jeff408 Posted June 26, 2020 Report Share Posted June 26, 2020 Hi all, Jeff here from Randle (Gifford Pinchott). I just bought an used 2019 Bete Evo 300. It had leaky rt fork and I'm trying to put in new seals in it. I'm trying to remove the bolt on the bottom of the fork. With the forks off I used an air impact gun and it loosened it enough for the oil to leak out. Now it just spins and I've researched the internet and cant find what I can do. Any help would be appreciated Thanks, Jeff Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 26, 2020 Report Share Posted June 26, 2020 Put the forks back together and put tension on the fork spring, even if it means going back on the bike. Quote Link to comment Share on other sites More sharing options...
misscrabstick Posted June 26, 2020 Report Share Posted June 26, 2020 I have had past success by stuffing a broom handle down the open fork leg to hold the damper, never tried on a Beta though. Quote Link to comment Share on other sites More sharing options...

It is the rebound side with no spring. I made a tool that I though was stopping the internal damper from spinning and that didn't seem to work. Maybe I'll have time to dig in more over the weekend. Anyway thanks for the responses Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 27, 2020 Report Share Posted June 27, 2020 (edited) I think if you take the top fork nut apart, you could also just use a pvc pipe to make a tool. Edited June 27, 2020 by lineaway Quote Link to comment Share on other sites More sharing options...
reggie Posted June 27, 2020 Report Share Posted June 27, 2020 Sometimes a hand impact will work better than the air one, or maybe a different air or electric impact may work. Some of these fork were put together with too much thread locking compound. Good luck. 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 27, 2020 Report Share Posted June 27, 2020 That sure is a beefy bolt compared to the old style. Quote Link to comment Share on other sites More sharing options...
jeff408 Posted June 29, 2020 Author Report Share Posted June 29, 2020 Good news guys I got the bolt off. I bought a good electric impact and held the damper from the inside. Thanks all Quote Link to comment Share on other sites More sharing options...
jeff408 Posted June 30, 2020 Author Report Share Posted June 30, 2020 (edited) Today I put new SKF seals and put it all back together. So now to add fork oil. I decided on Motul 5w. My new dilemma is how much to add. All my manual says is 297 g either side. Looks like most things I see on line are talking air gaps like 65 on rebound side 120 comp. side so different volumes. I'm looking for oil volume on rt side any thoughts on this? Edited June 30, 2020 by jeff408 Quote Link to comment Share on other sites More sharing options...
jeff408 Posted July 1, 2020 Author Report Share Posted July 1, 2020 Got it all done. Just add 297ml pumped damper and it came out right at 65mm air gap. Thanks again, Jeff Quote Link to comment Share on other sites More sharing options...
dan williams Posted July 27, 2020 Report Share Posted July 27, 2020 You’re a better man than I. I tried to drop the fork on my 2018 to look at the internals and ran into the same issue. Screw loose but not releasing. Couldn’t get it to tighten either. Much bodging of tools and many bad words later got it back in and haven’t touched it since. I’ve been into a lot of Paiolis but these Sachs forks are a different animal despite looking the same. Quote Link to comment Share on other sites More sharing options...
jeff408 Posted July 28, 2020 Author Report Share Posted July 28, 2020 Ya, I'm not sure if I got lucky or not, But keeping the inside damper from spinning and help with the impact gun on the bottom end. Quote Link to comment Share on other sites More sharing options...
