The typical refurbishing procedure for all starters worked on at GravelyGarage is shown here using the 12V Delco Remy 1108311 starter as an example. Depending upon the starter model this procedure may not be exact but it is representative of the level of detail we give to all of our repairs.
|
Upon receipt of a starter it is completely disassembled. The armature is tested using a growler then tested with an ohm meter as well looking for any electrical anomolies. Once electrical testing of the armature is complete, it is put in a lathe and the commutator bars are trued. This keeps the brushes from bouncing against the commutator causing premature brush wear.
|
The field case and drive end housing is bead blasted then wire wheeled both inside and out. All bare metal is then prepped to remove any grease and oil at which point the inside of the field case is painted using red insulting paint and the exterior is painted black. After being painted black the drive end housing bushing is replaced.
|
The field coils are tested for the proper electrical characteristics and any broken leads and/or worn insulation are repaired as required. The pole shoes are wire wheeled and the threads are chased to remove any rust or debris.
|
At this point the starter is ready for reassembly. New pole shoe gaskets and pole shoe screws are used when reinstalling the field coils. The brushes, brush holders, brush springs, and pins are replaced. If needed a new terminal stud and insulators is installed. The brushes are then properly fitted to the freshly turned commutator. New thru-bolts are used to secure a new commutator end plate with new bushing and the drive end plate to the field case.
|
The unit is then bench tested and finally ready to ship!
