Alternator Update

Colin Satchells Alloy Alternator Pulley wheels turned up a while back, but I’ve been too busy to post up about them.

Shiny!

Few extra weights:

Steel v-belt alternator pulley wheel – 180g
Steel multiribbed belt pulley wheel – 495g (inferred estimate)
Alloy multiribbed belt alternator pulley wheel – 100g
Alloy multiribbed belt crank pulley wheel – 220g

That’s another 340g saving over the steel versions, so the total saving for my setup is 4.6kg of which I estimate that 1.5kg is rotating mass.
