential damage from fastener fatigue.
