Ok I am pretty sure that you have just been confused, thats all. There may have been two available crank seals available for the front crank seal, and since you had one that doesnt fit,...... it is the wrong one. The one that does fit i suggest that you install that one after removal of the one you are replacing. The only other crank seal would be the rear main, which would be significantly larger and you would have to remove the tranny to replace such seal. There is only one front crank seal, that is why you cannot find "two" in the repair manual. Also confused as the cam seals because it is a twin cam engine and would require "two" seperate seals, one for each cam. At least that is what im sticking to untill i get to work tuesday and ask some veterans, and look through the Toyota repair manual. By the way, this is Kevin from the dealership.
