Thats just what we needed Oldgrump, thank you. Have located a seal set but cannot see if it's a lipped seal or not, will read the manual tonight to see if we need to split the crankcase! Tim

I am told It's a Husqvarna cr 125 2007. I will check out the dealers, thanks again. Tim

Thank you oldgrump for your reply. I will try and locate a manual and spec the seal. Can anyone suggest a good uk parts supplier for this make of bike, if thats allowed? Tim

Thank you Mike, Struggling to get the photo to attach? Will give it another go. Tim

Hi Everyone, I am new to this forum and hope you can offer some advice on a problem with a Husqvarna 125. The bike belongs to my neighbours son who recently purchased the bike in supposedly good running order. Unfortunately it seems it has been in the hands of someone who has not been to kind to it in the past. Having some mechanical knowledge I have offered my help to try and sort out some of the issues, my main interest is with vintage stationary engines so this is a little different for me. The problem we have at present is oil leaking from the casing on the ignition side. I am guessing this is a crankcase seal gone or maybe the bearing as well? We took the cover off and found what is in the photo attached. My questions are; I presume the centre nut holds the rotor on via a woodruff key...would this be a right or left handed thread? Can the seal be accessed from outside or will the engine need to be split? Hope someone can offer some advice about how we proceed next, it's been a frustrating journey so far for the lad. Thoughts appreciated. Tim Husqvarna%20125
