Picture of the inside forward pulley plate off a Vespa moped (Si)that has split like a ripe watermelon!!!
Tempered steel used here????
PS Looking for a replacement pulley plate!
a very abrupt stop.
Actually, don, no stop at all..Belt lost tension and quit working and I coasted while the motor still turned.....Just gives you a feel for the heat and speed in that area...Also, I think the belt sliding over it for 20 years has just glazed it until it is brittle...
I did find a replacement part for it...
yea its just a standard sheave pulley.
I had some spare parts from an old Grande engine Don...The washer with the bent up side was the only thing holding the variator on, so there was serious vibration before the metal cracked. Back together and runs MUCH quieter!!
