High-Quality Replacement Driveline Parts by — PTC Drivelines
The PTC 1040 Spider Assy Front is a highly accurate part of the driveline that has been designed as a direct cross-reference to Komatsu 561-20-61100, which is used in the production of the front propeller shaft assembly of heavy-duty rigid dump trucks. This spider assembly is manufactured using high-grade forged alloy steel and undergoes a controlled heat treatment, which enables it to sustain the high torque, shock loading and sustained articulation in mining and earthmoving operations.
Each unit of PTC 1040 is lubricated internally in three stages with a three-stage sealing mechanism and self-locked bearing cups, which exclude the need to frequently re-grease and reduce equipment downtime. Dimensional accuracy and dynamic balancing are ensured to fit within OEM fitment specifications to install without modification. Supported by the quality processes of ISO 9001:2015 and the OEM-equivalent testing, PTC 1040 provides a high level of reliability, long service life and stable dependability to fleet operators and equipment maintenance professionals operating Komatsu HD785 series drive line systems.
