This author examined issues of failure of hydraulic components in a running Cat 311b machine and what should be done if they fail. Some good advices were given how to maintain your vehicle in its best condition.
Cat 311b Hydraulic valve spool is stuck or damaged
If your hydraulic control valve spool gets stuck or damaged, you may be able to solve the problem yourself. Follow these steps to unstick your valve spool:
1.Unscrew the four fasteners that secure the lid on the valve spool.
2.Use a pair of pliers to lift up and take out the plunger from the valve.
3.Examine if there is any damage or other problems with it, in case of damage, replace it; otherwise make an attempt at solving this issue by following these steps as well;
1.) Wipe away any dirt or rubbish that has accumulated on it over time.
2.) Put some light lubricant to its bearings (if available).
3.) Reinstalling the plunger on top of the valve and tightening screws holding it in place
Solenoid Cat 311b Hydraulic valve burst crisis
If you are experiencing a hydraulic problem with your Cat b, then you may be looking for answers. In this article, we will outline some of the common causes as well as solutions to a Cat b Hydraulic valve burst crisis.
The hydraulic system can be overtaxed when there is a Cat b Hydraulic valve burst crisis. As such, the valves may rupture causing floods or even loss of control over the machine.
One cause of a Cat b Hydraulic valve burst crisis is poor maintenance; others are excessive use and malfunctioning parts. Thus, if your machine is not functioning well it is important to identify what has caused that.
There are numerous ways out of Cat b Hydraulic valve burst crisis including worn or non-working parts replacement, modifications or repairs that would restore flow into the system and safety measures against flooding. It’s important that in case you are facing issues with your machine, look for help. You can get quick diagnosis and fixing by competent technicians.
Cat 311b Hydraulic spring rod is broken
Should the cat 311b hydraulic spring rod give you trouble, there are several things you can try.
The first is to change the spring rod. It is a relatively straightforward fix that would normally solve the issue.
You can also try fixing this by modifying the levels of pressure unless replacing the spring rod is possible. This usually fixes it if indeed the spring rod has a fault.
Air-conditioning control Cat 311b problems
Whenever your cat 311B air conditioner is experiencing problems, there are several things that you can do to troubleshoot and hopefully fix the problem with it. Some of the common problems with 311Bs include low air pressure; water getting into them and frozen coils.
Here are some tips on what to do if your cat 311 B is not cooling enough:
- Check the air pressure. Low air pressure may be attributed to a clogged filter or improperly installed valve stem. To check the air pressure, you will need a gauge that plugs into an electrical outlet in the unit. You should then turn on the AC unit and wait for ten minutes until there is normal operating pressure in the gauge. In case your AC unit was bought new or has been in use only for a short period of time, it may take up to twenty four hours for the gauge to reach normal operating pressure.
- Check whether water gets into its internal parts. If water leaks inside an AC unit, it might be due to either broken seals or fault valve stem. Stop all power supplies leading towards your AC unit, remove all sources of water (faucets, sprinklers etc) around it if you want to test whether there is any leakage of water going on inside an AC unit as well as if need be prevent it from happening again in future
Check and clean the hydraulic fluid return filter
Blocked filters are among the most common problems with cat Cat 311b hydraulic systems, which can lead to system failure and be difficult to rectify.
To confirm whether a filter is blocked, begin by checking the fluid level in the system. If it is low; this may imply that there is blockage in the filter. Initially, you have to completely clean off all junks that have settled on it. Take another container and put it underneath this filter then pour hydraulic liquid in it until debris are covered En sure you hold down button on this filter until all of the liquid has been used .Finally replace back the filters and fastening nuts tightly.
Check the hydraulic system pressure
The hydraulic system in a cat can create a lot of difficulty. When the pressure is either too low or too high, then the cat may not work properly.
To check the pressure in the hydraulic system, you will need to use a pressure gauge which is an important device that you should always have when working on a cat and it can also help troubleshoot other Hydraulic problems.
If the pressure in the hydraulic system is low, for instance, there could be a leak in your hoses. In that case you can replace this hose with another new one. If it’s high, one of your booster pumps might be faulty necessitating changeover. So you’ll require a fresh pump for that.
Check the engine speed and load
1.In case that the speed of the engine is low or the load is high, therefore hydraulic system can be loaded fully.
2.To verify this, first check out the oil level and pressure. Once these are ok, proceed to hydraulic fluid level checks.
3.The valves lines and pumps may have some problem if the hydraulic system is overloaded. It will most probably require re-adjustment of valves or pumps for it to go back in normal condition but in few cases some parts may have to be replaced in order to restore functionality of the entire hydraulic system.
Check for air in the hydraulic system
Air can infiltrate hydraulic systems, which is a common problem. As a result, the system will not work properly and this may cause an accident.
To avoid such a situation, check if there is air in your hydraulic system every time you start your vehicle. Test for leaks around the hydraulic system by pushing down on the brake pedal. If there are any, you must repair them before using the car again.
However, do not fret over a malfunctioned hydraulic system. Most of the times, there are simple remedies that are quite affordable. Simply consult an expert mechanic to deal with it immediately.

Check the bucket rollback pressure
The common hydraulic problem of cat b buckets is that the rollback pressure is not high enough and hence, it fails prematurely.
And so to fix this issue you had better examine the bucket rollback pressure. To accomplish this task, it will be necessary for you that you open an oil drain valve and have a look at the gauge pressure reading on the screen. The higher this value, the better. Whenever it is low, then obtain additional oil into the system or increase the oil reservoir pressure in order to boost up your rollback pressure.
Here are some solutions to common problems in your 311b
311b is a good service for reporting problems in your neighborhood. However, there are always some happening that will arise. Here are some common cat hydraulic problems and their solutions.
1.The pump has stopped working: This usually happens because the impeller is stuck. To fix this, take out the impeller and clean it using a mixture of soap and water. After cleaning, put it back together then try out the pump. If this does not work, you may have to buy another pump.
2.The sprayer has stopped working: It may be due to either clogging in the hose or motor failure. Usually, one can rectify this by cleaning entire sprayer inside as well as replacing any necessary pieces. If it doesn’t change anything in your case, then replace the whole sprayer.
3.The water is not coming out of the faucet: There might be many things that cause this but generally it is because of a broken water pressure regulator. You need to replace the regulator and tighten all connections accordingly to correct this issue.
4.The faucet is not turning on: Several things might lead to such a situation; however, mostly it results from a fractured water pressure regulator. In order to repair this malfunctioning faucet therefore you should remove & repair its defective parts.
5.The faucet is leaking: There could be a number of causes for that but mainly it’s caused by a broken water pressure regulator again. You must replace the regulator and also ensure all connections are tightened up properly for you to fix this problem
6.The water valve in the house is not working properly: You may have accidentally broke or removed when installing your new faucet.. In both cases however you will have to get new valves which you can test by turning on the tap with no attached soap dispenser.. If these don’t work, then an entire replacement unit would help now
