Q:A few days ago to a car POLO, accidentally remove the engine after the ring gear crankshaft behind the crank position sensor to get down, now the engine installed wouldn't burn, a question that is not the ring gear according to the previous position of the good, the master has repaired this a car I ha, very urgent!!!!!!!! Tell me in detail where it is there, the most important is the installation of the ring gear, the engine is 1.4 double cam shaft, 16 valve.

Crank angle and engine speed. The structure of the crankshaft position sensor is different according to the type of the vehicle, and can be divided into three major categories: magnetic pulse type, photoelectric type and Holzer type. It is usually mounted on the front of the crankshaft, on the front of the camshaft, on the flywheel, or in the distributor.

Q:What is the radial runout error of the ring gear?

The radial runout error of gear ring is a standard for gear post test. Generally speaking, it represents the difference of the teeth on the circumference of a gear. Popular point of view, with the detection of the beating of the outer circle almost, but the benchmark is on the teeth.

Q:How many teeth should the flywheel ring gear of the single speed diesel engine 158D12 teeth of the deceleration starter?

The flywheel has greater rotary inertia. The engine speed varies as the work done by each cylinder of the engine is discontinuous. When the engine speed increases, the kinetic energy of the flywheel energy storage to increase; when the engine speed is reduced, the kinetic energy of the flywheel is reduced, energy is released. The flywheel can be used to reduce speed fluctuations during engine operation.3, installed at the rear end of the engine crankshaft, with rotational inertia, it is the role of the engine energy stored, overcome the other parts of the resistance, so that the crankshaft rotation; through the clutch is installed on the flywheel, connect the engine and drive; joint and starter, so the engine starting. And it is the integration of crankshaft position sensor and speed sensor.

Q:Does the flywheel ring gear and the starting machine affect the vehicle?

Both sides of the gear ring have serious wear or tooth damage, and the repair can be repaired by surfacing when the replacement repair does not meet the requirement.Repair of flywheel working faceThe working surface of the flywheel or groove. The wear depth is more than 0.5mm, should be light grinding or after finishing mill. The thickness of the flywheel shall be no less than the new flywheel thickness 2mm after processing. The wave depth is no more than 0.5mm, allowing the existence of no more than two annular grooves, and deburring shall be eliminated.

Q:How to install the gear ring of the rear oil seal of Lang Yi crankshaft?

That way you can start?. The fire is a bit late. What else can you do?

Q:1115 how many teeth are used when the diesel engine is switched on?

Disassemble and inspect the suction and hold coils of the motor starter and their contacts

Q:Free car gear how to locate the school to start with the electric vehicle

If the gear ring basically does not have the school, with the wind welding, the ring heating, press the installation on the line

Q:How does the gear radial runout tolerance affect the gear drive?

The radial runout of the gear ring is caused by the misalignment between the center of the gear circle center and the center of the gear hole (or shaft) when the gear is machined (this is the main reason and the main influencing factor).

Q:Are gears and gear rings a kind of thing?

A cylindrical or conical gear is obtained when the teeth are machined on the outer surface of a cylinder or cone;The teeth are machined on the inner surface of the hole to obtain the gear ring;When the teeth are machined on the plane, the rack is obtained;

Q:Such as the title, consult an expert with us auto parts "flywheel and gear ring assembly" pressing method. At present there is no mature cold pressing process???Yes, press assembly, gear ring to match with the flywheel, not the gear ring fault analysis!? is there a cold pressing?

The common damage forms of engine crankshaft include shaft neck wear, crack, burn, bend or break.Inspection methods are given, such as repair dimension method, surfacing welding, arc spraying, brush plating and manual arc welding. The cause of the starter and the flywheel gear meshing. The ring gear and the starter gear will strike when starting the engine, causing tooth damage or side wear of the tooth. If the tooth is damaged or worn more than three times, the starter gear is difficult to mesh with the ring teeth...
