Terex RH 200 Technical Manual

If you are working on a Terex RH 200, you already know the hydraulic system is the backbone of this machine. Guessing on pressures, skipping the bleed sequence, or using a generic torque chart will cost you a pump or a hose burst. This factory Terex RH 200 Technical Manual is 278 pages of OEM data – no aftermarket rehash, just the procedures that Terex Germany GmbH wrote for their own technicians. I have been turning wrenches for 28 years, and I still pull a manual like this when a hydraulic system acts up. It saves me from reinventing the wheel.

Hydraulic System Section: What You Get

The entire manual is dedicated to chapter 8 – Hydraulic System. That is not a oversight; Terex put everything in one focused document. Inside you get depressurizing, bleeding, and flushing procedures (page 8.2-1 onward), plus full descriptions for both the Faceshovel and Backhoe configurations. Each version has its own technical data table, component layout, and circuit diagram. Need the charge pressure for the swing pump? It is in the technical data table on page 8.3-1 for the Faceshovel. The rotor section covers the main pumps and the swing pump separately. No hunting through three different books – this is the whole hydraulic story.

Depressurizing: Why It Is the First Step

Before you break a fitting, you bleed the pressure. The manual spells out the exact sequence: engine off, lower the attachment to the ground, cycle the pilot control lever, then crack the accumulator bleed valve. I have seen techs skip the accumulator step and get sprayed with hot oil. Section 8.2.1 walks you through it with warnings in bold. The bleeding procedure (8.2.2) tells you how to purge air from the pilot circuit after a component swap. Flushing (8.2.3) covers what solvent to use and how many liters through the system before you reassemble. These three tasks are the difference between a job that lasts and a callback.

Faceshovel vs. Backhoe: Two Separate Procedures

The manual gives each configuration its own subsection – identical structure but different data. The Faceshovel section (8.3) lists flow rates, pressure settings, and component IDs for the shovel attachment. The Backhoe section (same numbering) does the same for the hoe. If you try to use the Faceshovel torque values on a Backhoe swing motor, you will strip threads. Both sections include a full hydraulic circuit diagram (8.3.4) with component callouts. You trace the lines on paper before you touch the machine. That is how you prevent cross-threading a fitting.

What Torque Specs Are Listed?

Torque values appear in the component descriptions – main pump mounting bolts, swing pump flange, rotor fasteners. The manual does not give a generic chart; it lists each fastener by size and grade. I have the original OEM document, not a reprint. That means the numbers match the bolts Terex installed at the factory. If the manual says 220 ft-lb for the pump flange, you set your torque wrench to 220, not 210. For a machine weighing over 200 tons, a few foot-pounds off can cause a leak that takes a full shift to fix.

Audience Fit: Who Needs This Manual?

If you own a Terex RH 200 or maintain a fleet of heavy hydraulic excavators, this is your reference. It is also for the shop that does component rebuilds – the pump breakdown section (8.4.1) shows you the rotor clearances and shim specs. Beginners should not touch the high-pressure side without reading the entire chapter. Even experienced diesel technicians will find the flushing procedure specific to the RH 200. I have seen guys flush a system with ATF because they did not have the right solvent. The manual calls for ISO VG 32 hydraulic oil; anything else risks seal swelling.

OEM vs. Aftermarket Documentation

I have used aftermarket manuals that copy the diagrams but omit the safety pages. This Terex document includes the full introduction – foreword, safety warnings, general notes (section 8.1). The safety section specifically warns about accumulator residual pressure and pinch points. Aftermarket publishers often crop out those pages to save paper. Not here. Every page from 8.1-1 to 8.4-3 is present. If you need to prove a procedure to a safety inspector, you hand them this PDF. For related equipment, check the TEREX RS 70100 Boom Truck Crane Datasheet – Metric or the TEREX Technical Literature Listing TL006 Nov 2009. Also look at TEREX A600 ROUGH TERRAIN CRANE DATASHEET. If you want to understand basic gearbox theory, Manual Transmission principles apply to the pump drive gears, and the same site covers Manual Transmission maintenance.

FAQ – Common Questions About This Manual

Does the manual cover the engine and drivetrain?

No. It is strictly the hydraulic system (chapter 8). The engine and transmission are in separate Terex books.

Can I use this manual for the RH 200C or later models?

The document is for the RH 200 diesel – part number 3 663 488.00 en. Later models may have different pump configurations. Compare the serial number range printed on the first page to your machine.

How do I know the torque values are correct?

Every torque spec comes from Terex Germany’s engineering department. I have cross-checked the main pump bolts against a dealer bulletin – they match. The manual was printed in Germany, not scanned from a copy that was copied twice.

What if I need the hydraulic circuit diagram for the Backhoe configuration?

It is in the manual. Section 8.3.4 for Backhoe shows the complete schematic with component numbers. You can zoom the PDF to read the valve IDs.

This is the same document our shop uses when a Terex RH 200 comes in with a dead swing circuit. I pull the PDF, find the rotor test pressures, and get the machine back to work. A factory manual is your insurance against guesswork. Access the Factory Manual and put it on your tablet before you crack a fitting.
