Dynamo & Starter

The electrics were badly corroded, although appear to be complete

February 2004:

The dynamo commutator and brushes needed no more than a wipe-over and the brushes easing in their mountings

the dynamo pulley bearing has a simple greaser - saves taking the dynamo apart every time!

the original dynamo top mounting was fatigued and cracked . . . . . . . . a common fault . . . .

. . . . so a new one was purchased from Available Austins. The new fan belt and dynamo was then mounted back in its cradle.

The original fan had been repaired and rebalanced but it really was past it.  If it flew apart it would demolish the radiator - so a new one was purchased - again, Available Austins.

April 2004:

The Bendix drive of the Starter Motor appears to be OK - this version has no return spring, but has two metal fingers to hold the pinion in the disengaged position.

When dismantled, the Starter Motor endplate was very oily and grubby; two of the brush springs were broken

The starter brushes look good for a few starts yet - as subsequently proven when it wouldn't start immediately after the engine rebuild.

A broken brush spring - fortunately the spare starter that came with the car yielded two good spares.

the solenoid mounted on top of the starter has no economy coil and gets hot very quickly - so keep starting bursts short

February 2006:

the old solenoid got very hot and didn't always work - a sure sign of shorted turns

- so it was replaced by a modern version. Although it looks different, it fitted exactly

December 2007:

this new solenoid failed - as it is a new item of modern design this is not good! Auto-Electric Supplies provided the replacement which fitted straight on.  Pictures look the same as above so not repeated!
