Terex TSV-70, TSV-80 2011 Service Manual

You’ve got a Terex TSV-70, TSV-80 2011 Service Manual on the bench, and the machine is waiting. The aftermarket book you pulled off the shelf says “tighten securely” for the lift arm pivot bolts. That’s not a spec, that’s a liability. This 102-page OEM manual from Terex, printed in 2011, gives you the actual numbers. Critical torque values are listed right in Chapter 2, page 2-1. No third-party reprints, no generic diagrams – just the factory data a dealer tech relies on.

Factory Torque Specifications for TSV-70 and TSV-80

Every fastener on these skid steers has a specific torque – from the wheel lug nuts to the hydraulic pump mounting bolts. Chapter 2 breaks it down for both single-speed and two-speed TSV-70/80 variants. Page 2-1 lists the critical specs for the drive motors, charge pump, and lift arm control valve. If you’re replacing a hydraulic line or resealing a cylinder, you need these numbers. The manual also lists required service tools so you’re not scrambling for a crowsfoot you don’t own.

What Does the Circuit Diagrams Chapter Cover?

Chapter 3 – Circuit Diagrams – is worth the price alone. It includes hydraulic filtering, cooling, auxiliary, drive, and two-speed drive circuits. Each diagram is clearly labeled with component IDs and flow paths. The lift arm control valve schematic on page 3-5 shows every port and solenoid. When a customer’s machine won’t curl the bucket, you trace it here, not by guessing and swapping parts. Understanding the hydraulic drive circuit is fundamental – it’s not like a Manual Transmission where you can feel the gears. You need a map.

18 Chapters Covering Every System

This isn’t a condensed owner’s manual. It’s a full service manual with 18 chapters: Product Safety, Technical Specifications, Circuit Diagrams, Maintenance, Machine Controls, Operator Enclosure, Chassis & Fuel Tank, Radiator and Oil Cooler, Hydraulic Reservoir, Loader Drive Controls, Hydraulic Pumps and Motor, Engine, Hydraulic Cylinders & Quick Attach, Lift Arm/Linkage/Bushings, Hydraulic Component Service Procedures, Troubleshooting, Lubricant and Fuel Specs, and Service Aids & Supplements. That’s every nut, bolt, and line on the TSV-70 and TSV-80.

Each chapter has step-by-step procedures. The loader drive controls section breaks down the hydrostatic drive circuit in a way that even a guy who only knows a Manual Transmission can follow. The bleeding and charging procedures for the accumulator are in Chapter 6 – don’t skip that if you’re working on the operator enclosure seals.

Get the Right Fuel and Lubricant Specs

Using the wrong hydraulic oil or fuel filter will cost you a day of flushing and a customer who won’t pay. Chapter 17 – Lubricant and Fuel Specs – gives you the exact viscosities, API classifications, and capacities. It also lists the fuel system requirements. If you’re in San Antonio like me, the summer blend matters. Don’t guess. Open the manual.

Troubleshooting: Factory-Approved Diagnostic Steps

Chapter 16 – Troubleshooting – walks you through common problems: no drive, weak lift, overheating, electrical gremlins. Each symptom has a cause list and a test procedure. You start at step one, you don’t jump to replacing a pump you didn’t test. That’s how you waste time and money. The manual also includes service aids and supplements in Chapter 18 – special tools and specifications for the 2-speed option.

Why OEM Matters

Aftermarket manuals get specs wrong. I’ve seen misprinted torque values cause cylinder leaks and stripped threads. This is a direct PDF of the Terex factory document, with original page numbering and part numbers. The 2011 publication year covers both TSV-70 and TSV-80 models. If you’re working on the Fuel system – injectors, lines, tank – Chapter 7 gives you the chassis and fuel tank removal procedure. No guesswork.

How many pages is this manual?

It is 102 pages, including the front and back covers.

Does it cover the two-speed TSV-80?

Yes. Chapter 2 has separate specifications for single-speed and two-speed variants. The circuit diagrams also include the two-speed drive circuit. Chapter 4 (Maintenance) also covers the two-speed shift motor. I’ve used it myself on a 2011 TSV-80 with the 2-speed option – the wiring and hydraulic schematics matched exactly. If you’re doing a full engine overhaul or hydraulic pump replacement, the steps are the same for both machines. The manual specifies differences where they exist – for example, critical torque values for the drive motor mounting bolts are listed separately on page 2-2 for two-speed models. You won’t be left wondering.
