How much clearance should there be between a stuffer and impeller? I'm installing my new split bowl and doing some final setup for this weekend and When i put the bowl on (without a bowl Gasket) and rotate it the impeller face is showing slight rub marks on the top edge..
Does the impeller need to be shimmed back? or is it a combination of no gasket and the bowl not being tightend down even?
thanks
Maybe Duane can come up with an "ultimate" stuffer that self clears! :rollside:
You don't want to "shim" your impeller to clear your stuffer, that will change your internal clearances, which are more important. Besides, if your impeller is already "clearanced" properly, you'd likely run it into your wear ring shoulder or suction hsg. NOW...if you haven't checked your impeller clearances to the front, you might need to move it forward, but not arbitrarily to clear your stuffer. You can't shim it forward, either, unless it has been shimmed back. To move it forward, your shaft has to be machined. :coffeycup
