Triumph TR6 Starter Motor
TR6 PI cars were always fitted
with a pre-engaged type Lucas starter motor of either the M418G or 2M100
model type. Due to further improvement by Lucas, the later type 2M100
model starter is supplied for all replacement purposes. The M418G
starter is identified by the Lucas part number 25626 stamped on the main
casing. The 2M100 model is identified by the part number 25647 stamped
on the main casing.
M418G starter motors have the electrical carbon brushes bearing on the
sides of the armature's commutator in a radial manner. The carbon
brushes of the 2M100 bear against an end facing commutator in an axial
manner. The components of the two design starters are not
interchangeable, the complete starter motor assemblies are.
The starter motors listed here are suitable replacements for both of the
original types however, if you intend to carry out repairs to your own
starter motor, you must establish which model starter is fitted. To do
this you must obtain the model type and part number from the starter
motor main casing and refer to the relevent section of the website.
