Tom's 5GO Onan Restoration

1947 5GO Onan Restoration


I purchased this Onan generator a few years ago
for a retirement project.
I have about five months time into it now, working off and on.
The serial number de-codes it as a 1947 vintage.
It's powered by a Continental Y-91 four cylinder engine.
This is what it looked like when I purchased it.





The disassembly -


The back side of the panel. Radiator, grill, gas tank, etc. removed.



The generator before & during removal.





Head Removal - Lots of carbon!

Clean up, wire repair, & new toggle switches were required on the panel.
