so having had a look down there a few times ive noticed that when i got mt new engine i gained a aluminium pulley. was that always there? is it standard? i assume its ali, im very used to looking at ali and steel and spotting the difference at a glance and it looks like ali to me

it'll be a lightweight pulley mate... the originals are big heavy steel...

more like cast iron than steel :wink:

guess il be whamming a magnet on it to prove my suspicion

more like cast iron than steel :wink:

 

Thanks what I meant, damn predictive text :whistling:

If it's shiny it'll be an ali one if it's rusty it'll be the old nasty one :)

Think the standard ones are steel the weight comes from the heavy rubber mass inside the pulley [harmonic damperner ].

well whatever it is its non ferrous. ie not cast or mildsteel. i whacked a magnet on there and it didnt even try and stick. the oxidation on the surface looks very aliuminum like to me. looks like i might have found a little gem :D
