High-Quality Replacement Driveline Parts by — PTC Drivelines
Fasteners are hardly ever the subject of maintenance until wear or an improperly rated bolt at a critical mounting point causes some type of component misalignment or unexpected downtime. PTC 3056 is made directly as a cross reference to Komatsu 01050-81475 – it has identical pitch, grip length and head dimensions and fits into the original mounting location, so no change to torque or alternate parts is necessary. The bolt is manufactured from high-tensile alloy steel and is heat-treated to the clamping strength required for heavy dozer assemblies that experience continuous vibration and load shifting.
In dusty, wet and abrasive environments such as mining and quarrying, untreated hardware will corrode quickly, and a corrosion-resistant surface coating protects the fastener from corrosion. PTC 3056 provides a uniform, grade-approved stock item for fleet maintenance teams administering regular maintenance or replacement of hardware as part of a fleet of multiple Komatsu D475A units, avoiding the risk of using generic fasteners of unknown grade.
