How To Repair A Hydraulic Floor Jack That Won't Stay Up I Don't Jack Up
Definition and its Usage:
Floor jack is normally known every bit the tool for lifting vehicles similar cars in order to change a tire or the car'southward undercarriage. It is used to elevator vehicles from i side from the basis and with the apply of floor jack nosotros can do this easily as floor jacks apply hydraulics. Floor jacks are easy and safe to apply if we used them according to the specifications of manufacturers. In guild to employ a jack, we have to identify them on the ground. Jacks are available in a diverseness of sizes and they lift weight according to their size.
Beneath is the flooring jack parts diagram, labeled with its parts name:
Maintenance Tips
Some of the tips I remember we demand to follow in order to proceed the floor jack working properly:
- When you store the jack y'all need to make sure that the piston and the pump are pull in and you should shop jack on its base of operations not on its side in order to avert leakage, these things enable the jack to piece of work efficiently next time whenever we need information technology.
- As we put our floor jack in a garage when information technology is not in use so it may be possible that it covers with dust which can crusade a problem so always cover the jack when not in utilize and you should non store the jack in the place where moisture comes in considering it can damage metal parts.
- You should inspect the jack before every time you lot need it, like cheque for cracking or rust on the casing of jack and check for the leakage by looking at the basis.
- Once you lot have used the jack clean it by wiping out the metal parts earlier storing it, it keeps the jack abroad from grit and always bank check the seal to avoid leakage. If you notice some issue first fix it and then store the jack.
- You should change the jack'due south oil time to time and also bleed out the air if you observe that the jack is not running smoothly because trapped air can cause damage.
- You should check the level of oil and add some oil if the rod is not moving smoothly but keep in mind that do not add together oil beyond the make full line or practice not overfill.
Common Problems and Their Solutions
These are some common problems I am describing below which we face in our daily usage of jack and I have also described how the floor jack troubleshooting can be done past identifying underlying reasons for issues.
Problem: Jack Won't Lift a Weight
Problem'due south definition: it means that the flooring jack is non lifting the vehicle up as information technology was built to use for, or we can say that the jack is not holding the pressure to lift the vehicle up for changing a tire or for doing anything else.
Solution:
In guild to resolve the problem i.e. the jack is not lifting a weight, the following could be the underlying issues.
Don't overload the jack
Brand certain that you are not overloading the jack which means that practice non endeavor to lift the vehicle which weighs more than than the chapters the jack has. So if your jack is not lifting the vehicle up start you need to bank check the capacity of the jack. Some of the jacks take features for safe due to which jack stops working when it is forced to elevator the vehicle more than than its chapters. This can be the reason of your jack'southward failure. So you need to first check the weight of a vehicle which is written on the motive force's door pillar. Light trucks and passenger vehicles can be lifted past the jack whose weight is 2 to 3 tons.
Check the level of hydraulic oil
If your jack is non lifting weight bank check the level of oil because both, the low level of oil and oil across the fill line or overfilling of oil can cause damage and prevent the jack from lifting weight i.e. decrease its chapters of lifting weight and lower its capability.
If you have less oil than I recommend to refill the oil in the jack and use oil of some high quality rather than the ordinary oil because it can damage the parts of jack, and if the oil level is exceeded from the fill line then you should drain the extra oil from the jack. If this is the reason for your jack's failure than subsequently checking oil level jack will be able to hold pressure.
Remove Air From Jack
Sometimes air gets trapped in the jack which prevents the jack from lifting up the weight then if you are facing a jack failure endeavour the procedure of bleeding to remove the air from the jack. In this procedure, yous demand to remove the screw of oil filler and then place the jack's release valve in a position such that it is anti-clockwise w.r.t the handle. The next you demand to exercise is pumping and screwing the handle as many times such that the air removed from the jack and information technology starts working properly.
Check The Release Valve
Afterwards the placing the jack on the ground properly, and pumped the handle merely still your jack is not lifting up the weight and then you need to check the tightness of the release valve such that whether information technology is tightened or not because if it loosens then the jack volition not piece of work. Past doing this you can resolve the trouble.
Do lubrication
Lubrication means to use some oil to all the moving parts of the jack to remove friction and in guild to keep them away from rust which tin cause damage to the parts and it is the about important thing to practise to go on the jack working. Then if your jack is not lifting weight try to apply some lubricating oil.
