[DIY] Shock absorber nitrogen charging station - build and test

[@laosgpsmapmidnitemapper9411]

Brilliant a bicycle shock pump with gauge and No Loss fitting! Nitrogen for motocross Super cross - Compressor air for Dual Sport and trail riding> No need for crazy high shock pressure unless you are doing big Jumps, the Shock pressure is to make sure no air enters the seal during rebound ( like your forks do) Another great video > Cheers and Thanks

[@DawidMartasMotoAdventures]

For many years I've used normal air in my AT750 without any problems. To pump the shock absorber I was using MTB shock absorber pump :) Now, to make it a little more professional I made this charging station. Sometimes I rebuild shock absorbers for customers and charging station should be first investment :)

[@plllot9713]

it's not about the pressure. it's the moisture in the air you're pumping in which might cause corrosion to metal parts.

[@laosgpsmapmidnitemapper9411]

@@plllot9713 the gases are in a sealed bladder and cannot cause damage from corrosion

Very good job!

Looks very professional👍

can u explain second small tank?? is it so u load only 15 bars?

[@marcellomagagna3018]

Very very nice! Great work!

[@TheSponge945]

Anyway you got a material list combined of all the fittings/tees etc?

[@burtomoto2000]

hi mate really good video.! Where did you get your fittings? and do you have the various sizes? Im finding it hard tracking the parts down (I have the regulator, bottle and suspension pump)

[@nwpacificg-mail5820]

Hello, Where can I buy all this hardware what you used? Pressure regulator and the rest…

[@DawidMartasMotoAdventures]

Hi! Pressure regulator is from welder shop. Hose, valve, connectors from air conditioning shop. Pump from bike shop. All bought online :)

[@benko989]

Great job! 👍 It looks very nice! Can you please tell me which sizes are those SAE adapters? T-piece is 3/8in?

[@DawidMartasMotoAdventures]

Hi! Those are 1/4 SAE. As far as I remember T-piece is 2x SAE and one metric thread for gauge. Those adapters are common in air conditioning stores.

[@benko989]

@@DawidMartasMotoAdventures Thanks man! You are awesome! 👍 It's hard to find such shops here in Austria and track those fittings, but thanks to you I managed to order everything from Amazon and soon I'll have my own Nitrogen charging station 😎👍

[@DawidMartasMotoAdventures]

@@benko989 The biggest problem is with the types and imperial thread sizes :D In Europe it is more simple :D

[@Pushyhog]

you should link all your parts below in thumbnail.

[@fabioschiavitti7706]

Hi, can you please tell me where you can buy the chuck from bicycle shock absorber you used in the video? Or what model is he ... I would like to find just that model ... Thanks

[@DawidMartasMotoAdventures]

Hi! It is Chinese Beto pump. Google: "Beto Shock Pump MTB 400 psi"

WHAT SIZE BARB END WENT INTO THE BICYCLE PUMP

[@plllot9713]

zdaje sobie sprawe, ze to niewielki szczegol, ale czy nie lepiej byloby najpierw puscic lekko azot na otwartym tym bezstratnym zaworku zeby pozbyc sie powietrza z przewodu i dokrecic zaworek dopiero wtedy. dzieki temu unikasz wpompowywania malej ilosci powietrza. ten cylinder tuz przed wejsciem do amorka to jest osuszacz? orientujesz sie moze czy zaklady napelniajace klimatyzacje bylyby w stanie mi skutecznie napompowac amorek, oni chyba maja odpowiednie przylacza a i azot powinni miec. ostatnio pomyslalem, ze warto byloby zmienic olej w tylnym amorze i kombinuje jak tu go pozniej nabic :)

[@rogerjones3504]

What was the size of the pump tube bore

[@an3880]

You made some investments and it sure is very professional but why not use a small pump like for MTBs and use air pressure? It's done in seconds.

[@DawidMartasMotoAdventures]

Hi! I used hand MTB pump for a long time :D The biggest problem is with the moisture in the air - there is no big difference between "dry air" and clean nitrogen. Anyway I think normal rider will never see difference between air and clean nitrogen.

[@brandonfontaine285]

same steps for a needle valve?

[@Alexandru960]

Hello, what is the purity of nitrogen?

[@DawidMartasMotoAdventures]

Nitrogen purity is more or equal 99,99%

[@HaNguyen-ip7ti]

How much full combo

[@DawidMartasMotoAdventures]

I think it was below 200Eur in total (gas bottle, regulator, hose, adapters, gauge, no loss chuck)

[@jorgezambrano3782]

don't forget to purge the hoses so that all that enters is nitrogen

[@richardhayter3919]

Thats a very good point, I will store that in the memory bank for future use 👍🏼

[@PH_INFO_101]

WHY? I think a better question would be "why do you need to refill the shock? If the shock has a defective pressure seal what good does it do to re-pressurize it, only to have it leak out in a few hours.
