2500lbs

@@pavelblaha5243 yes, filed it about one cm under edge and closed. I can't find ideal volume.

Agree. It is normal to pay 200 for rattling walking cane.

@@iamengineer9795 and I

From local Bosch service. Price around 70-80eur. It is battery lawnmower and part I bought is motor controller. I trying to repair old one but MOSFETs looks good, maybe Hall sensors, but it is ok is like repair something trapped in amber.

@@iamengineer9795 thank you so much

Where’s the video showing how to service it? Lol I just ordered one and it will arrive today. I saw one good video on disassembling and refilling the oil and read some bits and pieces and now have a basic idea how it works. I was mainly looking for something showing what effect mounting it with the rebound adjustment on the bottom. Can’t find anything official but I saw something saying it can be mounted at 70 degree angle, but it doesn’t specify if just doesn’t like being horizontal or if it doesn’t like being anything other that rebound on top +/- 70 degrees. If I understand it correctly, the air chamber and its expensive floating piston is replaced with a piece of closed cell foam that acts as the air chamber and never gets soggy. So to refill it you need to get all the air out except what air is inside that piece of foam, such that after its all tightened back up, the air in the foam will compress as the shock rod goes in, taking up more volume, and as the shock rod withdraws, the foam quickly expands back because the air is high pressure now. In theory if you can burp all the air out with the foam fully expanded while the rod is withdrawn, the main damping piston should stay totally submerged in oil and give designed compression damping and give the rebound damping you dialed in. I think the foam is the key to understanding this shock and how to service it. Everything else is basic seals and o-rings.

@@imho7250 I just add oil as you described. Some disassemble maybe later, I would not destroy slightly leaking shock.

@@iamengineer9795 , I don’t think you will destroy the shock by opening it. There are a few videos showing how to do it. I think the key to making that shock absorber work good for your application (horizontally mounted) is using the proper viscosity fork oil and getting all free air bubbles out, while allowing the air bubbles in that foam to remain sufficient for the shock rod’s volume as the shock is compressed. My shock is brand new, not yet leaking, and I’m still testing if it has adequate damping. My initial impression is that it has virtually no compression damping and to get barely acceptable rebound damping I have to close the rebound valve fully. This tells me that it needs higher viscosity oil to get the rebound adjustment ideal while the adjustment knob is about halfway between fully open and fully shut. In the videos I saw they didn’t show if it actually had any significant compression damping built in or not. Its quite possible the compression damping port is fully open so that the foam doesn’t just instantly compress fully. I have no idea because I didn’t take it apart yet and none of videos show the main piston fully disassembled.

It is inserted to handle by force, so if you use force to knock it out it should be fine. Until they don't used some glue too.

Yeah, very weak at the tang, where it goes into the guard. Not a good knife.

@@longrider42 we talking about 80eur knife. 400eur knives can break too. This one is designed for stabbing

@@longrider42 Have you seen the Cold Steel promotional videos, where they stab car doors and smash into concrete?! For all its worth, it looks to me like a VERY GOOD knife.

I have it with valve facing down. It is not recommended, but it leaking the same way as with valve up.

@@iamengineer9795 Thank you!

EXActly😅

​@@iamengineer9795i remove the silicone sponge then add the oil... Mine work just fine till now

​@@AggiGitoo-hm5qqthis is the reason why I bought this type. Repair possibility.

No, that's a battery-socket problem. Remove main cover (4 Torx T15 screws) and in the front replace the tiny spring (Bosch item number: F 016 L66 108.). When the spring gets worn out the vibration of the machine shakes out the battery from its place in 2 seconds. Try holding the battery firmly in place and if the machine doesn't stop then it's definitely the spring.

I will made better video soon. This was first attempt.

​@@iamengineer9795 Would oyu mind quickly explaining a bit here? I can't seem to find where to unscrew or open it thanks

@@iamengineer9795 I have fork oil but can't find a way to open it, thanks

​​@@DaStuntChannelunscrew it. The is a cap on piston side. Connection line about 1,5cm from top

It was not primary filming for sharing. Wire to brush was broken, just soldering it back.

Looks it like dropped?

Broken chip near the end of

Button tear off from Chinese PCB. First R , then ZL. Now R stop working, need to be replaced for new one. This PCB is one tragedy, bad designed. It is microswitches, it should be impossible to push towards it with force.

In fact, this one was my fault, because I tried how it holds at PCB, with little force and it popped off with copper layer. For many people this mean new motherboard because of design. Buttons should have separate board like on cell phone.

​@@iamengineer9795 I had a new 2ds XL but I dropped it once and the screen cracked

it change over time.

With tube

It was the same. Oil leaked out. This one was installed properly with valve pointing up. Mine with valves pointing down hold much better. Maybe this one was to soft spring.

@@iamengineer9795 it can be too soft. Exa tells 70 degee mounting. Iam going to buit custom rear suspension to techlife 5s with exa air, just looking parts for remote co2 controls to adjust suspension while driving

@@janiwallin482 main reason for this one was I thought it will be serviceable. But there isn't any seal kit 🥺

@@iamengineer9795 don't cry my friend 🤣🤣 , there is no original seal replacement but I took it apart ,measured everything and bought the seal topped up oil and the shock is like new 😀 below size of the seal Google: rotary shaft oil seal 10x18x5 Thank me later 😀

​@@kamillapaj87How do you open the oil catridge ?

Yes, they are good.

@@iamengineer9795 any videos of them mounted??

@@knotjustresin I will try make some today.

​@@knotjustresin th-cam.com/video/urp879iLE5g/w-d-xo.html

Zatial som nenašiel sadu tesnení. Ale dolievali sme olej.

@@iamengineer9795 do you think its okay to use normal oil seal like in car for crankshaft or camshaft ?

@@kamillapaj87 I don't think it will be simple O ring

@@kamillapaj87 use fork oil.

I can measure it for you.

@@iamengineer9795 Thanks! 🙏

@@jockethebastard 31mm inner, 45mm outer, 67mm length. 650lbs spring

@@iamengineer9795 thank you so much for doing this, unfortunately the springs are 8mm to wide.

I haven't idea. Most people around 100kg + use 2000lbs in front and 2500lbs rear. I riding stock red springs. They have maybe 1500.. nobody knows. Changing springs are expensive so I using stock with my 95kg

No..just some oil leaking

But springs is not damper. I using stock springs and dampers from exa 291R

Not recommend. It will be too high and probably hitting bar connecting both arm sides. Try pull out stock one and do some measuring.

@@murkosk5714 too high with your weight on it ? I think it will even out

@@murkosk5714 i fitted 150mm just now

I did not find any spare parts. But it can be opened and refill with oil.

I also dissamble and refill the shock with suspension oil but, after some days dont know how the oil in the chamber begins to leak from somewhere that I cannot figure out from where. I found this shock very poor reliability.

​​@@suw1837How exactly did you refill it and how to dissable it ?

​@@iamengineer9795Do you know how exactly it can be opened ?

​@@lifeamazing9203I have video somewhere. It need to unscrew.

China :D

Yes, it was pretty overloaded. But pair of them parallel.
