Hi,
Hi,
I have worried about this from time to time but always got it off somehow. You can lock the crankshaft by putting something through the fins of the flywheel. Youtube videos showed a piece of wood. Problem here is that puts all the torque on to the flywheel to crankshaft joint. Its only alloy located by a flattened section on the shaft, no keyway. I have damaged the flywheel like that, not while getting the blade nut off but when torquing up the blade nut when refitting. Not much risk when removing though as its usually pretty much rusted on. Once I locked the shaft by taking the starter off the top and putting a piece of wood between the conrod and the shaft. Worked fine, no damage but refitting not removing.
The PT's are difficult to lock, not like a full crank which at least has the nut on the top.
Norm, I have never had a rattle gun & do not have any idea about them. Bunnings have "impact wrenches" quite cheaply. What do you have, might give me something to go on? Do you still have to lock the shaft?
All the best
Jeff
