Refilling oil filled telescopic shock absorbers.
Вставка
- Опубліковано 22 сер 2024
- How I have been refilling shocks for 40 years and saving quite a bit of money. One small mistake regarding the oil drained out, I should have said that it started life as 10 grade but ends up at about 5 or less, which is why the shock becomes pretty useless. Replace with new 10 grade to get back to original, ot thicker, 20 or 30 for increased damping and less body lean on corners.
This is the voice of a man who enjoys a succulent Chinese meal.☺
Voice "Sean Connery"..... thank you Sir 🙏
Double 007 is retired now rebuilding shocks absorbers.
With that pleasant voice, you should be on a radio station, instead of repairing
shock absorbers.
I do not know that I liked more of your video, if your clear explanation, or your impeccable English accent.
Your voice really looks like Sean Connery's. Congratulations
I always grease up the end of my drill bit and have somebody hold my shopvac nozzle up to the drill hole to catch the swarf. I refill with ATF as it swells the seals and makes it last longer. The seals for the rod allow a thin film of oil to pump by and the shock will have less oil than new from the factory. I fill them up and remove the air and just top them off and never have a problem. I TIG weld a nut to the hole and use a screw with fiber washer to seal it for next time. I top mine off about once per year.
I agree, good practise.
Many shock absorbers are oil filled and then pressurized with nitrogen to keep the oil from aerating. Also, the best oil for a shock absorber is one that keeps viscosity in all temps. Otherwise you wind up with a shock that rides hard when it gets cold out.
Is it possible to inject nitrogen into an oil type shock absorber? Because in gas type absorber, nitrogen and oil are in different chamber, not mixed in one chamber
Great tutorial! The oil drained seems to be in great condition though.. just for sharing, I have friends that welded a nut over the hole so he can put a screw over to cap it and to make the next oil change job easier. :)
Yeah he did say the shock he’s using has good oil just that it’s the only one he has to demonstrate with
astroboy Chew what i was going to say
spared no expense the voice of Sean Connery
u used to work in a breakers yard and a colleague cut through a shock absorber with a stihl saw and it literally exploded. i was told by the owner that on certain cars it can be extremely dangerous but i guess this is just the oil filled ones as there is no pressure. gas ones can be anywhere from 100-300psi which could easily blow your hand apart - make sure they are oil!!!
Weak End Yes, thats why I state at the beginning - for oil only.
Thanks for sharing the video though :)
Thank you Mr. Bond.
You can put thicker oil in to make the shocks even harder. For race use.
Old worn out gas shock absorbers don't necessarily bounce back up either so a bit difficult to identify 100%
I did this when I was a kid of an old car we were not using anymore. I didn't remove the shocks from the car but just drilled and full them.
I did this some years ago but I drilled a 3/16 hole then just screwed a 10 short bolt in no problems with leaks u can probably still weld it or use a brake nipple for future refilling
Did this to a stock shock to an volvo 240. Went great! used 15/40 oil(alittle mix with 10/40 and liiittle old oil left in the shock). But, its rly "tardy" to pull out but when compressing it dosnt feel very stiff... Am gonna get another shockabsorber and compare, but it kinda feels "loose"... Anyhows, great vid! U should do more of these!
@General.E.Shady can you please specify exactly which oil to use? engine oil or hydraulic oil? I am repairing my truck shocks,,
@General.E.Shady thanks very much,,mate,,for taking your time,,good on you,,
Thank you
That is great what you demonstrated. But if you capture the welding part also, it would be a complete DIY procedure for any person working on shocks.
Thanks for your generous idea 👍
PERFECT DIY VIDEO !!!
I thought I was listening sean Connery the whole time LoL
Thank you for the video.
Interesting video. I never heard of anyone doing that before. You a cool accent, kind of sound like Sean Connery.
Theres always a bur when drilling what about the risk of swarf getting in the valves?
Shox don't affect body roll in corners, they will affect the momentary roll when the car attempts to move but will allow full body roll as the shock is weighted, there is no spring to support weight shift just a reduction in the speed of the roll. Shox are to dampen the resonance of the springs not hold a car up.
