469-4312 4694312 CAT K110 Vertical Pin Adapter RH

Part No.:469-4312 4694312 CAT K110 Vertical Pin Adapter RH          469-4312 / 4694312

Product Name: K110 Vertical Pin Adapter, Right Hand (RH)

Brand Compatibility: Caterpillar (CAT) Original & Aftermarket Replacement Parts

The 469-4312 vertical pin adapter is a professional two-strap weld-on bucket corner adapter belonging to CAT K110 tooth system series, specially designed for the right-hand corner position of excavator and loader buckets. Adopting vertical pin (hammerless) installation structure, it perfectly matches standard K110 bucket teeth and vertical lock pins, realizing fast, hammer-free assembly and disassembly. This adapter serves as the core connecting component between bucket body and bucket teeth, undertaking impact load, wear resistance and structural reinforcement functions during harsh earthmoving operations.

Hammer-Free Vertical Pin Design: Unlike conventional horizontal pin adapters that require hammer striking for pin assembly, this upgraded vertical pin structure supports straightforward top-to-bottom pin fitting with no hammer impact required. It eliminates part distortion and pin hole damage brought by harsh hammer blows, cuts down assembly labor hours and routine maintenance workload, and remarkably prolongs the service lifespan of pin holes and matched locking pins.

Customized Right-Hand Corner Fit: This adapter adopts optimized arc profile and stress-bearing angle specially customized for the right corner of construction machinery buckets. It boasts perfect fitting performance with the original bucket edge welding radian, delivers full coverage protection for bucket easily worn corner sections, and effectively stops bucket edge crack, surface wear and structural deformation caused by long-hour digging, material loading and hard rock breaking operations.

Reinforced Dual-Strap One-Piece Structure: Adopting seamless one-piece casting with double side straps, this adapter obtains boosted overall structural stiffness. Its thickened load-bearing base can evenly distribute instantaneous concentrated impact stress produced during heavy-duty excavation, preventing structural bending, crack and brittle breakage even under continuous high-load working circumstances.

OEM Exact Size Compatibility: All production processes follow strict Caterpillar original equipment dimension specifications. It achieves full compatibility with genuine K110 series bucket teeth, vertical lock pins and other matched parts. Customers can realize direct plug-and-play replacement with original 469-4312 components without any cutting, grinding or other secondary modifications.

This K110 RH vertical pin adapter adopts high-strength low-alloy steel as raw material, produced via lost wax investment casting integral forming process, with no welding seam on the whole body. After multiple heat treatment processes including quenching and tempering, the product achieves balanced hardness and toughness:

High surface hardness: Excellent anti-wear performance to cope with long-term friction with sand, gravel, rock and soil;

Strong core toughness: Resists instantaneous strong impact and vibration during excavation, preventing brittle fracture;

Overall anti-fatigue performance: Adapt to frequent cyclic working loads of construction machinery, reducing failure rate in long-duration continuous operation.

Meanwhile, the surface is treated with anti-rust and anti-corrosion coating, adapting to complex outdoor working environments such as rainy days, muddy construction sites and mine sites, effectively delaying oxidation and corrosion.

Widely applicable to medium and large CAT excavators, wheel loaders and engineering buckets equipped with K110 tooth system, covering mainstream construction, mining and earthmoving equipment models. It supports direct welding replacement for original bucket corner adapters of matched CAT machinery.

Earthmoving, foundation excavation and road construction projects;

Gravel quarrying, rock breaking and mine loading operations;

River dredging, site leveling and heavy-duty bulk material handling;

Harsh working conditions with severe wear and frequent impact loads.

This adapter is a weld-on type component, which needs to be firmly welded to the right corner of the bucket before assembling bucket teeth and vertical pins;

Match with standard K110 vertical lock pins for installation; do not use mismatched pins to avoid loose connection;

Check welding firmness and pin locking state regularly during daily equipment inspection to avoid falling off during high-load operation.
