How to correctly align the camshaft signal disc on the Roewe 350?
3 Answers
The correct position of the camshaft signal disc on the Roewe 350 is on the gears of both camshafts, with one on each. Aligning them together ensures the correct position. Below is an introduction about the Roewe 350: Introduction: The Roewe 350 is a compact sedan positioned in the A-segment market, launched by SAIC Motor following the Roewe 750 and Roewe 550. It is also the first Roewe family car to incorporate 3G technology. Interior: The interior of the Roewe 350 follows the family's T-shaped design style, though it forgoes excessive embellishments in favor of a more straightforward approach to create a sporty feel. The use of dual-tone interiors reflects a home-oriented design direction, while the wood grain trim in the center adds a touch of sophistication. The manufacturer also offers an optional black interior.
When I was working on the Roewe 350, I aligned the camshaft signal disc, which is quite important. I think it's best to start with the engine timing: first, rotate the crankshaft to the top dead center position to ensure the piston of the first cylinder is at its highest point. At the same time, check the marking points on the camshaft and make sure the small notch or arrow on the signal disc aligns with the corresponding scale line. The exact position for the Roewe 350 should be checked in the manual, but generally, when installing the signal disc onto the camshaft, it must align with the reference point; otherwise, the engine ignition will be disrupted. Once, I rushed the job and didn’t align it carefully, resulting in unstable idle speed, and I had to redo it. As for tools, having a timing tool or a manual turntable would make the job easier. Remember to disconnect the battery before starting to prevent short circuits, and test the RPM after alignment. If the signal disc is misaligned, it could lead to a spike in fuel consumption or sensor false alarms, so take your time to handle it carefully.
I'm the owner of a Roewe 350, and last year I tried to adjust the camshaft signal disc myself—what a hassle. I looked up Roewe's information online and learned that I needed to stop the engine and disconnect the power first. Then, I removed the front cover to locate the camshaft area. The reference point is usually a small bump or marking line on the signal disc. After rotating the crankshaft to the TDC position, I adjusted the signal disc bit by bit to align the marks on both sides; otherwise, the car would squeak when starting. At that time, I didn’t have the proper tools, so I used a ruler to help measure—it worked out, but I’d recommend having extra lighting tools handy, as it’s hard to see in dark areas. Once the signal disc was properly aligned, the engine ran much smoother and saved a lot of fuel. During regular maintenance, it’s a good idea to check the alignment marks to prevent potential issues.