Right, now have a good laugh at me, I drive a 3 wheeler, a Reliant Robin, not a Robin Reliant, or a Robin for short, been looking at how to do the above, me shocks are around 30yrs old, dont leek, just a bit old, they are oil and not gas, so many thanks, I was thinking of putting a screw in nipple in hole instead of welding it, you lean some think new every day, when some think is brock nows a day, in stead of try to fix it, they get a new one, costing £100 or more, this way, 2hrs, may be £10 for oil, ps, well 20/50 engine oil work, that wot I put in me engine :)
Amazing 👍🏻
Wow .. what a brilliant hack. What kind oil used for commercial ... semi trucks shocks... ❤
Excellent technology
You should do audiobooks
Thanks a lot for the video but the question is… how to close the hole safe
Great voice
Ok people if you want know if its a gas shock ..wash it clean ..its written on it ....oil type arr not written ...if its a gas shock and the gas has escaped. It will feel just like the oil type when dead ...so wash it clean and search for the word GAS
Hi Hensen, Interesting video. I have some shocks on an old 2CV (I think they are just oil shocks) I will drain them and measure the oil that comes out but wondered roughly how much there should be in a shock so that when I drain them and see how much oil there is currently it might give me an idea as to whether they have leaked in the past and the seals are shot - so probably not worth refilling. Useful video, thank you. Chris
If its leaked past the seals it will be obvious. They usually take about half a cup full.
Read below. Many ways, but I weld it closed. You can use a plug or bung, up to you. But, I always use a blob of weld.
You should making money with your voice... Great job, thanks
thanks and you have a great voice
New KYB shocks go back to extend position by themself, but they still have oil in them.
You probably wont need to refill new ones for a long time.
Hensen1954 well, I just bought two that leaked oil, brand new out of the box🧐
Hi Hensen, I have new shocks that bounced about 4 times when stopping. do you think
fitting a heavier weight oil would slow the bounce down ? thanks
Yes, 100%. Use 20 grade to firm it up.
@@Hensen1954 Many Thanks.....
Keep on pumping it until all the oil comes out there we go lol
Halo Sir, nice video.
I just bought oil filled shock make "Amada Extreme" , comfort type. I think it is too soft for me. I would like to change the oil. What viscosity should I buy? I love speeding
20 grade.
Mantap
Is this Sean Connery talking?
Bond. James Bond.
British accent
Deki S I was thinking the same thing lol
Deki S Ya, Sean is broke so he's doing UA-cam videos for money. 🤦♂️
hey 007..i think they all bounce back regardless of being gas charged or not.
Nope.
I took my car (Dodge Neon 05) to a car repair shop to check the shock absorbers, and they offered me to repair them, because they were apparently locked. The struts with the shocks were dismantled, and the manager told me that he repaired them, changing the oil. He showed me that now they could be pressed down with a hand, and this didn't seem to me to be right.
They installed and I left the place. The result is that now the car is bouncing on the springs of the struts, they have no damping. Also I notice that the suspension is lower behind than it was before. The driving is unbearable, the car bounces on the springs with the minimum road bump.
When I asked the person in charge of repairing the shock absorbers if he had assembled them with a lot of pressure, he replied to me: "Since it's a small car I did not put too much pressure in the shock absorvers."
How is this possible? How can you regulate the shock absorber with much or little pressure? Pouring less oil?
He offered to increase the pressure on the shock absorbers again. What should they do? Increase the amount of oil? According to what I understood in your video, you have to pour the same amount of oil that comes out, no less, no more. Is that right?
I have to go back there next wednesday, I would really appreciate your advice.
