348 Service on a car that sat?

I'd replace them. They're not expensive plus you're re-establishing the car's baseline in the process.

 

They probably don't go bad since I doubt that the tension load from the belt is that great. However, what-ifs can be unsettling, especially in regards to the bad batches of bearings a few years ago.

But hey, that's me. Others may say "why waste the money"?

 

I would inspect the bearings for play when I was replacing the belt. There should be absolutely ZERO play in the bearings. If there is any play they get pitched for a new set of Hill Engineering bearings.

 

When bearings are static for an expended time period they often have a chemical reaction between the lubrication the metal and possible moisture or other residue. Over time this reaction may cause minute divots between the ball and the race especially with belt tension. This can cause premature failure once you return your Ferrari to service.

As a matter of good conscience I would replace all bearings, tensioners and idlers, the cost is minor comparing a failure under stress and speed. As stated above, once done you will have established a new base line for future service intervals.

I would replace them. On top of what Howard said, The bearings still have static radial force which could leave small indentations while sitting in one spot. All rotating equipment needs to be, well, rotated every once in a while. The hard part is getting the engine out, so you might as well replace the relatively cheap bearings while everything is apart.

 

I am going apologize before I make this horrible analogy but pulling the engine and not replacing all the necessary parts that have anything to do with the belt is like quitting sexual intercourse before the orgasm.

 

Bad or not - the engine is out, and therefore the parts are accessible, and now you will know that there are quality bearings (Hill) in there, and next major you may not have to change them.

You will be "at square 1" an won't have to play guessing games with your engine.

 

Drive it and report back if anything goes wrong. Whattheheck, it's your car. Everything is ok til it isn't!
