A dead Mechatro fault code at 6 a.m. with a crew waiting is exactly the problem this book was written for: the 864-page New Holland Kobelco E265, E305 workshop manual PDF, factory document 604.13.674, covering both hydraulic excavators from safety plates to final drive rebuild. Wiring diagrams trace every harness through the Mechatro controller, and hydraulic schematics map the pilot circuit, control valve, and swing and travel motors alongside troubleshooting trees keyed to self-diagnosis failure codes. Repair chapters walk the undercarriage piece by piece: swing bearing, track adjuster, front idler, rollers, and track chain. When you chase a weak function, confirm the return and make-up circuit holds 249 to 490 kPa, then torque the PF1 port to 200 to 250 Nm on reassembly. Nobody around has wrenched a Mechatro system before? This text-searchable PDF answers the questions you would otherwise ask no one, so the diagnosis lands right the first time.

New Holland Kobelco E265, E305 Common Problems This Manual Covers
New Holland Kobelco E265 attachment movements weak or not working, hydraulic power drops under load
Work the hydraulic troubleshooting chart on page 384. Main relief pressure should be 34.3 MPa at P1 and P2 (24.5 MPa at optional P4); if not, inspect or replace the pump and also inspect the pump coupling. Pilot relief pressure should be about 4.5 MPa, otherwise replace the relief valve. With pilot pump primary pressure and the pilot valve P port inlet both about 4.5 MPa (a low inlet means inspect or replace the pilot line filter), pilot valve secondary pressure should be approx. 2.9 MPa for the attachment and 2.3 MPa for travel; if not, inspect or replace the pilot valve.
Manual Section: Hydraulic System Troubleshooting p. 384Travel speed stuck in first gear, will not shift into second speed
The travel circuit has a 2-speed change with auto 1st (low) speed return, which drops back to low speed / high torque at heavy duty (page 123), so a machine that falls to first under load may be working as designed. On the E265 compare against 4.0 km/h in first speed and 6.0 km/h in second speed (page 65), and check the travel pilot valve secondary pressure, approx. 2.3 MPa (page 384).
Manual Section: Hydraulic System Troubleshooting p. 123Machine creeps downhill on slopes and travel parking brake will not hold position when stopped
On the E265 the travel motor relief valve set pressure is 310 bar at 1.2 L/min cracking and 353 bar at 40 L/min total flow (page 279). The parking brake torque is 470 Nm static and 370 Nm dynamic, with a minimum parking brake release pressure of 14 bar (page 279). The travel circuit also carries motor overrun protection that prevents overrunning of the travel motor on a downhill slope, and an auto parking brake (page 123).
Manual Section: Hydraulic System Troubleshooting p. 279ROM DATA FAILURE or MECHATRO SET ERROR on the multidisplay after replacing the mechatro controller or engine control unit
The mechatro controller must be adjusted when it is replaced, when the Engine Control Unit (C-3) is replaced, or when ROM DATA FAILURE is displayed, alone or alternating with MECHATRO SET ERROR (page 361). Warm up the engine, turn the air-con switch off and stop the engine, then remove resistors R1 = 1.1 kΩ and R2 = 820 Ω from resistance E-16 near the pressure drain switch; if they stay connected the controller cannot carry out the adjustment. Pressure sensors should signal 0.5 to 4.5 V on a 5 V supply (page 120).
Manual Section: Operational Performance Test p. 361Track chain loose and jumping off the idler, undercarriage rattles and clunks during travel
Wash the soil off the track area thoroughly before measuring, then check track sag (A) against the 320 to 350 mm specification and supply grease to valve (1) to adjust track tension (page 777).
Manual Section: Repair Instructions - Undercarriage p. 777Frequently Asked Questions
How do I reset or clear the fault codes on a New Holland Kobelco E265 or E305?
To clear the contents of the trouble history, first display the trouble history mode. Then, press the work mode select switch and the buzzer stop switch concurrently for 10 seconds or more. When the erasing is completed, the "NO ERROR" message will be displayed. p. 116
What do the warning or fault codes mean on a New Holland Kobelco E265 or E305?
The diagnostic light provides a first evaluation of the importance of the trouble. A light that is inoperative means no troubles or minor ones; a light that stays ON constantly indicates a significant trouble that allows travel to a diagnostic center; and a flashing light indicates a serious trouble requiring prompt repair. p. 454
What are the torque specifications for the track roller bolts on a New Holland E265?
The tightening torque for the lower roller bolts (4) on the track frame (2) is 397 Nm. p. 779
What is the procedure for bleeding air from the hydraulic pump on the E265 and E305?
To bleed air from the hydraulic pump, remove the air bleeding plug from the top of the pump and fill the pump housing with hydraulic oil. Temporarily tighten the plug, start the engine, and run at slow idle. Slightly loosen the plug to bleed air until hydraulic oil oozes out, then securely tighten the plug. p. 466
What is the gear oil capacity of the swing reduction unit on the New Holland Kobelco E305?
The swing reduction unit on the E305 takes approximately 10.5 L of gear oil; check the gear oil level before starting operation. p. 595
Is this New Holland Kobelco E265 manual a download or a disc?
