So i'm in the local trattoria, and the owner says the main exhaust fan is making noise.
Probably needs some oil, so he pulls out an old oil can with the flex spout. It is a 1-story, flat roof, and he keeps a ladder handy,
so i climb up. There is only one, incorrectly sized bolt holding the cover, which is removed without a fuss.
I'm greeted with a couple of grease fittings, a belt that looks to be in the 20yo+ range, and significantly misaligned pulley.

Grab my grease gun and decide whatever is in there will be fine. The zerk fittings took the lube, so that was good, and it did quiet down a bit.
Peeped the belt number, then $10 and two days later, I'm back on the roof. Needed the hammer to remove the pulley from the fan shaft (left my puller at home, duh.)
The last person put the key in the wrong way, which is why they couldn't get it to align, even using a BFH.
Ah, exhaust fan bliss.
Yes the key is sticking out, it was bent from the previous attempt. Plenty of length remaining to secure it with the set screw.

Everything in a restaurant is disgusting. I fixed the slicer a couple weeks back.
Spent more time cleaning it than actually repairing it.