Audit the entire jack
After doing all the to a higher place things described above and still your jack is not able to lift the weight then it means information technology needs something else such that, check the casing of the floor jack may be information technology is ruined or cracked, check for oil leakage. Do an inspection of ram in both positions such that by pulling it in and out. These could be the reasons for your jack failure.
Problem: Floor Jack Leaks Oil
Problem Definition: means that the oil reservoir or chamber located in the floor jack starts leaking oil due to normal wear and tear.
Solution:
In lodge to resolve the above trouble, I recommend to replace the O-rings in the floor jack, the process of replacing requires the post-obit steps to follow:
1. Audit the Jack:
First, y'all accept to place the jack on the piece of work surface and inspect the point of leakage in the oil chamber, as Jack is heavy in weight and then make sure that the piece of work surface is potent plenty.
2. Release the Valve Screw:
In social club to replace the O-rings, we need to loosen the valve screw which is used for raising and lowering the jack you can loosen this spiral by turning it in a counterclockwise management with the jack handle.
3. Stand Flooring Jack and Drain the Fluid:
Once you take removed the valve spiral stand the floor jack on it is end such that the screw is pointing towards the ceiling, then fix the jack with clamps and so that it does move from its place. When the fluid leaks from the floor jack there is a chance that some wreckages remain in the fluid, set up the drain pan and drain out all the fluid from the hole of valve screw and then put the jack back upward to its position.
iv. Place New O-Band:
In order to stop leakage, you need to supervene upon the O-ring which is the reason of leakage when it becomes faulty, the O-ring is on the valve screw you can remove it easily with the screwdriver afterward removing clean the screw with the rag and and so gear up a new O-ring.
5. Refill Jack:
At present after replacing fill up the jack with the premium fluid recommended by your manufacturer, put the funnel on the pigsty of screw valve and pour fluid until it reaches the fill line, exercise not overfill the fluid.
vi. Place the Valve Screw:
After replacing the O-ring and filling up the jack with the fluid place the valve screw again and tightens information technology in a counter clockwise direction and then check the jack for the leakage by raising and lowering the weight using the valve screw.
Problem: Overload Valve Was Accidentally Turned
Problem Definition: Overload valve is a safety feature for the floor jack which has the warning "don't open" and then if it is turned on in incorrect management it causes harm.
Solution:
The overload valve feature prevents the jack from working if it forced to elevator the weight more than its capacity. If the overload valve is turned by you accidentally then I recommend seeking help from the hydraulic jack experts because turning it on in the wrong direction changes the tension of leap and every bit a issue there volition be a change in the functionality of jack.
Problem: Wheels did Non Roll Properly
Solution:
If the wheels of the floor jack is not rolling properly then I recommend yous to employ some lubricating oil on the wheels to reduce friction. This status occurs when you lot shop the jack after usage without wiping out the dust and when y'all store it in a identify where moisture comes in due to which the wheels becomes rusted and does not roll properly. Make sure that the oil you are using for the lubrication should exist a premium one, avoid using the ordinary oil because it tin can damage the metal of the wheels.
Problem: Cracking, Angle or Breaking of a Floor Jack
Solution:
If you detect that the case or frame of the jack is croaky, aptitude or cleaved then y'all should finish using the jack because it is not rubber to employ it and you should replace it with a new one. The jack's stability depends on the frame of the jack, if you notice that the frame of jack is angle than it ways it is not holding the vehicles pressure, and it would be a adventure to apply jack after facing this condition. If there is only a scratch on the frame so it is not a serious trouble, only a jack with bent frame must exist replaced with a new one, do not try to gear up it.
Trouble: Milky or Foamy Oil Leakage
Solution:
This problem occurs when the h2o or air mix upwardly with the oil, this happens when we practice non wipe the dust with a rag from the bleed plug. Then, to resolve this problem we demand to change the oil or refill in the oil reservoir. To refill the oil, follow the process:
- First, locate the bleed plug on your jack, it may be nether the tool tray or on the housing depends on your model of jack.
- Clean the drain plug from the rag to wipe out the dirt or grease.
- Then open the plug of the drain with a wrench.
- Place the drain pan and position the jack such that all the oil drains out of the drain plug hole.
- Put the funnel on the drain plug pigsty and pour hydraulic oil into the oil reservoir make sure the oil is premium recommended past your manufacturer and pour the oil in such a way that dirt particles or other materials do not fall into the oil reservoir.
- Remove the release valve and pump the handle several times in order to bleed out the air from the jack then put the release valve into its position.
Close the drain plug and wipe off any extra oil dripped during the process.
