My late '64 Herald 1200 convertible has a Dolomite 1300 engine. For some time now the starter has 'meshed' occasionally - once the ominous 'click' has happened I have just put the gearlever into 4th & either pushed the car a foot or so forward or backwards so that the starter would engage......invariably she would start instantly.
Needless to say the situation has got worse with the occasional severe locking up which no amount of rocking the car will free. A spanner on the starter 'pinion' has saved the day on a couple of occasions...
My question is, is it better to look for a replacement flywheel - or would it be better to get some new ring gear for the existing flywheel? I am presuming the gearbox is original Herald so what flywheel should be sought if it needs to be replaced?
Scimher, What makes you think that the ring gear is at fault?
Far more likely is the starter motor pinion throw-in mechanism. I think the original had a Bendix gear, that uses the inertia of the pinion on a screw thread to throw the pinion into gear with the ring. The Bendix notoriously becomes fouled with clutch wear debris and oil. Remove the starter, clean the Bendix gear and lubricate with graphite powder - never oil or grease.
More modern starters, and the Hi-Torque versions retro-fitted to Triumphs, had a 'pre-engaged' pinion, pushed into place by a solenoid, identified as a second cylinder on top of the starter. They are nore difficult to service.

Thanks very much for your prompt response, John - the starter motor was replaced 6 or 7yrs. ago.....The only thing that I have to go on was that I was told that the fault was due to some broken teeth on the flyheel, a few years ago. The problem has got considerably worse.
Worth removing the starter and doing what John suggests first off as it's free and won't take very long. Check the condition of the starter teeth - if they are mangled then that won't be helping.
While the starter is out, take a look at the ring gear through the starter hole. Wear will be noticeable at two diametrically opposed points (or 3 points @ 120º on a 6 cyl) because the engine usually comes to rest near the top of a compression stroke. The wear will be on the back side. If the teeth have almost gone then you'll need a new ring gear or a better flywheel assembly. If they are just ragged and burred then a tidy-up with a file in situ will help.
