Inside the Idu line: how a KARYA goes from crate to road in seven stations

IDU, Abuja — The crates arrive from Semarang stacked two high: chassis, cargo body, wheels, wiring, lamps, and — already built and bench-tested at VIAR's factory — the engine. From here, a KARYA cargo tricycle takes shape across seven stations on the Zeetin assembly line.

Station 1 — Kit inspection

Nothing enters the line until the stores team has checked every crate against VIAR's packing list and recorded the engine and chassis numbers. A kit with a missing or damaged part is quarantined until a replacement is confirmed.

Station 2 — Chassis and rear axle

The bare frame is lifted onto a trolley. Technicians fit the rear axle, leaf-spring suspension and rear wheels — the assembly that carries a payload of 449 kg on the 150 RLn and 700 kg on the 200 Ln.

Station 3 — Engine installation

The water-cooled engine is lowered into the frame and its mounts torqued to specification. The radiator and coolant lines are connected and the drive is coupled to the rear axle, with the reverse-gear assembly in place.

Station 4 — Front end and electrics

Front forks, headlamp, handlebar and throttle, clutch and brake cables, the CDI unit and the wiring loom follow. Electric and kick starters are tested before the body is fitted.

Station 5 — Cargo body and finishing

The steel bed — 1.80 by 1.25 metres on the 150 RLn, 2.01 by 1.26 on the 200 Ln — is bolted down, followed by seat, mudguards, mirrors, tail lamps and trim. The unit is cleaned and inspected panel by panel in its factory colour.

Station 6 — Quality check and road test

Each tricycle is started, checked for leaks and electrics and driven inside the complex. Only then are its numbers entered in the finished-goods register, making every KARYA traceable from kit to customer.

Station 7 — Handover

At collection the buyer inspects the unit with a Zeetin officer, confirms the engine and chassis numbers against the invoice and signs the Handover Checklist. The tricycle leaves with its Warranty Card, owner's manual, tool kit and free-service schedule.
