Thwaites Yanmar Exhaust Stud - OEM Number: T52797

The Thwaites Yanmar Exhaust Stud (OEM T52797) is a direct replacement fastening component designed for use on a range of Thwaites site dumpers fitted with Yanmar diesel engines. It is used within the exhaust system assembly to securely mount exhaust manifolds, pipes, silencers, and related components while maintaining correct alignment and sealing under high-temperature operating conditions.

Manufactured to OEM specifications, this exhaust stud is engineered for strength, heat resistance, and durability in demanding construction environments. It is designed to withstand continuous thermal cycling, vibration, and exhaust system loading commonly encountered in heavy-duty dumper applications.

• Secures exhaust system components to the engine or manifold assembly
• Maintains correct alignment of exhaust pipes and silencers
• Helps ensure reliable sealing of exhaust gaskets and joints
• Designed to withstand high temperatures and vibration
• Supports long-term exhaust system stability during machine operation

IMPORTANT INFORMATION

Always confirm the correct OEM part number, engine model, and dumper serial number before ordering, as thread dimensions, stud lengths, and exhaust mounting configurations may vary depending on engine type and machine production range. Damaged or incorrectly fitted exhaust studs can lead to exhaust leaks, gasket failure, vibration-related loosening, or premature exhaust system wear.
