Flywheel access is too small for hammer handle, but now that you mention it, i may be able to wedge the scredriver i was trying to hold by hand (while my son tried to turn the bolt) with a 4x4. Going to pick up some penetrating oil in the morning and stop by a few times during the day to shoot it with that too.

Not enough space for impact wrench, might an air ratchet offer enough torque? I'm new to air tools, have only an impact (old, marginal) wrench, but willing to accumulate.

Thanks again.
