When do you rebuild a Marzocchi gear and when do you just get a new one?

Since I am into hopping, I would just replace the whole thing, I might replace the seal if it's leaks.

But if I were to rebuild them, I'd look for a loss of performance. If I bought them used, I'd look to see if there was any scoring.

If I was to get real fancy, I might hook it up and check the vacuum (inlet side) and check for leak down.  And of course pressure and flow.

But I am unsure what is meant by rebuild?  If the gears are messed up, I'd toss it, or save it in the parts bin.

Seems like I would replace the gear head.  It sounds like there might be a ton of scoring inside. If you take it apart you may see what I mean along the gear housing.

Take note on how you take it apart. mark everyhting or take pics,
