Are the plain bushes porous bronze as later Lucas? Not supposed to be reamed but I have encountered non standard undersize. Are/were these supplied undersize?
It always amazes how little wear occurs with these bearings on a soft shaft; on other cars often little lubrication. And not a problem with Sevens but on other makes seldom any advice to reapack the ball race. On 60 year and older cars with unsealed bearings these often very dry.
The key may not pass through the bush... as I once discovered when not concentrating.
On DEL dynamos it is important not to restrain the small ball race.
