Volvo L70H Wheel Loader Repair Service Pdf Manual

Repair & Service Manual with Wiring Diagrams Overview

The Volvo L70H Wheel Loader PDF Repair & Service Manual is the definitive technical authority designed for the professional maintenance and mechanical overhaul of this versatile H-Series machine. Covering all applicable serial number ranges, this manual provides the specific factory procedures required to maintain the patented TP-linkage (Torque Parallel), the fuel-efficient powertrain, and the advanced emissions control systems of the L70H series.

The Volvo L70H is a highly productive loader, known for its ability to handle a wide range of attachments thanks to the TP-Linkage. Powered by a clean-burning Volvo Turbo Diesel Engine, it features an intelligent Load-Sensing Hydraulic System that delivers power only when needed. Maintaining the variable displacement pumps, the AdBlue/DEF aftertreatment system, and the electronic machine management system is critical for maximizing uptime and fuel efficiency. This service manual is the essential reference for technicians diagnosing regeneration faults, calibrating the loader controls, and troubleshooting the Volvo Co-Pilot interface.

Machine & Powertrain Information

The Volvo L70H is powered by a high-torque Volvo 6-Cylinder Diesel Engine designed to meet strict Tier 4 Final / Stage V emissions standards. This manual covers the specific maintenance requirements for this power plant, including the common rail fuel system, the variable geometry turbocharger, the Diesel Particulate Filter (DPF), and the Selective Catalytic Reduction (SCR) system.

The machine utilizes a smooth-shifting Volvo Countershaft Transmission with Automatic Power Shift (APS) capabilities. Our manual guides you through the service of the torque converter, the directional clutch packs, and the heavy-duty axles with fully floating shafts and differential locks.
