Where is the crankshaft positioning hole of the Roewe 550 located?
2 Answers
The crankshaft positioning hole of the Roewe 550 is located next to the crankshaft pulley of the sensor. The crankshaft is an important component of the engine, which bears the force transmitted by the connecting rod and converts it into torque, outputting it through the crankshaft to drive the engine's accessories. The Roewe 550 is a compact 4-door 5-seater sedan with body dimensions of 4648 mm in length, 1827 mm in width, 1483 mm in height, and a wheelbase of 2705 mm. The Roewe 550 is equipped with a 1.8L naturally aspirated engine and a 5-speed manual transmission, with a maximum power of 98 kW at 6000 rpm, a maximum torque of 170 Nm at 4800 rpm. Its front suspension uses a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension.
The crankshaft positioning hole of the Roewe 550 is generally located in the rear area of the engine, near the flywheel or transmission connection. As someone who frequently handles this model, I believe that in actual operation, some peripheral components need to be removed first, such as the transmission cover, to reveal a standard small hole, approximately 8mm in diameter. It is primarily used to lock the crankshaft position during maintenance, such as when replacing the timing belt. A special tool must be inserted into this hole to secure the crankshaft and prevent it from rotating. The location isn't particularly hard to find, but the depth can be a bit challenging. You'll need to use a light to inspect it carefully to avoid accidentally touching other components. The design of the Roewe 550 is similar to mainstream domestic vehicles, with the hole positioned on the engine's rear flange, commonly found in gasoline engine layouts. If you're unfamiliar with the structure, I recommend working in a quiet environment and taking your time to avoid mistakes, as incorrect positioning can lead to timing misalignment during reassembly, affecting performance. Safety during maintenance is crucial, so disconnect the battery before starting to reduce risks. In summary, based on my experience, this is a fundamental maintenance point, and learning its location can be of long-term benefit to car owners.
