No, at least not on a '93. It can get pretty torn up during removal and just don't scratch any critical crankshaft surfaces.
Check out a number of the Z32/300ZX VG30DE and VG30DETT timing belt removal and installation related write-ups (complete with color photos) that are out there.
It still makes me a bit nervous thinking about removing and installing all five front oil seals, but about 10K miles later all still seems to be good. I even very carefully used small amounts of RTV around the new seal ODs, while also oiling the IDs.
Do the four camshaft seals first, practicing up for the crankshaft seal that is more difficult, different in a number of ways and more nerve-wracking. At least they should all be the same seal/part.
