Thwaites 9/10 Tonne Bottom Pin Weld-In Boss - OEM Number: K10337

The Thwaites 9/10 Tonne Bottom Pin Weld-In Boss (OEM K10337) is a direct replacement heavy-duty pivot mounting component designed for use on Thwaites 9 and 10 tonne site dumpers. It forms part of the dumper articulation or tipping assembly, providing a reinforced housing for pivot pins and associated bushings within high-load structural areas of the machine.

Manufactured to OEM specifications, this weld-in boss is engineered for high strength, durability, and resistance to wear under demanding construction and earthmoving conditions. It is designed to be permanently welded into the chassis or body structure, restoring secure pivot mounting points during repair or refurbishment work.

FUNCTION AND OPERATION

• Provides a reinforced mounting point for pivot pins and bushes
• Supports articulation and tipping assembly movement
• Helps maintain structural alignment within the pivot system
• Designed to withstand heavy load, shock, and vibration forces
• Suitable for repair and refurbishment of worn pivot housings

TECHNICAL DETAILS

• OEM Part Number: K10337
• Type: Weld-in boss / pivot pin housing
• Function: Structural pivot mounting component
• Application: Thwaites 9 and 10 tonne dumper articulation and tipping systems
• Construction: Heavy-duty machined steel boss
• Design: Weld-in replacement boss for pivot and pin assemblies

Weld-in bosses of this type are commonly used in dumper chassis and tipping gear repairs where original pivot housings have become worn, ovalised, or damaged through prolonged heavy-duty use.

TYPICAL APPLICATIONS

Suitable for a range of Thwaites equipment, including:

• Thwaites 9 tonne site dumpers
• Thwaites 10 tonne site dumpers
• Dumper articulation pivot systems
• Tipping gear and hydraulic body pivot assemblies
• Chassis and structural repair applications

Heavy-duty weld-in pivot bosses are widely used during plant refurbishment and structural repair work to restore correct pivot alignment and reduce excessive movement within articulation systems.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, and pivot dimensions before ordering, as weld-in boss sizes, wall thicknesses, and bore specifications may vary depending on dumper model and production range. Incorrect installation or poor welding practices may result in premature wear, pivot misalignment, structural cracking, or failure under load.
