Kobalt concrete mixer motor troubleshooting

Another common problem is something is holding the tub barrel and keeping it from spinning. Take it off and take it down to a parts store to replace it. The most common cause is the belt that connects to the output pulley on the engineвЂ™s crankshaft has either broken, stretched, or otherwise loosened. Typically, there are only going to be two causes for a tub that wonвЂ™t rotate. The rotating action of the tub and the blades inside provide the mixing action needed for proper mixing of the concrete. With a powered concrete mixer, concrete mix, sand, and water are poured into a rotating tub with mixing bladders inside. If the battery is fully charged, you will need to have the starter and solenoid tested. If the engine doesnвЂ™t turn when you turn the key, charge the battery and try again. If the mixer is key-operated, then it has a battery. If this doesnвЂ™t help, youвЂ™ll need a book to further disassemble the magneto assembly. Remove the three to five screws holding the magneto cover and remove any obstructions. This is usually caused by something contaminating the bearings or blocking the cooling blades against the housing cover. If the engine is started by a pull cord and that pull cord wonвЂ™t budge, then the magneto is frozen.

If either of these is the case, you will need to purchase a repair manual for the particular engine that powers your concrete mixer for the detailed step-by-step instructions for magneto troubleshooting and replacement. If you see no spark, then the magneto is either bad or needs replacement. Hold the handle of the screwdriver with the screwdriver blade very close, but not touching, a metal piece of the engine and pull the cord or turn the key. If the spark plug isnвЂ™t the problem, insert a #2 Phillips screwdriver into the spark plug boot until it makes contact with the electrode inside. To determine if a fouled spark plug is the culprit, use a (usually)13/16 socket and a ratchet to remove to spark plug and verify that there is a gap between the center electrode and the plug body.
