Stripped bolts on harmonic balancer

[fixkick]

Thanks. It looks like I'm going to have to remove the 17mm. I don't have an impact gun anymore.

Is there an easy way to lock up the engine without crawling under to lock the flywheel (my back can't take that)?

use 1/2" drive breaker bar. 94ft/lbs is spec, torque , and takes maybe max 150 to crack it loose, if at spec. now, many are not, and have damaged key slot.
but locking the transmission is real pain.
only way is at the front clutch inspection port

here is my lock page.
every way, but loose, errr,,, off.
