Honda 1988 CR125 Water Pump Shaft Alternative Gear (Plastic vs. Metal)
This water pump shaft worked like a champ in my Honda 1988 CR-125 that took a plastic water pump shaft gear. The 1988 shaft gear was part number 19240-KS6-700. This water pump shaft gear is for a 1997-2002 and is a improved metal gear 19240-KZ4-620 used in later CR125. This water pump shaft gear is a gear alternative for the early CR125 models. Hope this helps others out.
