XinChai 4D27G31 Cylinder Head Cover 4D27G31-11100-3 — HELI/Baoli Forklift Diesel Engine OEM
This cylinder head cover (valve cover, part number 4D27G31-11100-3) is the OEM XinChai valve cover for the 4D27G31 diesel engine — a 2.7L 4-cylinder water-cooled diesel power unit used extensively in HELI CPCD30 and Baoli 3-ton diesel forklifts across China and global markets. The 4D27G31 is the successor platform to the Xinchai 490B, offering improved emissions compliance and higher power density while maintaining the same engine mounting pattern. The cylinder head cover on the 4D27G31 is a stamped steel component designed to seal the valvetrain assembly against dust, debris, and water ingress while containing the pressurized oil spray from the rocker arm lubrication system. Unlike automotive engines that use plastic or composite valve covers for weight savings, the 4D27G31 uses a steel cover for superior high-temperature resistance — forklift engine compartments routinely reach 80-100°C ambient temperatures during sustained operation in warehouses and yards.
This XinChai-brand cover is manufactured in Jiangsu, China with standard size specifications. Weight: 2 kg. 3-month warranty with video outgoing-inspection provided. Application covers tractor, loader, farm truck, and forklift — for repair, replacement, or modification. MOQ: 1 piece. The high-temperature resistant design is critical for diesel engines where sustained high-load operation (lifting rated capacity, climbing ramps) raises cylinder head temperatures significantly above normal road-vehicle levels. When replacing the valve cover, always use a new gasket — the 4D27G31 uses a formed rubber gasket with integrated sealing ribs that takes a permanent compression set after the first installation cycle. Apply a thin film of RTV silicone at the camshaft end cap junctions and the timing cover-to-cylinder head transition points. Torque the cover bolts in a cross-pattern to specification — the 4D27G31 cover has a specific bolt tightening sequence due to its length. Overtightening warps the cover flange and creates oil leaks that worsen over time as the thin steel cover expands and contracts at a different rate than the cast iron cylinder head.
