Impeller removal help needed
Hey guys,
I am trying to remove the stock impeller off the driveshaft. I'm using a 12" crescent wrench as well as a torch with no luck. Yes, I am turning clockwise because of the reverse threads. Damn thing does not want to budge. The crescent wrench keeps slipping from the torque and Yamaha's brilliant design on the impeller "nut" doesn't help any. My question is what size wrench would I use on this? I'd like to try the closed end of a large wrench to eliminate the slipping. Anyone know or have any ideas that would help?

Fusion.
Get yourself 2 3FOOT pipes to slip over the wrenches. Once you get your wrench sizes down, those pipes (handled with care) are life savers.
The real problem is that the driveshaft absorbs soooooo much torque, that it makes it like a spring holding tension, until it "pops." If it could have been held at the back of the pump like most others, you wouldn't need such large amount of leverage.

Thanks guys! Ended up borrowing a 24" pipe wrench from one of the maintenance guys at work. Damn thing weighs about 30lbs. Impeller broke loose on the second try WITHOUT any heat. It's amazing what the right tools can do for you
