Engine bay work continues today with the removal, cleaning, polishing and painting of the Mk1 Austin-Healey Bugeye Sprite. I've previously removed most of the engine accessories on the left side of the engine and the radiator. Having the radiator out of the way makes the removal process very easy.
The Mk 1 Austin-Healey Sprite has a cable driven tachometer powered by a "gearbox" on the end of the generator. Loosening the large brass nut allows the drive cable to easily slip off.
Disassembly of a Lucas generator is relatively simple. Two long thin bolts fasten the two end plates to the central generator body. Care was taken to photo how it all came apart, taking special note of wire connections and the condition of the brushes. All of the metal parts were dipped, dunked and polished. The body was sanded and given a coat of paint.
One of the interesting components of this model of generator is the self-lubricating rear bearing feature. The brass tube at the rear of the generator contains a spring loaded felt that is impregnated with high-temp grease. This should be serviced every 12,000 miles.
Here's the final product. As will be a continuing theme in my engine bay clean-up, I've elected not to paint the aluminum components. I've also not painted the pully and fan. I've seen this done both ways (painted / bare metal). I think this adds a bit of "bling" without adding additional chrome, etc. The clutch/brake pedal box and generator are now ready to be placed into short-term storage as I move on to removing the oil filter mount/adapter and the starter.
