    LF: Beta/Sachs CC Forks Damper Rod Seal

    Seals like that can be used as a piston and a rod seal. thats why they have a symetrical crosssection. "K95 is a single acting piston - rod seal and designed to have symmetrical lips in order to be used both for rod and piston applications."

    To be honest i just guessed, they are all rated to 0.5m/s. Theoretically to low, but i didn't find a V seal thats rated to more. If the K95 seal leaks im probably going to try some other geometry and maybe a PU seal instead of nbr.

    As i said, i didnt put them in my forks yet so i cant guarantee anything yet. But they look exactly the same. I contacted Kastas directly, which directed me to their german distribution center that could tell me who sells them in my country in small quantities. I can PM you their email, but i would ask if there is a distributor in your country to save on shipping. I attatched a picture of the seal i recieved.

    Perfect thank you. The seal should be the same, mine looks like yours. Im going to try building one out of wood, i just have a lot going on right now so didn't get the chance yet.

    Sachs CC Valving

    RR300 Racing 2018, no not as far as i could tell. But i didn't look for one, should have seen it when disassembling the BV though.

    Sachs CC Valving

    I went to 0.3, just to test it out. But damn, i dont know who worked on the other fork, i sure dont hope it was at the facotry. A 24mm shim at the end of the stack(float ajustment?) and a giant crossover because of 2 shims that definately didn't belong there. I just build the stack like the other one. Im really looking forward to testing this out tomorrow. Also the oil was quiet dark inside the cartridge compared to the other side, those sachs parts definately are nowhere near the quality of the jap stuff. Im curious how long they will last, already hardcoated the outers at 50h.

    Sachs CC Valving

    Hello, first of all i dont know for sure what stacks are in my fork. The ones i have are off the internet. Im going to check when i open my forks up. I just cant ride much and want to do most of the thinking prior to dissassembly so im not in a rush and they dont lie on my table for a week. 16cst Oil is pretty expensive around here, so im mostly running 20cst. This makes my valving a bit softer. I mainly want them to move more, im close to all the way out on my comp clicker and they still are quiet stiff, pretty much every where. If you want to compress them before an obstacle its quiet difficult too. We almost excluisively have brutaly hard packed tracks with lots of sharp hits here, so i prefer a softer set up. The stacks below look very weired, i only worked on SSS forks before when it comes to closed chamber ones. What do you think? Edit: I just pulled them apart, and well loook for yourself. Just 0,1mm Float!! Base 3x25 16 2x25 24 23 22 2x20 18x0,15 16x0,15 14x0,2 12x0,3 13x2,05 Mid 19x0,1 2x20x0,1 15x0,1 13x0,1 4x11x0,2 11x0,35

    Thanks for the info. How hard was removing the seal head from the cartridge tube?

    They still have to fit, im going to keep you posted. I'll know next week. Have to build a cartridge holding tool and race on saturday.

    LF: Beta/Sachs CC Forks Damper Rod Seal

    I think i maybe found the original manufacturer and the part, what do you think? https://www.kastas.com/goster_ou_ayrinti.php?tt=20190710091038&l=3&f=c117579e12b3865c57e1e90a2c407yyy&id1=63&id2=14052 that would mean that i can use every rod seal, theirs is only rated to 0.5m/s also. Update: Just ordered 10pcs. for 1.69€ per Seal, im going to let you know if they fit.

    Do you remember the OD? 20? Or is this just part of the part number? I was wondering if you could use off the shelf hydraulic rod seals, they even come in blue and look very much like the kyb/wp/showa seals, but hydraulics usually have very low movement speeds, the seals are rated only from 0.5-1m/s. They look and feel exactly like the ones in forks through. I even found one in 12x20mm.

    Grat, would have been too easy. WP used a OD 19mm seal and showa 18mm IIRC. The height wouldnt matter, i can turn some small spacers. Adapting the OD is difficult though.

    Sadly i cant just disassemble the cartridge this far in the middle of the summer, when im near my bike i want to ride. I was thinking that maybe a showa/wp seal would fit, maybe with some modification. Im just going to hope that the seal doesn't fail till winter when i have time to do some tinkering. Damn, spare parts on this sachs stuff is really a pain. But switching to kyb is not an option after i hardcoated the outers and paid the extra money for the racing modell. Your always smarter afterwards

    Sorry for digging this up, what dimensions does the seal have? Can't find a seal specifically for the Sachs fork on JBI's website. Cant see it on the picture either.

    RR300 2018 Spring Rates

    One general question about fork springs, the 4.6N springs i had laying around were out of an KYB 48 OC fork, on aftermarket springs both this bike and the RR fork springs are listed, 460x 43.5mm. Now i wanted to change the springs and was in for a bit of a surprise, the lengt actually was the same but the KYB springs have an OD of 44mm, which makes them more of a snug fit in the Inner tubes, no binding etc but feels "tighter". Im going to polish them on the lathe anyway, do you think this matters friction or wear wise? The stock springs on the Beta are very small on the OD, only 42.5. Normaly the springs listet for this bike are 43.5. Edit: Never mind, i polished them up a bit and they slide freely in the inner tubes. I think they fit quiet well.
