Righthand Crankcase Cover Bolts removed revealing the new DMR-JAPAN Water Pump from WEBIKE JAPAN previously installed due to the old Plastic drive gear cracking (not surprising given its age, bit like me really).
The MC28 Water Pump differs to the MC18/21 regarding the number of teeth on its drive gear, MC28 has 25 teeth and the MC18/21 has 26 teeth so made sure I got the correct pump. The one I chose was Product E4-28005 from WEBIKE JAPAN as it came with the Seals & Gaskets, although it is also available as separates’.
General Components under the Dry Clutch Housing Cover.