Greetings. I looked at the Neon shocks / struts. They are only 71 dollars new for a pair, so very cheap. Anyway, back to yours. Something is very wrong. Yes, you must use the correct amount of oil. To make them stronger or softer, you change the thickness of the oil - and just a little bit thicker makes a huge difference. Try squirting water out of a syringe, then try treacle !! Nearly impossible. If the car bounces like you say, its bordering on very dangerous, as well as uncomfortable. The Neon is not a heavy car - about 2700 lbs - so for road use I would go for oil rated at straight 15 grade. However, I was not sure about the shocks being "locked " ?? Does that mean seized ?? The situation does not seem logical to me with the above information, that the repair shop told you.
+Hensen1954 Yes, the manager told me they were stucked or jammed. When you tried to push the car down in the rear corners they didn't move at all. Now I'm not sure if that's a valid test, at least with this car.
I am not moving the car too much until the problem solves. It is unbearable the bouncing. They told me to go tomorrow to fix it. What I want to know if they can restore the shocks increasing the pressure, specially the height, since I see that the suspension Is lower than before and that makes the springs to work in excess.
By the way, I appreciate your advice of buying a new pair of shocks, but I live in Venezuela, a country turned in a new Cuba, and shocks and all car parts are very expensive. I am doing this as a temporary solution.
So, my final question is: can be solved? Can they increase the pressure of the shocks pouring more oil assuming they didn't fill the shock with all of the oil it should contain? I got the feeling that the manager wanted to save in oil, because of the price he charged me. Thanks in advance for your answer.
OK, good luck.
Very informative but I have a problem that you havnt covered . My car is a Humber supersnipe and shock absorbers are not available but all the oil has leaked out of both of them , so how much oil should I use ? can I over fill the things ?
No point in refilling if they are leaking. You will have to get new ones. You will always find something to fit. Just measure the fully out and fully in length and get ones from something else. You could even get air shocks for a few extra quid.
James Bondish
Can I convert the gas shock to oil is there any tutorial video
You can change them for oil type.
the new oil you put in and all the hassle, a new shock absorber cost less lol
This is drastically cheaper, and what in new shocks dont exist for a vintage car .
PlaystationQUAD-Pro $100 a shock is cheap????
So, there is also some air inside or can you fill it to the brim with oil? Do you have to buy shock oil or can you use a certain grade engine oil? So any 30 grade? 5/30 10/30,, 0/30 any engine oil, etc?
Nice!
great video thanks
Amazing job.
One question:
When you put new oil, how do you remove the air bubbles?
Thanks
Hi there, i watched this video and tried to do this on a steering shock absorber.
The shock seemed to be a oil filled and not gas filled.
When i drilled the hole the oil sprayed a bit as i were drilling but nothing dramatic, so im pretty sure its a oil filled as if were a gas it should be a lot worse.
So, i then get a 30w oil and sent the shock so a guy could weld a nut over the hole so i can close it with a bolt, and when i want to refill again i just open it and close it again. Well this guy opened the hole a little more and there was a little rubber on the inside and when he was opening a bigger hole he also drilled that rubber, and i dont know if this is bad or not?? Why? When i get back with the shock i refilled it with the new oil, but i got a leak trough the weld beads.
I then filled the weld with epoxy jb weld. The problem is i kept getting air inside the shock when closed. I fill with oil and the shock makes a good motion(stiff) trough the travel, but when i close it and pump it it starts to make movement stop as air i sttopping the shock travel and getting soft...Do you have any ideas to fix this?
Thanks.
Maybe if you pump it more the air will be dislodged. I have never had a problem when I do the work as in the video.
Hensen1954 .
I believe the problem is with the plastic bag inside, its filled with air and works as air stop or a space filling as no gas is needed in that application. for example my plastic bag was pierced, so when the shock was compressing the oil was taking the space in the pierced plastic bag making the shock lock like air was still trapped inside. so here is a warning to you all ou there, do not pierce that plastic bag or you will throw a shock out. it is imposssible then to make the shock work without that.
i will try to get a hold of another one so i can try again.
bom dia vitor será que me pode ajudar no tópico que meti em cima?
obrigado
are you James? James bond Sean Connery?
Yes, but I only live once.
