These images show a British Phantom I starter after and before being overhauled and tested. It required new bearings, brushes, and brush insulating material. We also machined the commutator and checked the armature and field coils for electrical resistance properties.                            



This 20/25 engine has been completely overhauled.  The pictures below show the engine while being dismantled. All the internals have been thoroughly cleaned,      clearances reset to proper limits, and the water jacket has been pressure tested. Also the finishes have been renewed for a proper appearance and corrosion resistance.                                                                                                                                                                                           






To the left are views of a 20/25 rear shock absorber before (lower) and during (above) overhaul. Once the unit has been dismantled, cleaned, and the clearances checked, it will be reassembled, with new gaskets, seals, and checked for proper resistance poundage to provide a smooth and comfortable ride.
