Product Reassembly
| 1 - Very easy, highly intuitive, trivial. Part is reassembled easily and quickly. |
| 2 - Somewhat easy, intuitive, some thinking. Minor difficulties encountered. (i.e. many bolts, time consuming but still easy.) |
| 3 - Average difficulty, awkward part location. (i.e. parts were hard to get to or required special tools like a ratchet extension) |
| 4 - Difficult, requires large force, not intuitive. (i.e. required planning in order to reassemble) |
| 5 - Very difficult, requires maximum planning, parts were previously broken. |
The following table describes the process for reassembling the generator. Significant notations include a sequential numbering of steps involved, the tool(s) used in each step, challenges presented to us and how they were overcome, differences from the dis-assembly process as well as the relative difficulty of each step.

Our reassembly process differed from the original factory assembly in multiple ways. For example we were unable to press the flywheel and commutator back onto the crank shaft without breaking the flywheel in three places. We assume the commutator was originally expanded using a high temperature source to heat the metal component so it would fit snugly over the crankshaft upon cooling. We were also forced to remove the bearing at the top of the commutator on which the brushes contacted the slip rings, in order to be able to place the stator back on the generator over the commutator. Another issue we encountered was the use of excessive torque on some of the bolts when we were reassembling as this led to shearing or general damage to the bolts. The manufacturer would have had some sort of pre-programmed set up to tighten the bolts to a specified torque. Another difference we encountered was the damage to the threads of the crankshaft onto which the armature nut was tightened had to be sawed off of the unhurt threads in order for the bolt to have a chance at fitting on. The manufacturer would not have dealt with the damage to the threads because there wouldn't have been any in the original assembly.
