An adapter is disclosed for use in mounting an ancillary unit in an engine block which has at one end a lateral flange () formed with an aperture for mounting of the ancillary unit. The adapter comprises a casing () for mounting on the end face of the engine to overlie theaperture, which casing is provided with an O-ring () for effecting a seal between the casing () and the aperture in the lateral flange of the engine. The casing has a larger diameter portion separated by a shoulder () from a portion of reduced diameter, a retaining sleeve () axially slidable over the reduced diameter portion of the casing () and a O-ring () held captive between the axial end of the retaining sleeve () and the shoulder ().

Seal accessibility device

An engine is described having a hole for a dipstick which is closed by a cap from which the dipstick depends. The engine body is formed with an overhanging lip adjacent the mouth of the hole, and the cap comprises a spigot rotatably received in the mouth of the hole and a flange extending radially outwards from the spigot to cover the mouth of the hole. The flange is non-circular so that by rotation of the cap relative to the hole, a radially projecting portion of the edge of the flange may be selectively engaged beneath the overhanging lip to prevent axial displacement of the cap and the dipstick relative to the engine body.

Internal combustion engine

An ancillary unit drive adapter is disclosed for use in an engine block which has at one end a lateral flange formed with an aperture for mounting of the ancillary unit. The drive adapter comprises a casing () for mounting on the end face of the engine to overlie the aperture. A shaft () journalled in the casing, has a formation () at one end for coupling to the input shaft of the ancillary unit and a cog () solid with its opposite end for meshing with an engine driven gear. Faces () on the opposite sides of the cog () serve in use as bearing surfaces to withstand axial forces acting in both directions on the drive shaft ().
