The front bearing will press out from the rear once the crank is removed. There is a oil seal back there behind the bearing that will be damaged when you remove the bearing so replace it also.

Some heat and wood dowel works to push to the bearing out from the rear.

Or you could send it to YS parts and service they will look it over and fix any problems...You may have more probelms thatn justa bearing. Besides they work cheap and get the work done properly.
Besides you already have buy the bearing and the oil seal it won't cost much extra to have them go through and do the work for you. Probably less than the parts costs...they can give you an estimate before they do the work if you request it. Richard and crew are really good at what they do.
