Parts for The Pool Cleaner seem to only be sold as kits, adding significant unnecessary cost. Does anyone sell specific parts? For example, I'd like a steering shaft, yet they only sell it as a steering assembly kit (part # 896584000-136). The same holds true for the front right gear drive assembly (luckily, that shaft can be reversed when one side is worn). I'd appreciate being put in touch with a source for parts rather than just kits.
