so I decided to do the pump, based on the advise from some of you guys on this forum.
Its worth noting that if the pump main seal is going then yes you get loads of little leaks and the coolant dripping out the weep hole
, please look at the pic where I highlight with yellow how the impeller was rubbing up against the casing.
Now when we look at the pump we can see that the milled in Chanel takes the water out through the hole we see in the left hand side cover - the leak the factory is telling us is normal.. ye right. The coolant leaks in behind the impeller and this escape Chanel stops it from running out the shaft and into the oil...the pump is driven from a set of deralin gears behind the clutch basket all in the sump/gearbox oil
What I have learnt is that my seal was going and the pump is not serviceable and a new unit must be fitted, so I will report on that in a few days.
I was also sucked into the weight reduction thread on the forum, so I pulled out the servo motor and cable that controls the flapper in the exhaust pipe, now I will remove this nasty little flap as well since the thing is pieces.
In other thread I see guys left the thing is as its a pain in the ... to get too, I will post a pic later tomorrow when I have removed the flap it does not look like a big thorn to sort.
I can only hope that after all the effort to do the pump I get rewarded with a bike that does not leak. Not wanting to wine on but guys if your bike is dripping any coolant from the little hole the the seal is fuked and you need to get on it.
I cant wait for able and Halo and other to rip into me again for moaning
