131301000120A Drive Shaft Assembly Sany SAT40C Articulated Dump Truck Spare Parts

131301000120A Drivetrain Cardan Drive Shaft for Sany SAT40C Articulated Dump Truck

The 131301000120A Drive Shaft Assembly is a primary power transmission component configured for the drivetrain system of the Sany SAT40C articulated dump truck. Articulated haul trucks operating in severe mining, earthmoving, and quarrying environments generate massive torque that must be distributed across the articulation joint to the drive axles. Because the truck tractor and trailer sections continuously steer and pivot relative to each other, Sany implements this multi-segmented propshaft network. The 131301000120A assembly serves as a primary drive shaft segment, carrying rotating power safely along the frame while absorbing heavy angular and torsional stresses.

This assembly integrates two heavy-duty Flange Forks (60156379) to connect securely to the transmission, transfer case, or axle input flanges. It features cardan-style Universal Joints (131301000120A001) to manage angular deflection, and an integrated telescoping Splined Hub (131301000120A004) and Yoke Assembly (131301000120A003) slip-joint to absorb changes in distance. We supply the fully integrated 131301000120A 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.

131301000120A Assembly Component Parts List

Below is the detailed parts catalog breakdown of the drive shaft assembly as referenced in the Sany SAT40C technical manual. All listed components can be ordered individually for targeted field repairs or routine universal joint overhauls:

Note: Item index 5 is omitted in Sany’s original parts catalog, jumping from 4 to 6. This has been meticulously preserved below for catalog precision.

Features & Benefits of Our Cardan Drive Shaft

• High-Angle Cardan Deflection: The high-capacity Universal Joints (131301000120A001) 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 (131301000120A004) and slip yoke (131301000120A003) design to allow the shaft to expand and compress linearly during truck chassis osculation, preventing axial thrust from loading the drivetrain bearings.
• Mining Dust & Grit Exclusion: Equipped with a heavy-duty Dust Shelter / rubber bellows boot (60349400) that encapsulates the sliding splines, keeping out highly abrasive coal dust, silica, and water.
• Pre-Balanced Shaft Structure: This drive 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 zerk fittings on the U-joint crosses and slip spline to purge out contaminants.
3. Verify Chassis Model Sizing: Drive 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.
