🔧 Product Description

Genuine Volvo Penta splined socket in the small size, used for turning the vertical shaft in the lower unit. It is an overhaul-class special tool weighing 0.229 kg. Two other tools carry the same splined socket name and are not alternatives to it: 3850618 is listed as a holding fixture used with 3862847, and 884830 is listed for turning the vertical shaft without the lower-unit qualification.
