Changing an impeller

We have a honda trash pump, model wt30x, and we sucked up a screwdriver which shattered the impeller. My question is, how does one unscrew the bolt holding what's left of the impeller? I can't figure out to keep from turning the drive shaft so I can unscrew the bolt. (I hope this makes sense.) Thanks.

Re: Changing an impeller

take out the spark plug and push some flexible rope in there then when it comes up on the compression stroke it will hold the piston against the head.

Re: Changing an impeller

When i changed ours, i just held the impeller with one hand(wearing a glove) and used an air impact to remove the bolt. I did the same thing when i put it back together.

Re: Changing an impeller

If you can't find a place to hold on the crankshaft...

Here's a trick I learned from an old motorcycle manual. Remove the sparkplug, move the piston to the bottom of the power stroke and put some rope in the spark plug hole which will keep the piston from coming all the way up. Make sure its the power stroke so the valves are closed (it was a 2 stroke bike book so that wasn't an issue.

However, I would just hit it with an air impact gun to jolt it off quick before the shaft gets the chance to start spinning. Make sure you know which direction the bolt goes first though!

looks like i proofread too long and everyone beats me to the punch!!!
