Daelim Cordi 50 Scooter Manual FSM (P/N SM49-0406-01E)

• Daelim Cordi factory service manual, publication code SM49-0406-01E - a 186-page PDF for the Cordi fitted with the SE50E air-cooled two-cycle engine; factory tables also identify Europe-only specification differences.
• Covers engine removal and installation, cylinder-head/cylinder/piston service, carbon removal, dimensional inspection, crankshaft and crankcase-bearing work, and final-drive transmission disassembly and assembly.
• Details the kick starter and continuously variable transmission, including drive-belt inspection, drive-face and weight-roller service, clutch-shoe replacement, driven-pulley bearing inspection, and clutch/driven-face assembly with the specified holding and compression tools.
• Includes carburetor removal, cleaning, float-level inspection, throttle-valve service, fuel-autocock and reed-valve checks, plus oil-pump inspection, adjustment, and bleeding for the separate-lubrication system.
• Provides front and rear wheel service, tubeless-tire procedures, front-fork and steering-stem work, rear-cushion disassembly, rear drum-brake service, and front hydraulic brake bleeding, caliper, pad, disk, and master-cylinder repair.
• Traces the MF battery and charging circuit, A.C. generator, regulator/rectifier, CDI ignition, pulse generator, starter motor and relay, lights, meter, and switches through system tests, location drawings, continuity data, troubleshooting charts, and a full-color wiring diagram.

This is the Daelim factory repair publication for the Cordi configuration identified in the specification table by the SE50E 49.5cc engine. Its repair depth and reliance on specialty pullers, holders, electrical test equipment, and brake-service tools make it best suited to experienced mechanics and well-equipped owners. Frame- and engine-serial location drawings are included, but the manual defines coverage by vehicle and engine type rather than by a published model-year or serial-number range.

Engine, Fuel, and Drivetrain Repair Depth

The engine chapters go beyond routine tune-up information. They cover removal of the power unit, top-end disassembly, piston and ring installation, cylinder wear inspection, crankcase separation, crankshaft and bearing replacement, transmission inspection, and reassembly. The engine-removal section also distinguishes work that can be completed with the engine in the frame - including the carburetor, oil pump, A.C. generator, CVT, and top end - from crankshaft and crankcase-bearing repair that requires engine removal.

Fuel and lubrication coverage follows the Cordi's actual two-cycle layout. The manual addresses the PA35 carburetor, air cleaner, float chamber, throttle valve, automatic fuel valve, inlet-pipe reed valve, oil tank, oil-level switch, oil lines, and oil-pump control cable. It includes troubleshooting for hard starting, unstable idle, insufficient output, overheating, excess smoke, and lubrication faults without reducing the material to a generic maintenance checklist.

Chassis, Brakes, and Electrical Diagnosis

Chassis procedures cover body-panel removal order, wheels and bearings, tire work, fork disassembly and assembly, steering races, rear suspension, and both brake designs used on the scooter: a front hydraulic disk brake and rear mechanical drum brake. The hydraulic section includes fluid replacement and bleeding, pad replacement, disk inspection, caliper overhaul, and master-cylinder repair, supported by wear limits and component-specific torque data.

Electrical chapters provide factory test coverage for battery condition and charging output, headlight voltage, regulator/rectifier circuits, generator coils, ignition peak voltage, coil resistance, pulse-generator output, ignition timing, CDI operation, starter-motor internals, the starter relay, and switch continuity. Fault-isolation charts address no-start, low- and high-speed performance, CVT operation, steering, suspension, brakes, fuel and oil gauges, and starter faults.

Factory Data, Tools, and Diagrams

Reference material includes maintenance schedules, standard and component-specific torque tables, capacities and approved lubricants, adjustment data, electrical test values, dimensional standards, and service limits. The specialized-tool table ties part numbers to specific jobs, including the float level gauge 07401-001000, clutch spring compressor 07960-KM10000, crankcase puller 0751-00003, and rotor puller 0750-00006.

Labeled visual references include the Oil System Drawing, Charging Device Location and circuit, Ignition Devices Location, Starting Devices Location, the body-cover removal-order chart, and the full Wiring Diagram with color-code legend and switch-continuity tables. Major mechanical sections also open with exploded or system views for component identification before repair work begins.

The manual specifically warns that the two-stroke piston-ring gaps must register with their stopper pins and the piston crown mark must face the correct direction; a ring riding on a pin can be damaged during assembly. It also flags oil-line bleeding after lubrication-system service because trapped air can lead to engine sticking, while grease or oil on CVT belt and pulley surfaces can impair drive engagement. Support the scooter securely during engine removal, isolate the starting circuit before starter service, and follow the publication's fuel, battery, brake-fluid, and rotating-drive precautions.
