![Fiat Kobelco E30.2SR E35.2SR Repair Manual [Hydraulic Exavator]](https://youfixthis.com/wp-content/uploads/2015/10/2015-10-16_10-25-29-300x300.png)
This 620-page Fiat Kobelco E20SR, E22SR, E25SR Evolution repair manual PDF (OEM 604.13.249.00) puts the full factory workshop procedures for all three short-radius hydraulic excavators in your hands. You get hydraulic schematics with pressure test procedures, wiring diagrams for the whole electrical system, and page after page of exploded views covering attachments, upper slewing structure, and travel system teardown. A full troubleshooting section runs hydraulic and electrical faults to ground, and the engine gets its own chapter. Set the 1/4 PF hydraulic joints to 3.7 kg·m (26.8 lb·ft), and remember that one full turn on the main relief valve moves pressure 125 kgf/cm2 (1780 psi). No more chasing electrical gremlins with a multimeter and a prayer. Bookmarked and keyword-searchable; find the spec, fix the machine, and get back in the seat.

Fiat Kobelco E20SR EVOLUTION, E22SR EVOLUTION, E25SR EVOLUTION Common Problems This Manual Covers
Fiat Kobelco E20SR Evolution hydraulic hose leaking at fittings, bucket loses pressure under load
Inspect hose ends and PF joints for weeping oil with the engine off. Retorque 1/4 PF joints to 3.7 kg·m (26.8 lb·ft) and 3/8 hydraulic hoses to 5 kg·m (36.2 lb·ft) using the torque tables on page 58. Replace any hose with a cracked cover, then run the engine 5 minutes to bleed air.
Manual Section: Maintenance p. 58Boom and arm slow, dig force weak, relief valve screaming at full stick
Test pump pressure at the P1 and P2 ports; you want 230 kgf/cm2 (3270 psi) per page 165. If low, adjust the main relief valve, remembering one full turn moves pressure 125 kgf/cm2 (page 81), then torque the lock nut to 2 kgf·m (14 lbf·ft). Confirm the tank holds its full 27 L before condemning the pump.
Manual Section: Hydraulic System Troubleshooting p. 445Engine cranks slowly or will not start after sitting overnight in cold weather
Check battery terminals and the ground strap for corrosion, then load-test the battery before blaming the starter. Verify fuel in the 25 L tank and bleed the lines to the injection pump. If it still cranks slow, work the starting-trouble charts in the troubleshooting section beginning on page 445.
Manual Section: Engine Troubleshooting p. 445Slew motor weeps oil at the flange and house rotation feels jerky
Check the flange bolts for looseness and clean the motor housing to trace the leak. Inspect the shaft seal for external leakage and replace it if oil returns. Test slew relief pressure at the motor: one full adjuster turn changes it 100 kgf/cm2 (1420 psi) per page 81, and torque the lock nut to 3.5 kgf·m (25 lbf·ft).
Manual Section: Slewing Motor TroubleshootingWater temperature gauge climbs into the red during heavy digging, coolant boiling over
Drain the cooling system, flush it, and refill with the full 2.7 L capacity noted on page 34. Blow packed debris out of the radiator core with low-pressure air and check fan belt deflection. Pressure-test the cap and hoses; if the gauge still climbs, follow the engine charts starting on page 445.
Manual Section: Engine Troubleshooting p. 445Frequently Asked Questions
What are the torque specifications for the main pump bolts on the Fiat Kobelco E20SR, E22SR, and E25SR EVOLUTION models?
The main pump (B1) is secured with two capscrews (B5) M10 X 30. The tightening torque for these bolts is 8.7 kgf·m (63 lbf·ft) when applying Loctite #262. p. 310
What are the replacement specifications for hydraulic lines and seals?
Rubber products such as hydraulic hoses, O-rings, and oil seals deteriorate with age and must be replaced at periodical intervals or at every overhaul. It is recommended to designate important hoses critical for safety as Very Important Parts (V.I.P.) and replace them periodically. p. 75
What is the standard valve clearance for the engine on the E20SR, E22SR, and E25SR EVOLUTION models?
The standard valve clearance for both intake and exhaust valves on all models is 0.15 to 0.25 mm. p. 511
What is the tightening torque for the cylinder head bolts on the 3TNE74 engine?
The tightening torque for the cylinder head bolts on the 3TNE74 engine is 6.0 to 6.5 kgf·m (using M9 X 1.25 thread). p. 569
What is the standard oil capacity for the travel motor reduction unit?
The standard oil volume for the travel motor reduction unit is 350 cc (21.4 cu·in) of gear oil SAE #90. p. 415
