Re: Pulled clutch and can't remove screws behind it even with an impact, also no wood
At 7min 20 seconds into the video it looks like there is the puller being used. It threads into something on the engine. The monkey wrench holding all from turning while using the large Allen wrench loosen the crank.
Thanks for that link!
Sorry you've got no wood man. That's gotta be he11.
That puller is for the sprocket, same one that pulls the clutch.
A small one pictured below comes with your engine or can be bought for $2.99.
The threads in the puller may not fit the sprocket or clutch well. Be prepared to chase or file them deeper for better engagement. Need 2 full turns of engagement minimum or risk ruining the threads, completely painting yourself into a corner.
Not all engines come apart as easy as Fred's.
Press fits on the case and crank can be rather firm, plus the crank can burr on the magneto side shoulder (maybe the other side too?). File off any burrs, and heat the case with a propane torch to get the bearings out of the case. I like to get the crank out of the bearing first, then deal with the case.
People put locktite in the darndest places, heat is your friend if it doesn't move. Just enough to smoke the oil.
Lost woodruff keys are common. They go flying when you pop it apart, quickly lost in the grass or under the bench. Cheap to buy, get a couple just in case.
