bee Posted September 24, 2010 Report Share Posted September 24, 2010 Got the 01 running nice, timing seems good, but I'm slowly losing coolant through a weephole in front of the water pump. Anyone had this problem? Quote Link to comment Share on other sites More sharing options...

gjbiker Posted September 25, 2010 Report Share Posted September 25, 2010 This is letting you know your coolant is passing through the outer water pump seal. If your gearbox oil starts to emulsify (turn milky) then the inner seal has gone as well. In a nutshell - you need new water pump seals ! Check the impellor shaft for damage while you're doing the job as this may have been the cause of the seal failure? GJ Quote Link to comment Share on other sites More sharing options...
bee Posted September 25, 2010 Author Report Share Posted September 25, 2010 Kinda what I was thinking. I've had the bike for a couple years and just started riding it this year, and the fella I bought it from didn't ride it much. Could be from sitting around for so long. Sherco's website has a great parts manual that shows 2 seals. I've never changed these in a bike before--is it a bugger of a job? I'm riding tomorrow so maybe I could jam a small screw in the hole with some permatex tonight............yeah, that'll work! Quote Link to comment Share on other sites More sharing options...
gjbiker Posted September 25, 2010 Report Share Posted September 25, 2010 Simple enough job if you're handy with the spanners and reasonably achievable if you're not? Just dismantle as per the image, carefully remove the old seals and carefully fit the new ones - simples You're 'block the hole with a screw bodge' will work for a while but keep an eye on that gearbox oil (and of course your coolant level)! Once the outer seal has failed the coolant pressure may cause the inner seal to fail as well? GJ Quote Link to comment Share on other sites More sharing options...
bee Posted September 25, 2010 Author Report Share Posted September 25, 2010 Just razzin about the screw. But I'll be sure to bring some extra green juice for the rad!! Quote Link to comment Share on other sites More sharing options...
ormplus Posted September 25, 2010 Report Share Posted September 25, 2010 if its a 01 sherco it has only got one seal in it .i would fit a shaft as well,the shaft is a bit pricey but if you dont it wont last to long. Quote Link to comment Share on other sites More sharing options...

Not being picky about your post but...... The diagram above is from the 2001 Sherco parts book and clearly shows 2 seals (part No: 1.24)? If there was only one seal then the 'tell tale' weep hole wouldn't be there? Would you change you're crank just because the crank seals are passing? If there's no visible damage to the shaft (pitting, scores etc) then a new seal should suffice? Nobody wants to spend more than they need to do they?

bee Posted September 25, 2010 Author Report Share Posted September 25, 2010 it does look like 2 seals in the diagram, but I'm having a hard time with it. Looks like a seal on each side of the case, but I've never been in there before. If I have time tomorrow, I'll rip it open and have a look, and let you know how it goes. Had a blast today. Brought plenty of fluid with me and it seems to be leaking abour 16oz. of afreeze per tank. I can almost live with that! Quote Link to comment Share on other sites More sharing options...
tony27 Posted September 26, 2010 Report Share Posted September 26, 2010 It's not a big job to replace the seals, the seals do go in from each side. The reason that you may have to replace the shaft is that the seals can wear grooves into the shaft where they run Download the manual pinned above & you'll see just how easy a job it is Quote Link to comment Share on other sites More sharing options...
copemech Posted September 26, 2010 Report Share Posted September 26, 2010 As stated, check the pumpshaft for heavy grooves on the seal riding area and replace the shaft if the grooves cannot be polished out with crocus cloth. Note that the seals oppose each other(hard side)in the case orientation, each sealing in it's own fluid and a gap between as the weep hole is located, which inhibits fluid transfer between the two. Set them correctly! Quote Link to comment Share on other sites More sharing options...
neo Posted September 26, 2010 Report Share Posted September 26, 2010 You'd be crazy to carry on riding the bike with this problem....blocked hole or not!! All the ones I've done have had scores on the impeller shaft so I'd budget for a new one if I were you....sorry! Best of oil and water balance.

ormplus Posted September 26, 2010 Report Share Posted September 26, 2010 done a 01 last week and only had one seal. Quote Link to comment Share on other sites More sharing options...
bee Posted September 26, 2010 Author Report Share Posted September 26, 2010 I probably won't have time to crack into this for a couple days, but I'll let you know what I find. 1 seal or 2, and the condition of the shaft. I'm gonna email right now and find out how long to get parts. ~B Quote Link to comment Share on other sites More sharing options...
trialsnutterman Posted September 27, 2010 Report Share Posted September 27, 2010 Sherco bikes up to frame number 003530 came with just one seal, so it possible your bike may only have one seal. Quote Link to comment Share on other sites More sharing options...
