Re: WATER PUMP LEAK
the seal has failed inside the pump, problem is i dont think the o-ring is listed as a part you can buy either.
if you remove it and cant get it matched, then replace the whole pump with another good used one.

Re: WATER PUMP LEAK
buy a new waterpump.
As crm has said it isnt servicable. it will eventually sieze and snap (had it happened beofre)
the Honda book says to replace also..

It can be repaired on some bikes..but not this one.
Easier and cheaper to get a decent pump and replace it in one go. Easy.

that o-ring stops the oil from leaking out the engine.. it doesn:t stop the water.NC 35 owners wrote:I when to bike shop they say it's can be repair ..I did it my self once and I change the o-ring that going inside the engine and the gasket between the pump but it's still the same leak again
the water pump o-ring on the nc30 is inside the waterpump you cannot get out

I brought 2nd hand pump from good bike for cheap, it was in very good condition and still works good now.
