Schematic and parts for a Speedaire model 5Z044B

I bought a Speedaire model 5Z044B recently. It needs a lot of work and parts.


I went to Grainger and tried to get a schematic but was told that it is obsolete and they cannot help. I believe that it is circa 1989.

It is a 5hp direct drive 3 phase. I am going to have to change it to a single phase motor. The original 5hp motor turns 1740 rpm. Most of the single phase 5 hp compressor motors that I see turn around 3800 rpm. Would that be a problem? Overheating maybe?

Mostly I need a schematic. Anybody know where I can get one?
