I am going to look at a used paxton sn92 today, should this unit come with a fmu? how can i tell if it needs a rebuild? I dont think the seller has a fmu. Should it have an oil cooler?
Should have a FMU. It should be hard to spin but yet be really smooth. Oil Cooler was a extra back in the day and you will be fine without if you stay under 6psi
