All of the new bearings are installed and I added zerk fittings to the sliders and control board frame.

That's bad ass! I look at the S18’s suspension as a piece of machinery so lubrication in hard to reach areas to me is important. 2 Quote Link to comment Share on other sites More sharing options...

Marek Fucila Posted September 22, 2020 Share Posted September 22, 2020 Hi, I just received my fixed S18. The wheel came in the first batch and after about 70km the mainboard gone. I sent it to seller then and they replaced the mainboard and improved the suspension as well. So this is how it looks and works.

I definitely Do Not think bushings have been used here personally! Note that spring washers have been put back under the heads of the bolts in at least 3 (6 total) of the visible pivot points. My guess is that the original bearings are still in situ, and then flat washers/spacers have been used between the bearings and the spring/lock washer/head of the bolt! I really would Not have expected to see spring lock washers being re-used in a suspension upgrade, but if they are indeed locking against a flat washer that is much more likely/safer than directly up against a bushing! 2 Quote Link to comment Share on other sites More sharing options...

True, that could be an internal flat washer. All I can say is that it doesn't look like the blue plastic/rubber seals on the original bearings. If it IS a flat washer they've stuck in there, it's likely defeating any bearing it's sitting next to by binding both races to it.

Popular Post NastyFartPants Posted October 12, 2020 Popular Post Share Posted October 12, 2020 I've done my own basic suspension mods This is it straight out of the box, shock disconnected My version did not have any spring lock washers, but it did have penny washers Minimal disassembly, the right hand side cover and batteries left in place I did replace some of the double bearings as they were binding due to not being accurately aligned! I then replaced the penny washers with M10 x 13mm x 1mm Flat Seal Washers so that the only contact was with the bearing's inner race. I lubricated the Stanchions, there were no blocks on the pedal hangers to remove Finally, the finished result 6 Quote Link to comment Share on other sites More sharing options...
Popular Post Meulebeest Posted October 29, 2020 Popular Post Share Posted October 29, 2020 (edited) Hi, First of all, hats off to all these members with great engineering skill sets, posting here. Really nice work. Myself being a somewhat newbie at all this stuff, I had to buy, try, wait 4 delivery, re-buy, retry, ... (the fun iterations), so it took longer as expected to do small overhaul on the KingSong S18 suspension. I just did the joints and replaced them, then added some PTFE dry spray. I went from this: (ali referral - furniture screws ) (seems like they are glued together) Replaced the set with this: (S TORX sleeve NUT M8-A2 - washer 16/10-A2 - PTFE washer <> bearings <> PTFE washer - washer A2 - TORX bolt A2) (A2 = stainless steel) Work: minimal intervention (one joint at a time, NO complete dismantling), some drilling and cutter stuff to get the right dimensions on washers / sleeve nut, then aligned the joints (playing with the air shock to align holes), and bolted it up again. A 15 min job for those that have experience ... Not me, see the iterations on getting the material... I expect the bearings to eat a little away inside the PTFE washers so that will work better over time And boy, what a difference: Out of the box I was able to lock the suspension at a certain height, just buy pushing it down by one foot, and it would stay in place. Now: the suspension is responsive as it should be. PS: I did not remove the metal blocks between the gliders. I foresee a future replacement of the Air shocks, since they wear out over time ...
