Important Notes

• Verify part number 576407101 before ordering
• Confirm compatibility with your specific Husqvarna equipment model and engine configuration
• The supplied product information identifies this component as a Base Gasket
• The exact engine components sealed by this gasket are not further identified in the supplied product information
• Do not assume this gasket is specifically a cylinder-to-crankcase gasket, crankcase-base gasket, engine mounting gasket, carburetor-base gasket, or another particular base sealing configuration unless confirmed by the applicable Husqvarna parts information
• The exact dimensions, thickness, material, coating, temperature rating, pressure capability, compression characteristics, bolt-hole pattern, and passage configuration are not identified in the supplied product information
• Gasket thickness can be important to the original engine configuration; do not substitute another gasket based solely on a similar shape or approximate dimensions
• Compare the original gasket's part number, shape, thickness where applicable, bolt-hole locations, passage openings, sealing surfaces, and installation orientation
• Even small differences in gasket thickness, opening position, port alignment, or sealing geometry can affect fit, sealing, and engine operation
• Inspect both mating surfaces for warping, cracks, corrosion, scoring, gouges, impact damage, damaged threads, or other conditions that could prevent proper sealing
• If the original gasket failed, determine whether the failure was caused by overheating, loose fasteners, distorted mating surfaces, improper assembly, abnormal pressure, or another underlying engine problem
• Carefully remove old gasket material without gouging or damaging the mating surfaces
• Prevent gasket fragments, abrasive particles, dirt, or cleaning residue from entering the crankcase, cylinder, intake, transfer passages, or other internal engine areas
• Make sure all gasket bolt holes, ports, and passages align correctly before final assembly
• Do not install the gasket folded, torn, wrinkled, shifted, doubled, or incorrectly oriented
• Do not trim, cut, enlarge openings, punch additional holes, stack multiple gaskets, or otherwise modify the base gasket to force compatibility
• Do not automatically apply RTV, gasket maker, adhesive, grease, or another sealing compound unless specifically required by the applicable Husqvarna service procedure
• Base gaskets are commonly disturbed during major engine disassembly; replace the gasket whenever required by the applicable service procedure rather than relying on a damaged or compressed gasket
• If this gasket is used at a cylinder base, inspect associated cylinder, piston, piston rings, connecting rod, crankshaft, bearings, seals, and intake/exhaust components as appropriate during service
• Follow the applicable service information for the correct fastener sequence, tightening procedure, and torque specifications
• This listing is for the base gasket; do not assume that additional gaskets, seals, O-rings, cylinders, pistons, rings, fasteners, adhesives, or sealing compounds are included unless specifically stated
• Shut off the equipment, disconnect the applicable power source, and allow the engine and exhaust components to cool before beginning service
• After installation and engine reassembly, verify proper gasket positioning, fastener security, sealing, absence of leakage, and overall engine operation before returning the equipment to normal service
