This is the blower out of my 1967 GMC PD4107 bus. This bus was converted to a RV 30 years ago then left sitting for 23 yrs after the owner moved south. Its powered my a 8V-71 Detroit diesel and a Spice 4 speed manual transmission. All attempts to get the motor turning over resulted in failure, after much investigation the supercharger was found to be the culprit. we removed it and this is the process of rebuilding it. Remember, I'm an amateur when it comes to this stuff and this video is meant to be entertainment not instruction.....
