[Healeys] Starting a BJ8

I've found the best way to oil any "oilite" sintered bronze bush is to find an old vacuum cleaner spray gun. 
The "spray gun" is usually a glass jar, with a Bakelite top. Araldite the vent holes up, araldite a coin in the spray gun nozzle end, fill the glass jar half full with oil, drop in your bronze bush, & connect it to the wife's vacuum cleaner.
Watch the air rush out of the bearing sitting in the bottom of the glass jar. 
It's all done in a matter of minutes. 
Best

Clean the inside using e.g. a spray can of brake cleaner but be careful with some strong solvents in case they dissolve the shellac of the windings. Just clean up the commutator with 400 grade sandpaper, or better skim the commutator on a lathe, cut the insulator between the copper segments with a narrow (ground flat sides) hack saw blade to about 1/2mm below the surface if needed, inspect/clean/renew the brushes (when the commutator has been skimmed), oil the bronze bushes, clean the bendix thoroughly and lubricate with molybdenum/graphite powder rubbed in on the shaft and it should be fine for the next 25 years minimum.

If I am not mistaken there is a small hole in the back plate of the dynamo (and starter?) to lubricate the bronze bush now and again.
