Yeah, the lower bearing/seal housings are a trouble spot for these engines, prone to bearing wear/water damage. To replace the lower seal, one must first remove (and destroy) the lower needle bearing from the housing to get at the seal. I always used to just replace the complete unit, not possible these days. Unfortunately, the lower crank race was usually worn as well when water had damaged the lower needle bearing.
