Why Won’t My Cement Mixer Won’t Start?

Why your cement mixer won’t start?

Your cement mixer won’t start because of a faulty capacitor that isn’t functioning properly or a bad switch. Old oil that has remained in your cement mixer for too long or a broken (stretched or snapped) belt that connects to the pulley is another reason your cement mixer won’t start.

 

 

Faulty capacitor

You have a faulty capacitor if the cement mixer won’t start when you try to use it. To ensure this is the case, depress the start button while turning the drum by hand. This acts as a model for the function the capacitor is designed to fulfill. To reiterate, this is an easy problem to solve, and there are hundreds of capacitors in store to get your system back up and running as quickly as possible.

 

Bad switch

If, after manually rotating the drum, the machine still does not start up, this may indicate an issue with the start switch. It is quite easy and inexpensive to replace the switch, so you might want to give that a shot before messing around with components that are more costly and difficult to work with.

 

Snapped belt

Although it might not be immediately visible, a broken belt is one of the most prevalent problems of your cement mixer not starting. This is because of the frequent use, which has resulted in the belts becoming worn down. It is usually a good idea to have a couple of spare belts in case you get caught in a jam! On top of that, it is one of the easiest to recognize on these machines, as the motor can be turned on even when the drum is not turning.

 

Old oil

When you use oil in your cement mixer, it will become bad for the machine. This won’t allow it to supply oil to the mixer, making it not start. Sometimes, if your cement mixer has been idle for too long, it might not start when you want to use it. All you need to do is change the oil and remember to clean the tank before pouring the new oil.

 

How to fix a cement mixer that won’t start?

You can fix a cement mixer that won’t start by performing a maintenance procedure on your cement mixer, replacing your belt, and changing the old oil.

 

Maintenance procedure

Before using your mixer, you must familiarize yourself with the operation and maintenance instructions that came packaged with the mixer. Check these steps below to maintain your cement mixer.

 

1. Make sure the mixer is empty before starting.
2. Check to see that the floor and walls of the mixer are clear of any waste concrete. If required, clear away the buildup.
3. You should carry out a high-pressure wash if production is halted for an extended period.
4. At the end of each day’s operations, use a high-pressure washer and wand to thoroughly clean the mixer.
5. Verify that the discharge chute has been cleaned as well.
6. The inspection panel on the base of the weigh hopper ensures that the cement weighs hopper discharge valve is free of any accumulation.
7. Use a hammer with a plastic head. Do not use metal hammers to clear any buildup that may have occurred on mixer arms, mixing blades, scraper blades, and wall and floor tiles. These objects are made of cast iron, which makes them brittle.
8. Check to see that there is no accumulation in the door seal track.
9. Finally, ensure all your cement mixer parts are in good shape.

 

The cement mixer service and maintenance suggestions provided here can differ from the guidelines of your particular model. Always make sure you follow the steps provided by the manufacturer.

 

Replacing the belt

A defective belt can make your cement mixer unable to start. If it’s old already, you need to replace it with a new one. Follow our guide below to fix your belt.

 

1. Before you get started, make sure the engine is turned off by pressing the button on the engine-stop switch.
2. To remove the cowl, unlatch the three rubber straps holding it in place.
3. Swing the cowl up until it firmly rests on the frame, and then fasten it there.
4. To stop fuel flow to the engine, slide the lever that controls the fuel cutoff to the left.
5. Get a hold of the plastic housing located at the end of the spark plug wire.
6. Pull strongly in the other direction to detach the wire from the spark plug.
7. Take off the plate covering the engine.
8. To remove the engine plate from the gadget, slide it up and out of the device.
9. To remove the four bolts attaching the engine to the frame, you will need a wrench with a 3/4-inch opening.
10. To take the belts off and put them back on, you won’t need to completely remove these bolts; just loosen them just enough to generate some slack.
11. If you replace the belts, you can cut the old ones to get them off the vehicle.
12. Pull the belts off the pulleys by sliding them off in the opposite direction.
13. If you are having problems removing the belts, loosen the four engine bolts, so there is more room for movement.

