Volvo R70D Rigid Hauler Service Repair Manual 2005675D – PDF

Description

This Volvo R70D Rigid Hauler Service Repair Manual is the complete workshop reference for the R70D rigid haul truck, published by Volvo Construction Equipment under document number 2005675D. The 465-page manual covers every major assembly on the machine in the depth a working technician needs: the Detroit Diesel (MTU) 12V 2000 engine and its mounting, the Allison H 6620 ORS transmission with the Commercial Electronic Control (CEC5) shift system, the rear axle with differential and wheel planetary gearing, the hydrostatic steering circuit, the body hoist hydraulics, and the front and rear braking systems. Each component section includes removal, disassembly, inspection, assembly and installation procedures, backed by exploded views, cutaway illustrations, hydraulic schematics and electrical circuit diagrams.

The R70D service manual is organised by system rather than as a single narrative, so each chapter stands alone. That structure is useful on the shop floor: if the job is a rear axle rebuild, you turn to section 160 and work through differential disassembly, shimming, gear tooth pattern adjustment and planetary assembly without having to wade through unrelated material. If the fault is electronic, section 120-0072 takes you through the CEC5 shift system, solenoid activation tables, speed sensor resistance checks and the diagnostic fault code list. The document assumes familiarity with heavy equipment practice and directs the reader to the relevant engine or transmission manufacturers’ service manuals when work goes beyond the scope of this book.

What This Manual Helps You Do

This is a genuinely deep service manual, not a light maintenance guide. It supports the full range of jobs on the R70D: engine removal and reinstallation, transmission removal and reinstallation, driveline servicing, front and rear axle rebuilds, brake pack disassembly and seal replacement, ride cylinder charging with nitrogen, steering pump overhaul, steering valve rebuild, body hoist cylinder rebuild, body control valve servicing, and cab removal. System pressure test points are called out across the steering, body hoist and braking schematics, with the target pressures listed so you can diagnose a weak pump or a sticking relief valve rather than swapping parts.

The braking system section is particularly detailed. The rear oil-cooled disc brake packs are broken down to individual components, with wear limits for friction discs, splined plates and damper plates, plus instructions for measuring brake disc stack height and stamping the new height onto the piston housing for future reference. The treadle valve rebuild includes bench testing and the deadband adjustment procedure. The transmission CEC5 section contains the full solenoid activation table, gear-to-solenoid mapping, speed sensor resistance chart and an extensive diagnostic fault code list covering P-codes and U-codes. For anyone working on electronic shift or lockup faults, that combination is difficult to find in one place.

Why Correct Procedures and Specs Matter

Heavy haul trucks run at high pressures and heavy loads, and the difference between a correct repair and a guess is often expensive. The R70D manual spells out torque values for critical fasteners – driveline capscrews, wheel rim nuts, axle bolts, cylinder ends, brake caliper bolts – along with the assembly sequence for components that will not tolerate being put together in the wrong order. The differential adjustment section, for example, walks through pinion cage shimming, ring gear backlash, bearing preload and gear tooth pattern checking, with the specific tolerances listed for each step. Get that wrong and the axle will whine, overheat and fail long before its time. The manual also warns repeatedly about accumulator pressure, nitrogen charging and tyre inflation hazards, which is exactly the kind of safety context a technician needs before starting the job.
