Crankshaft for GEKO petrol rotary tiller models G84000/G84001

Replacement crankshaft compatible with GEKO petrol rotary tiller models G84000 and G84001. This mechanical component transfers the reciprocating motion of the piston to the drive shaft, restoring rotational movement required for the tiller’s gearbox and tines. It is intended for use in the engine powerhead during repair or maintenance when the original crankshaft is worn, bent, or damaged and needs replacement to re-establish correct engine timing and smooth operation.

Advantages

The crankshaft is manufactured to match the mechanical dimensions and mounting points of the original part for straightforward installation without modification. Made from hardened steel with precision-machined journals and balancing, it provides reliable transfer of power and consistent rotational balance. Using a correctly sized replacement crankshaft reduces vibration, prevents premature bearing wear, and helps restore compression and timing for improved engine starting and steady idling.

Suitable for

• Repair of GEKO petrol rotary tiller models G84000
• Repair of GEKO petrol rotary tiller models G84001
• Engine overhaul and powerhead maintenance
• Replacement after crankshaft bending, scoring, or excessive wear

Key specifications

• Compatibility: GEKO petrol rotary tillers G84000 and G84001
• Function: converts piston reciprocation to crankshaft rotation
• Material: hardened steel construction with precision-machined journals
• Finish: balanced and ground bearing surfaces for reduced vibration
• Application: designed for use in small single-cylinder petrol engine powerheads

How to use

Prior to installation, inspect the engine block, main bearings, connecting rod bearing, and seals for wear or damage and replace any worn components. Remove the cylinder head and piston assembly as required to access the crankshaft according to the tiller’s service manual. Fit the crankshaft into the engine block, ensuring journals and bearings are correctly seated and lubricated with engine assembly oil. Reassemble the piston, cylinder head, timing components, and ancillary parts, then verify correct clearances and timing before completing the assembly and performing a test run.

Usage recommendations

Use genuine-quality lubricants and follow torque specifications from the service manual. After installation, perform a break-in procedure with gradual load increases and monitor for abnormal vibration, noise, or oil leaks. Replace related seals and bearings when installing the crankshaft to ensure long-term reliability.
