Pics of the removal and install, this took me 4 hours as things happened to work out. If the tool to hold the crank position was blocked by my under tray then more time would be needed. The car was not put on jackstands
This repair is not for a novice as the torques on the crank pulley are extremely high. I didn't show removal as I put the bolts on last time not to the outrageous factory torque so they were easier to remove. And I didn't show great detail because the way I did it is not recommended.
HOWEVER, with the long Carlyle tool removal is the "reverse" of install, and would likely need the car on jack stands and a friend to hold the motor still with it while a LONNNNNNNG breaker bar removes the torqued bolts, like 3 ft or more long.
OEM and VAC units weight 7.2lbs.or 3.27Kg
This is not a hard repair. I replaced all of my pulleys most of these are 170K to 200K+ miles old
There was cracking of the OEM balancer polymer. When these fail they take the motor as the crankshaft gets trashed, nevermind the block maybe the bearings would save it if you are lucky. I have read that 3 years is a prudent life cycle for heavy track use cars. It will fail at max RPM in all likelihood so tick tick tick. This motor was from a SMG convertible and 150K miles on it. I have put 20K Miles on it since June, 2021. No more worry bead!
