    Fork Seals - Could Use A Hand in SoCal

    I'm getting ready to replace the fork oil and seals on my Hawk. The rear shock mount on the BMW broke off, so that's going to be more work to repair (fortunately it wasn't a crash!). I plan on doing the job tomorrow, Feb 2nd. If anyone local has experience and can help out, I'd be happy to pay (money, beer, eternal gratitude, whatever you'll accept) for some expert help, as it's not a job I've done before. I've also got a couple other parts to install (chain roller, WW rear brake torsion arm, and chain and sprockets), so depending on how ambitious we're feeling there's more to do.

    I really just need to get back to commuting on a bike again, the traffic is killing me in my car!

    If you can lasso him into a day.

    But I'm betting its not tomorrow. Great time to drive or shop though.

    He's a busy guy though, no promises!

        Do you have our Hawk owners instructions. That's the one. https://www.hawkgtforum.com/forum/ho...b-link?t=21134

        Disclaimer: its been years since i was in a set of Hawk forks.

        Tips off the top of my head , loosen the top triple clamp all the way before trying to loosen the fork caps. Use s six point socket on the caps. And they only need to be snug when reinstalled. Check all bolt torque specs.

        Get a long impact Allen bit for a impact driver for the drain. Pump the oil out over a drain pan when it slows down. Careful it shoots like a water gun.

        Slide the forks out like a slide hammer to remove the seal ( after dust wiper & the cir clip are removed)

        Make your seal driver from PVC pipe and a hose clamp to dial in the size.

        But i seem to remember a member saying the PVC couplings the appropriate size only needed the internal ridge removed to fit properly.

        Collapse the fork leg to put oil in, ( springs out ) add about1/2 of the manual spec amount of oil and then slowly pump the stanchion to burp the air; and finish adding oil up to your air gap measurement ( recommended method) quantity specs are a outline only. Not as accurate as a air gap measuring method.

        And a Racetech tip: is to use a thin plastic bag (produce market bags work well) put a cut off corner over the stanchion top and a tad of oil on it before sliding the seal over the sharp top of the stanchions. Avoids micro tooling cuts on your new seals. Of course the stanchions surface is critical for seal life.

        SKF fork seals are leaps and bounds better than most others according to our resident suspension expert.

        Add/ a large horse syringe or similar with a length of clear hose is useful for adding or subtracting oil. I get mine from my vet.
        maybe horse feed store would have them.

        A wood chop stick marked for your air gap spec.

        Turkey basters are not as easy to use in my opinion.

        If your garage has open ceiling joists use tie-downs to the frame top cross member under the tank. Or a heavy duty hook/eye. I use.my orange 6' fiberglass ladder straddling the frame and tie-downs to the same cross member under the tank. Loosen the front axel nut first while on the ground is recommended. Use a new cotter pin.

        Ill be around tomorrow,. Pm me & I'll shoot you my phone number if you need some help.

        it will be a full day for a first time adventure if you've got everything you'll need. Fortunately the traffic and stores will be easy tomorrow during the game.

        Good Luck Mr. Phillips

          I purchased SKF seals, the motion pro fork oil level tool, some maxima 15 wt oil, and I have most of the tools I’ll need. I should pick up the pvc coupling and hose clamp for a driver. All I need to do is make sure everything is ok inside and replace the seals. The plastic bag tip is great, I’ll do that!

              note: there is a copper? IIRC crush washer on the lower Allen bolts on the sliders. It can become stuck to the fork slider after the bolt is pulled. And can end up in your drain pan. Trust me ... you don't want to go fishing for them.. Ask me how I know.

                Hi guys!

                This one’s a little out of my element experience-wise ... on my first Hawk I’d been able to diddle with blending fork oils (10 & 15 to make 12 weight) and make fork tube inserts for spring preload, BUT had not replaced seals. On my second Hawk ... I cheated and changed the whole front end with USD CBR600RR components. CindyTurbo’s Hawk has nary a dribble or sheen indicating seal trouble ... so haven’t needed to undertake this procedure.

                Tim, I’d like to help, but this is kinda short notice for me. I can’t squeeze it in today. Otherwise ... Heck, I’d ride over just to watch and get in the way!

                  No worries, I'll give it my best shot and take pictures along the way so I can show everyone how it went!

                    Ok, so I decided to start by using the SealMate, and it worked. Rode to work today, no leak so far... now I have to get off my butt and do the other stuff the poor Hawk needs.
