STARTER MOTOR

CAR-IDENTIFICATION LATE SPRITE & MIDGET (1967-1979)

A model year does not necessarily coincide with the year in which the car was built. For example, it may be seen from the following chart that while a car built in January 1972 is indeed a 1972 model year car, another one built in August of that year is a 1973 model year car. There are several different reasons for this. One reason is that it is easier to bring in changes in a model's specification when production has been halted already for a holiday shut down. Another reason is that motor shows usually took place in the Autumn and Winter, displaying the following year's new or updated models. Detailed here are the Sprite and Midget model years relevant to our categories.

Sprites and Midgets were all fitted with Lucas starter motors. Lucas developed the starter throughout the production life of the cars; the net result was two starter motors of clearly different construction which were, in fact, interchangeable. They may be identified by the following: Lucas Type M35G (original MG part no. 13H559): Stamped with Lucas no. 25079, plus suffix between A and H. Lucas Type M35J (original MG part no. 13H5798): Stamped with Lucas no. 25149. The factory has now replaced the early design (which had radial brushes contacting a ‘side’ commutator) by an all-variants-encompassing starter motor of the later design (with axial brushes contacting a ‘face’ commutator). So if you want to order parts for your existing starter, these differences are important. If, on the other hand, you want to buy a new part, these differences do not matter.