Henson, if you're still around, I have 1960's Honda M.C. shocks that I think the oil has gelled rather than thinned, I don't know that for a fact but I suspect that. I wonder if you have ever cleaned a non-rebuildable shock and gotten the old crud out and replaced the oil afterwards, and if so is there a way to determine how much oil to replace it with. Thanks for the video, I always wondered if there was a way to replace oil in shocks that don't leak.
I doubt it has gone to gell, with no oxygen. I think follow the video and see if its still liquid.
@@Hensen1954 I'll give it a try then. Thanks-
hey bro! nice video but i have a question! you ever tested repaired shocks on your car before? & in some other videos i saw other guys adding air to the shock after filling up with oil is that necessary ?
Jamie De Angelo Yes, I test for 40 years. You do not need to add air. OIL is OK.
ok bro thanks! ive been wanting to try this. i bought a pair of kyb gas shock and it rides like shit
You need someone holding ur camera lol
Okay, I will try this. I was wondering, if 30w motor oil is good for slalom races ? Nice vid btw
yes,
You can use just any engine oil? Also I have an oil shock and I can push it down with one finger and it wont come back up unless i pull it back up and it is hard to do. IS this shock no more good?
Kyle Sauve I
what about quick fitting for adding air pressure or nitrogen
How to fill the hole?
Damm,guy,(and galls,can't forget them!):here what you DO!!!!!! you braze a M8 nut over the hole,cut a M8 bolt short,and tighten it in there, WITH a COPPER washer; you DON'T weld up ,on that shtt ,after it's full of oil!!! (you could ,but you shd stand 30 ft away,lol).
You could do it that way. as already talked about in the previous comments below - about 2 or 3 years ago.
Question sir which oil is better engine oil or transmission oil
I use engine oil.
James Bond doing DIY.
Hi Hensen :-) i like your voice and the kind like you teach us :-D
Hensen...i hope you can help me..
I have a set of gas filled monotube "track" coilovers.
On the i-net i cant find the infos i need to rebuild them...thats why ì ask you.
They are disassambled...now i need to replace the O-rings and oil but i dont know how much and which oil because they were nearly empty when i opend it and i dont know how much pressure (nitrogen?)i should give them.
Please help :-(
kind regards Dave :-D
I wanted to know if you get the oil hot in that shot will it blow up? I am trying to figure out should I use a TIG Mig?
If you weld it with the hole facing up, the oil will be lower down, so it does not catch fire easily. However, sometimes, if you dont weld quickly, the gas catches fire, but it is nothing more than the flame from a match - no problem at all. They dont explode, lol.
@@Hensen1954 do you have any videos or anything so I can see how you actually weld it and how you did your B I want to make sure I do this right thank you so much.
MY SHOCK COMPRESSES VERY EASILY AND REBOUNDS MORE SLOWLY DOES THIS MEAN ITS BAD??
If it rebounds without you pulling on it - its gas filled.
great video i had a thought though. could you tap in a thread and install a bleed nipple so if you wanted to tow a trailer you could add a bit of extra oil and then when finished bleed some oil back out ? would adding a bit more oil solid up the shock or do you need a thicker grade?
+Bryan Foat Please read other comments, however, why add extra oil for towing. Do you put extra oil on your engine to drive up hills ??
because as soon as you put a caravan on any car it lowers the ass off the car even if the ball weight is low. going up a hill has nothing to do with it and i aint stupid i was just asking a question as atm i have air ride shocks that can be pumped up when towing but you would think if you could put oil shocks on it would be a more stable ride and less risk of an air line blowing and potentially causing an accident. my question is can you add more oil for more ride hight or would you just bleed the oil out and put a thicker grade oil in?
+Bryan Foat More oil or thicker oil does not change the ride height with this type of shock. Thicker oil makes a stiffer shock.
I tried tapping with 1/8” NPT (tapered pipe thread in US) it barely works as the shock wall is so thin. A plug and epoxy putty (quicksteel) will hold the plug and help it seal tho, which is a lot simpler than welding, albeit uglier. If you want more damping use thicker oil, not more oil, the shock should be full already as it is.
