ABSTRACT:
A method of facilitating assembly of hubs, particularly hubs intended for boat engines and being of the kind comprising an outer sleeve, e.g. a propeller sleeve, a hub sleeve mounted coaxially in said outer sleeve, and a rubber bushing between the inner and outer sleeves. In accordance with the invention, the bushing is mounted on the hub sleeve in a non-vulcanized condition, whereafter the sleeve and rubber bushing unit is positioned in the outer sleeve, whereafter vulcanization is carried out. In addition to facilitating correct positioning of bushing and hub sleeve in the outer sleeve the invention provides the advantages of making specialty tools superfluous for mounting of the hub, making possible to reduce the thickness of the outer sleeve as heavy stresses are no longer exerted on said sleeve during mounting, and making storage easier.
