Jakesherco250 Posted September 26, 2017 Report Share Posted September 26, 2017 Hi guys, looking for some advice into the source of my problem, I have an 06 sherco 250, I replaced the water pump seals and bearing as it was leaking from the weep hole and it fixed it however after about 4 hours of riding it's started again. I had no leaks whilst I was riding it on Sunday, I washed the bike fired her up and there was no leaks then but the next day when I fired her up its started leaking again. Any help what this might be is much appreciated. Tia Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted September 26, 2017 Report Share Posted September 26, 2017 You might try in the Sherco section rather than the general forum? They might already have this answered there. 1 Quote Link to comment Share on other sites More sharing options...

dan williams Posted September 26, 2017 Report Share Posted September 26, 2017 A 15 year old that works on his own bike. That's excellent. Even if you don't get an easy answer rest assured that all the cranky know-it-all's on here (yeah me too) started the same way and there's lots of times we put something together only to have to take it apart again and fix it proper. It's how we learned. It's how you'll learn. Welcome to the brotherhood (and sisterhood) of "I can fix that!" You are now one of us. 2 Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted September 26, 2017 Report Share Posted September 26, 2017 (edited) Most likely the shaft is worn where the seal rubs. Edited September 26, 2017 by 2stroke4stroke Quote Link to comment Share on other sites More sharing options...

Jakesherco250 Posted September 26, 2017 Author Report Share Posted September 26, 2017 Thanks 2stroke4stroke I'll have a look into it, when I took the parts down to my local bike dealer he said the shaft looked pretty well but I suppose if it's started again after 4 hours it could have worn down, just baffles me why it was the day after Quote Link to comment Share on other sites More sharing options...

Welcome! Also thought you would like to know we had bike specific threads so you could search and ask direct questions to others that would give faster response as they share bike brand with you.

2stroke4stroke Posted September 26, 2017 Report Share Posted September 26, 2017 As it separates oil from water then potentially yes, but the water is at much higher pressure so more likely to migrate to oil 1 Quote Link to comment Share on other sites More sharing options...

pauls320 Posted September 29, 2017 Report Share Posted September 29, 2017 Make sure you get the seals installed the right way....tension springs have to be towards the fluid side that the are sealing in....and the bearing has to be on the transmission side of the oil seal....the factory parts diagram I have seen shows the bearing between the two seals, which is not correct. Hope you get rolling again soon Oh ya, welcome to trialscentral Quote Link to comment Share on other sites More sharing options...
