High-Quality Replacement Driveline Parts by — PTC Drivelines
PTC 3012 is manufactured as a cross-reference OEM fastener replacement for Komatsu 01050-61260, used to secure the spider assembly bearing caps to the yoke on wheel loader and haul truck driveline joints. Produced from high-tensile alloy steel and processed through a controlled heat treatment cycle, this bolt is engineered to hold clamping load under the constant vibration and torque cycling present at universal joint connections. Thread tolerances are machined to match OEM pitch and length specifications, ensuring the bolt seats correctly without cross-threading or requiring re-tapping during installation.
Surface finishing includes a corrosion-resistant coating suited to exposure on unpaved mining and quarry sites, helping maintain thread integrity across extended service intervals between driveline inspections. Each batch is checked for tensile strength and dimensional accuracy against Komatsu WA470 / WA480 before packing. Manufactured under ISO 9001:2015 quality controls, PTC 3012 gives maintenance teams a dependable fastener option for spider and yoke assemblies without compromising clamping reliability during heavy-duty operation.
