The 2332, made 1947 to 1949, was well illustrated in the Lionel Service Manual. Olsen’s online library has a copy of it here:

The only thing tricky about assembling the 2332 is that sometimes there is a brass washer between the motor mounting post cast into the shell and the motor mounting bracket attached to the truck. If this washer was there and has been lost, the two 6 wheel trucks that support the shell may not share the weight of the loco. This will result in derailments. If you have derailment problems, try adding a washer.
