Fork Seal is Stuck
Hey Guys,
I've changed my fork seals a couple times before and had no troubles what so ever. However, this time the fork seal is incredibly stuck and no amount of slide hammer action has made it budge (more than 1 hours worth). The silvery part also gets stuck at the top of its range when i pull really hard (probably because all the oil has drained out and it's dry as a desert in there). I used the search function and nothing of this nature has come up. I know there is a trick with a long ass bent screw driver which you shove down through the bottom but i don't have one of those and i don't think that would work for the ninjette. I've also tried heat (heat gun) to try to make the seal a bit more malleable but that hasn't worked either... Anyone else had this problem and managed to fix it? *EDIT SOLUTION* Turns out the issue was that the fork bushing (44065A) was stripped to hell. I don't even know how it happened... All i know is it required a vice, Lots of elbow grease and lots of regular grease (WD40). I had to take it into a shop to get it done as i didn't own a vice and pulling outwards against myself just wasn't working (now i see why). Yeah.... I don't even....

WD40 or other penetrating liquid wrench type lubricant may help.

I'm kinda of confused because I can't imagine a seal getting stuck. Do you mean the the rubber seal(92049) or the metal bushing (44065)?

Ive seen Randy from Inhouse Suspension heat up the fork tube with a torch before pulling the seal out. You can try that. But first, answer what Dino74 asked because if it's the metal bushing, if you replaced them for new ones, you could be installing the wrong ones. (Don't ask me how I know with regards to my Bonneville)...

Thanks for the responses,
It's the rubber fork seal (seated under the dust seal and metal retainer clip). Generally the thingo you replace when the forks are leaking oil. I know about the heating method but a torch isn't available to me and i've tried a heat gun. I'll give the wd40 option a shot later in the afternoon and report back Thanks Ed |

So WD40 didn't seem to do a thing. As i move the fork tube (silver) away from the bottom end (black part) it seems to be hitting a bit of resistance and ends up getting stuck in the seal. I usually use pyramid fork seals but this seal is from a dealer as i didn't have time to wait for a shipment.
I'm going to leave it overnight Drenched in wd40 and hopefully something will come of it tomorrow morning. Oh, i also tried heating it (heat gun) for an extended amount of time (rubber was smoking) to no avail. In the meantime, does anyone else have any suggestions? |

No dice
I managed to remove a little spring that sat around the entire fork seal and that didn't help either. Off to the dealer i go i guess. |
