Precautions for Engine Installation
1 Answers
Precautions for engine installation are as follows: 1. Maintain a clean environment, preferably with a separate overhaul room; assembly is best performed by 1 to 2 people, with one person taking the lead to avoid forgetting installations or torque tightening due to too many people. 2. Piston installation direction: Generally, pistons have markings, such as small arrows pointing forward or dots on B-series engines. Do not analyze the valve grooves on the piston; the larger groove does not necessarily align with the intake valve. 3. Do not install valve springs upside down: Wuling uses unequal-pitch coil springs, which have a specific installation direction. Generally, the side with yellow markings faces upward. If the markings are unclear over time, remember to place the denser part of the spring downward. 4. Camshaft bearing cap bolts are prone to stripping: The camshaft caps on Wuling B-series engines are made of aluminum alloy and secured with two bolts. Repeated disassembly or excessive force can cause thread stripping. Pay attention here; the standard torque is 12 Nm. 5. Do not mix up bolt types: Be careful not to confuse bolts during installation, as some bolts may have similar lengths and sizes but different thread pitches. Specifically, do not mix up the No. 14 bolts for the Wuling B-series engine manifold with those for the flywheel plate, as their thread pitches differ.