 

Replacing the oil

Old oil can be why your cement mixer won’t start and can spoil your machine generally. Follow these steps to change your oil.

1. Put the mixer in a standing position and place a bowl under it
2. Pull the mixer down and start unscrewing the bolt to the oil tank until oil starts coming out inside the bowl.
3. Lower the mixer down for it to be fully drained
4. After draining, replace the oil with the new oil. The type of oil will depend on your model.
5. Tighten the oil tank back to 40nm

 

Why does your cement mixer keep stopping?

Your cement mixer keeps stopping because of a loose connection from the plug that cuts out your mixer’s power or a flimsy plastic fan that won’t roll as expected. A defective cement mixer that is too weak to spin is another reason your cement mixer keeps stopping.

 

Broken switch

The switch can go wrong after starting the machine. If you have tried the mixer by turning the drum, but it still keeps stopping, it is possible that the switch is damaged or is not functioning as it should be. This shows why your mixer can stop working after it has started operation.

 

Flimsy Fan

Your cement mixer can suddenly stop after running for a time. This could be because the fan is faulty or because part of the blades is missing, resulting in the motor not being cooled adequately and causing it to overheat after only a few minutes of usage. Fortunately, replacing a fan is a simple and speedy process.

 

Old cement mixer

Every machine gets old at some point in time. If your cement mixer is already old, it might stop working after a few minutes of operation. This shows you need a new cement mixer because if you change a part, another part might become faulty.

 

Carbon Brushes

Because there are so many moving parts, something will inevitably go wrong. The carbon brushes are one component of your power tool that has the potential to malfunction, and to know when it is time to replace them; you need to be aware that they are the source of the issues with your power tool. If the cement stops while it is being used, this is the last indication that the carbon brushes need to be replaced. This is a glaring indication that they have completely lost their substance.

 

How to fix a cement mixer that keeps stopping?

You can fix your cement mixer that keeps stopping by replacing the carbon brushes and fixing the magneto.

Replacing carbon brushes

Your carbon brushes need to be checked and changed if your cement mixer keeps stopping. Here is a guide to replacing your carbon brushes.

1. If the motor worked before you removed the brushes, it is quite likely they were not fitted correctly.
2. Take off the brushes, and then using a torch, examine inside the holder that they are stored on the mixer.
3. At the very bottom, a tab may be pulled out. If the brush is placed incorrectly, this tab will prevent it from touching the motor’s armature.
4. You only need to rotate the brush so that the angled side is aligned with the tab, and you should be good to go.
5. In addition, if you are installing the original brushes, utilize the wear markings to identify the side of the brush that it was removed from.

 

It is not a good idea to keep worn carbon brushes inside your cement mixer for an extended period because doing so can cause damage to it. Therefore, it is important to keep an eye out for the clear symptoms that the carbon brushes need to be replaced, such as power tools that operate poorly, foul odors, and unstable operations.

 

Fixing your magneto

Your magneto can be frozen, making the pull cord not budge. This will make your cement mixer keep stopping. Follow our guide to fixing your magneto.

1. Take out the three to five screws that keep the magneto cover in place, then remove any impediments in the way.
2. If this does not help, you must consult a book to continue disassembling the magneto assembly.
3. If the mixer is activated using a key, it possesses a battery. If turning the key does not cause the engine to turn, you must charge the battery before trying again.
4. You will need to check the starter and solenoid to see if the battery is fully charged.

Why your Belle cement mixer won’t start?

The reason your Belle cement mixer won’t start is because of some missing blades that make the machine not cool properly or a broken fan that halts the engine while working.

1. Make a connection between the first terminal of a resistor and the positive terminal of a tiny hobby motor.
2. Make a connection between the first terminal of the switch and the negative terminal of the capacitor using a single-pole, single-throw switch.
3. Turn on the switch.
4. Pull the plug on the switch.
5. Try turning the drum in the direction it should turn while hitting the start button.

This is a straightforward method that can help you figure out what the issue is quickly and easily. If the mixer turns on at this point, it will be clear that the capacitor is no longer functioning properly and will need to be replaced.
