## Summary description

Replacement crankshaft designed for the GEKO CG81041B 3 kW engine-driven water pump. This spare part fits the pump's internal combustion engine assembly and transfers piston motion to the pump mechanism. Intended for repair and maintenance of GEKO 3 kW water pumps, it ensures mechanical connection between engine and pump for reliable water transfer and service restoration.

## Long description

Replacement crankshaft designed for the GEKO CG81041B 3 kW engine-driven water pump. This crankshaft is intended to restore the mechanical connection between the internal combustion engine and the pump mechanism so that piston motion is converted reliably into pump action. The component is made to fit the specified GEKO 3 kW water pump engine assembly and is intended for maintenance and repair tasks where a worn, bent or damaged crankshaft prevents normal water transfer.
Advantages
The crankshaft provides a direct, bolt-in replacement for the corresponding GEKO engine assembly, ensuring alignment of piston and connecting rod movement with the pump drive. By replacing a faulty crankshaft you reduce vibration and restore smooth mechanical operation without altering original pump performance characteristics. The part supports standard engine tolerances and mounting points for straightforward installation and predictable mechanical behaviour during pump operation.
Suitable for
 Repair of GEKO 3 kW engine-driven water pumps with damaged crankshafts
 Maintenance of pump engine assemblies requiring replacement of internal rotating components
 Workshops and technicians performing engine rebuilding or component-level service on small 3 kW water pumps
 Field repairs where restoring pump mechanical function is needed for water transfer tasks
Key specifications
 Compatibility: designed for GEKO 3 kW engine-driven water pump engine assembly
 Function: converts piston reciprocating motion to rotational drive for pump mechanism
 Material: engineered metal alloy suitable for engine crankshaft applications
 Mounting: machined bearing journals and mounting surfaces matched to original engine geometry
 Operational role: internal rotating component subject to engine RPM and load from pump operation
How to use
Installation should be performed by a qualified technician or experienced mechanic familiar with small engine disassembly. Remove the engine cover, drain oil if required, and disassemble connecting rods, pistons and related components to access the crankcase. Replace the defective crankshaft with the new unit, ensuring correct bearing placement, clearances and lubrication. Reassemble the engine in reverse order, refill oil to specified level and verify timing and alignment before test running the pump under no-load conditions and then under operational load.
Usage recommendations
Use OEM-specified engine oil and recommended bearings during assembly, adhere to manufacturer torque values for fasteners, and perform break-in runs at moderate load to confirm smooth operation. If excessive vibration or abnormal noises occur after installation, stop operation and inspect alignment, bearing condition and mounting fasteners.
