Starter 408 mk1

[David C]

The important distinction when looking for parts is that 407 to 410 engines are known as "Poly" engines due to the polyspherical combustion chamber. The other 318 Mopar option of similar but slightly later period is the LA 318. Some of the bottom end parts fit but very few from the top end of the engine.
Production of the Poly in the US ceased around 1965 but it continued in Canada for about 3 more years.

I think most of the 410s registered in 1968 and 1969 had engine numbers beginning CC318. One C is for Canadian and the other is the date code for 1967. The last few 410s had the suffix L for large sump. I don't know if they were different in any other way. I also can't remember if they began CC318. Unfortunately the BOC chassis list abbreviated the engine numbers.

I have found a starter motor with the same specification as the Australian one. Torqq 6203. It replaces 3-bolt with 2-bolt. The spigot is the correct diameter and the bolt spacing is correct.

However, there are two problems:
1. To run free of motor, it must be mounted upside down. Then the drainage ends up.
2. Pinion goes out 45 mm compared to 50 mm with original starter motor. It then has only half the engagement on the ring gear.

The flange is 7.5 mm thick. Expect to remove 2.5 mm which gives an engagement of 7.5 mm. Possibly I will make it in steel.

All the searches I've done in the US on my engine type only show remanufactured 3-bolt starters.

I don’t know if this will be of any help but many years ago when the original 410 starter motor gave up I got a geared replacement from the UK Jensen specialists Cropedy Bridge Motors who were just down the road from where we then lived. I bore it home in triumph on the back of my bike! It fitted perfectly and improved things enormously.

As you will know Jensens used the 7 litre Chrysler engine, from the USA

The point of this story is that it suggests that the Chrysler used exactly the same starter motor across a very wide range of engines and you probably don’t need to focus too hard on the exact engine type or where it was originally built
