crankshaft journal wear

Hi

the rough metal below the smooth surface of one of my engine crankshaft journals is starting to show.

can it still be used?

can it be repaired? or does it your better to find another in better condition?

Can you provide a picture of the journal(s) and the bearing shells that came off it? It sounds like there was some debris embedded in the shell that has damaged the journal - there should normally be negligible wear if the oil and filter were serviced regularly.

If there is damage, it may be possible to have the journals remachined undersized, with suitably sized bearings.

What do you think?

It looks like it has some surface rust, but it should clean up with a grind to the next undersize - it looks a bit too much for a 'polish'

thank you Gord for your answer, so if I understand correctly this requires special work done by a specialist?

On my island there is no machine shop, so I would have to change it.

Since most of what I know about Martinique and the Antilles is derived from the film "To Have and Have Not", and the TV series "Death in Paradise", I thought some checking would be in order.

The populations of that region is a bit higher than one might imagine, and when you consider the need for 'making do' due to having to ship in most parts, I would expect at least one decent engine machinist in the area. However, a search didn't really come up with anything. I expect there will be issues with different countries 'administrations' and possible customs and other red tape, but hopefully some helpful suggestions.

I applied a little lateral logic - there are a LOT of sailing and motor vessels in that part of the world, and they will need servicing and repair, as will vehicles sold by dealers, so there must be some sort of support services around them, so if you check out some of these local to you, they may be able to direct you to a good machinist in your area - https://www.sailboat-cruising.com/marine-diesel-mechanic-caribbean.html

I don't know about specifics for your island's car and truck dealers, but I would suggest inquiring where they get their repair work done - for example, https://www.antillespower.com/about-us/ or https://motorworldgroupsxm.com/

thanks Gordon I will deepen my research

A few other possible avenues to chase down - marinas, not sure what you'd call them but 'Port Master' office you can contact. Airports, most island areas have at least small aircraft flight services and those aircraft require maintenance. Possibly motorsport clubs on nearby islands - don't just think land vehicles as there may be a thriving power-boat culture there. If you're lucky and find something, you may be able to send your crank off with other people's parts and possible reduce shipping costs.

Sorry I can't be of more help, but hopefully that's opened up some more possible options for you for this, and other, machine work.
