your not alone on the crank pulley bolt issue I usually :
1. Put the car in park w/ e-brake on.
2. turn the stearing wheel to farthest left I can.
3. Grab a jack stand to use as a pivot point.
4. grab only a 6-pt. 17mm socket for a 1/2 racket.
5. use a 10" or long 1/2 extention w/ socket on one end and the other end resting on top
of the jack stand.
6. grab either a large strap wrench and wrap around the largest pulley on the crank, or get
Honda's crank pulley tool and jam the lever end either to the ground or part of the frame.
7. grab a pipe about 5' to 6' long put on the 1/2" racket and connect the racket to the
extension.
8. With all the tools in place and the 1/2" extension resting on the jack stand position the
racket parallel with the ground slowly stand on the pipe the cheater pipe.
9. you will here a loud pop sound to signal the crank bolt has broken loose.
I have tried using an impact wrench on this even the 1000 ft-lb type and had no success.
I manage to make this work on a total of 23 d-series, 4 a-series, and 5 b-series successfully and as a routine I can get the bolt off in about 10 to 15 min. ;D
