Part Number: 545107605
Category: Lawn & Garden Equipment Replacement Parts
Type: Flat Impeller Crankshaft Assembly – Replacement Lawn & Garden Equipment Engine Crankshaft Component

The Husqvarna 545107605 Flat Impeller Crankshaft Assembly is a replacement engine rotating component designed for compatible Husqvarna lawn and garden equipment. Identified by the supplied Flat Impeller designation, the crankshaft assembly serves as a primary rotating member within the applicable engine configuration, converting piston movement into rotational motion and providing the mechanical interface required to transfer engine power to associated components. It is suitable for replacing a bent, scored, excessively worn, damaged, seized, or otherwise unserviceable crankshaft assembly when Husqvarna part number 545107605 is specified.

Important Notes

• Verify part number 545107605 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine model, serial range, and crankshaft configuration
• The supplied product information identifies this component as a Flat Impeller Crankshaft Assembly
• The exact Husqvarna equipment and engine models associated with this crankshaft assembly are not identified in the supplied product information
• The precise meaning and application of the Flat Impeller designation should be verified against the applicable Husqvarna engine parts information
• Do not assume this crankshaft fits all Husqvarna equipment using a similar engine displacement, engine family, or impeller configuration
• Do not assume this component is specifically for a blower, vacuum, mower, trimmer, edger, tiller, or other particular equipment type unless confirmed by the applicable parts information
• The exact overall length, shaft diameters, journal dimensions, stroke, taper, keyway configuration, threads, bearing surfaces, impeller interface, material, and balance specifications are not identified in the supplied product information
• Similar-looking crankshafts can differ in stroke, journal dimensions, shaft length, taper, keyway, threads, bearing locations, drive-end configuration, and engine compatibility
• Compare the original crankshaft's part number, dimensions, journal locations, shaft ends, tapers, keyways, threads, bearing surfaces, connecting-rod interface, and output configuration
• Do not substitute a crankshaft based solely on approximate length, shaft diameter, engine size, or visual appearance
• Because this item is identified as a crankshaft assembly, verify the exact supplied assembly contents before ordering
• Do not assume that the connecting rod, piston, piston rings, bearings, seals, keys, flywheel, impeller, fasteners, or other internal engine components are included unless specifically stated
• Inspect the associated connecting rod, piston, cylinder, crankcase, bearings, bushings, seals, flywheel, impeller, keys, and drive components for wear or damage before installing the replacement crankshaft
• A damaged crankshaft may result from bearing failure, connecting-rod failure, insufficient lubrication, overheating, severe impact, sudden rotating-component stoppage, excessive engine speed, or internal engine damage
• If the original crankshaft is bent, scored, seized, or broken, determine the underlying cause before installing a replacement
• Inspect crankshaft journals and mating components for scoring, discoloration, overheating, metal transfer, excessive clearance, or lubrication-related damage
• Inspect the crankcase and bearing locations for cracks, distortion, excessive wear, damaged bearing seats, or alignment problems
• Check the connecting rod and piston assembly for damage resulting from the original crankshaft failure
• Where an impeller or other rotating component attaches to the crankshaft, inspect that component for impact damage, imbalance, cracks, deformation, or damaged mounting surfaces
• A damaged or unbalanced rotating component can place excessive stress on a replacement crankshaft and engine bearings
• Replace applicable bearings, seals, gaskets, retainers, or other wear components when required by the appropriate engine service procedure
• Maintain proper cleanliness during internal engine assembly; dirt, abrasive material, or metal debris can quickly damage new crankshaft and bearing surfaces
• Apply the correct assembly lubricant and engine lubrication according to the applicable service information
• Verify correct bearing installation, crankshaft end play, connecting-rod installation, component orientation, clearances, and fastener torque where applicable
• Maintain the correct timing relationship between the crankshaft and associated engine components during reassembly
• Do not grind, weld, heat, straighten, machine, modify journals, alter keyways, change shaft dimensions, or otherwise modify the crankshaft to force compatibility
• Internal engine repair requires accurate assembly and measurement; use the applicable manufacturer service specifications where available
• This listing is for the Flat Impeller Crankshaft Assembly; do not assume that the complete engine, piston, connecting rod, bearings, seals, gaskets, flywheel, impeller, ignition components, or mounting hardware are included unless specifically stated
• Shut off the equipment, allow the engine to cool completely, drain fluids where required, and disconnect the applicable spark plug, battery, or other power source before performing internal engine service
• After installation and engine reassembly, verify proper crankshaft rotation, internal clearances, lubrication, sealing, timing, component alignment, and rotating-component clearance
• Confirm the engine operates without binding, excessive vibration, abnormal knocking, rubbing, oil leakage, overheating, unusual noise, or rotating-component interference before returning the equipment to normal service.