Is this a twin tube shock? Did you drill just through the outer tube or through both of them?
Yes, only drill through outer tube.
a few questions, does the hole have to be at the bottom ? since i will try this on an old shock absorber with a slight leak is it safe to add oil till half of the reserve tube assuming the pressure tube is fully filled ? if so, i plan to drill in the middle so if oil overflows then the reserve is half filled. how much pressure is there in the reserve cavity during operation, reason i ask is how i will seal the hole if i have no welding equipment. thanks!
Greetings, I drill at the bottom because the oil is there, and it does not interfere with the up and down movement of the dust cover / shroud. I think every shock I have done has had about half the amount in the oil can I use in the video, so I am guessing an eighth of a pint. You dont have to weld up the hole, you can tap and bolt or just use a rubber plug / cover, held in place with a sturdy jubilee clip. There is pressure in the inner chamber when the piston is in motion, but that is in comparison to the second chamber, not between the inside and outside of the shock. Experiment as you wish, you dont have to worry, its not filled with dynamite !!
Hensen1954 .
thanks for the prompt response. i will experiment on soldering a shrader valve and see if it works too if i pump in nitrogen or maybe just air. the reason i asked some of the questions is that i will have to install it in the car to see if it works well and it's the coil over type so not that easy to install/uninstall. thanks again.
john adams
was experimenting on this, and found out that if you put too much oil you won't be able to compress the piston rod all the way down to the bottom at least by hand. so i temporarily sealed the hole, rubber and jubilee clip is fine, and checked that the rod bottoms otherwise who knows where all that pressure would go,
Your voice sound like Dirt Rally 2 navigator.
Sorry, I have never repaired gas filled. I just buy new ones. Surely, they are not expensive on e bay ??
Good day someone can give me some tips?
How do I know the amount of oil that I will put on the bumper if it's frill?
I have 4 bumpers to carry and ruffles someone can tell me if there are valves for the same?
nice one
Hi Sir! I just wanna ask if this method can help wornout shock absorber back to its original pressure, as good as new one?
Yes, or even better.
Motor oil will suffice to refill the shock? 20w mono grade motor oil? or am looking for a specific type of oil? 20w50 multi grade? or something else? Thanks.
Yes, 20w mono is OK.

@Hensen1954 Great video, thanks for sharing. If your ever interested I am sure you could easily do some voice over work, you sound remarkably like one of my favorite actors, Hugh Laurie. I am sure you've heard that before. By the way check out "The Night Manager" if you haven't already, great mini series.
Cool. People usually say Sean Connory.
refilled but 10 or 15 hydraulic oil
10 will give you a good ride. 20 is better for fast road driving. Good luck.
i appreciate you've taken the effort
but fuck me! did you have any forethought about making this video?
Yes.
oil hydraulic? or 10w40 oil engine?
Engine oil, 10W or 20W or 30W. Up to you how strong you want the shock absorber to be.
Great ideas i will try my shocks and give you feedback.
I am trying this job foreign country
Fantastic - good luck. Tell us if it was OK ??
can engine oil be used or is it some other kind of oil
Engine oil is OK.

Arc welding is too fierce. Engine oil is OK.

how much pressure gas need in this?
There is no gas or pressure, only air.
tq sir
what about for 10w40 oil?
and does it has to be new oil or ot can be used one from motor changed before interval
Well, I only used straight oil of a given viscosity. But would never use old oil when its so cheap to get the3 good stuff.
that's what your wife said.
get a tripod please
shoqq
if trying this see first comment, weld nut over hole and cap with a bolt while no oil is in the shock. if you have a sealed steel pipe, fill it with oil and simultaneously seal it while heating it to several thousand degrees, what you are likely building is a pipe bomb....................
can you screw in a nipple instead of welding ?
No, read below reasons
so first i have to buy a welder !!!
MrDelvis007 Or borrow, or take to a mates whose got one, or use a rubber seal and jubilee clip.
Hey. Interesting. Where’s the part where you weld over the oil filled pipe and then drive down the road with it installed?
Lol
