can yuo change axle seal with out splitting case?...hydro gear 166768, 314-0510

this hydro is split vertically...instead of horizontally and has a spring clip on the end of the axle...the diagram shows a spring clip...then retainer ring...and then a lip axle sea...since its not the usual horizontal split transaxle but vertical I am wondering if I can just remove the spring clip and put the seal in from the end without splitting the case..any help would be GREAT!
