I have a 1275 A+ freshly built engine, I assumed it used a pre-engaged starter but before it went off for machining it had an inertia on it. I counted the teeth today on the flywheel and there are 107. Is that pre engaged or inertia?


Thanks

107 teeth on the ring gear means the old fashioned intertia starter....

A + engine always had pre-engaged starter - but it depends on the ring gear on the flywheel. The inertia starter enters from behind (!) - the pre-engaged does so from the front - and the ring gears are angled differently to allow this. They can be swapped about. So - you need to look at the ring gear to see which starter it will accept.

When the A+ first came out it had a pre verto clutch and inertia starter, but I think all vertos had pre engaged starters. Bmcecosse's advice about teeth profiles is the most useful indicator.

Agreed - all A+'s were not Pre-engaged...

And to confuse it even more: my A+ (998) had a verto clutch with inertia starter

Wow - sure it's not mix and match in later years ? I'm pretty sure part of the A+ upgrade was to verto clutch and pr-engaged starter. But - perhaps there were some in-between cars! Of course - some have used an inertia starter on a verto flywheel - either turn the ring gear - or put up with the badly meshing teeth noise!

There certainly are some strange things that came out of rover.

I had one of the few A+ 1098's - and that was running inertia start gear...

Badly meshing starter is one of my favorite 'horrible' noises

[Asphalt]

I think the pre-engaged starter was introduced by 1987?

On my SPI engine the inertia starter just locked up solid
What a bugger to remove it then...

[CraigyBoy]

so am i right in saying a 107 tooth ring gear is for an Inertia starter?
