RCK5423BX sn14668 deck. Shaft on spindle is not like the parts list k5371-34552 looks close but their is no bushing over the top bearing, their is a fixed washer ( lack of a better description) same size of the bearings inner race. Do not see how to remove shaft. Bearings are bad. No snap rings, tried to unscrew the upper to lower shaft I'm at a loss.
