How do I remove the Impeller assembly from my model series 410 Troy-Bilt chipper shredder. It has a Briggs and Straton 8.5 hp engine. I need to replace the engine but without being able to remove the impeller I can't detatch the engine from the unit. Larry
There is a special tool to remove the impeller. You may be able to borrow one from a local shop or take it and pay them to take the impeller off for you. Here is a link to get the tool.
