Stuck crank pulley bolt on m275
I'm trying to get my m275 crank pulley bolt off but it's impossible right now. I finally found a counter holder that would fit (after some filing) and used a 5ft breaker bar and my entire weight (155 lb). My socket extension just snapped and now I have a hole on my AC condenser too.
Would prefer not to take entire front end off.
Any tips or ideas?

Other than a bigger bar and extension, it sounds like you are doing it right. If the counterholder is doing it's job, just put a longer handle on the bar (piece of pipe, jack handle, etc), and go for it. Try not to break the fenders

I broke 2 1/2 drive tools. Ordered a 3/4 inch socket so let's see how that goes. I have a floor mat protecting the fender :-)

Name brand tools or cheap junk? Makes a difference.
I've seen one snap-on breaker bar break, it twisted the end off. Had about an 8' extension pipe on it, with a 250lb person jumping up and down on it.

This post brought back some good memories. 
Here's the set up
Get the Husky breaker bar from Home Depot. It worked for me.

The 1/2" equipment might not be enough. I had the same problem on a Porsche 928 crank pulley. I snapped a Craftsman 1/2" short extension bar in the center. I could feel the extension and pull handle flexing before it broke. I used a 3/4" drive socket, extension and pull handle, and the bolt moved with no problem.
