摘要： A engine and cover assembly therefore and method for snapping attachment of the cover to the engine without use of threaded fasteners includes a cover, a clip, and an elastomeric dampener. The clip is arranged for snapping engagement to a flange of the engine to secure the cover to the engine. The clip has a first portion extending from the cover and a rigid second portion for snapping engagement with the engine flange. The elastomeric dampener is spaced from the second portion of the clip to provide direct engagement of the second portion of the clip with the flange of the engine.

摘要： A shaft seal for forming a dynamic seal along an axially extending annular running surface and method of installation thereof is provided. The shaft seal has a mounting portion configured to be connected to a stationary housing and a seal lip having an annular sealing surface extending between an oil side end and an air side end of the seal lip. The sealing surface is configured to extend axially along a shaft running surface. An annular bridge portion connects the seal lip to the mounting portion. A plurality of webs extend generally radially between the bridge portion and the mounting portion to prevent the seal lip from being inadvertently unfolded during installation or while in use. An annulus can be used to install the shaft seal into a housing and about a shaft without the need for secondary operations.

摘要： An annular wear sleeve for a shaft seal is fabricated of an elastically deformable metal material and includes an annular body portion and an end flange portion. The sleeve is slightly oversized relative to the shaft on which it is installed to provide a low force slip-fit installation on the shaft. Once installed, the end flange is elastically deformed, imparting a radially inward bending force on the body portion causing the inner surface of the wear sleeve to constrict about and engage the outer surface of the shaft, providing intimate metal-to-metal contact therebetween to dissipate heat from the seal member and to secure the wear sleeve against rotation on the shaft in service. Releasing the deformation force on the end flange enables the wear sleeve to recover its elastic deformation, causing the wear sleeve to release the constricting engagement with the shaft enabling it to be dismounted from the shaft with low force in the same manner as was required for installation.
