Sorry it's only a 'little' engine!!. In desparation i'm going to throw this thing soon if i can't get to replace the impeller:- Story so far: <br />1. Got bottom of leg off, no problem<br />2. The housing for impeller broken, but can replace<br />3. Outer s/s tube removed<br />I am now left with the inner drive tube still attached to the impeller/gears & the impeller cannot pass over the drive tube as the hole in the impeller clearly won't be big enough!!<br />HOW ON EARTH DO YOU REMOVE THE DRIVE TUBE? SO I CAN GET TO THE IMPELLER?? <br /><br />Thanks anyone that can help, i'm in despair..!!!
