Crankshaft Seal Oil Leak, Vetus Coupling Bushings Replace & Gearbox Oil Cooler Fix on Volvo Penta

All of our sailboat repair and maintenance blogs are now hosted on our dedicated maintenance channel, MOTHERSHIP MAINTENANCE Check it out here: https://www.youtube.com/c/mothershipmaintenance

In this maintenance blog, I engage the help of a professional mechanic to replace a crankshaft seal and the Vetus coupling bushings.

For the last few years we’ve had a slow but persistent leak from the flywheel housing which had been diagnosed as a worn crankshaft oil seal. However to get to THIS piece involved removing the prop shaft generator, gearbox, starter motor and flywheel and to get to THOSE, we had to disengage the vetus coupling and prop shaft, dissemble the engine cradle and move the entire engine back on its mounts. Along the way we replaced the the vetus coupling bushings and also discovered a very corroded gear box oil cooler which needed a clean up and new cover plate.

You can see why I called in a professional on this particular job!

On the recommendation of fellow Amel owners we dropped in to Yacht Concept in Porto Christo, Mallorca owned by Peter Kukloc and for a few days his mechanic, Torsten came onboard and kindly let me film him work and bombard him with lots of questions. He was very patient!

The marinas in the Balearics are extremely expensive so we wanted to spend as little time as possible on dock. However, we had to wait for parts and the job eventually ran over the weekend so we were there for 5 nights in total. Even though Porto Christo is one of the cheaper marinas (basically a municipality owned town quay) it added a further €355 to the cost of €2230 for the entire job. Thanks to one of our patrons who helped towards the cost of this by the way.

Incidentally we also had the belts, pulleys freshwater pump replaced at the same time but as there’s so much to see in this video, I’ve put it in a separate maintenance blog!

Tip – source your own spares BEFORE the work starts and begin the job early in the week to prevent the repairs running over the weekend and incurring extra marina costs.

Although these videos show maintenance work on a TMD22 marine diesel engine, many components and assembly techniques are similar across the Volvo Penta range, including: MD22L; MD22P; MD22L-B; MD22P-B; TMD22-B; TMD22P-C; TAMD22P-B; HS25A; HS25A-B; 120S-E; MS2A-E; MS2L-E; MS2B-L; TMD22B

In response, we have enabled comments for these videos on our Facebook page and Patreon page and begun a monthly blogspot called: ‘FROM THE COCKPIT’ where we respond to comments questions and issues relating to travel and sailing with kids.. and live-aboard life in general.
