130202000093A270 Rear PTO Assembly Sany SAT40C Articulated Dump Truck Spare Parts

130202000093A270 Rear Power Take-Off (PTO) Assembly for Sany SAT40C

The 130202000093A270 Rear PTO Assembly (Rear Power Take-Off Group) is an essential mechanical drive component configured for the drivetrain system of the Sany SAT40C articulated dump truck. Articulated haul trucks operating in severe mining, earthmoving, and quarrying environments require massive, reliable hydraulic flows to actuate their multi-stage body hoist cylinders and heavy-duty steering rams. The Rear PTO assembly serves as the direct mechanical link, tapping high-torque rotational energy from the transmission/drivetrain gears and routing it directly to the auxiliary hydraulic pump drives.

This assembly incorporates three high-strength splined Shaft Assemblies (130202000093A256), a high-load radial Ball Bearing (130202000093A258) to manage high rotational forces, and three precise steel retaining snap rings to lock the shafts and bearings axially. We supply the fully integrated 130202000093A270 PTO assembly as well as individual replacement gears, shafts, bearings, and retaining circlips. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

130202000093A270 Assembly Component Parts List

Below is the detailed parts catalog breakdown of the rear PTO assembly as referenced in the Sany SAT40C technical manual. All listed components can be ordered individually for targeted field repairs or overhaul maintenance:

Features & Benefits of Our Rear PTO Assembly

• High-Torque Power Transmission: The precision-machined spline Shaft Assemblies (130202000093A256) are forged from high-tensile alloy steel to handle intensive torsional force transfers under peak hydraulic pressures.
• Premium Radial Bearing Support: Features a high-capacity radial Ball Bearing (130202000093A258) designed to manage high rotational speeds and radial stresses, reducing internal friction and heat.
• Positive Axial Spline Retention: Utilizes heavy-duty spring steel snap rings (130202000093A257 & 130202000093A259) to lock the shafts and bearing securely into their axial design coordinates, preventing lateral movement and gear misalignment.
• Durable Splined Interface: Drive spline teeth are induction-hardened to resist abrasive wear and micro-galling during sudden hydraulic pump load changes.

Ordering & Technical Maintenance Guidelines

1. Check Drive Splines for Wear: Mechanical PTO splines are subjected to harsh shock loads. During transmission overhauls or auxiliary pump service, inspect the spline profiles of the Shaft Assemblies (item 1) for backlash, stepped wear, or pitting. Worn shafts should be replaced.
2. Always Install New Retaining Snap Rings: Retaining snap rings (items 2 & 4) lose their spring tension once stretched during disassembly. Always replace them with new, high-tensile circlips during reassembly to ensure they seat tightly in their housing grooves.
3. Verify Chassis Model Sizing: PTO splines, mounting patterns, and shaft lengths can vary depending on the automatic transmission series and hydraulic pump configuration. Please provide your Sany SAT40C’s chassis serial prefix so our technical team can verify exact part compatibility.
