New Holland EC 215 Excavator (1999) Service Manual (P/N 73179384.00 us)

This factory service manual covers the 1999 New Holland EC 215 hydraulic excavator. Published as the EC 215 Technical Handbook (P/N 73179384.00 us), it includes machine-specific service data for serial numbers 72 1502 and up.

Search, Bookmarks, and Diagram Detail

Text search and diagram labels: Most workshop text is searchable, and embedded bookmarks open the technical sections. The Home Page bookmark points to a separate file. The hydraulic schematics and machine wiring sheets lack searchable text. Zoom in to read small connector, pin, and wire labels. Some lines and labels on the superstructure hydraulic schematic remain faint when enlarged.

The download contains one printable, 716-page PDF in English, with bilingual English–German service data. The total includes the main cover, the section index, and 714 pages across 11 sections, including the bound-in references and appendices.

Track and Gearbox Repair, Hydraulic Testing, and Electrical Diagnosis

These are selected workshop topics. The handbook also includes examples of starter and alternator testing and guidance on hard-facing wear surfaces.

• Undercarriage and superstructure: Track chain and idler repair, roller and sprocket replacement, duo-cone seal assembly, and swing bearing removal and installation.
• Travel and swing gearboxes: Planetary gearbox overhaul, bearing and shim inspection, and wet multi-disk brake disassembly, resealing, and reassembly.
• Hydraulic repair: Working and swing pump checks, control valve testing, cylinder overhaul, and system bleeding and flushing after component failure.
• Electrical diagnostics: Machine wiring diagrams, On-Board Diagnostic Computer (ODC) fault tables, PCS 3 power-limit checks, and EDS tester procedures.
• Engine installation: Removal and installation of the 6BTA 5.9-C-160 engine and hydraulic pumps, with resilient coupling inspection and engine alignment.
• Equipment and workshop references: Bucket and grab changes, hydraulic pipe and hose connections, repair welding, and sealing and corrosion-protection materials.

The handbook is written for experienced service mechanics who work with excavator systems, precision measuring equipment, and specialized lifting and repair tools.

Track, Swing Bearing, and Gearbox Work

The undercarriage section includes component dimensions, weights, wear limits, and tightening torques. It explains how incorrect track chain orientation accelerates wear on the bushings and sprocket teeth. Swing bearing coverage includes superstructure removal and checking gear tooth clearance.

The F44 travel and S10 swing gearbox references include sectional and exploded assembly drawings, bearing preload adjustments, brake disk inspection, and seal replacement. The same references also illustrate other gearbox models.

Hydraulic Pressure Checks and Cylinder Overhaul

Pressure-test tables distinguish working-pump relief, power boost, swing pressure cutoff, and safety-valve settings. Separate hydraulic schematics for the superstructure and undercarriage accompany explanations of the six-section control block, boom regeneration, and parallel travel.

The pump procedures cover proportional demand control, output loss, and swing feed pressure. The tool references identify the PCS/EDS tester, solenoid valve tester, proportional valve measuring adapter, and equipment for measuring control spool stroke.

Cylinder procedures cover piston rod removal, guide bushing work, and seal replacement. The handbook directs mechanics to a specialist workshop for assessment and reworking of damaged cylinder components. Flushing guidance addresses metal contamination after component failure, and the bleeding section explains how trapped air can damage seals and guide components through the diesel effect.

PCS 3, ODC, and Wiring Faults

The PCS 3 reference shows how the A10 load-limit controller, A100 control panel, engine speed pickup, and Y10 proportional valve work together. Functional diagrams, pump output curves, and valve characteristics support checks of power limiting, operating modes, and stored faults.

Mechanics can use the ODC fault tables alongside electrical test specifications and hydraulic troubleshooting tables to select checks before dismantling components. For example, the fault table identifies sensor circuit and proportional valve faults associated with reduced power. The wiring section provides connector assignments, fuse layouts, and cable harness views. The CENTRY reference explains warning indications and when Cummins service may request a flash-code readout.

Engine Repair Scope and Workshop Safety

Engine coverage centers on removal, installation, and the resilient coupling. The handbook refers internal engine repair to the engine manufacturer's separate manual. The welding and materials references cover welder qualifications, material-dependent repair methods, and surface crack testing.

Safety: High-pressure hydraulics, raised equipment, and spring-loaded brakes require trained personnel, suitable supports, and the specialized tools specified for the work.

Examples of Track Wear Limits and Bolt Torques

For the B60 track chain, the wear table gives a four-link measurement of 760 mm when new and 781 mm at the stated wear limit. The track pad torque table specifies 568 N·m (419 lb-ft) for lightly oiled M18 × 1.5 bolts on the triple-grouser pads.
