mikeyb Posted February 15, 2011 Share Posted February 15, 2011 Yes water is getting past the seal - but if leakage is not massive, try running it for a bit - this has worked for me in the past. You may be lucky as I was and find that a bit of useage will polish the rust off the seal face and it will re-seal itself again. Link to comment Share on other sites More sharing options...
flipp Posted February 15, 2011 Share Posted February 15, 2011 try running for a couple of hundred miles if leak is not bad,as I have been told that some of the seals by way of design will leak until until they bed in. Link to comment Share on other sites More sharing options...
Nick Jones Posted February 15, 2011 Share Posted February 15, 2011 Tell-tale hole is best at the bottom as this lets the water out before it has the chance to build up in the housing and flood the bearings. Although if the seal leaks badly, that is academic anyway.Might be worth running a little longer to see if the leakage stops. Shouldn't leak from new though.Nick Link to comment Share on other sites More sharing options...
