I tried using the starter to break the crank pulley bolt free, but unfortunately that wasn't adequate. Any other ideas for a guy needing to get this pulley off while the dealer is closed and the proper tool isn't available?

A very long breaker bar will do the trick if you dont have a impact tool. Good luck... your going to need all the leverage you can get and getting the car on the lift is the only way I can think of doing it.

SpeedxRacer - I take it you haven't removed one of these.

There is really no way of removing it without an arresting tool and a long breaker bar. You can't get an impact wrench down there because of the cross member and even if you did I'd be surprised if you could get it off without arresting the pulley.

I made a tool out of a 50mm nut and bar. The bar rested against the foot of my shock tower brace. I then used a 19mm socket on the bolt and a 50cm breaker bar. When it wouldn't budge I got a length of steel pipe on the end of the breaker bar and used my not inconsiderable strength and weight (not necessarily in that order) and after a few strains it came loose.

I'm surprised you aren't shopping for a new starter.

strap wrenches kick ass... i use mine on my pullies all the time...

I feel for you. I had to break the crank pulley bolt off a 1992 Accord with nearly 200k miles on it. It took a long breaker bar with lots of leg strength to break the bolt loose. I good sized impact did absolutely nothing. The crank pulley was already toast due to the inside pulley seperating from the rubber so I used a large pipe wrench to hold it in place.

What about putting the transmission into 5th or 6th gear and have someone step on the brakes?

I may be way off on this but it has been noted that it can take upwards of 500 lb/ft of torque to break that bolt free. Can our car's powertrain take that kind of load? I mean, you're basically putting 500 lb/ft of torque through the drive shafts, rear diff, prop shaft, tranny, clutch, and crankshaft.

The starter motor is electric, which is great for applying instant torque. Add to that the magnification of going from a small gear to a large gear and you can really apply some serious torque. I've used this method on multiple other vehicles without any ill effect, so I'm not worried about it.

In the past, I've had no luck with my impact wrench - even though it's rated at something like 350 or so Ft. Lbs. of potential force. I was going to buy some proper sockets and extensions this evening and give it a try anyway, but it sounds like the consensus is that I'll just move the car - which I also did when trying to breaker bar free that 19mm bolt using the drivetrain/e-brake to keep the car motionless. I agree that this sounds like a bad idea now though as it would tend to put a lot of stress on the drivetrain.

I like the home made tool that AusS2000 put together. Where might I find a bolt (50mm?) that large to use in creating such a tool of my own???

That nut is part of a hydraulic coupling used in heavy industry. It would probably be easier to order the correct tool from Powerbuilt.
