Generator Pulleys and Alternator conversions

[Michael Echemann]

Scott:
As I understand it Amphicar did have a optional metal pulley available. Not
to make is sound like you could check it off on any order sheet with the
larger engine, dual carbs or A/C but most likely via replacements through
the parts dept.

Whilst rummaging through the pile a parts attendant to my once and
future Amphicar I came across a cast metal pulley (chromed too!) that is an
exact duplicate of the Bakelite one on the car and the remains of the
Bakelite one on the spare generator (wonder how it got all broken?). Would
this be a MB or Porsche part? Given the life expectancy of the original
plastic ones I don't want to get rid of this one but it appears that there
are metal equivalents out there!
At first I had to laugh at the question of whether to switch to a GM
alt. or Triumph alt. A frequently reoccurring topic on the Triumph list is
the procedure of switching from a Triumph alt. to a GM one. But, if a
direct swap is easily available that might be a better way to go.

Happy swimming

The plastic pulley has always been a puzzle - they were never fitted to the
engine when in a Triumph Herald/Spitfire yet all other parts, the generator
itself, the pulleys and the belt were the same as in the Triumph cars.

The best explanation is that the plastic pulley was specified by Amphicar to
provide more airflow over the generator and so better cooling - they do run
hot - and Amphicar were very concerned - almost paranoid - about engine
cooling, they had lots of problems with the prototypes, that's also why they
fitted an oil cooler to the engine, if you measure the oil temperature it
isn't really needed (except maybe in 90 degree heat)

The metal pulley is most likely the ordinary Triumph part.
