I have decided to replace the Starter Motor and Dynamo on my 1955 TR engined +4 with a High Torque Starter and Alternator. I went to a well known supplier in the UK for TR parts and bought a motor and alternator apparently suited to my particular Engine number. The starter motor supplied does not fit. I have checked dimensions and its close enough to be a simple tolerance issue however can anybody provide details (make/model) of a high torque motor that they have successfully installed. The motor that came off the car is a Lucas M418G which matches the info I have found for original fitment on a Morgan TR engined +4. Does anybody know if the same was fitted to an actual Triumph TR2 - 4? It would be strange for a Morgan TR engine to have a different mount to a triumph TR engine.

On the alternator I have asked the suppliers advice on the bits I needed for the conversion. I bought alternator, wiring lead, pulley, and mounting kit. After ordering I figured out that I probably needed to do a wide to narrow fanbelt conversion so I also ordered the kit for that. Has anybody done this conversion and can offer advice? One thing is the alternator came without a fan on the front. Looking back it seems to be an extra which my "expert" supplier failed to mention I needed. Is it needed? All alternators I see seem to have one. Any advice on how I would go about getting existing Water pump and crank pulleys off the car?

Thanks in anticipation

Andy

For my 1954 +4, TR2, standard manifold and exhaust, I have installed a Powerlite RAC103 starter motor from AES (Auto Electric Supplies). Perfect fit and the best mod I have made to the car. If I remember correctly there are two pinion nose lengths and it is important to get the right one.

Thanks folks for your input.
Turns out I have the wrong starter motor. Its the correct motor for my engine number but it turns out I do not have the expected ring gear on my flywheel. I will need to try again. I suppose I should have predicted this as I know its not the original engine but its probably the original flywheel.
