## Summary description

Replacement piston pin designed for petrol-driven rotary lawn mowers with a 51 cm cutting width, branded Faworyt and compatible with Loncin engines.

Suited for repair and maintenance of small 4-stroke mower engines where this pin size and fitment are specified.

## Long description

Piston pin for 51 cm petrol rotary mower drive, Faworyt (compatible with Loncin) 51cm is a replacement wrist pin intended for use in small 4-stroke petrol lawn mower engines with a 51 cm cutting width. It fits between the piston and connecting rod to transmit the reciprocating motion of the piston to the crankshaft. The part is suitable for routine repairs and maintenance where this specific pin diameter and length match the engine's requirements, helping to restore proper piston alignment and engine operation.
Advantages
This piston pin is manufactured to meet dimensional requirements typical for 51 cm petrol rotary mowers and is compatible with engines of similar design, including Loncin-compatible units. The component is built from hardened metal to withstand reciprocating loads and high temperatures in the combustion chamber area. Using a correctly sized replacement pin reduces piston wobble and excessive wear on the piston and connecting rod, contributing to longer engine service life when installed and lubricated properly.
Suitable for
 Repair of 4-stroke petrol rotary lawn mowers with a 51 cm cutting width
 Replacement of worn or damaged piston pin in compatible engines
 Maintenance tasks during engine rebuilds or overhauls
Key specifications
 Application: piston/connecting rod wrist pin for small 4-stroke mower engines
 Compatibility: designed for Faworyt branded 51 cm petrol rotary mowers and engines with equivalent pin dimensions (Loncin-compatible)
 Material: hardened steel suitable for high-load reciprocating use
 Function: transmits piston motion to connecting rod; resists wear and heat
How to use
Install this piston pin during engine repair or rebuild following the engine manufacturer's service manual and safety procedures. Remove the cylinder head and piston assembly as required, align the piston with the connecting rod, and insert the pin through the piston boss and connecting rod small end. Secure with the appropriate retaining clips or circlips in the piston grooves, ensuring clean seating and correct orientation. Verify smooth articulation of the piston on the pin and check for correct clearance before final assembly of the cylinder, head gasket, and related components.
Usage recommendations
Use genuine-quality lubricants or assembly grease on the pin during installation to reduce initial wear. Always inspect piston, piston bore, and connecting rod for scoring or damage and replace other worn components as needed. Confirm dimensional fit (diameter and length) against the original part or engine specifications before installation.
