131301030026A Transmission Shaft Assembly Sany SAT40C Articulated Dump Truck Spare Parts

131301030026A Drivetrain Cardan Transmission Shaft for Sany SAT40C

The 131301030026A Transmission Shaft Assembly is a primary power transmission and torque-distribution component configured for the drivetrain system of the Sany SAT40C articulated dump truck. Mining haul trucks operate under continuous, heavy loads, generating massive torsional torque across their drivetrain axles. Because the truck tractor and trailer sections continuously steer and pivot relative to each other, Sany implements this multi-segmented propshaft network. The 131301030026A assembly functions as a primary transmission shaft segment, carrying rotating power safely along the frame while absorbing heavy angular and torsional stresses.

This assembly integrates two flanged yoke ends to connect securely to the transmission, transfer case, or axle input flanges. It features cardan-style Universal Joints (131301000116A001) to manage angular deflection, and an integrated telescoping Splined Hub (131301030037B004) and Yoke Assembly (131301030037B001) slip-joint to absorb changes in distance. We supply the fully integrated 131301030026A assembly as well as individual replacement universal joints, spline shafts, dust boots, and flange yokes. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

Features & Benefits of Our Transmission Drive Shaft

• High-Angle Cardan Deflection: The dual high-capacity Cross Shaft Assemblies / Universal Joints (131301000116A001) are engineered using premium forged steel spider crosses and needle bearings, allowing for high angular movements without binding.
• Telescoping Distance Compensation: Includes an induction-hardened Splined Hub (131301030037B004) and slip yoke (131301030037B001) design to allow the shaft to expand and compress linearly during truck chassis oscillation, preventing axial thrust from loading the drivetrain bearings.
• Mining Dust & Grit Exclusion: Equipped with a heavy-duty Dust Shield Assembly / rubber bellows boot (131301030037B003) that encapsulates the sliding splines, keeping out highly abrasive coal dust, silica, and water.
• Pre-Balanced Shaft Structure: This transmission shaft assembly is dynamically balanced at Sany factory tolerances to eliminate rotational vibration harmonics, preserving axle input shaft seals.

Ordering & Technical Maintenance Guidelines

1. Observe Phase Alignment on Slip Joints: Drivetrain yokes must remain in-phase. When reassembling the splined hub (item 6) and the slip yoke (item 4) after service, ensure the alignment arrows stamped on the yokes are aligned to prevent severe rotational vibrations.
2. Maintain Grease Service Intervals: Heavy-duty mining drive shaft joints are subjected to high loads and moisture. Use high-quality lithium-complex grease (item 7) via the integrated grease port on the slip spline and the U-joint crosses to purge out contaminants.
3. Verify Chassis Model Sizing: Transmission shafts, spline tooth counts, and flange bolt circles differ based on the automatic transmission and drivetrain layouts. Please provide your Sany SAT40C’s chassis serial prefix so our technical team can verify exact part compatibility.
