Description

Caterpillar Backhoe Loaders, Excavators, Track-Type Tractors, Motor Graders, Skid Steer Loaders 2006 Technical Manual

If you are turning wrenches on a D8T, 320D, or 140M, you already know the problem. Aftermarket specs are garbage. A torque value pulled from a forum gets you a snapped bolt or a blown seal. You need factory data—the same numbers Caterpillar engineers used when they bolted that machine together. This 2006 Caterpillar Backhoe Loaders, Excavators, Track-Type Tractors, Motor Graders, Skid Steer Loaders 2006 Technical Manual is the real deal: 1314 pages of performance specs, production curves, and attachment data straight from Peoria.

Track-Type Tractor Specifications and Production Data

That D6R you are rebuilding? Page 73 gives you the ground pressures, power shift travel speeds, and direct drive drawbar pull curves. The handbook breaks out bulldozer blade options with SAE capacity definitions and job condition correction factors—so you can estimate production without guessing. Rippers? Adjustable parallelogram, radial, fixed—all three are diagrammed with tip selection charts and seismic wave velocity data for ripping production estimates. Winches get their own section with Paccar and Allied features, plus physical and operating specs. Waste handling configurations are listed for each Track-Type Tractor model. No fluff, just numbers you can trust.

Motor Grader: All Wheel Drive and Scarifier Data

Motor Graders in this edition cover standard and global versions, travel speeds, and All Wheel Drive (AWD) specs. Need to mount a scarifier or ripper/scarifier? The handbook includes application sections and production formulas. Extreme slope operation tables tell you exactly what the machine can do before you take it up a grade. Work tools are listed for each series—so you know which attachments are compatible without cross-referencing outdated bulletins. Every spec is from the 2006 factory release, not a third-party reprint.

Skid Steer Loader and Multi Terrain Loader Compatibility

Skid Steer Loaders get their own chapter with features, specifications, performance data, and dimensions. Multi Terrain Loaders follow with work tool compatibility lists. The attachment section runs deep: augers, cold planers, landscape tillers, trenchers, vibratory compactors, brooms, stump grinders, angle blades, backhoes, material handling arms, snow blowers, wheel saws. If you are adding a hydraulic attachment to a 259D, this manual tells you the hydraulic flow requirements and mounting dimensions. Do not trust an online chart—get the OEM page.

Excavator Lifting Capacity and Bucket Specification

Page 201 (approximate—the PDF bookmarks are consistent) gives lifting capacities at ground level for one-piece boom, variable adjustable boom, and hydraulic adjustable boom configurations. Bucket capacity definitions, curl and crowd forces, bucket specifications, and working weights are included. Long reach, super long reach, telescopic stick, demolition arrangements—all covered with range dimensions and major component weights. Cycle time estimating charts and production estimating tables let you bid a job with factory-backed numbers. Front shovel specs for Belgium-sourced models like M318C MH and M322C MH are also in the section.

3 Reasons to Use OEM Documentation Over Aftermarket

First, torque specs. Aftermarket manuals often round values or omit tightening sequences. This handbook reproduces the exact values from Caterpillar’s engineering release—no reinterpretation. Second, production data. The charts for estimating ripping production or earthmoving are calibrated to Cat machines under controlled conditions. Third, compatibility. When you look at work tool attachment lists or bucket capacity tables, you are seeing the same data a dealer parts counter uses. That is the difference between a machine that runs and one that costs you a week of downtime.

ESX Control Override? Get the Hydraulic Flow Data Instead

This manual does not cover electronic control unit diagnostics—it is a performance handbook, not a service manual. What it does give you is the mechanical and hydraulic data you need to set up, operate, and maintain the machine. Need to match an excavator bucket to a specific arm length? The bucket specifications section has the answers. Want to know ground pressure for a D8R on swamp pads? Look in the Track-Type Tractor ground pressure table. For electronic troubleshooting, you need the Service Manual. For everything else, this is the reference.

Does this manual cover repair procedures or only performance specs?

Performance specs only. It is a technical manual for estimating production, selecting attachments, and verifying machine capabilities. For repair procedures, you need the corresponding Service Manual for your specific model.

What torque values are listed?

Torque values are not listed as a separate table. The handbook focuses on drawbar pull, hydraulic pressures, capacities, and dimensional data. For fastener torque specs, refer to the model-specific Operation and Maintenance Manual or Service Manual. This covers the performance envelope, not the bolt-by-bolt breakdown.

Related manuals that complement this handbook include the 2011 Filter and Fluid Application Guide 4th Edition for fluid specs, the 2013-2014 Caterpillar Fast Moving Parts Catalog for part numbers, and the Caterpillar Hydraulic Cylinder and Seal Reference Guide for seal kits. For a primer on how manual transmissions work in older tractors, see this Manual Transmission overview. If you are rebuilding a powertrain, understanding the Manual Transmission fundamentals helps with diagnosing gear train issues.
