Loncin Combustion Engines

Loncin engines — drives for construction and garden machinery

Loncin, a Chinese manufacturer, builds petrol engines for machine drives: four-stroke, air-cooled, OHV (Over Head Valve — valves in the head instead of the block, which lowers fuel use and running temperature). Across construction and garden machinery the brand runs roughly 5.5–15 hp at displacements of 120–400 cm³. Loncin engines are brought in to order, not held in stock.

G series and LC1P series — horizontal against vertical shaft

The model code states which way the crankshaft points — the first thing to settle. Codes opening with G carry a horizontal shaft, driving through a belt or a centrifugal clutch. Codes opening with LC1P — LC1P92F1 in garden tractors, for instance — carry a vertical shaft that turns a mower blade or a tractor transmission. The letter E marks electric start.

Choosing a Loncin engine as a replacement

A replacement is specified from the rating plate of the drive being removed:

• Shaft orientation — horizontal or vertical; nothing else counts until this matches.
• Power output — close to the outgoing unit, tolerance around 10%.
• Shaft diameter and length — commonly 19.05 or 25.4 mm, cylindrical with a keyway.
• Bolt pattern of the foot — it has to line up with the machine frame.
• Drive accessories — clutch, pulley or reduction gear often sold separately.

Where those agree, the swap takes 1–3 hours in the workshop. Plan the first oil change after roughly 20 operating hours and every 100 hours afterwards, with a check of the filters for combustion engines.
