Yesterday's candle light burned for my ex-NOS oil pump, the heart of my re (-re) build

After disassembling I found visible damage, done to it over its short, 172 Km life (I looked at the dark speedo of my engine-less Z earlier on today - call it 110 miles from now on).

But all was not bad. Due to the design of this engine, the glass that managed to clear the sump filter and was subsequently munched by the pump, was already ground by other equally expensive parts of the engine

so the pump was sort of spared extensive damage.

All measurements, carefully taken, were well better than tolerances which led me to believe the damage was superficial.
So decided to dress the two end plates, the only part worth touching. They were rubbed down by successive wet and dry emeries, beginning with 800, then 1000 and finally finishing with a mirror like 1200. No big deal, and they did improve markedly.

In the end everything was cleaned with copious amounts of brake cleaner and readied to be assembled

All was put back together using clean engine oil, that that was that. Sorted

It is amazing how much dirt brake cleaner will shift from visibly spotless parts - I love the stuff.
BTW I am trying to use my humble Panasonic LX-3 camera as a microscope ... here are some shots, all relating to the pump which you might find interesting:
