Standard setting is 1400 ± 100 RPM or 1500 ± 150 RPM . Spark Plug: Typically uses a D8TC plug. Primary Components & Assemblies
Start the engine and let it warm up to normal operating temperature (approx. 5–10 minutes of riding).
: There are several websites that specialize in hosting and selling service manuals for a wide range of engines and vehicles.
Always use a calibrated torque wrench during reassembly to avoid stripping threads in the aluminum casings. Thread Diameter Torque Specification Cylinder Head Nuts (M8) 28–32 N·m (20–23 ft-lbs) Cylinder Base Bolts 10–12 N·m (7–9 ft-lbs) Crankcase Bolts 10–14 N·m (7–10 ft-lbs) Flywheel Bolt 50–55 N·m (37–40 ft-lbs) Clutch Hub Nut 40–50 N·m (30–37 ft-lbs) Spark Plug 15–18 N·m (11–13 ft-lbs) 6. Troubleshooting Common Engine Issues Engine Hard to Start 162fmj Engine Service Manual
Frequent servicing ensures longevity for this air-cooled unit.
Because these engines are manufactured by a dozen different companies (Lifan, Zongshen, Loncin, Ducar, etc.), the is crucial—generic advice often leads to stripped threads, incorrect valve timing, or catastrophic failure.
Disassembly of the two-piece crankcase. The manual warns against prying the cases apart—they are sealed with anaerobic gasket maker (like Threebond 1184). You must use a rubber mallet and specialized pullers. Standard setting is 1400 ± 100 RPM or 1500 ± 150 RPM
Remove the alternator cover cap and rotate the engine to Top Dead Center (TDC) on the compression stroke.
In short, the 162FMJ is a 149.4cc (150cc), 4-stroke, single-cylinder, air-cooled, overhead valve (OHV) engine. It is a direct descendant of the Honda CG150 design.
She closed the tin pages, wiped a tear onto a copper cup, and began mixing the oil of three sorrows. 5–10 minutes of riding)
While this guide covers the core operating principles and maintenance, a full, vehicle-specific (often found under CG150 or Zongshen/Lifan manuals) will contain exact torque values, wire-color schematics for the ignition system, and detailed transmission teardowns.
