Tex Jan the wheel is rusted to the shaft. After you remove the derusting treatment You can use a small wheel puller to remove the wheel but be very carefull. As you tighten the puller tap the wheel with a wooden mallet or rubber mallet. I have done this several times. You can also use a penatrating oil to loosen the wheel, but you know this already. I really got to get me some evapo-rust!! Glenn
