131301000119A Power Take-off Drive Shaft Assembly Sany SAT40C Articulated Dump Truck Spare Parts

131301000119A Auxiliary Power Take-Off (PTO) Drive Shaft for Sany SAT40C

The 131301000119A Power Take-off Drive Shaft Assembly is a specialized mechanical power transmission component configured for the drivetrain system of the Sany SAT40C articulated dump truck. Articulated dump trucks require continuous, high-volume hydraulic flow to operate their heavy-duty steering rams and multi-stage body hoisting (tipping) cylinders under maximum payload conditions. This auxiliary PTO drive shaft bridges the physical gap between the transmission Power Take-Off output flange and the input shaft of the primary hydraulic pumps, delivering rotational mechanical torque across the truck’s central articulation pivot.

Because the tractor and trailer sections of the truck continuously osculate, steer, and pivot relative to each other, this drive shaft must handle extreme multi-dimensional movements. It utilizes dual cardan-style Cross Shaft Assemblies (131300000053A011) to manage angular deflection, and an integrated telescoping Splined Hub (131301000319A003) and Spline Shaft Fork (131301000319A004) slip-joint to absorb changes in distance. We supply the fully integrated 131301000119A 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.

Note: Item index 4 is omitted in the Sany original parts catalog, jumping from 3 to 5. This has been meticulously preserved below for catalog precision.

Features & Benefits of Our PTO Cardan Drive Shaft

• High-Angle Cardan Deflection: The dual high-capacity Cross Shaft Assemblies / Universal Joints (131300000053A011) 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 (131301000319A003) and slip yoke design to allow the shaft to expand and compress linearly during truck chassis osculation, preventing axial thrust from loading the hydraulic pump bearings.
• Mining Dust & Grit Exclusion: Equipped with a heavy-duty Dust Shield Assembly / rubber bellows boot (131301000319A005) that encapsulates the sliding splines, keeping out highly abrasive coal dust, silica, and water.
• Pre-Balanced Shaft Structure: This PTO shaft assembly is dynamically balanced at Sany factory tolerances to eliminate rotational vibration harmonics, preserving pump 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 5) and the spline fork (item 7) after service, ensure the alignment arrows stamped on the yokes are perfectly aligned to prevent severe rotational vibrations.
2. Maintain Grease Service Intervals: Heavy-duty mining PTO joints are subjected to high loads and moisture. Use high-quality lithium-complex grease (item 6) via the integrated zerk fittings on the U-joint crosses and slip spline to purge out contaminants.
3. Verify Chassis Model Sizing: PTO drive shafts, spline tooth counts, and flange bolt circles differ based on the automatic transmission and pump layouts. Please provide your Sany SAT40C’s chassis serial prefix so our technical team can verify exact part compatibility.
