I bought a rebuild kit, piston and bearings and rings. I did a trick hone on a 30hr compressor and soaked bearings for a month prior to install. Been great. If unit has a bunch of hours on it I would buy new. But disassembly and inspection is quite easy.

In my experience the crank journal had failed without noticeable failure of the rod end bearing, which I thought was very strange. One roller element had slight surface putting but they rolled very smoothly. The crank journal had quite a bit of material missing on one section. It was enough to cause noticeable knocking but it never went all the way catastrophically.

Not don but no prescribed time to replace, some never fail, some last no time, mine did not need it, I just did it to improve hone quality, seems to have worked well. Kit is available from pro marine, if in fact they have any, comes with all O rings. Not something I would recommend with out experience rebuilding stuff. Crank is usually the failure point. Don is right, if it does fail it could cause much more expense. Injector cleaning, rail cleaning etc. buying a new does not guarantee that it won’t fail either. You can replace o rings and inspect if u suspect a problem as long as u have a Manuel to go by, torque wrench and a bit of time to clean and allow bearings to soak…

There is no designated hours or time interval for compressor replacement. I do a basic check of the compressor when I'm servicing an engine (belt off, check bearings/shaft for play, unusual knocks or bearing noise, etc.
Lubricating the compressor when the engine will be sitting for more than a month or so MAY improve the lifespan (corrosion from moisture in the air condenses in a compressor, which can cause corrosion). This is noted in the FAQ Section, Recommended Annual Maintenance..... Post.
