What this video covers
Replacing the rubber bellows on a Volvo Penta MD2030 saildrive requires a complete assembly of the gearbox and drive leg, ideally performed while the engine is removed from the boat.0:07 The process begins by cleaning all mating surfaces with isopropyl alcohol.4:25 A paper gasket, coated in waterproof grease, is placed between the gearbox and the saildrive leg, ensuring no grease contacts the rubber bellows.6:00 The assembly is secured with bolts torqued in two stages: an initial pass at 10 Nm followed by a final torque of 25 Nm. Locking wire is then threaded through the bolt heads to prevent loosening.7:07
To address a worn propeller shaft causing water ingress, a Speedy Sleeve (part number 99125) is installed over the shaft to provide a fresh sealing surface.10:12 The shaft is inserted into the drive, and the bearing housing is sealed with gasket compound and bolted into place using a cross-pattern to ensure even seating.12:19 The manufacturer recommends replacing the rubber bellows every seven years to maintain watertight integrity.0:58
