Hey guys,
The end of last year my oil pump drive pulley snapped off, today I finished opening up my 7m to check whats going on, nothing seems seized, I can turn the engine over just fine by hand, I can also turn the oil pump shaft without a problem. If anyone has had a similar problem or knows what happened it would be great to find out, my teacher took a look and isn't sure either. I know that Beech performance has their retention plate that they sell but my plate looks fine and fully intact, so I don't see what went wrong.
This is the pulley hanging where it should be, you can see its broken and quite a bit of metal was sheered away
This is the inner section of the pulley
