STARTER MOTOR

[CDUNN]

The starter motor on my 1968 S2 FHC Manual has finally failed. I don't think I can complain as it looks as though it has done decades of service. I can see that it is a Pre-Indexed M45G starter and the parts book indicates that C27178 was the original fitment. A while ago I bought a refurbished M45G starter as a spare and intend to use this to replace the failed one. On closer inspection, I suspect that the refurbished starter is the later M45G type which was slightly smaller than C27178 together with some other slight variances. The markings on the refurbished starter are Lucas 3M100 25684E 54247036 (DOM Week 15 1978) and I think this was C22256. My question is whether or not my refurbished starter can be used to replace the failed one. When I get the failed starter out of the car I will see what the body markings are. Any thoughts?

If you check out SNG Barratt's website, they recommend a variant of the C22256 part number for E-types, which appears to be slimmer than C27178. Hence, you may already have the correct starter as your spare. If you remain unsure, drop Ken Jenkins an email. I'm sure he will be able to give you chapter and verse on the subject. Mike.

Thanks. I am confident that the spare starter will fit; it has a 29mm O/D pinion gear and the gear has 9 teeth. It is difficult to say categorically whether the spare starter is slimmer than the existing one or not but it does look to be so. The wiring between the solenoid and the starter is different. On the existing starter, a heavy cable connects one terminal of the starter to the solenoid. On the spare starter, this is a solid link which may be a consequence of the remanufacturing using a more design of solenoid. The existing starter is now free and the final job is to manoeuvre it out of the car. So far, it has not been as bad as I was expecting (given some comments I've read about the job) and I think the most awkward job was to remove the two inner set screws securing the reserve vacuum tank. It is a job that needs patience and ingenuity. And small hands.
