Takeuchi TB014/TB016 Excavator Workshop Manual Set, 2005 (P/N CC4E002)

The Takeuchi volume covers the excavator installation and machine systems, while the Kubota and Yanmar volumes extend the reference into internal engine repairs. Both engine books cover additional engine variants, so their general specifications must be matched to the Takeuchi installation.

Injection-pump scope: Yanmar refers internal YPES-ML pump disassembly, assembly and adjustment to a separate pump manual, which is not included. Kubota provides pump testing procedures but directs internal pump repairs to an authorized pump service shop.

PDF Navigation and Diagram Readability

Text search and navigation: Body text is searchable, but some diagram labels are not. Embedded bookmarks provide section access, although some entries lead to incorrect pages. Small wiring-diagram labels are readable when enlarged; viewing an entire diagram at page-fit size makes these details difficult to read.

The download contains one printable PDF with 577 pages. The publication totals above include five cover/back-cover pages and 13 otherwise blank pages, along with the original front matter and section dividers.

Excavator Systems and Engine Repair Coverage

This is a selected content preview. Additional subjects include biodegradable hydraulic-oil changeover and the optional travel alarm.

• Machine assemblies: Engine mounts, radiator assemblies and hydraulic pump couplings are illustrated alongside removal and installation procedures for major components.
• Hydraulic units: Pump, control valve, pilot valve and solenoid valve sections combine construction details with disassembly, inspection and assembly information.
• Travel and slew: Step-by-step procedures cover travel motor overhaul, slew motor service and swivel joint resealing, with separate swivel-joint sections for each excavator.
• Undercarriage and attachments: Rubber and steel crawler service, track adjusters, rollers, idlers, slew bearings and hydraulic cylinders receive component-specific treatment.
• Diesel engines: Cylinder heads, valves, pistons, connecting rods and crankshafts are covered alongside compression testing, fuel injection timing adjustments and cooling-system service.
• Diagnostic references: Wiring diagrams, hydraulic circuit diagrams, troubleshooting flowcharts, performance curves, cross-sectional views and dimensional drawings support system identification and fault tracing.

The Takeuchi manual specifies trained, qualified service personnel as its audience. The engine volumes likewise assume servicing knowledge and access to appropriate measuring equipment and special tools.

From Symptoms to Component Inspection

Hydraulic fault isolation: Troubleshooting charts address weak operation, attachment drift, uneven travel and slew faults. Their checks distinguish possible cylinder leakage from control-valve faults, helping technicians identify the next inspection before removing an assembly.

Configuration differences: Pilot-control connection tables distinguish ISO and JCB layouts, including the selector-valve arrangement. The TB016 swivel-joint section also explains the selector circuit serving the blade and track-width adjustment, rather than treating both machines as hydraulically identical.

Assembly Details and Repair Precautions

Component alignment: Exploded views show the relationship between engine mounts, radiator assemblies and pump couplings. Wear-limit tables for track rollers, idlers and slew bearings provide inspection criteria for deciding which components require attention during teardown.

Cylinder and valve work: The hydraulic-cylinder section includes seal replacement, leakage checks and dimensioned drawings for service jigs. Control-valve instructions identify matched spools and bodies, with replacement requirements that matter when assessing whether individual parts can be reused.

Hydraulic recommissioning: The manual explains air bleeding and tank pressurization after hydraulic work. Omitting tank pressurization can cause pump cavitation and shorten pump life; the original description’s claim of certain, immediate destruction overstates the warning.

Because these machines involve high-pressure hydraulics and pinch points, review the manufacturer’s safety instructions before teardown. The track-adjuster section specifically warns about pressurized grease and the risk of the discharge valve being expelled.

Selected Hydraulic Flow and Valve-Clearance Data

The Takeuchi specification tables list an auxiliary hydraulic flow rate of 32.6 L/min for both excavators. This provides a concrete example of the machine-level performance data included alongside the repair procedures.

For cold-engine intake and exhaust valve clearance, the Kubota D782-E2B reference specifies 0.145–0.185 mm, while the Yanmar 3TNV70 reference specifies 0.15–0.25 mm. These separate values illustrate why the correct engine section matters when selecting adjustment data.
