How to install the timing chain on Roewe 350?
2 Answers
Roewe 350 timing chain installation method is as follows: 1. There is a small hole blocked by a white plastic plug near the lower right of the engine transmission exhaust manifold. 2. Remove the plug and insert an L-shaped iron rod of similar size to the hole, which should just pass through a hole on the flywheel (this appears when the four pistons are parallel). 3. Remove the transmission, and there is a hole on each camshaft (between cylinders 2 and 3). 4. After aligning the hole on the flywheel with the hole on the engine, ensure the two holes are vertical. 5. Insert parallel into the two holes on the camshaft to ensure the camshaft holes are relatively upward and parallel. 6. Then tighten the two previously loosened cam gears. Before this, pre-tighten the chain and the large pulley.
As a veteran mechanic with over a decade of experience, installing the timing chain on a Roewe 350 is a highly technical task that demands precision. First, the vehicle must be lifted, and the timing cover along with the old chain removed. The critical step involves aligning the marks on both the crankshaft and camshaft, typically secured with locating pins to ensure proper chain tension. When fitting the new chain, use a specialized tensioning tool to achieve optimal tightness, then double-check the alignment marks after tightening the fixing screws. The Roewe's engine design is unique, with chains and guides prone to wear, making regular inspections essential. Incorrect installation can lead to engine failure or internal component damage, significantly increasing repair costs. It's advisable to have the original factory manual on hand, ensure all tools are ready, and wear anti-slip gloves during the process.
