First post, nice site. Did a search and could not find anything, was hoping someone could lead me in the right direction instead of a new pump. I have a 720K that has started to leak from the seal on the axle (final drive?) shaft. The manuel does not show any seals and it has to be installed from the inside instead of just pulling tire,wheel and hub assembly, popping out the seal and driving in the new one. Any help would be appreciated. Thanks in advance, Joe.
