BH-Motor Kohler gasket set for K241 K301 K321 10/12/14 hp engines — full head, base & auxiliary seals

BH-Motor new gasket set restores proper sealing for Kohler K241, K301 and K321 10/12/14 hp engines used in walk-behind mowers.

This comprehensive gasket kit is engineered to fit Kohler small engines and several equivalent OEM part numbers, making it a practical service pack for routine rebuilding, leak repair, or preventive maintenance. The set replaces aging, compressed, or damaged seals and gaskets that commonly cause oil or compression loss. It’s supplied to match the dimensions and hole patterns of the original Kohler components and compatible aftermarket references like Gravely and OREGON numbers listed in the product features.

Which engine models and part numbers does this kit fit?

The gasket set is specifically sized for Kohler K241, K301 and K321 engines rated at 10, 12 and 14 horsepower. It is also intended as a replacement for cross-referenced part numbers used by other manufacturers, helping simplify parts sourcing for older machines.

• Compatible engine models: Kohler K241, K301, K321 (10/12/14 hp)
• Cross-reference replacements: Gravely 014766, 03422850-403
• OEM Kohler equivalents: 47 004 01, 47 755 08-S
• Designed to match original bolt patterns and sealing surfaces

What gaskets and seals are included, and how do they improve engine function?

The kit contains the essential head, base, and auxiliary gaskets required during a top-end service or full teardown. Replacing these parts removes warped or hardened material that can cause oil weepage, coolant or air leaks, and loss of compression that affects performance.

• Includes head gasket, base gasket and auxiliary seals for valve cover and intake areas
• Restores proper sealing surfaces and compression consistency
• Helps stop oil and air leaks that reduce engine efficiency
• Useful when replacing head bolts, inspecting valves, or reconditioning the top end

How difficult is installation and what should a DIYer expect?

Installation difficulty depends on experience; a mechanically inclined DIYer with basic tools can complete the job, while complex diagnostics or machining work should be left to a shop. The gaskets align with factory holes, but careful cleaning, proper torque sequences, and new fasteners where needed are important for a lasting seal.

• Recommended skills: basic engine disassembly and torque wrench use
• Prep required: clean mating surfaces and remove old gasket material
• Follow Kohler torque specs and sequence for head bolts
• Consider replacing head bolts and inspecting valves during service

What materials and quality characteristics should you expect?

The gaskets are produced from materials intended for small-engine service—compressed fiber and elastomer blends where appropriate—to balance conformability and heat resistance. They are made to match the original sealing thicknesses to preserve compression and component clearances.

• Construction: multi-layered gasket materials for heat and oil resistance
• Thicknesses match factory specs to retain correct clearances
• Cut and punched to align with factory bolt and port locations
• Packaged to prevent damage and maintain form before installation

Who this is for: This BH-Motor gasket set is aimed at homeowners, groundskeepers, and small-engine technicians servicing walk-behind mowers with Kohler K241/K301/K321 engines. It’s practical for anyone performing a top-end rebuild, replacing leaking gaskets, or preparing a used engine for reliable service. If you need OEM-equivalent fitment with cross-reference compatibility for Gravely and OREGON numbers, this kit streamlines repairs and parts replacement without hunting down individual components.
