New Holland E30, E35 Common Problems This Manual Covers
New Holland E30 or E35 complete loss of hydraulic movement and severe boom drift under load.
Test the hydraulic pump working pressure at the main test port. If the reading falls below 23.0 MPa, check the delivery flow. Verify each pump outputs 38.4 L/min as shown on page 181. Inspect the internal piston assembly for wear and replace if necessary.
Manual Section: Hydraulic System Troubleshooting p. 181Swing brake fails to engage after hours of operation and upper machine structure rotates unexpectedly when parked.
Inspect the swing lock brake assembly for worn friction plates. Measure the parking brake releasing pressure to ensure it stays between Min 2.0 and Max 6.4 MPa. Verify the parking brake torque holds at 1022 Nm or more as specified on page 212.
Manual Section: Slewing Motor & Swivel Joint Troubleshooting p. 212Engine stalls rapidly when the hydraulic loader is engaged or turns over slowly after a hot shutdown.
Check the throttle linkages and verify the engine low idling speed. Adjust the governor setting to exactly 1250±25 rpm as listed on page 35. If the engine still stalls under heavy hydraulic load, inspect the fuel filter assembly for vapor lock or clogging.
Manual Section: Engine Troubleshooting p. 35Boom cylinder drifts downward while holding a suspended load and hydraulic oil leaks from the rod wiper.
Inspect the boom cylinder seals for damage. Replace the U-ring, back-up ring, and wiper ring. When reassembling the boom cylinder, torque the piston to exactly 1150 Nm as detailed on page 303. Apply fresh hydraulic fluid to all seals before final assembly and testing.
Manual Section: Hydraulic System Troubleshooting p. 303Frequently Asked Questions
What are the replacement specifications for Hydraulic pump (main flow)?
The manual specifies the nominal delivery flow for the hydraulic pump. For Piston pump P1 + P2, the delivery flow is 38.4 L/min (10.1 gal/min) x 2. For Gear pump P3, it is 20.6 L/min (5.44 gal/min). The manual does not provide specific replacement specifications for 'main flow' as a trigger for pump replacement, but rather for individual components. p. 181
What are the replacement specifications for Fuel filter assembly?
The fuel filter element should be replaced at specified intervals, or if it is damaged, excessively dirty, or oily. Applicable fuel filter part numbers are 119802-55800 for 3TNV82A, 4TNV88, and 4TNV98(T), and 123907-55800 for 4TNV106(T). The tightening torque for the fuel filter is 20~24 N·m (2.0~2.4 kgf·m). p. 596
What is the standard valve sink for the intake and exhaust valves on a 3TNV82A engine?
For a 3TNV82A (2-valve head) engine, the standard intake valve sink is 0.35~0.55 mm with a limit of 0.8 mm, and the standard exhaust valve sink is 0.30~0.50 mm with a limit of 0.8 mm. p. 746
What is the tightening torque for the main bearing cap bolts on a 4TNV106(T) engine?
For a 4TNV106(T) engine, the main bearing cap bolts should be tightened to a torque of 186.2~205.8 Nm (19.0~21.0 kgf·m). Lubricating oil should be applied to the thread portion and seat surface before tightening. p. 756
